kbld

kbld

kbld can

• resolve images to their immutable image references (digests)
• optionally build Docker images (by delegating to tools such as Docker)
• export set of images as a single tarball, and import into a different registry
  • maintaining exactly same digests, hence guaranteeing exactly same content

Example of using ytt + kbld + kapp to deploy an application:

ytt template -R -f kubernetes-manifests/ | kbld -f- | kapp -y deploy -a app1 -f-
