argocd-setup-ssh-known-hosts-configmap.yaml

#
# If you are connecting repositories via SSH, ArgoCD will need to know the SSH known hosts public key of the repository servers.
# This ConfigMap contains a single key/value pair, with ssh_known_hosts as the key and the actual public keys of the SSH servers as data.
# The public key(s) of each single repository server ArgoCD will connect via SSH must be configured, otherwise the connections to the repository will fail. There is no fallback.
# The public key can be obtained from an existing ~/.ssh/known_hosts or using a CLI utility as follows: 'ssh-keyscan github.com'
