+# ⚠️ PLEASE READ ⚠️
+
+## Questions or Features
+
+If you have a question or want to request a feature, please **DO NOT SUBMIT** a new issue.
+
+Instead please use the relevant Discussions section's category:
+- 🙏 [Ask a question](https://github.com/nginx-proxy/nginx-proxy/discussions/categories/q-a)
+- 💡 [Request a feature](https://github.com/nginx-proxy/nginx-proxy/discussions/categories/ideas)
+
+## Bugs
+
+If you are logging a bug, please search the current open issues first to see if there is already a bug opened.
+
+For bugs, the easier you make it to reproduce the issue you see and the more initial information you provide, the easier and faster the bug can be identified and can get fixed.
+
+Please at least provide:
+- the exact nginx-proxy version you're using (if using `latest` please make sure it is up to date and provide the version number printed at container startup).
+- complete configuration (compose file, command line, etc) of both your nginx-proxy container(s) and proxied containers. You should redact sensitive info if needed but please provide **full** configurations.
+- generated nginx configuration obtained with `docker exec nameofyournginxproxycontainer nginx -T`
+
+If you can provide a script or docker-compose file that reproduces the problems, that is very helpful.
+
+## General advice about `latest`
+
+Do not use the `latest` tag for production setups.
+
+`latest` is nothing more than a convenient default used by Docker if no specific tag is provided, there isn't any strict convention on what goes into this tag over different projects, and it does not carry any promise of stability.
+
+Using `latest` will most certainly put you at risk of experiencing uncontrolled updates to non backward compatible versions (or versions with breaking changes) and makes it harder for maintainers to track which exact version of the container you are experiencing an issue with.
+
+This recommendation stands for pretty much every Docker image in existence, not just nginx-proxy's ones. 
+
+Thanks,
+Nicolas

 ### Usage
 
 To run it:
 
-    $ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy
+```console
+docker run --detach \
+    --name nginx-proxy \
+    --publish 80:80 \
+    --volume /var/run/docker.sock:/tmp/docker.sock:ro \
+    nginxproxy/nginx-proxy:1.6
+```
 
-Then start any containers you want proxied with an env var `VIRTUAL_HOST=subdomain.youdomain.com`
+Then start any containers (here an nginx container) you want proxied with an env var `VIRTUAL_HOST=subdomain.yourdomain.com`
-
-    $ docker run -e VIRTUAL_HOST=foo.bar.com  ...
-
-The containers being proxied must [expose](https://docs.docker.com/reference/run/#expose-incoming-ports) the port to be proxied, either by using the `EXPOSE` directive in their `Dockerfile` or by using the `--expose` flag to `docker run` or `docker create`.
-
-Provided your DNS is setup to forward foo.bar.com to the a host running nginx-proxy, the request will be routed to a container with the VIRTUAL_HOST env var set.
-
-### Docker-compose
-
-Currently this does not work with the new v2 syntax of docker-compose (due to not being compatible with the new network overlay see [#304](https://github.com/jwilder/nginx-proxy/issues/304)). It does work when using the old docker-composer syntax.
-
-
-### Multiple Ports
-
-If your container exposes multiple ports, nginx-proxy will default to the service running on port 80.  If you need to specify a different port, you can set a VIRTUAL_PORT env var to select a different one.  If your container only exposes one port and it has a VIRTUAL_HOST env var set, that port will be selected.

