Class Method Details

.process(env) ⇒ Object

Convert an env hash into a Kubernetes env array.

String/numeric values become plain env vars:

"FOO" => "bar"  =>  { name: "FOO", value: "bar" }

ExternalSecret::TemplateRef values become secretKeyRef env vars and register the template entry on the ExternalSecret:

"FOO" => secret.template("{{ .bar }}")
  =>  { name: "FOO", valueFrom: { secretKeyRef: { name: "secret-name", key: "FOO" } } }

Secret::KeyRef values reference an existing secret’s key directly (the same Secret.new(name:).key(…) form used by volume_mounts):

"FOO" => Secret.new(name: "creds").key("bar")
  =>  { name: "FOO", valueFrom: { secretKeyRef: { name: "creds", key: "bar" } } }
