|
## Registry cache
|
|
|
|
You can import/export cache from a cache manifest or (special) image configuration on the registry.
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches:
|
|
- 'master'
|
|
|
|
jobs:
|
|
docker:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Checkout
|
|
uses: actions/checkout@v2
|
|
-
|
|
name: Set up Docker Buildx
|
|
uses: docker/setup-buildx-action@v1
|
|
-
|
|
name: Login to DockerHub
|
|
uses: docker/login-action@v1
|
|
with:
|
|
username: ${{ secrets.DOCKERHUB_USERNAME }}
|
|
password: ${{ secrets.DOCKERHUB_TOKEN }}
|
|
-
|
|
name: Build and push
|
|
uses: docker/build-push-action@v2
|
|
with:
|
|
context: .
|
|
push: true
|
|
tags: user/app:latest
|
|
cache-from: type=registry,ref=user/app:latest
|
|
cache-to: type=inline
|
|
```
|
|
|
|
## GitHub cache
|
|
|
|
> :warning: At the moment caches are copied over the existing cache so it [keeps growing](https://github.com/docker/build-push-action/issues/252).
|
|
> The `Move cache` step is used as a temporary fix (see https://github.com/moby/buildkit/issues/1896).
|
|
|
|
> :rocket: There is a new cache backend using GitHub cache being developed that will lighten your workflow.
|
|
> More info: https://github.com/docker/buildx/pull/535
|
|
|
|
You can leverage [GitHub cache](https://docs.github.com/en/actions/configuring-and-managing-workflows/caching-dependencies-to-speed-up-workflows)
|
|
