usage_description="
|
|
Creates Kubernetes sealed secrets from all Kubernetes secrets in the current or given namespace
|
|
|
|
Iterates all non-service-account-token secrets, and for each one:
|
|
|
|
- generates sealed secret yaml
|
|
- annotates existing secret to be able to be managed by sealed secrets
|
|
- creates sealed secret in the same namespace
|
|
|
|
Useful to migrate existing secrets to sealed secrets which are safe to commit to Git
|
|
|
|
Use kubectl_secrets_download.sh to take a backup of secrets first
|
|
|
|
XXX: you should probably omit committing secrets generated by Cert Manager (eg. *-tls)
|
|
|
|
|
|
Requires kubectl and kubeseal to both be in the \$PATH and configured
