Multi-platform Images

The following guides describe how to Build the Images for Multiple Platforms. This is especially useful should you need to use the Image ond AMD64 and/or ARM64 architectures.

The examples here use a full registry details in the path as an example because the build tool currently has a limitation where it can't build multi-platform Images locally. The registry paths can be modified to suit your needs. They show how to build images for both GitLab and GitHub Container Registries.

Use the buildx tool to build the images

Activate the use of buildx

docker buildx create --use

Build the All DevOps Image

docker buildx build --platform $PLATFORMS --target all-devops --pull \
-t $ALL_DEVOPS_IMAGE_NAME\:latest \
-t $ALL_DEVOPS_IMAGE_NAME\:$DEVOPS_IMAGE_VERSION \
-t $ALL_DEVOPS_IMAGE_NAME\:$TIMESTAMP \
-t $GHCR_ALL_DEVOPS_IMAGE_NAME\:latest \
-t $GHCR_ALL_DEVOPS_IMAGE_NAME\:$DEVOPS_IMAGE_VERSION \
-t $GHCR_ALL_DEVOPS_IMAGE_NAME\:$TIMESTAMP \
--push .

Build the AWS DevOps Image

docker buildx build --platform $PLATFORMS --target aws-devops --pull \
-t $AWS_DEVOPS_IMAGE_NAME\:latest \
-t $AWS_DEVOPS_IMAGE_NAME\:$DEVOPS_IMAGE_VERSION \
-t $AWS_DEVOPS_IMAGE_NAME\:$TIMESTAMP \
-t $GHCR_AWS_DEVOPS_IMAGE_NAME\:latest \
-t $GHCR_AWS_DEVOPS_IMAGE_NAME\:$DEVOPS_IMAGE_VERSION \
-t $GHCR_AWS_DEVOPS_IMAGE_NAME\:$TIMESTAMP \
--push .

Build the GCP DevOps Image

docker buildx build --platform $PLATFORMS --target gcp-devops --pull \
-t $GCP_DEVOPS_IMAGE_NAME\:latest \
-t $GCP_DEVOPS_IMAGE_NAME\:$DEVOPS_IMAGE_VERSION \
-t $GCP_DEVOPS_IMAGE_NAME\:$TIMESTAMP \
-t $GHCR_GCP_DEVOPS_IMAGE_NAME\:latest \
-t $GHCR_GCP_DEVOPS_IMAGE_NAME\:$DEVOPS_IMAGE_VERSION \
-t $GHCR_GCP_DEVOPS_IMAGE_NAME\:$TIMESTAMP \
--push .
