Unable to run self hosted docker runner on GKE cluster

Murtaza Lokhandwala_eor6ik

I am trying to run a self hosted runner using Docker on GKE cluster deployment.

 

The following command is migrated to k8s deployment(values are dummy):

docker container run -it -v /data:/data -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker/containers:/var/lib/docker/containers:ro -e ACCOUNT_UUID={87642016-abcd-xyze-b27d-1c58450bace4} -e REPOSITORY_UUID={c0c78c96-e5e7-1234-abcd-c337d17dd794} -e RUNNER_UUID={testinge-55c3-55d1-8fe5-15fbcbc06301} -e RUNTIME_PREREQUISITES_ENABLED=true -e OAUTH_CLIENT_ID=J3X0AgzCqjNLfuqeOGAOATAOVTdE7Zr -e OAUTH_CLIENT_SECRET=ATOABGamRkviXzw12345jehreHHMMc27gMGcQCGfhpOz-FJNbDb80eaRJTqjhKhHOX7Q6A2F0F185C6 -e WORKING_DIRECTORY=/data --name runner-e5e949ea-55c3-55d1-8fe5-15fbcbc06301 docker-public.packages.atlassian.com/sox/atlassian/bitbucket-pipelines-runner

Kindly note, the docker command when ran from a local mac machine it is working fine and able to execute the pipeline fine.

But facing issue only with GKE cluster machine.

Let me know if any more info is required.
