Docker Build Hooks

The files in this folder are used by Docker Cloud to automate image builds. Do not edit these files.

If you want to build, maintain and push multi-architecture Docker images, you may follow the example provided here. All of the hooks are generic, and will work with any build. Two environment variables must be passed in from Docker Cloud config.

1. BUILDS must be set to the builds you're trying to perform. This repo is currently set to:
   • linux:armhf:arm: linux:arm64:arm64:armv8 linux:amd64:amd64: linux:i386:386:
   • The format is os:name:arch:variant.
   • os and name are passed into the Dockerfile.
   • os, arch and variant are passed into docker manifest annotate.
   • This does not yet work with an OS other than linux.
2. Set DOCKER_CLI_EXPERIMENTAL to enabled. Not optional.

Keep the build simple; see screenshot. This only supports one build tag, but it creates many more.

The fancy source tag is /^v((\d+\.\d+)(?:\.\d+)?)$/ and it allows you to capture the minor version without patch-level in {\2}. I no longer use {\2} in my build. See how it works here.
