Docker build fail

[idenkov]

Hello, I am trying to run the Docker container on Ubuntu 20.04 with Docker version 19.03.12, build 48a66213fe It seems the image can't build because of easy_install error, this is the output:

 ---> Running in 995ce457e1c7
Searching for pip
Best match: pip 9.0.3
Adding pip 9.0.3 to easy-install.pth file
Installing pip script to /usr/lib/python3.6/site-packages
error: [Errno 21] Is a directory: '/usr/lib/python3.6/site-packages/pip'

I manged to make it work with the following Dockerfile, I have not tested the service with playbooks yet, but the /api endpoint seems to work. If you think it is good enough please use it or I can make pull request:

You are removing lot of dependencies from the base os(which is centos7 not ubuntu) in the container. I don't think this will work properly. I think that probably you have any kind of problem with your docker environment like in: https://github.com/drivendataorg/concept-to-clinic/issues/287

Ubuntu is the host, not the base image. I stumbled on that thread when I was google-ing, but that is not the problem.

The changes I made is removing easy_install as it fails because there is already /usr/lib/python3.6/site-packages/pip directory with the base Centos 7 image. Probably installed as dependency with some of the packages. Packages like python36 and python36-dev does not exsit at all in this image repos, which is visible in yum stdout:

The binary python36 seems to be replaced with python3.6 in the image that the Dockerfile builds and the path to pip3 is different, probably the base Centos image got updated. It got python3 installed most likely by a chance as dependency with some of the packages.

Does the image build successfully for you? Because I tried a few times on different distributions, just to be sure and it fails the same way.

The image built successfully for me locally on ubuntu 20.04 using podman instead of docker.

I also forked and rebuilt in a github actions pipeline on a ubi8 (rhel 8 container) rebase Dockerfile.ubi8.

GH Actions pipelines run on ubuntu by default as well (20.04 in this case).

Image is available for testing @ quay.io/containercraft/ansible-runner-service