-
-### Multiple Hosts
-
-If you need to support multiple virtual hosts for a container, you can separate each entry with commas.  For example, `foo.bar.com,baz.bar.com,bar.com` and each host will be setup the same.
-
-### Wildcard Hosts
-
-You can also use wildcards at the beginning and the end of host name, like `*.bar.com` or `foo.bar.*`. Or even a regular expression, which can be very useful in conjunction with a wildcard DNS service like [xip.io](http://xip.io), using `~^foo\.bar\..*\.xip\.io` will match `foo.bar.127.0.0.1.xip.io`, `foo.bar.10.0.2.2.xip.io` and all other given IPs. More information about this topic can be found in the nginx documentation about [`server_names`](http://nginx.org/en/docs/http/server_names.html).
-
-### Multiple Networks
-
-With the addition of [overlay networking](https://docs.docker.com/engine/userguide/networking/get-started-overlay/) in Docker 1.9, your `nginx-proxy` container may need to connect to backend containers on multiple networks. By default, if you don't pass the `--net` flag when your `nginx-proxy` container is created, it will only be attached to the default `bridge` network. This means that it will not be able to connect to containers on networks other than `bridge`.
-
-If you want your `nginx-proxy` container to be attached to a different network, you must pass the `--net=my-network` option in your `docker create` or `docker run` command. At the time of this writing, only a single network can be specified at container creation time. To attach to other networks, you can use the `docker network connect` command after your container is created:
 
 ```console
-$ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro \
+docker run --detach \
-    --name my-nginx-proxy --net my-network jwilder/nginx-proxy
+    --name your-proxied-app \
-$ docker network connect my-other-network my-nginx-proxy
+    --env VIRTUAL_HOST=foo.bar.com \
+    nginx
 ```
 
-In this example, the `my-nginx-proxy` container will be connected to `my-network` and `my-other-network` and will be able to proxy to other containers attached to those networks.
+Provided your DNS is setup to resolve `foo.bar.com` to the host running nginx-proxy, a request to `http://foo.bar.com` will then be routed to a container with the `VIRTUAL_HOST` env var set to `foo.bar.com` (in this case, the **your-proxied-app** container).
 
-### SSL Backends
+The containers being proxied must :
 
-If you would like to connect to your backend using HTTPS instead of HTTP, set `VIRTUAL_PROTO=https` on the backend container.
+- [expose](https://docs.docker.com/engine/reference/run/#expose-incoming-ports) the port to be proxied, either by using the `EXPOSE` directive in their `Dockerfile` or by using the `--expose` flag to `docker run` or `docker create`.
+- share at least one Docker network with the nginx-proxy container: by default, if you don't pass the `--net` flag when your nginx-proxy container is created, it will only be attached to the default bridge network. This means that it will not be able to connect to containers on networks other than bridge.
 
-### Default Host
+Note: providing a port number in `VIRTUAL_HOST` isn't suported, please see [virtual ports](https://github.com/nginx-proxy/nginx-proxy/tree/main/docs#virtual-ports) or [custom external HTTP/HTTPS ports](https://github.com/nginx-proxy/nginx-proxy/tree/main/docs#custom-external-httphttps-ports) depending on what you want to achieve.
 
-To set the default host for nginx use the env var `DEFAULT_HOST=foo.bar.com` for example
+### Image variants
 
-    $ docker run -d -p 80:80 -e DEFAULT_HOST=foo.bar.com -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy
+The nginx-proxy images are available in two flavors.
 
+#### Debian based version
 
-### Separate Containers
+This image is based on the nginx:mainline image, itself based on the debian slim image.
 
