Image
Image builds a Docker image and pushes it Docker and OCI compatible registries. This resource enables running Docker builds as part of a Pulumi deployment. Note: We recommend you migrate your images to the more modern [Docker
Build](https://www.pulumi.com/registry/packages/docker-build/) provider to get the best possible support, features, and performance. Note: This resource does not delete tags, locally or remotely, when destroyed.
Image name
The Image resource uses imageName to refer to a fully qualified Docker image name, by the format repository:tag. Note that this does not include any digest information and thus will not cause any updates when passed to dependencies, even when using latest tag. To trigger such updates, e.g. when referencing pushed images in container orchestration and management resources, please use the repoDigest Output instead, which is of the format repository@<algorithm>:<hash> and unique per build/push. As of Docker v4.4, repoDigest is now available for local Images.
Cross-platform builds
The Image resource supports cross-platform builds when the Docker engine has cross-platform support enabled via emulators. The Image resource currently supports providing only a single operating system and architecture in the platform field, e.g.: linux/amd64. To enable this support, you may need to install the emulators in the environment running your Pulumi program. If you are using Linux, you may be using Docker Engine or Docker Desktop for Linux, depending on how you have installed Docker. The FAQ for Docker Desktop for Linux describes the differences and how to select which Docker context is in use.
For local development using Docker Desktop, this is enabled by default.
For systems using Docker Engine, install the QEMU binaries and register them with using the docker image from github.com/tonistiigi/binfmt:
docker run --privileged --rm tonistiigi/binfmt --install allIn a GitHub Actions workflow, the docker/setup-qemu-action can be used instead by adding this step to your workflow file. Example workflow usage:
name: Pulumi
on:
push:
branches:
- master
jobs:
up:
name: Preview
runs-on: ubuntu-latest
steps:
# This is the step added:
- name: Set up QEMU
uses: docker/setup-qemu-action@v2
# The ordinary pulumi/actions workflow:
- uses: actions/checkout@v3
- uses: pulumi/actions@v4
with:
command: preview
