buildx VS kaniko

This is great! I’ve been waiting a long time for this and it seems like more debug features are in the pipeline too: https://github.com/docker/buildx/issues/1104

Docs: https://docs.docker.com/engine/reference/commandline/buildx_...

Container engine: Docker v23.0.4 | Buildx v0.10.4

ARCH=amd64 # change to 'arm64' for M1 VERSION=v0.10.4 curl -LO https://github.com/docker/buildx/releases/download/${VERSION}/buildx-${VERSION}.darwin-${ARCH} mkdir -p ~/.docker/cli-plugins mv buildx-${VERSION}.darwin-${ARCH} ~/.docker/cli-plugins/docker-buildx chmod +x ~/.docker/cli-plugins/docker-buildx docker buildx version # verify installation

wget -O /tmp/docker/cli-plugins/docker-buildx https://github.com/docker/buildx/releases/tag/v0.10.4/buildx-v0.10.4.linux-amd64

Your particular one looks somewhat like https://github.com/docker/buildx/issues/1595.

Now, we have examples of the actual definitions for a single application’s docker container. Notice that we set the contexts key here which references the dependency targets we just defined. You can basically think of this like the depends_on block if you’ve used Terraform before. The args key let’s us populate the ARG variables in the Dockerfile. This is what is ultimately different between each of the containers. In the future, the buildx team might support using for_each loops like in Terraform but for now each block will have a bit of duplication.

Now as bonus we i will add how to use this techniques to build a multi arch build container. Maybe you have the same application but you need to run it in arm or riscv architecture. For this we can use the buildx plugin from docker https://github.com/docker/buildx.

Third step is docker/setup-buildx-action configures buildx, which is a Docker CLI plugin that provides enhanced build capabilities.

If all you need to do is build container, you can use https://github.com/GoogleContainerTools/kaniko

Kaniko for building the container images

kaniko

You should maybe look into Kaniko or use some other build tool

If you are using the docker socket just for building container images, you might want to look into kaniko. It doesn't use docker to build images. If you use the socket also for starting containers (we are actually doing that in our CI pipelines), you could think about limiting the pods Kubernetes schedules on a node (you can change the default of 110 using the kubelet config file).

Check out Kaniko for building containers https://github.com/GoogleContainerTools/kaniko . Only issue is it doesnt support windows containers.

It took less than 5 minutes to install. It quickly analysed the repo and identified easy ways to make the project more secure. Priya Wadhwa, Kaniko

I'd suggest to take a look at the Kaniko project, combined with custom container images in Lambda functions.

kaniko is a tool that allows you to build container images inside Kubernetes without the need for the Docker daemon. Effectively, it allows you to build Docker images without docker build.

Kubernetes prefers to pull containers from registries. You may be able to work around it by specifying a local image in your Kube manifest. Both https://github.com/GoogleContainerTools/kaniko and/ or https://www.devspace.sh/ may help.
