How to fix Flux source not ready in Kubernetes
KubernetesINTERMEDIATEMEDIUM
A Flux GitRepository or HelmRepository source cannot be reached or authenticated. This prevents Flux from syncing applications. Verify source connectivity, credentials, and repository configuration.
What this error means
Flux CD uses Source objects (GitRepository, HelmRepository, etc.) to define where to fetch manifests and charts. When a source cannot be accessed, cloned, or authenticated, Flux marks it as NotReady and cannot proceed with reconciliation. This blocks all dependent Kustomizations and HelmReleases.
Typical symptoms
GitRepository shows "NotReady" status in Flux
Flux logs show authentication or connection errors
HelmRepository cannot be reached
Kustomization shows "GitRepository not ready"
kubectl get gitrepository shows conditions errors
Flux reconciliation fails silently
Source sync events show connection timeouts
Common causes
Git repository URL is incorrect or unreachable
SSH key authentication missing or invalid
GitHub token expired or has insufficient permissions
