pub fn effective_pull_policy(
    image: &Reference,
    spec_policy: PullPolicy,
) -> PullPolicy
Expand description

Resolve the effective pull policy for a deploy/scale operation.

The serde default for pull_policy is IfNotPresent (preserved for backwards compatibility). When the user has not opted out (i.e. the policy is the default IfNotPresent) AND the image tag is :latest or unspecified, we auto-upgrade to Newer so freshly-pushed :latest images get picked up on redeploy. Users who explicitly want immutable behaviour on a :latest tag can set pull_policy: never.
