Configure these settings by editing the environment file, located at. In addition, you can use the Problems panel (Ctrl+Shift+M on Windows/Linux, Shift+Command+M on Mac) to view common errors for Dockerfile and docker-compose.yml files.Some Docker installations, including Windows and macOS, come with Docker Compose. Editing Docker files You can get IntelliSense when editing your Dockerfile and docker-compose.yml files, with completions and syntax help for common commands.Double-click Docker.app in the Applications folder to start Docker. Double-click Docker.dmg to open the installer, then drag the icon to the Applications folder. Download Docker here and save to your On-Premise Console device.
Docker Config Files Free For PersonalExperts who know Docker can skip this part.Docker can mean a lot of things. Has all the rights to monetize their product.If you are running Grafana in a Docker image, then you configure Grafana using environment variables rather than directly editing the configuration file.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.This digression explains terminology around Docker. 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. Recently announced that Docker Desktop would no longer remain a free product for large organizations. Docker Engine - The core technology behind Docker. Docker Inc - It is a USA based company that produces some open-source and not-open source software that makes it easier to develop, test and run applications in containers. This 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. Docker CLI - This is the CLI that developers usually use to interact with the docker engine. Docker engine only runs on Linux. This is important to understand. Any OS that is flavour of Linux. The engine can run on a physical or a virtual machine, but it can only run on top of a Linux kernel i.e. It is responsible for the container lifecycle and isolation of physical resources (compute, memory, storage) that containers can access. 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. 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. This post does assume some working knowledge of Docker.Before doing this, uninstall Docker Desktop by removing /Applications/Docker.app. 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). 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. But it also runs a docker daemon that can be used to run 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. If you just want to stop the VM use vagrant suspend.For every port that we want to natively access on macOS host, we need to modify the Vagrantfile to add port forwarding. 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. ![]() Volumes are generally used for persistent databases like MySQL, PostgreSQL etc.There are ways in which vagrant allows you to map folders to the VM, that would again be 3 layer-mapping like ports mentioned above, but becomes very complicated because of permission issues in the way Docker works. This means that by destroying the VM we will lose access to the data in the volumes. This is very important to remember. Volumes and Data PersistenceSince the Docker Engine is running on the VM, any volumes created or mapped will be present on the Linux VM, not on the macOS (host). 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. I could if I put in some extra hours, but the point is that it is cumbersome.My advice would be to backup volumes to a location on the VM and pull that backup to the host either via scp if you're using minikube or vagrant has a default drive mapped at /vagrant which can be used for backup. Brest unitaller app for macI am yet to try minikube + virtualbox combination.Minikube actually runs a kubernetes cluster on the VM so if that is not needed, doing a minikube pause will make sure k8s cluster related containers are suspended so they do not consume any system resources. I have not delved into the reasons of it, but that has made to stick to it.
