Describe the bug

After upgrading argo-cd from version v2.3.5 to v.2.4.3 the argo-repo-server stopped working with the logs:

argocd-repo-server time="2022-06-28T16:18:42Z" level=info msg="Generating self-signed gRPC TLS certificate for this session"                                                     │
│ argocd-repo-server time="2022-06-28T16:18:42Z" level=info msg="Initializing GnuPG keyring at /app/config/gpg/keys"                                                               │

This leads to Argo CD UI showing error:

rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp 10.3.43.220:8081: connect: connection refused"

To Reproduce

For me it was just the upgrade.

Expected behavior

argo-repo-server starts up without errors.

Just in case it helps anyone in the future. We were running into this issue on only a couple of nodes where the repo server was being deployed. I saw this https://github.com/argoproj/argo-cd/issues/9888#issuecomment-1383684675 which hinted at a Docker version discrepancy. After upgrading Docker to latest version things started to work without any workarounds.

docker://20.10.17 was failing, docker://20.10.18 and higher is working.

@mohahmed13: Thanks for the info! I will also document my case for the community, note the Docker version details:

My case

Deploying "official" Argo CD Helm chart v6.7.2, which uses Argo CD v2.10.3, to on-prem RKE1 (Rancher Kubernetes Engine) based Kubernetes clusters.

❌ Cluster/node setup not working out-of-the-box

Version: v1.24.17
OS: Ubuntu 20.04.2 LTS
Container Runtime:  Docker 20.10.7

Needs the seccompProfile: type: Unconfined fix described above to work, so that the Argo CD repo server pods stop keeping crashing.

✅ Cluster/node setup working out-of-the-box

Version: v1.24.17
OS: Ubuntu 20.04.4 LTS
