Add support to multi host port binding.

Thank you for this enhancement. Please add test coverage for this new behavior so that it can be merged.

New test case
Added support for recorded fixure in test

[lavie]

Thank you for adding test coverage. I must ask, though, that you use the existing style of fixture in the project using the minimal set of command line switches. As it is, the 6th fixture you've added has over 300 lines of configuration and nearly all of them are irrelevant to the project and the test case it's meant to cover.

[rgiuse]

You typically use a standard fixture style, where a running Docker container is generated to perform tests directly.

In this case, I need to bind two different existing IP addresses of your machine to the same port:

One is the universal localhost address, 127.0.0.1.
The other can be one of your local IP addresses.

Only valid existing addresses can be used.

I need to peek a valid local ip address to make sure the test is consistent.

I ran the tests with my configuration and added a "static" fixture test functionality to handle this.

However, I haven't found other valid solutions.

Do you have any suggestions?

These tests are supposed to be run as part of the CI process using GitHub Actions. I don't run them locally.

It's an interesting challenge. Off the top of my head maybe a custom network can be added in GitHub Actions and then the fixture container could be associated with a specific IP address?

e.g.

- name: Create custom Docker network
  run: docker network create --subnet=10.10.0.0/16 custom-net

- name: Run Docker container with custom network
  run: |
    docker run -d --name my-container --network custom-net --ip 10.10.10.10 my-container

[rgiuse]

I can try, but I'm not sure it will work. From what I understand, you can only bind a container port to an IP address of the Docker host.

I don't think you can use the -p option to map a port directly to a Docker network.

Interesting idea in any case!

[rgiuse]

Creating a docker network on 10.10.0.0/16 you can map a port to 10.10.0.1

@rgiuse I'm not sure what the status of the PR is. Were you able to run the tests by creating a custom network?

[rgiuse]

Yes, I was able to run all the test.

[lavie]

Oh good. If you want to add the changes to GitHub Actions please go ahead, otherwise I'll do it. (when I find time..)

[lavie]

Nice work! 🙏