-nginx-proxy can also be run as two separate containers using the [jwilder/docker-gen](https://index.docker.io/u/jwilder/docker-gen/)
+```console
-image and the official [nginx](https://registry.hub.docker.com/_/nginx/) image.
+docker pull nginxproxy/nginx-proxy:1.6
-
-You may want to do this to prevent having the docker socket bound to a publicly exposed container service.
-
-To run nginx proxy as a separate container you'll need to have [nginx.tmpl](https://github.com/jwilder/nginx-proxy/blob/master/nginx.tmpl) on your host system.
-
-First start nginx with a volume:
-
-
-    $ docker run -d -p 80:80 --name nginx -v /tmp/nginx:/etc/nginx/conf.d -t nginx
-
-Then start the docker-gen container with the shared volume and template:
-
-```
-$ docker run --volumes-from nginx \
-    -v /var/run/docker.sock:/tmp/docker.sock:ro \
-    -v $(pwd):/etc/docker-gen/templates \
-    -t jwilder/docker-gen -notify-sighup nginx -watch -only-exposed /etc/docker-gen/templates/nginx.tmpl /etc/nginx/conf.d/default.conf
 ```
 
-Finally, start your containers with `VIRTUAL_HOST` environment variables.
+#### Alpine based version (`-alpine` suffix)
 
-    $ docker run -e VIRTUAL_HOST=foo.bar.com  ...
+This image is based on the nginx:alpine image.
 
-### SSL Support
+```console
-
+docker pull nginxproxy/nginx-proxy:1.6-alpine
-SSL is supported using single host, wildcard and SNI certificates using naming conventions for
-certificates or optionally specifying a cert name (for SNI) as an environment variable.
-
-To enable SSL:
-
-    $ docker run -d -p 80:80 -p 443:443 -v /path/to/certs:/etc/nginx/certs -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy
-
-The contents of `/path/to/certs` should contain the certificates and private keys for any virtual
-hosts in use.  The certificate and keys should be named after the virtual host with a `.crt` and
-`.key` extension.  For example, a container with `VIRTUAL_HOST=foo.bar.com` should have a
-`foo.bar.com.crt` and `foo.bar.com.key` file in the certs directory.
-
-#### Diffie-Hellman Groups
-
-If you have Diffie-Hellman groups enabled, the files should be named after the virtual host with a
-`dhparam` suffix and `.pem` extension. For example, a container with `VIRTUAL_HOST=foo.bar.com`
-should have a `foo.bar.com.dhparam.pem` file in the certs directory.
-
-#### Wildcard Certificates
-
-Wildcard certificates and keys should be named after the domain name with a `.crt` and `.key` extension.
-For example `VIRTUAL_HOST=foo.bar.com` would use cert name `bar.com.crt` and `bar.com.key`.
-
-#### SNI
-
-If your certificate(s) supports multiple domain names, you can start a container with `CERT_NAME=<name>`
-to identify the certificate to be used.  For example, a certificate for `*.foo.com` and `*.bar.com`
-could be named `shared.crt` and `shared.key`.  A container running with `VIRTUAL_HOST=foo.bar.com`
-and `CERT_NAME=shared` will then use this shared cert.
-
-#### How SSL Support Works
-
-The SSL cipher configuration is based on [mozilla nginx intermediate profile](https://wiki.mozilla.org/Security/Server_Side_TLS#Nginx) which
-should provide compatibility with clients back to Firefox 1, Chrome 1, IE 7, Opera 5, Safari 1,
-Windows XP IE8, Android 2.3, Java 7.  The configuration also enables HSTS, and SSL
-session caches.
-
-The default behavior for the proxy when port 80 and 443 are exposed is as follows:
-
-* If a container has a usable cert, port 80 will redirect to 443 for that container so that HTTPS
-is always preferred when available.
-* If the container does not have a usable cert, a 503 will be returned.
-
-Note that in the latter case, a browser may get an connection error as no certificate is available
-to establish a connection.  A self-signed or generic cert named `default.crt` and `default.key`
-will allow a client browser to make a SSL connection (likely w/ a warning) and subsequently receive
-a 503.
-
-To serve traffic in both SSL and non-SSL modes without redirecting to SSL, you can include the
-environment variable `HTTPS_METHOD=noredirect` (the default is `HTTPS_METHOD=redirect`).  You can also
-disable the non-SSL site entirely with `HTTPS_METHOD=nohttp`. 
-
-### Basic Authentication Support
-
-In order to be able to secure your virtual host, you have to create a file named as its equivalent VIRTUAL_HOST variable on directory
-/etc/nginx/htpasswd/$VIRTUAL_HOST
-
-```
-$ docker run -d -p 80:80 -p 443:443 \
-    -v /path/to/htpasswd:/etc/nginx/htpasswd \
-    -v /path/to/certs:/etc/nginx/certs \
-    -v /var/run/docker.sock:/tmp/docker.sock:ro \
-    jwilder/nginx-proxy
 ```
 
-You'll need apache2-utils on the machine where you plan to create the htpasswd file. Follow these [instructions](http://httpd.apache.org/docs/2.2/programs/htpasswd.html)
+> [!IMPORTANT]
+>
+> #### A note on `latest` and `alpine`:
+>
+> It is not recommended to use the `latest` (`nginxproxy/nginx-proxy`, `nginxproxy/nginx-proxy:latest`) or `alpine` (`nginxproxy/nginx-proxy:alpine`) tag for production setups.
+>
+> [Those tags point](https://hub.docker.com/r/nginxproxy/nginx-proxy/tags) to the latest commit in the `main` branch. They do not carry any promise of stability, and using them will probably put your nginx-proxy setup at risk of experiencing uncontrolled updates to non backward compatible versions (or versions with breaking changes). You should always specify the version you want to use explicitly to ensure your setup doesn't break when the image is updated.
 
