Change Overview
This PR introduces the ephemeral package meant to handle registering and applying ephemeral pod specific fields.
The first use-case was to introduce FIPS related environment variables that need to be set on all ephemeral pods to ensure the crypto backend (OpenSSL in this case) is started with the FIPS provider enabled and fails otherwise.
The registration mechanism is made to be generic by using an
Applierinterface which is used to register different ways of applying changes to a*kube.PodOptionsor a*corev1.Container.For now convenience functions related to registering environment variable Applier's are added. The conditional environment variable helper is the OSEnvVar function which looks to see if the environment variable is set on the OS and applies it to the ephemeral pod if so. This usage is the main need for setting the FIPS environment variables since they're already present on the parent pod launching the ephemeral pods.
All places that used the
kube.PodOptionsandcorev1.Containertypes have the ephemeral.Options.Apply() function added which adds all registered Appliers (only environment variables at this point) to the pod.Pull request type
