Unable to get registration_token 404 Error (GET request instead of POST)

[roshitho]

I am setting up arcs on Azure AKS for self-hosted runners to be used from github enterprise server (on-prem) .

I have performed the steps as in https://github.com/actions/actions-runner-controller/blob/master/docs/quickstart.md

But the pods do not come up. The controller log shows the following error- failed to create registration token: GET https://gitesurl/api/v3/repos/myorg/myrepo/actions/runners/registration-token: 404 Not Found

I am expecting a POST request here not GET. Is the issue because of that?

Following steps I have had to do additionally to make it work with github enterprise.

1. Add additional volume and volume mount for certificate (--set=additionalVolumeMounts[0].name=gh-crt ....)
2. Add host alias in deployment.
3. Set env for GITHUB_ENTERPRISE_URL=https://enterpriseurl
4. set env for certificate SSL_CERT_DIR=/usr/share/ca-certificates
5. Add additional params for step 1 (helm upgrade --install --namespace actions-runner-system --create-namespace ...)
   . --set=githubURL="https://githubesurl/api/v3"\
   --set=githubUploadURL="https://githubesurl/api/uploads"\
   --set=runnerGithubURL="https://githubesurl"\

Does any of it affect the call? I am assuming GET will not be implemented (a 405 error/unimplemented error) .

Any pointers would be very helpful.

Thanks
