buildx VS hub-feedback

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.

image: this key specifies the image this container is based on to be created. It can be a local image or an image from the Docker hub.

Finally, we can upload our application to Docker Hub so that other people can use the image we created. To do this, follow the steps below:

Pull the official Docker distribution of pgAdmin 4 from the Docker Hub repository with the following command:

To use Docker Scout, you'll first have to have a Docker Hub account. Follow the installation instructions for Docker Scout on GitHub. Once Docker Scout is installed, you can sign in to Docker Hub on the command line with the docker login command.

Go to Docker Hub, sign up, and log in to your account's overview page.

There are a lot of docker-compatible registries almost every cloud provider has its registry but for this article, we will use the docker registry called docker hub. Go to the website create a new account and sign in then you can push or pull images.