-### Custom Nginx Configuration
+### Additional documentation
 
-If you need to configure Nginx beyond what is possible using environment variables, you can provide custom configuration files on either a proxy-wide or per-`VIRTUAL_HOST` basis.
+Please check the [docs section](https://github.com/nginx-proxy/nginx-proxy/tree/main/docs).
 
-#### Replacing default proxy settings
+### Powered by 
 
-If you want to replace the default proxy settings for the nginx container, add a configuration file at `/etc/nginx/proxy.conf`. A file with the default settings would
+[![GoLand logo](https://resources.jetbrains.com/storage/products/company/brand/logos/GoLand_icon.svg)](https://www.jetbrains.com/go/)
-look like this:
+[![PyCharm logo](https://resources.jetbrains.com/storage/products/company/brand/logos/PyCharm_icon.svg)](https://www.jetbrains.com/pycharm/)
-
-```Nginx
-# HTTP 1.1 support
-proxy_http_version 1.1;
-proxy_buffering off;
-proxy_set_header Host $http_host;
-proxy_set_header Upgrade $http_upgrade;
-proxy_set_header Connection $proxy_connection;
-proxy_set_header X-Real-IP $remote_addr;
-proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-proxy_set_header X-Forwarded-Proto $proxy_x_forwarded_proto;
-```
-
-***NOTE***: If you provide this file it will replace the defaults; you may want to check the .tmpl file to make sure you have all of the needed options.
-
-#### Proxy-wide
-
-To add settings on a proxy-wide basis, add your configuration file under `/etc/nginx/conf.d` using a name ending in `.conf`.
-
-This can be done in a derived image by creating the file in a `RUN` command or by `COPY`ing the file into `conf.d`:
-
-```Dockerfile
-FROM jwilder/nginx-proxy
-RUN { \
-      echo 'server_tokens off;'; \
-      echo 'client_max_body_size 100m;'; \
-    } > /etc/nginx/conf.d/my_proxy.conf
-```
-
-Or it can be done by mounting in your custom configuration in your `docker run` command:
-
-    $ docker run -d -p 80:80 -p 443:443 -v /path/to/my_proxy.conf:/etc/nginx/conf.d/my_proxy.conf:ro -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy
-
-#### Per-VIRTUAL_HOST
-
-To add settings on a per-`VIRTUAL_HOST` basis, add your configuration file under `/etc/nginx/vhost.d`. Unlike in the proxy-wide case, which allows multiple config files with any name ending in `.conf`, the per-`VIRTUAL_HOST` file must be named exactly after the `VIRTUAL_HOST`.
-
-In order to allow virtual hosts to be dynamically configured as backends are added and removed, it makes the most sense to mount an external directory as `/etc/nginx/vhost.d` as opposed to using derived images or mounting individual configuration files.
-
-For example, if you have a virtual host named `app.example.com`, you could provide a custom configuration for that host as follows:
-
-    $ docker run -d -p 80:80 -p 443:443 -v /path/to/vhost.d:/etc/nginx/vhost.d:ro -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy
-    $ { echo 'server_tokens off;'; echo 'client_max_body_size 100m;'; } > /path/to/vhost.d/app.example.com
-
-If you are using multiple hostnames for a single container (e.g. `VIRTUAL_HOST=example.com,www.example.com`), the virtual host configuration file must exist for each hostname. If you would like to use the same configuration for multiple virtual host names, you can use a symlink:
-
-    $ { echo 'server_tokens off;'; echo 'client_max_body_size 100m;'; } > /path/to/vhost.d/www.example.com
-    $ ln -s /path/to/vhost.d/www.example.com /path/to/vhost.d/example.com
-
-#### Per-VIRTUAL_HOST default configuration
-
-If you want most of your virtual hosts to use a default single configuration and then override on a few specific ones, add those settings to the `/etc/nginx/vhost.d/default` file. This file
-will be used on any virtual host which does not have a `/etc/nginx/vhost.d/{VIRTUAL_HOST}` file associated with it.
-
-#### Per-VIRTUAL_HOST location configuration
-
-To add settings to the "location" block on a per-`VIRTUAL_HOST` basis, add your configuration file under `/etc/nginx/vhost.d`
-just like the previous section except with the suffix `_location`.
-
-For example, if you have a virtual host named `app.example.com` and you have configured a proxy_cache `my-cache` in another custom file, you could tell it to use a proxy cache as follows:
-
-    $ docker run -d -p 80:80 -p 443:443 -v /path/to/vhost.d:/etc/nginx/vhost.d:ro -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy
-    $ { echo 'proxy_cache my-cache;'; echo 'proxy_cache_valid  200 302  60m;'; echo 'proxy_cache_valid  404 1m;' } > /path/to/vhost.d/app.example.com_location
-
-If you are using multiple hostnames for a single container (e.g. `VIRTUAL_HOST=example.com,www.example.com`), the virtual host configuration file must exist for each hostname. If you would like to use the same configuration for multiple virtual host names, you can use a symlink:
-
-    $ { echo 'proxy_cache my-cache;'; echo 'proxy_cache_valid  200 302  60m;'; echo 'proxy_cache_valid  404 1m;' } > /path/to/vhost.d/app.example.com_location
-    $ ln -s /path/to/vhost.d/www.example.com /path/to/vhost.d/example.com
-
-#### Per-VIRTUAL_HOST location default configuration
-
-If you want most of your virtual hosts to use a default single `location` block configuration and then override on a few specific ones, add those settings to the `/etc/nginx/vhost.d/default_location` file. This file
-will be used on any virtual host which does not have a `/etc/nginx/vhost.d/{VIRTUAL_HOST}` file associated with it.

