Nginx proxy test suite
|
|
======================
|
|
|
|
Install requirements
|
|
--------------------
|
|
|
|
You need [python 2.7](https://www.python.org/) and [pip](https://pip.pypa.io/en/stable/installing/) installed. Then run the commands:
|
|
|
|
requirements/build.sh
|
|
pip install -r requirements/python-requirements.txt
|
|
|
|
If you can't install those requirements on your computer, you can alternatively use the _pytest.sh_ script which will run the tests from a Docker container which has those requirements.
|
|
|
|
|
|
Prepare the nginx-proxy test image
|
|
----------------------------------
|
|
|
|
docker build -t jwilder/nginx-proxy:test ..
|
|
|
|
or if you want to test the alpine flavor:
|
|
|
|
docker build -t jwilder/nginx-proxy:test -f Dockerfile.alpine ..
|
|
|
|
make sure to tag that test image exactly `jwilder/nginx-proxy:test` or the test suite won't work.
|
|
|
|
|
|
Run the test suite
|
|
------------------
|
|
|
|
pytest
|
|
|
|
need more verbosity ?
|
|
|
|
pytest -s
|
|
|
|
|
|
Run one single test module
|
|
--------------------------
|
|
|
|
pytest test_nominal.py
|
|
|
|
|
|
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](http://doc.pytest.org/en/latest/fixture.html#fixture):
|
|
|
|
- docker_compose
|
|
- nginxproxy
|
|
|
|
|
|
### docker_compose fixture
|
|
|
|
When using the `docker_compose` fixture in a test, pytest will try to find a yml file named after your test module filename. For instance, if your test module is `test_example.py`, then the `docker_compose` fixture will try to load a `test_example.yml` [docker compose file](https://docs.docker.com/compose/compose-file/).
|
|
|
|
Once the docker compose file found, the fixture will remove all containers, run `docker-compose up`, and finally your test will be executed.
|
|
|
|
The fixture will run the _docker-compose_ command with the `-f` option to load the given compose file. So you can test your docker compose file syntax by running it yourself with:
|
|
|
|
docker-compose -f test_example.yml up -d
|
|
|
|
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/2.0.2/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 the IP address of the container that was created from the `jwilder/nginx-proxy:test` image. So all the following domain names will resolve to the nginx-proxy container in tests:
|
|
- `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 the IP address of the XXX container.
|
|
- `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 ran the `requirements/build.sh` script earlier, 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. |
