Dockerfile for pipelines?

[ktomk]

Is there a Dockerfile with the pipelines command and PHP already installed?

No, or none that I know about.

have you given any thought to whether this is possible?

Yes, I did. The Dockerfile itself is less the problem, pipelines need to be aware that it is dockerized.

This is merely meta. Pipelines can already be run within Docker, that is the "PIP - Pipelines Inside Pipelines" feature.

It then works very similar as you have outlined.

However you would need to have Docker as a dependency. And that you already have. And then pipelines only needs some PHP version with little requirements. So it should be more straight forward to just install that (take any PHP 5.3.3 - PHP 8.1*) and execute the pipelines.phar file.

Which operating system are you using?

@phitoduck I quickly wrapped one docker image up, so there is something to play:

$ docker run --rm ktomk/pipelines:pipelines                          
pipelines version 0.0.57+5-g712771b+dirty

The default working directory is /app you can use to mount stuff in:

$ docker run --rm -it --entrypoint /bin/pwd ktomk/pipelines:pipelines
/app

to hint pipelines inside pipelines (here docker) the path to the original project directory, there is the PIPELINES_PROJECT_PATH (see README.md for a bit more description) - it is used so that pipelines can - when it detects it runs inside docker (might need more ENV parameters) to mount from host in case the --deploy mount option is in use (but the current container has copy).

sorry for the rough description, merely the quick hint that there are some environment variables if set, it could already run with this image.

I'll add lib/container/pipelines.sh later and link it here, it is the build script for the container.

@phitoduck please find an experimental branch docker-pipelines to kick around with. feel free for any kind of feedback and questions. I'll think a bit about what is needed so that pipelines becomes aware running inside a container without a pipeline is already active.

there will be a couple of rough edges, feel free to name anything you run over.

@phitoduck if you'd like to contribute a Dockerfile for this I'm open to it. For the moment I'd keep this on a temporary branch and will rebase it occasionally.

Wow, sorry for totally dropping off. Thanks for looking into this. It may be another while before I can look at this, but I think my team at work would really like this since it would make it easier to reproduce our exact pipeline locally.
