checkout does not work on centos6 job container

[chipitsine]

I'm trying to run workflows on custom docker images.

here's my workflow:

https://github.com/chipitsine/haproxy/blob/master/.github/workflows/centos-6.yml

here's error

looks like node.js 12 requires glibc 2.17+ https://github.com/nodejs/node/blob/v12.x/BUILDING.md#platform-list

centos 6 only has glibc 2.12 https://centos.pkgs.org/6/centos-x86_64/glibc-2.12-1.212.el6.x86_64.rpm.html

we needs to use node.js 10 for centos 6 since node 10 only requires glibc 2.12
or we just doc we don't support centos 6 for javascript actions?

@bryanmacfarlane, @chrispat thoughts?

i ran into issues with out of memory problems using node 10 when launching external processes. I burned many hours trying to reduce memory before exec, but nothing worked and amount of memory process was using seemed small anyway (couple megabytes iirc) so limitation didnt make sense. I hit the issue in the setup-node repo running unit tests, and eventually switched to node 12 since that is what runner uses anyway.

I've run into this problem too.
Node.js v12.16.0 and greater can actually be compiled on CentOS 6; you need to use devtoolset-6 and set LDFLAGS=-lrt when compiling as mentioned here.

To compile you will also need to install Python 2.7 since CentOS 6 still uses 2.6.

I actually created a Docker image that builds it thinking the runner would detect it but I later noticed that's hardcoded.

[bryanmacfarlane]

The runner carries a version of node12 as a script runtime for javascript actions. We can't be variable to what's on the end users machine. Node in the path is for running user's steps / code.

[bryanmacfarlane]

we also currently don't support redhat6 and centos6. AZP had to do another build of the runner and so far in actions, we've refrained from that. Increasing platform support is tracked in another issue.

[bryanmacfarlane]

It's feature work to support redhat / centos 6

[silvanocerza]

@chipitsine Try to use actions/checkout@v1, I've just tried it on CentOS 6 and it works since it doesn't require Node. actions/upload-artifact and actions/download-artifact also work.

Those actions specify runs.plugin on their action.yml and they are run directly by the runner and don't need other dependencies.

It's not the best solution but for now it will do I guess.
