brew cask install ĭocker on Mac is a GUI tool, so you need to use Homebrew Cask for the installation. It means that instead of the standard download and drag-and-drop process, you can use this.
#MAC FOR DOCKER SOFTWARE#
Homebrew Cask is a Homebrew extension for installing GUI software on Mac. Homebrew, by default, can only install command-line tools.
If you have ever installed any GUI software on Mac the “standard way,” you probably know that it normally requires downloading the package, opening it, and installing by the drag-and-drop method to the Application folder. “What’s Homebrew Cask, and why can’t I install Docker with brew install docker?” you might ask. For Docker installation, however, you’ll need to use Homebrew Cask. To install pretty much anything, you can simply type brew install Īnd wait a few seconds. It’s handy and easy to use, which is why it’s also popular. It works on the command line and allows you to install software for your Mac.

In this post, you’ll learn how to install Docker on Mac OS using Homebrew.ĭon’t know Homebrew yet? It’s a package manager for macOS. It simplifies many operational aspects of running applications. It provides an easy way to safely move code from one machine to another without worrying about dependencies and server versions. In addition it can automatically set-up a secure registry on Kubernetes, which will be the topic of a later post.Docker on Mac with Homebrew: A Step-by-Step Tutorialĭocker has changed the way developers work. The registry tool also has options to retrieve the certificate from a URL or a Kubernetes secret.
(out)Adding certificate to local machine. reg-tool.sh install-cert -cert-file ca.crt -reg-name test-docker-reg:5000 -add-host 192.168.1.103 test-docker-reg A simple way to do this is to add an entry to /etc/hosts< e.g:Īnd now you should be able to push and pull to the registry:ĭocker tag alpine:latest test-docker-reg:5000/test-imageĭocker push test-docker-reg:5000/test-imageĪs there's some non-obvious steps here, and it's a common problem, I've written a tool to do this as a one-liner on Linux or Mac:

You'll need to restart Docker for Mac for the change to take effect.Īfter this, on both Linux and Mac, you will probably need to make the registry address resolvable (if you're using a self-signed cert it probably means it's running on an internal network without a public domain name).
Sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ca.crt The correct solution (thanks to Justin Cormack) is to add the certificate to the Mac's keychain, which will be picked up by Docker for Mac e.g: The above solution doesn't work, as Docker for Mac relies on a internal VM whose filesystem gets wiped on restarts. With the Mac, however, things are a little different. Sudo cp ca.crt /etc/docker/certs.d/test-docker-reg\:5000/ Sudo mkdir /etc/docker/certs.d/test-docker-reg\:5000 This post will look into some of the issues around accessing registries with self-signed certificates from clients, including Docker for Mac.ĭistributing certificates to Linux Docker clients is pretty straightforward, as it just means copying the certificate to the correct directory (for the purposes of this post, I'm assuming you know how to create a self-signed cert for the registry): If your registry isn't running on a public domain, you're probably using a self-signed certificate for this purpose. When running a registry, it's essential to make sure your clients can access it easily and securely. The Docker registry image has over 10 million pulls on Docker Hub, so it's safe to say that a lot of people out there are making use of it.
