First, make sure you are using Swarm as your orchestrator. Give it a try with a few simple steps. Swarm uses the Docker command line or the Docker Compose file format with a few additions.Start by downloading and installing the right version.I have the latest Docker Desktop for M1 installed, and Rosetta. Docker Desktop is freely available in a community edition, for Windows and Mac. Make sure Swarm is selected and hit Apply if needed.Run Docker without Docker Desktop on macOSInstall Docker Desktop.Install a Docker Engine and Docker Compose. Yet when it goes to run them I get the error: runtime: failed to create new OS thread (have 2 already errno22)Superset does not have official support for Windows, so we have provided a VM workaround below. When I run docker compose up percona I can see the amd64 images being downloaded, and updated.This post does in no way discourages organizations in paying and I believe that Docker Inc. Usually this is not a cause for concern as a company with revenue greater than $10 million would be able to afford Docker Desktop's $5 per user/month starter pricing. It will remain free for personal and open-source projects and for organizations smaller than a certain size.
Troubleshoot view comes up, but the buttons there don’t do anything.With the disclaimer out of the way, let us deep dive into explaining a little around what is free, what is paid and how exactly can we continue to use "containers", the core technology, without having to pay for Docker Desktop.Download Docker for Mac Be aware, that it still is in public beta, and Docker claims that some functionalities might change before a public release. Menu bar whale icon is not showing. Docker for Mac Desktop is stuck in Updating state. Troubleshooting actions should work. Menu bar whale icon should show. Docker Full Conceptual ArchitecturalThis digression is just meant to ease the rest of the discussion. This is by no means a full conceptual architectural explanation of how Docker works and I would recommend exploring other resources on the web for that purpose. I'll try to break down and explain each term. Experts who know Docker can skip this part.Docker can mean a lot of things. Download avro keyboardIt is responsible for the container lifecycle and isolation of physical resources (compute, memory, storage) that containers can access. It is an open source software that runs on linux as a daemon that makes it possible to run containers on top of Linux kernel. Docker Engine - The core technology behind Docker. Docker engine only runs on Linux. This is important to understand. Any OS that is flavour of Linux. That is where Docker Desktop comes in. Docker Desktop - Since Docker Engine only runs on Linux, developers who use Windows and macOS for software development cannot run the engine until they spin up a virtual machine (VM) that runs linux. Again, this is open source software. This consists both of docker and docker-compose commands. This list is not exhaustive and they maybe more ways to do this. I discussed two approaches that I've tried on my development environment (Macbook Pro 13" 2020 Intel Chip). Company's other revenue comes from Docker Hub.The way to continue to run and build applications for containers on macOS would be run Docker Engine on a Linux VM. So, I completely sympathise with the move for trying to earn revenue from a product that their software developers have worked so hard to develop. Is only trying to get large companies to pay for the convenience that Docker Desktop offers when developing applications. Docker Desktop is meant to be used during software development, it does not play a part in containers that run on production-like environments, where only Docker Engine is mostly involved.Docker Desktop is not the core technology that runs containers, it only aims to make it easier to develop software on Windows/macOS that runs in containers. Minikube is used to run a Kubernetes cluster on local environment. MinikubeSo far, minikube has emerged the easiest drop-in replacement for Docker Desktop. Sometimes this is not enough and it leaves certain things so I recommend searching for "uninstall docker desktop on macos" and follow a guide for full cleanup. Know what you're doing before running this. All mapped volumes will be lost. Adding a new port mapping.Vagrant delete - This deletes the VM with all the data. Just run vagrant up to spin up the VM.Vagrant reload - for reloading the VM for any changes made to the config e.g. This does not delete any data. On macOS, minikube runs on a lot of virtualization technologies, but hyperkit is the easiest to use.70 docker run hello-world Vagrant CheatsheetVagrant suspend - stop the VM for saving system resources. That can be done my adding forwarded_port entries in Vagrantfile as mentioned above. How they exactly do it is unknown, although it must involve some port mapping via hyperkit, but we must do this manually.Both in the minikube and virtualbox guides above, we make the IP address of the VM available under docker.local hostname so to access any services we must use that hostname instead of using localhost.Using Vagrant we can actually do double port mapping (between container ↔ linux and linux ↔ host) to access stuff on localhost. Caveats Accessing PortsDocker Desktop makes it very convenient to access services/apps running on containers by making everything available on localhost. Some examples have already been provided in the Vagrantfile for reference. Use vagrant reload after changing the file. ![]() I have not delved into the reasons of it, but that has made to stick to it. But for some strange reasons, I saw a huge jump in performance in read/write performance on MySQL when using vagrant + virtualbox combination. PerformanceIf you're using minikube, performance more or less remains the same because same underlying virtualization technology (hyperkit) is being employed. Thankfully, backing up volumes is easy and it can be put in a cronjob on the VM/host if needed.
