Download Docker Desktop Macos
Dibe Naro
[UPDATE]: I came across this overview in a blog post on docker.com from 2016 which seems to be more or less what I am looking for, but I do not know enough of Docker to judge whether that information is still correct (or even relevant) today.
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).
As far as I'm aware docker is functionally incompatible with MacOS. I have docker desktop running on my Macbook and to the best of my knowledge this is achieved by docker desktop creating a Linux virtual machine and running the Docker engine in that.
That may be the case, I don't know your needs. But be aware that you may be using some features of docker desktop that you didn't realise were "features". For example docker bind mounts are a core concept in docker, however to get them to work on your Mac, docker desktop must also take responsibility to bridge the gap between MacOS and the Linux virtual machine.
To connect the host CLI to the VM, I had to use SSH port forwarding to connect a socket on the host to /var/run/docker.sock. You need to install and configure SSH on the Debian server and open a port from the UTM settings so the host can connect through the network to the VM's SSH port. In UTM, I forwarded host port 22022 to guest port 22, so in the below steps, you'll see references to port 22022.
There was a question below about whether or not Docker can work with Ubuntu 22.04 on Apple Silicon. The answer is YES. The catch or hang up that people are hitting is when they try to use "Docker Desktop" on Ubuntu (instead of directly on macOS). This tries to run a nested virtualization scenario and Apple does not have this instruction set available on the M1 series of Apple Silicon devices. The key, however, is to just use Docker itself with something like a tutorial from here: -to-install-and-use-docker-on-ubuntu-22-04
UPDATE 5/4/2022Based on a support email I received from parallels.com, the Apple store version I had installed was parallels desktop and is not the same as the parallel Pro version I purchased on the parallels.com web site. I was sent the following link for future information, but in a nut shell, I do believe that parallels pro was required in my case.
So you might gain nothing trying to use docker, because it also uses a VM (on MacOS).
Which is only logical because containers require the hosts kernel and the kernel of macos is different from the linux kernel.
According to the project page (GitHub - nextcloud/all-in-one: Nextcloud AIO stands for Nextcloud All In One and provides easy deployment and maintenance with most features included in this one Nextcloud instance.), I am to pull the AIO docker, and use the following script to load it:
Hi, if you should be using Docker Desktop, you are probably running into docker desktop - connecting to docker socket inside container with different user than root is broken after updating to 4.19 Issue #2450 nextcloud/all-in-one GitHub
I've spent a lot of time with the internals of running Docker or Kubernetes on the desktop. In my 3 years at Google, I built and maintained minikube, which runs Docker and Kubernetes on macOS, Linux, and Windows (and many other container projects). So I'll review that first.
A project that runs on Linux and macOS that spins up a docker environment in a virtual machine using Lima. Volume mounts may be faster with Lima, but the project is still in early stage development and may introduce breaking changes according to the README. Colima doesn't ship with a GUI and has a UX similar to minikube. Promising technology if you're willing to be on the cutting edge.
A utility for building docker images. I've spent a lot of time in this area, and built many tools that ship OCI-compatible images that run on Docker. Doesn't actually provide a container runtime. Linux only.
Now that we have a clearer understanding of how Docker manages the filesystem, it is easily understandable how risky it can be to use a container without proper data persistency layer. This is exactly where docker volumes come in handy.
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.
Before we start with a quick check of Rancher Desktop let me tell you something about the default host volume mounts Rancher Desktop provides. Per default your home folder and the folder /tmp/rancher-desktop are available for mounting them into your containers.
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.
Please Note: The docker engine requires the Windows Features: Containers and Microsoft-Hyper-V to be installed in order to function correctly. You can install these with the chocolatey command:
I am trying to perform `docker pull container-registry.oracle.com/middleware/fmw-infrastructure:12.2.1.3` on a mac running Docker Desktop on Mojave. I was finally able to login successfully after fiddling with my Docker config.json, but I am not able to pull any images from the Oracle Container Registry, as it appears that the registry is unavailable. Whenever I have Docker running and I try to pull I am prompted with the following
Docker Engine (docker CLI), is my preferred approach for Linux distros. However, for macOS, there is no stand-alone installation for it. The official documentation states that the Docker Engine is provided either via the Docker Desktop or via static binaries installation. As you can see here, the officially provided binaries include only the Docker client, without the dockerd daemon which is required to run containers.
One can still use the deprecated docker-machine using brew package manager with the support of some virtual machine/hypervisor, e.g.: xhyve. However, the docker-machine project seems to be deprecated and probably alternative ss to use its fork rancher machine, instead. Following such an approach on a new M1 Mac might be considered a bit risky, and thus we can leave it aside for now.
If your system is under more pressure and uses close to the amount of memory allocated in Docker desktop resources, it may start to swap and performance will suffer. Adding more memory may help it run better.
The orb and orbctl commands are included to manage and use OrbStack and its Linux machines from the command line. The latest Docker command-line tools (docker, docker compose, docker buildx, etc.) are also included.
When you start OrbStack, these commands are automatically installed if you don't already have them. However, if you already have them installed from another source (such as Docker Desktop or Homebrew), they will be left alone. To switch to OrbStack's versions, uninstall or delete the old ones (e.g. /usr/local/bin/docker*) and restart the app.
I uninstalled docker desktop and reinstalled only the docker engine in Ubuntu Linux.
The problem is with docker desktop it somehow closes the port.
I do not have firewall running in my ubuntu as well.
I needed to run my docker engine using sudo.
Note that if the container fails to come up due to something like a Docker build error, you can select Reopen in Recovery Container in the dialog that appears to go into a "recovery container" that allows you to edit your Dockerfile or other content. This opens the docker volume with the cloned repository in a minimal container and shows you the creation log. Once you are done fixing, use Reopen in Container to retry.
