Use: "gitea",
Short: "Bootstrap toolkit components in a Gitea repository",
Long: `The bootstrap gitea command creates the Gitea repository if it doesn't exists and
commits the toolkit components manifests to the main branch.
Then it configures the target cluster to synchronize with the repository.
If the toolkit components are present on the cluster,
the bootstrap command will perform an upgrade if needed.`,
Example: ` # Create a Gitea personal access token and export it as an env var
export GITEA_TOKEN=<my-token>
# Run bootstrap for a private repository owned by a Gitea organization
flux bootstrap gitea --owner=<organization> --repository=<repository name>
# Run bootstrap for a private repository and assign organization teams to it
flux bootstrap gitea --owner=<organization> --repository=<repository name> --team=<team1 slug> --team=<team2 slug>
# Run bootstrap for a private repository and assign organization teams with their access level(e.g maintain, admin) to it
flux bootstrap gitea --owner=<organization> --repository=<repository name> --team=<team1 slug>:<access-level>
# Run bootstrap for a repository path
flux bootstrap gitea --owner=<organization> --repository=<repository name> --path=dev-cluster
# Run bootstrap for a public repository on a personal account
flux bootstrap gitea --owner=<user> --repository=<repository name> --private=false --personal=true
# Run bootstrap for a private repository hosted on Gitea Enterprise using SSH auth
flux bootstrap gitea --owner=<organization> --repository=<repository name> --hostname=<domain> --ssh-hostname=<domain>
# Run bootstrap for a private repository hosted on Gitea Enterprise using HTTPS auth
flux bootstrap gitea --owner=<organization> --repository=<repository name> --hostname=<domain> --token-auth
# Run bootstrap for an existing repository with a branch named main