-Test suite
+Nginx proxy test suite
-==========
+======================
 
-This test suite is implemented on top of the [Bats](https://github.com/sstephenson/bats/blob/master/README.md) test framework.
+Install requirements
+--------------------
 
-It is intended to verify the correct behavior of the Docker image `jwilder/nginx-proxy:bats`.
+You need [Docker Compose v2](https://docs.docker.com/compose/install/linux/), [python 3.9](https://www.python.org/) and [pip](https://pip.pypa.io/en/stable/installation/)  installed. Then run the commands:
 
-Running the test suite
+    pip install -r requirements/python-requirements.txt
-----------------------
 
-Make sure you have Bats installed, then run:
+Prepare the nginx-proxy test image
+----------------------------------
 
-    docker build -t jwilder/nginx-proxy:bats .
+    make build-nginx-proxy-test-debian
-    bats test/
+
+or if you want to test the alpine flavor:
+
+    make build-nginx-proxy-test-alpine
+
+Run the test suite
+------------------
+
+    pytest
+
+need more verbosity ?
+
+    pytest -s
+
+Note: By default this test suite relies on Docker Compose v2 with the command `docker compose`. It still supports Docker Compose v1 via the `DOCKER_COMPOSE` environment variable:
+
+    DOCKER_COMPOSE=docker-compose pytest
+
+Run one single test module
+--------------------------
+
+    pytest test_nominal.py
+
+Run the test suite from a Docker container
+------------------------------------------
+
+If you cannot (or don't want to) install pytest and its requirements on your computer. You can use the nginx-proxy-tester docker image to run the test suite from a Docker container.
+
+    make test-debian
+
+or if you want to test the alpine flavor:
+
+    make test-alpine
+
+Write a test module
+-------------------
+
+This test suite uses [pytest](http://doc.pytest.org/en/latest/). The [conftest.py](conftest.py) file will be automatically loaded by pytest and will provide you with two useful pytest [fixtures](https://docs.pytest.org/en/latest/explanation/fixtures.html): 
+
+- docker_compose
+- nginxproxy
+
+
+### docker_compose fixture
+
+When using the `docker_compose` fixture in a test, pytest will try to start the [Docker Compose](https://docs.docker.com/compose/) services corresponding to the current test module, based on the test module filename.
+
+By default, if your test module file is `test/test_subdir/test_example.py`, then the `docker_compose` fixture will try to load the following files, [merging them](https://docs.docker.com/reference/compose-file/merge/) in this order:
+
+1. `test/compose.base.yml`
+2. `test/test_subdir/compose.base.override.yml` (if it exists)
+3. `test/test_subdir/test_example.yml`
+
+The fixture will run the _docker compose_ command with the `-f` option to load the given compose files. So you can test your docker compose file syntax by running it yourself with:
+
+    docker compose -f test/compose.base.yml -f test/test_subdir/test_example.yml up -d
+
+The first file contains the base configuration of the nginx-proxy container common to most tests:
+
+```yaml
+services:
+  nginx-proxy:
+    image: nginxproxy/nginx-proxy:test
+    container_name: nginx-proxy
+    volumes:
+      - /var/run/docker.sock:/tmp/docker.sock:ro
+    ports:
+      - "80:80"
+      - "443:443"
+```
+
+The second optional file allow you to override this base configuration for all test modules in a subfolder.
+
+The third file contains the services and overrides specific to a given test module.
+
