Rancher Desktop is an electron based application that wraps other tools while itself providing the user experience to create a simple experience.On MacOS and Linux, Rancher Desktop leverages a virtual machine to run containerd or dockerd and Kubernetes. Windows Subsystem for Linux v2 is leveraged for Windows systems.All you need to do is download and run the application.
Rancher Desktop installs a new Linux VM in WSL2 that has a Kubernetes cluster based on k3s as well as installs various components in it such as KIM (for building docker images on the cluster), helm cli and the Traefik Ingress Controller
To have a Linux host I was running a vagrant virtual machine with a docker inside. Rather heavy as a working environment! But recently I found a turnkey and easy-to-set-up solution to have Docker and Kubernetes on Mac without going through Docker Desktop. We will see a toolset to achieve that.
Lima can be compared to a kind of Windows Subsystem for Linux (WSL) but for Mac and a containerd for Mac. It wraps QEMU hypervisor with containerd runtime and nerdctl a replacement for the docker command. It is super simple to install with Homebrew:
By default, Rancher Desktop uses pass to securely store credentialspassed via docker login and nerdctl login. pass requires a small amountof setup if this is the first time it has been used on your machine. If you don'tintend to use docker login or nerdctl login you don't have to set uppass - just remember that if you use them in the future, you must set itup or you will run into errors.
This is the view for the default namespace, which is where your services will be deployed by default. You can view other namespaces by selecting them from the dropdown at the top left of the page. In the following screenshot I've selected the kubernetes-dashboard namespace, so you can see there's two deployments:
This installs a variety of resources in your cluster, but again, we need to patch one of the deployments. We need to add the --kubelet-insecure-tls argument to the metrics-server deployment, otherwise you'll see an error saying something like unable to fetch metrics from node docker-desktop. The following command patches the deployment:
Since Rancher Desktop version 1.1.0, which has been released a couple of days ago, you can finally disable the Kubernetes component just using containerd or dockerd as your container runtime. Also, the host volume mount performance is now as good what Docker Desktop provides.
When you are looking for a real drop-in replacement of Docker Desktop on macOS, Rancher Desktop got you covered. As Rancher Desktop provides dockerd as runtime beside containerd all commands like docker and docker-compose continue to work out of the box. Also, Visual Studio Code immediately recognizes Rancher Desktop when you use dockerd as container runtime.
There is now an easy way to pull a required image without running it from a Dockerfile, docker-compose.yml, or even from tests that use Testcontainers. Simply call up the context actions (Alt+Enter ) on the highlighted image name and select Pull Docker image.
docker run --user root --restart=always -v /var/run/docker.sock:/var/run/docker.sock -d -t -v /tmp/ozone:/tmp/ozone -p 8000:8000 --name ozone-daemon -listen=:8000 ozone2021/ozone-daemon:latest TODO does ozone folder need created in TMP?
docker rm -f ozone-daemon; docker build . -t ozone-daemon --progress plain; docker run --user root --restart=always -v /var/run/docker.sock:/var/run/docker.sock -d -t -v /tmp/ozone:/tmp/ozone -p 8000:8000 --name ozone-daemon -listen=:8000 ozone-daemon
I will show you, step by step, how to run a build server on a managed kubernetes instance. The build server will dynamically create a new environment when a pull request (PR) is opened in github, then delete the environment after the PR is closed. Long running branches (dev/main/epics) will be built when the PR is merged. Automated tests will be run against all environments.
Following installation, you then issue colima start when you want to start the daemon, and after that completes, you should find that docker CLI commands work as normal. The first time you do this is a little slower due to downloading the image and configuring it, but following that only takes a few seconds on my machine. You can of course use colima stop to shut it down to save resources on your machine if desired between docker sessions.
As a result, my personal .zsh_profile contains the following: alias docky="export DOCKER_HOST=unix:///Users/alex/.colima/true/docker.sock && colima -p true" to combine the two options above. I then just docky start and docky stop as needed to bring up the daemon and use my various docker-related tools
I opted to use the recommended stable Kubernetes release and the dockerd/moby engine - but I really like that it offered me the choice of containerd (nerdctl) in case that becomes handy in the future (and I understand from the docs that they can coexist too). 2b1af7f3a8
