Kind with a local registry

Based on https://github.com/tilt-dev/kind-local

When developing locally, you want to push images to the cluster as fast as possible.

Pushing to an in-cluster image registry skips a lot of overhead:

• Unlike with a remote registry, the image stays local to your machine, with no network traffic

• Unlike with kind load, docker will skip pushing any layers that already exist in the registry

This makes it a great solution for iterative local development. But setting it up is awkward and fiddly.

How to

Kind must be installed

1. Create a cluster with kind-with-registry.sh

   It creates the registry at port 5000

   $ k8s/kind-with-registry.sh

   • Teardown the cluster with teardown-kind-with-registry.sh

     $ k8s/teardown-kind-with-registry.sh

2. Push an image

   # Build image
   $ docker build -f ./docker/Dockerfile.gateway -t gateway .
   # Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE
   $ docker tag gateway localhost:5000/gateway
   # Push the image to the local registry
   $ docker push localhost:5000/gateway

3. Use the image

   You can now use the image name localhost:5000/gateway in any resources you deploy to the Kind cluster.

Docker

Build Docker images

$ ./docker/docker.sh

Arguments

• --push=<true|false>

  Default: false

  Push the images to the registry.

• --push-prefix=

  Default: localhost:5000/

  Prefix for registry images.
