Introduction

The repository is for local testing purposes, it makes it easier to setup a buildkit builder for use with buildx, capable of multi-platform builds.

It also setups up an local Docker registry at islandora.io which you can be used to test generating manifests, registry caching etc.

The repository can be used by isle-buildkit, isle-site-template, sandbox, and others.

If you are looking to use Islandora, please read the official documentation.

Requirements

• Docker 20.10+
• GNU Make 4.3+
• mkcert 1.4+
• pre-commit 2.19+ (Optional)

Note: The version of make that comes with OSX is too old. Please update using brew or another package manager.

Usage

$ make
USAGE:
  make [TARGET]... [ARG=VALUE]...

ARGS:
  BUILDER_NAME                   The name of the builder. (e.g. isle-builder)
  NETWORK_NAME                   The name of the network. (e.g. isle-builder)
  REGISTRY_NAME                  The name of the registry container. (e.g. isle-builder-registry)
  REGISTRY_PORT                  The port to expose for registry access. Access via HTTPS. (e.g. 0, which will randomly assigned an open port)
  REGISTRY_UI_PORT               The port to expose for registry UI. Access via HTTP. (e.g. 0, which will randomly assigned an open port)
  BUILDER_KEEP_STORAGE           When pruning the amount of storage to keep. Set to '0' to remove all. (e.g. 10G)

TARGETS:
  start                          Starts the Docker image registry and creates the builder if it does not exist.
  use                            Switches the default builder to use the one created by the 'start' target.
  port                           Displays the port the Docker image registry is running on.
  stop                           Stops the stops the builder and Docker image registry.
  prune                          Frees up disk space by pruning the builder cache.
  destroy                        Destroys the builder and Docker image registry.
  help                           Displays this help message.

Ports

By default no ports are specified so they are allocated dynamically. Though you can choose a port to have it always be consistent (see Usage).

Regardless, you use the following command to print the URLs at which you can access the registry REST API and a web based UI.

$ make port
  Registry                       https://islandora.io:59963
  UI                             http://islandora.io:32805

Pushing

This makes use of https://islandora.io as the URL for the local Docker image repository. It is setup to redirect all requests to localhost.

Assuming you have use the following command to set the default builder to the one created by this repository:

make use

To push to this local repository you must use the name as the image tag like so:

docker buildx build \
  --push \
  --platform linux/arm64,linux/amd64 \
  --tag islandora.io/some-image:latest .

Or if using a bake you should check which variable to override (typically REPOSITORY):

REPOSITORY=islandora.io docker buildx bake --push .

Note that this can be used with docker-compose.yml and docker-bake.hcl files.
