action-runner has crashed loop with latest version.

[h-r-k-matsumoto]

Describe the bug
Suddenly runner pod has crashed loop after 2021-08-11.
I think summerwind/actions-runner:latest is not built correctly.

Checks

• My actions-runner-controller version (v0.x.y) does support the feature
• I'm using an unreleased version of the controller I built from HEAD of the default branch

To Reproduce

First o all , summerwind/actions-runner:latest cannot be started.

$ docker images |findstr  summerwind/actions-runner
summerwind/actions-runner                                                     latest         42c0cefce236   3 hours ago     788MB
$ docker run -it --rm summerwind/actions-runner:latest
standard_init_linux.go:228: exec user process caused: exec format error
$

I think dump-init doesnot install correctly.

$ docker run -it --rm --entrypoint '' summerwind/actions-runner:latest /bin/sh
$ cat  /usr/local/bin/dumb-init
Not Found$

Expected behavior
It can be started normally.

Screenshots
Nothing.

Environment (please complete the following information):

• Controller Version: 0.18.2
• Deployment Method: Kustomize

Additional context
Nothing

There is the code below.
https://github.com/actions-runner-controller/actions-runner-controller/blob/master/runner/Dockerfile#L51

    && curl -L -o /usr/local/bin/dumb-init https://github.com/Yelp/dumb-init/releases/download/v${DUMB_INIT_VERSION}/dumb-init_${DUMB_INIT_VERSION}_${ARCH} \

This is run as follows:

  && curl -L -o /usr/local/bin/dumb-init  https://github.com/Yelp/dumb-init/releases/download/v1.2.5/dumb-init_1.2.5_amd64

However dumb-init_1.2.5_amd64 file is not exists in Yelp/dumb-init/releases/tag/v1.2.5

[h-r-k-matsumoto]

A Condition with downloading dumb-init is wrong.
https://github.com/Yelp/dumb-init/releases/tag/v1.2.3

x86_64 (previously amd64)
aarch64 (previously arm64)
ppc64le (previously ppc64el)

if amd64, $ARCH should be set x86_64 .

I reverted back to an older image, e.g.

# runnerdeployment.yaml
apiVersion: actions.summerwind.dev/v1alpha1
kind: RunnerDeployment
metadata:
  name: serviceplatform
  namespace: runners
spec:
  replicas: 1
  template:
    spec:
      organization: redacted
      image: summerwind/actions-runner:v2.279.0-ubuntu-20.04-743e6d6

You can find a full list of images on docker hub

This was in response to my question on a workaround fix. I had to delete it as I accidentally posted it from one of my orgs github account. Thanks!

I would suggest adding the sha256sum download as part of the image build and match it against the downloaded file.
It's possible the curl resulted in a download of a 404 or 500 page, and we wouldn't know until trying to run the dumb-init

I've confirmed that this issue was solved with #723 , so close it.
Thank you for your cooperation.
