Overview ¶
Package images centralises the policy for selecting Docker image tags in embedded Kubernetes manifests.
The problem this solves: when the obol binary is upgraded, the K8s Deployments it creates must trigger a rolling update so old pods are replaced with ones running the new image. With ":latest" tags the embedded manifest is byte-identical across binary versions, so kubectl apply reports "unchanged" and stale pods keep serving the old image forever.
The fix: production binaries are built with version.GitCommit injected via ldflags, and CI publishes images tagged with the same short commit SHA. Resolve uses that SHA so upgrading the binary changes the image:tag in every manifest, which is what triggers K8s to roll the pod.
Dev mode (OBOL_DEVELOPMENT=true), unset/unknown GitCommit, and dirty repos fall back to ":latest" — that path matches the buildAndImportLocalImages flow that imports freshly-built images into k3d as ":latest".

Functions ¶
func Resolve ¶
Resolve returns the fully-qualified image reference for an image whose repository part is `repo` (e.g. "ghcr.io/obolnetwork/demo-server").
images.Resolve("ghcr.io/obolnetwork/demo-server")
// → "ghcr.io/obolnetwork/demo-server:abc1234" (production)
// → "ghcr.io/obolnetwork/demo-server:latest" (dev / unknown commit)