+This automatic merge can be bypassed by using a file named `test_example.base.yml` (instead of `test_example.yml`). When this file exist, it will be the only one used by the test and no merge with other compose files will automatically occur.
+
+The `docker_compose` fixture also set the `PYTEST_MODULE_PATH` environment variable to the absolute path of the current test module directory, so it can be used to mount files or directory relatives to the current test.
+
+In the case you are running pytest from within a docker container, the `docker_compose` fixture will make sure the container running pytest is attached to all docker networks. That way, your test will be able to reach any of them.
+
+In your tests, you can use the `docker_compose` variable to query and command the docker daemon as it provides you with a [client from the docker python module](https://docker-py.readthedocs.io/en/4.4.4/client.html#client-reference).
+
+Also this fixture alters the way the python interpreter resolves domain names to IP addresses in the following ways:
+
+Any domain name containing the substring `nginx-proxy` will resolve to `127.0.0.1` if the tests are executed on a Darwin (macOS) system, otherwise the IP address of the container that was created from the `nginxproxy/nginx-proxy:test` image.
+
+So, in tests, all the following domain names will resolve to either localhost or the nginx-proxy container's IP:
+
+- `nginx-proxy`
+- `nginx-proxy.com`
+- `www.nginx-proxy.com`
+- `www.nginx-proxy.test`
+- `www.nginx-proxy`
+- `whatever.nginx-proxyooooooo`
+- ...
+
+Any domain name ending with `XXX.container.docker` will resolve to `127.0.0.1` if the tests are executed on a Darwin (macOS) system, otherwise the IP address of the container named `XXX`.
+
+So, on a non-Darwin system:
+
+- `web1.container.docker` will resolve to the IP address of the `web1` container
+- `f00.web1.container.docker` will resolve to the IP address of the `web1` container
+- `anything.whatever.web2.container.docker` will resolve to the IP address of the `web2` container
+
+Otherwise, domain names are resoved as usual using your system DNS resolver.
+
+### nginxproxy fixture
+
+The `nginxproxy` fixture will provide you with a replacement for the python [requests](https://pypi.python.org/pypi/requests/) module. This replacement will just repeat up to 30 times a requests if it receives the HTTP error 404 or 502. This error occurs when you try to send queries to nginx-proxy too early after the container creation.
+
+Also this requests replacement is preconfigured to use the Certificate Authority root certificate [certs/ca-root.crt](certs/) to validate https connections.
+
+Furthermore, the nginxproxy methods accept an additional keyword parameter: `ipv6` which forces requests made against containers to use the containers IPv6 address when set to `True`. If IPv6 is not supported by the system or docker, that particular test will be skipped.
+
+    def test_forwards_to_web1_ipv6(docker_compose, nginxproxy):
+        r = nginxproxy.get("http://web1.nginx-proxy.tld/port", ipv6=True)
+        assert r.status_code == 200   
+        assert r.text == "answer from port 81\n"
+
+
+
+### The web docker image
+
+When you run the `make build-webserver` command, you built a [`web`](requirements/README.md) docker image which is convenient for running a small web server in a container. This image can produce containers that listens on multiple ports at the same time.
+
+### Testing TLS
+
+If you need to create server certificates, use the [`certs/create_server_certificate.sh`](certs/) script. Pytest will be able to validate any certificate issued from this script.

