How to fix cp: cannot stat '/actions-runner/_diag': No such file or directory cp: cannot stat '/actions-runner/svc.sh': No such file or directory

[sustainjane98]

After a few hours of work the runner crashed and now it shows this message, I don't understand please help:

Runner reusage is enabled
Copying previous data
The runner has already been configured
Reusage is enabled. Storing data to /runner/data
cp: cannot stat '/actions-runner/_diag': No such file or directory
cp: cannot stat '/actions-runner/svc.sh': No such file or directory

This is my docker-compose:

services:
  worker:
    environment:
      ACCESS_TOKEN: valid_token
      CONFIGURED_ACTIONS_RUNNER_FILES_DIR: /runner/data
      LABELS: linux,x64
      REPO_URL: https://github.com/sustainjane98/bots
      RUNNER_NAME: sustainjane-runner
      RUNNER_SCOPE: repo
      RUNNER_WORKDIR: /tmp/runner/work
    image: myoung34/github-runner:latest
    security_opt:
      - label:disable
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /mnt/storage-1/apps/github-runner/data:/runner/data
      - /tmp/runner:/tmp/runner

A hint is that the runner was registered once in github, but it isn't there anymore in the ui, so I guess it got removed correctly but not sure.

OS: truenas ElectricEel-24.10.2

@sustainjane98 This was a really weird one. thanks for bringing it

I think the culprit is that deregistering a reusable runner puts it in a weird state.
This seems definitely like an actions issue upstream, you can find quite a few issues here and here and more if you search there.

Scroll past the TL;DR for more info.

TL;DR add env var DISABLE_AUTOMATIC_DEREGISTRATION to prevent this.

The longer: I Have no hecking clue what's going on

I replicated it with this yaml:

services:
  worker:
    environment:
      ACCESS_TOKEN: redact
      CONFIGURED_ACTIONS_RUNNER_FILES_DIR: /runner/data
      LABELS: linux,x64
      REPO_URL: https://github.com/octokode/test1
      RUNNER_NAME: sustainjane-runner-1
      RUNNER_SCOPE: repo
      RUNNER_WORKDIR: /tmp/runner/work
    image: myoung34/github-runner:latest
    security_opt:
      - label:disable
    volumes:
      - /tmp/github-runner/data:/runner/data
      - /tmp/runner:/tmp/runner

then did docker compose up, then docker compose down then docker compose up after the runner cleared

I can fix this locally only by doing this with colima (I dont have docker locally): colima stop; colima start --network-address --runtime containerd

In proper docker im unsure, maybe some docker system prune -a after clearing the data

Here's me fixing it locally. after this Im able to get it to work as expected repeatedly by using DISABLE_AUTOMATIC_DEREGISTRATION

Im going to work through a PR to resolve this by enforcing that env var with reusable runs
