Export image to Docker
You may want your build result to be available in the Docker client through docker images
to be able to use it
in another step of your workflow:
name: ci
on:
push:
branches:
- 'main'
jobs:
docker:
runs-on: ubuntu-latest
steps:
-
name: Checkout
uses: actions/checkout@v3
-
name: Set up Docker Buildx
uses: docker/setup-buildx-action@v2
-
name: Build
uses: docker/build-push-action@v3
with:
context: .
load: true
tags: myimage:latest
-
name: Inspect
run: |
docker image inspect myimage:latest
Usage of the built image in other build steps
By default, docker/setup-buildx-action@v2
uses docker-container
as a build driver, so the docker images are not available in the builder container.
To use them, you may use build contexts:
name: ci
on:
push:
branches:
- 'main'
jobs:
docker:
runs-on: ubuntu-latest
steps:
-
name: Checkout
uses: actions/checkout@v3
-
name: Set up Docker Buildx
uses: docker/setup-buildx-action@v2
-
name: Build base image
uses: docker/build-push-action@v3
with:
context: base
load: true
tags: my-base-image:latest
-
name: Build image from my-base-image:latest
uses: docker/build-push-action@v3
with:
context: .
build-contexts: |
base-image=docker-image://my-base-image:latest
tags: myimage:latest
Where base-image
is the name of the base image (or stage name if specified) in your Dockerfile:
FROM base-image
Bake alternative
You may also want to use bake and build the base image and the target image in one build step:
# docker-bake.hcl
target "base" {
dockerfile = "baseapp.Dockerfile"
}
target "app" {
contexts = {
baseapp = "target:base"
}
}
-
name: Build
uses: docker/bake-action@v2
with:
target: app