+create_server_certificate.sh
+============================
+
+`create_server_certificate.sh` is a script helping with issuing server certificates that can be used to provide TLS on web servers.
+
+It also creates a Certificate Authority (CA) root key and certificate. This CA root certificate can be used to validate the server certificates it generates.
+
+For instance, with _curl_:
+
+    curl --cacert /somewhere/ca-root.crt https://www.example.com/
+
+or with _wget_:
+
+    wget --certificate=/somewhere/ca-root.crt https://www.example.com/
+
+or with the python _requests_ module:
+
+    import requests
+    r = requests.get("https://www.example.com", verify="/somewhere/ca-root.crt")
+
+Usage
+-----
+
+### Simple domain
+
+Create a server certificate for domain `www.example.com`:
+
+    ./create_server_certificate.sh www.example.com
+
+Will produce:
+ - `www.example.com.key`
+ - `www.example.com.crt`
+
+
+### Multiple domains 
+
+Create a server certificate for main domain `www.example.com` and alternative domains `example.com`, `foo.com` and `bar.com`:
+
+    ./create_server_certificate.sh www.example.com foo.com bar.com
+
+Will produce:
+ - `www.example.com.key`
+ - `www.example.com.crt`
+ 
+### Wildcard domain
+
+Create a server certificate for wildcard domain `*.example.com`:
+
+    ./create_server_certificate.sh "*.example.com"
+
+Note that you need to use quotes around the domain string or the shell would expand `*`.
+
+Will produce:
+ - `*.example.com.key`
+ - `*.example.com.crt`
+
+Again, to prevent your shell from expanding `*`, use quotes. i.e.: `cat "*.example.com.crt"`.
+
+Such a server certificate would be valid for domains:
+- `foo.example.com` 
+- `bar.example.com`
+
+but not for domains:
+- `example.com`
+- `foo.bar.example.com`
+
+
+### Wildcard domain on multiple levels
+
+While you can technically create a server certificate for wildcard domain `*.example.com` and alternative name `*.*.example.com`, client implementations generally do not support multiple wildcards in a domain name.
+
+For instance, a python script using urllib3 would fail to validate domain `foo.bar.example.com` presenting a certificate with name `*.*.example.com`. It is advised to stay away from producing such certificates.
+
+If you want to give it a try:
+
+    ./create_server_certificate.sh "*.example.com" "*.*.example.com"
+
+Such a server certificate would be valid for domains:
+- `foo.example.com` 
+- `bar.example.com`
+- `foo.bar.example.com`

+This directory contains resources to build Docker images tests depend on
+
+# Build images
+
+    make build-webserver
+
+
+# python-requirements.txt
+
+If you want to run the test suite from your computer, you need python and a few python modules.
+The _python-requirements.txt_ file describes the python modules required. To install them, use
+pip:
+
+    pip install -r python-requirements.txt
+
+If you don't want to run the test from your computer, you can run the tests from a docker container, see the _pytest.sh_ script.
+
+
+# Images
+
+## web
+
+This container will run one or many webservers, each of them listening on a single port.
+
+Ports are specified using the `WEB_PORTS` environment variable:
+
+    docker run -d -e WEB_PORTS=80 web  # will create a container running one webserver listening on port 80
+    docker run -d -e WEB_PORTS="80 81" web  # will create a container running two webservers, one listening on port 80 and a second one listening on port 81
+
+The webserver answers on two paths:
+
+- `/headers`
+- `/port`
+
+```
+$ docker run -d -e WEB_PORTS=80 -p 80:80 web
+$ curl http://127.0.0.1:80/headers
+Host: 127.0.0.1
+User-Agent: curl/7.47.0
+Accept: */*
+
+$ curl http://127.0.0.1:80/port
+answer from port 80
+
+```
+
+
+## nginx-proxy-tester
+
+This is an optional requirement which is usefull if you cannot (or don't want to) install pytest and its requirements on your computer. In this case, you can use the `nginx-proxy-tester` docker image to run the test suite from a Docker container.
+
+To use this image, it is mandatory to run the container using the `pytest.sh` shell script. The script will build the image and run a container from it with the appropriate volumes and settings.
