# Docker Build Hooks
|
|
|
|
The files in this folder are used by Docker Cloud to automate image builds.
|
|
|
|
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.
|
|
`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`.
|
|
|
|
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.
|
|
