Wow, check out the difference in size. Alpine is about 30x smaller than Debian. The Docker Hub has handled a ton of pulls. By investigating its public API we can see that Debian has gotten 35,555,107 pulls and Alpine has gotten 135,136,475 pulls at the time of this article. $ docker images REPOSITORY TAG IMAGE ID CREATED SIZE abiodunjames/example-node-app latest be083a8e3159 7 minutes ago 83.2MB Running a Docker image. You run a Docker image by using the docker run API. The command is as follows: $ docker run -p80:3000 yourusername/example-node-app. The command is pretty simple. Docker security refers to the build, runtime, and orchestration aspects of Docker containers. It includes the Dockerfile security aspects of Docker base images, as well as the Docker container security runtime aspects—such as user privileges, Docker daemon, proper CPU controls for a container, and further concerns around the orchestration of Docker containers at scale. Anyways, here's ho to increase the size of swap available in Docker. When you try to set up an OracleDB inside a docker container, you'll probably need this. Note: This works only with the native virtualization version of Docker for Mac. You could increase this size, or you could tidy up some of the unused content. You can prune these down easily, using the prune command. Go carefully though, because if you trash all your images then they’re going to have to be pulled back down from their repository or rebuilt, and that can take some time.

Docker images can support multiple architectures, which means that a singleimage may contain variants for different architectures, and sometimes for differentoperating systems, such as Windows.

When running an image with multi-architecture support, docker willautomatically select an image variant which matches your OS and architecture.

Most of the official images on Docker Hub provide a variety of architectures.For example, the busybox image supports amd64, arm32v5, arm32v6,arm32v7, arm64v8, i386, ppc64le, and s390x. When running this imageon an x86_64 / amd64 machine, the x86_64 variant will be pulled and run.

Docker Desktop provides binfmt_misc multi-architecture support,which means you can run containers for different Linux architecturessuch as arm, mips, ppc64le, and even s390x.

This does not require any special configuration in the container itself as it usesqemu-static from the Docker forMac VM. Because of this, you can run an ARM container, like the arm32v7 or ppc64levariants of the busybox image.

Buildx (Experimental)

Docker is now making it easier than ever to develop containers on, and for Arm servers and devices. Using the standard Docker tooling and processes, you can start to build, push, pull, and run images seamlessly on different compute architectures. Note that you don’t have to make any changes to Dockerfiles or source code to start building for Arm.

Docker

Docker introduces a new CLI command called buildx. You can use the buildx command on Docker Desktop for Mac and Windows to build multi-arch images, link them together with a manifest file, and push them all to a registry using a single command. With the included emulation, you can transparently build more than just native images. Buildx accomplishes this by adding new builder instances based on BuildKit, and leveraging Docker Desktop’s technology stack to run non-native binaries.

For more information about the Buildx CLI command, see Buildx.

Install

How to increase the size of the base docker for mac os
  1. Download the latest version of Docker Desktop.

  2. Follow the on-screen instructions to complete the installation process. After you have successfully installed Docker Desktop, you will see the Docker icon in your task tray.

  3. Click About Docker Desktop from the Docker menu and ensure you have installed Docker Desktop version 2.0.4.0 (33772) or higher.

Build and run multi-architecture images

Run the command docker buildx ls to list the existing builders. This displays the default builder, which is our old builder.

Create a new builder which gives access to the new multi-architecture features.

Alternatively, run docker buildx create --name mybuilder --use to create a new builder and switch to it using a single command.

Base

Switch to the new builder and inspect it.

Test the workflow to ensure you can build, push, and run multi-architecture images. Create a simple example Dockerfile, build a couple of image variants, and push them to Docker Hub.

Where, username is a valid Docker username.

Notes:

  • The --platform flag informs buildx to generate Linux images for AMD 64-bit, Arm 64-bit, and Armv7 architectures.
  • The --push flag generates a multi-arch manifest and pushes all the images to Docker Hub.

Inspect the image using imagetools.

The image is now available on Docker Hub with the tag username/demo:latest. You can use this image to run a container on Intel laptops, Amazon EC2 A1 instances, Raspberry Pis, and on other architectures. Docker pulls the correct image for the current architecture, so Raspberry Pis run the 32-bit Arm version and EC2 A1 instances run 64-bit Arm. The SHA tags identify a fully qualified image variant. You can also run images targeted for a different architecture on Docker Desktop.

You can run the images using the SHA tag, and verify the architecture. For example, when you run the following on a macOS:

In the above example, uname -m returns aarch64 and armv7l as expected, even when running the commands on a native macOS developer machine.
