Set up job always fails when running self-hosted runners using OCI images

💬 Feature/Topic Area

Actions Runner

Discussion Details

Using ghcr.io/actions/actions-runner:2.337.0

The request status code is 200, and I don't think it's a network issue.

I don't know where this problem is coming from, because just 12 hours ago, it was still able to run workflow tasks normally, until today when he updated the certificate.

reachability is fine. the runner process is choking on TLS trust/time, not “can’t talk to github”.

that’s the catch - Set up job downloads actions with the runner (.NET), not with node. node/curl can succeed while the job setup path still fails.

do this first on the same OCI container that runs jobs:

date -u
# if this is behind "now", fix NTP / host clock first. a cert that starts at 00:00 GMT today will fail verification if the box is still on yesterday.

curl -fsS -o /dev/null -w '%{http_code}\n' \
  https://codeload.github.com/ruby/setup-ruby/tar.gz/95ef2b042f9d7a56d8268cba8559e2842e2ad01b

# exercise the same stack the runner uses (if pwsh is there):
pwsh -NoProfile -Command \
  "try { (Invoke-WebRequest -Uri 'https://codeload.github.com').StatusCode } catch { $_.Exception.Message; if ($_.Exception.InnerException) { $_.Exception.InnerException.Message } }"

then refresh the image CA store and bounce the runner:

# inside the runner image (debian/ubuntu based actions-runner)
sudo apt-get update
sudo apt-get install --reinstall -y ca-certificates
sudo update-ca-certificates

# and pull a fresh tag rather than a days-old local layer
docker pull ghcr.io/actions/actions-runner:2.337.0
# recreate the container / pod so it actually boots that layer

if you’re on ARC, rebuild/roll the runner pods after the pull so they don’t keep an old rootfs.

if that still fails

• paste the inner exception from the pwsh/Invoke-WebRequest failure (or turn runner diagnostic logging up) - the Set up job log only shows the outer SSL message
• as a last resort on Linux, point the runner at an explicit bundle before start: SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt (runner reads CA like OpenSSL/.NET on Linux - see https://github.com/actions/runner/blob/main/docs/checks/sslcert.md)

so: not “OCI can’t network”. it’s TLS trust/clock on the runner download path right after github’s *.github.com cert rolled today.

Before I had a chance to use your method, it returned to normal during an accidental retry.
