Document the minimum dependencies necessary to use this action with custom containers

[kevinburke1]

It would be nice to know the minimum amount of software necessary to run this with a custom container. For example, this project requires git at at least v2.18.

I'm currently trying to debug this failure:

/usr/bin/docker exec  186a95cc5746a0d66133af0ae7ec9e161d903825e4c12bdf02f1a2fcede1fe14 sh -c "cat /etc/*release | grep ^ID"
Running JavaScript Action with default external tool: node12
OCI runtime exec failed: exec failed: container_linux.go:346: starting container process caused "no such file or directory": unknown

I suspect this means I need to add Node.js to the container image but I'm not sure.

@kevinburkemeter thanks. We're going to fallback to downloading the repo using the REST API if git isnt in the PATH.

will be fixed by pr actions/checkout#104

@kevinburkemeter we automatically inject node into the container as that is a runtime concern you should not have to deal with.

I'm still seeing this with actions/checkout@v2 and also master.
I'm running on self-hosted runner, with a custom container:

build:
    runs-on: self-hosted
    container: maven:3-jdk-11

Transferring to actions/runner

This looks related to minimum dependencies to run any javascript action.

Related to #334 ?

is node a binary executable? What if my container is i386 or arm?

still seeing the issue:

Hi @igagis! Is this issue still a problem on a newer runner version?

[igagis]

@nikola-jokic I don't know, I'm not using official runner for self-hosted machines anymore, I'm using https://github.com/ChristopherHX/github-act-runner and also I don't use javascript-based actions in my pipelines anymore. So, I cannot check, sorry.

[nikola-jokic]

Since this issue is related to actions/checkout, but we use this issue board to track issues with the runner, I am closing this issue.
