Cluster bootstrap


FLUX_GIT_USERNAME=my-git-username
FLUX_GIT_EMAIL=my-git-email@example.com
flux bootstrap git \
  --author-email=$FLUX_GIT_EMAIL \
  --url=ssh://git@github.com/$FLUX_GIT_USERNAME/gitops-istio \
  --branch=main \
  --path=clusters/my-cluster

At bootstrap, Flux generates an SSH key and prints the public key. In order to sync your cluster state with git you need to copy the public key and create a deploy key with write access on your GitHub repository. On GitHub go to Settings > Deploy keys click on Add deploy key, check Allow write access, paste the Flux public key and click Add key.
