+Variable references $(VAR_NAME) are expanded using the container's environment. If a variable
+cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced
+to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will
+produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless
+of whether the variable exists or not. Cannot be updated.

+StartupProbe indicates that the Pod has successfully initialized.
+If specified, no other probes are executed until this completes successfully.
+If this probe fails, the Pod will be restarted, just as if the livenessProbe failed.
