Uninstall Docker For Mac

What is Docker?

Docker is the next step on long IT containerization way. What does it mean? Years ago, you could run each application/process in particular container, that application couldn’t go outside the container which it was run. It was very safe but difficult to manage and not sharable. So you couldn’t easy share your container to other machine or to other developers to reuse for example by open source community.

So, that solution was a little bit complicated and worked only on Linux. Today we have Docker, which allows you to run containers on all operation systems. What is important, this tool is not only modern but also easy to manage and easy to share to others developers.

Other ways to install it

In this post, I want to show you how to install Docker by using brew which installation process I wrote last time. For me, it’s the easiest and safest way. But there are a few other possibilities to install it on Mac OS.

Docker for Mac is a Docker Community Edition (CE) app. The Docker for Mac install package includes everything you need to run Docker on a Mac. This topic describes pre-install. I've been having some issues with Docker for Mac, and tried uninstalling and reinstalling. However, the uninstall procedure crashed halfway through. Ever since, I haven't been able to get Docker for Mac to work at all, which I suspect ha.

Docker.com – first method

First what you have to do is to go to Docker website and just download and run the .dmg file.

This is probably the easiest way, but unfortunately not the best. Using native install method you don’t have to install VirtualBox to run Linux, but sharing files between your Mac OS and systems in containers are really slowly. I can recommend that solution only if you want to test something or your project doesn’t use a framework with a lot of files.

Docker Toolbox – second method

Uninstall Docker Mac Os

It’s an app provided by Docker Company for Mac OS and Windows. The special feature in this toolbox is the requirement for VirtualBox, which will be a supervisor to run Linux. So, Docker is available as another machine in Docker environment. This toolbox contains also docker-compose (more below) and Kinematic, which allow you to manage your container by using GUI than a command line.

Install

I guess you have installed brew if not just follow this page and do everything that I’ve described.

For

If you are ready, open your terminal and type something like this:

If you have done it that you’ve received notice that docker-machine-driver-xhyve has to run as root, so you have to execute that commands:

Both commands will ask you for a password. Don’t worry to type it in a command line.

If everything goes ok then you can create your first docker machine, just type this command:

This command, as you suppose, creates a docker machine, using the xhyve driver.
--xhyve-experimental-nfs-share – this flag allows you to share each file in your /Users/ folder between Mac OS and Linux run on Docker.

Can't Uninstall Docker

Because you can have a lot docker machine, you can type this command in your terminal:

It registers a few variables, which allow you to use default docker machine without typing “default” each time.

Useful tools

Probably, you’ve noticed that with docker you installed also docker-machine and docker-compose. These tools are not required but they are the strength of docker.

docker-machine

This tool allows you to prepare a lot of docker machines on your Mac OS, so you can have a lot of containers on many Linux distributions. You can dump all available commands just by typing docker-machine --help but most likely you will use three of them:

I guess I don’t have to describe what exactly this commands do. It’s so obvious. One thing you need to know, if something goes wrong, just try to restart your docker machine.

docker-compose

The main goal of docker: you can write like this “one process = one container”, but each app requires a lot process it could be a PHP, HTTP server, some database etc. Of course, you can run containers for each process manually, which is not a big deal with 3 containers, but trust me it escalates very fast, so you need an easy tool to manage your container and to manage the dependencies because one container can require access to another container. For example, PHP app needs information from a database, but it doesn’t need access to HTTP server. Of course, and HTTP server requires access to PHP.

To work with docker-compose you need to create an YAML file called docker-composer.yml Trillion for mac. where you describe which container you want to create and how they are linked between each other.

That file can look like this:

As you can see, you are creating two containers, first, contains MySQL database and second one – a WordPress instance. This example is flattened, in normal case you should split WordPress instance to three another containers: PHP, HTTP server and one for WordPress files.

There is also created one volume, which contains files of MySQL database. This solution prevents loosing data when you turn off your Mac, or just reset docker-machine or this particular container.

If you want to read something more about parameters available in docker-compose file, you can just go to docker documentation.

docker-compose, as well as other tools, provides a lot of commands available from a terminal, the number one is:

This command runs all containers defined in your docker-compose file. If it is needed – rebuild and remove old unused containers.

How to use

Uninstall Docker For Mac Completely

Everything that you need is in the section above. You can manage of course each particular container directly from command line using command docker. But it’s just wasting a time.

Access by domain

Uninstall Docker For Mac Windows 7

Probably you want to access to your container by your web browser using some domains. You need to know what is IP of your docker machine and you can check it using command line just typing this:

You see IP and then use that IP in your /etc/hosts file.

Potential problems

Because you are trying to run Linux environment on Mac OS you can some across a lot strange problems if you want to use it in common work. Fortunately, you just need to follow some rules to enjoy work with docker.

Sharing files

If you installed a docker as described above you can share only files from your /Users/ folder. You can debug what is sharable directly on your docker machine, which can receive access directly from command line, like this:

Now, you are logged on your Linux and can browse to / and check is there /Users/ folder which contains files from your Mac OS. If you don’t see your files, just try to reinstall Docker and xhyve.

Speed of I/O process

Because docker needs transfer files between your Mac OS and Linux using the NFS it’s always more slowly then operation directly on your disk. So, if you want to boost up your application you have to remember to share only needed files. if you are backend develop you don’t share frontend javascript libraries, just put in into inside container.

Don’t forget to ignore cache and logs files!

Access via domain/IP

Restarting Mac OS or docker-machine sometimes restarts also IP of the docker machine. If you can’t connect to your docker just check the current IP using this command:

If it doesn’t work, you have to update domains in your /etc/hosts file.

What is Docker?

Docker is an app for building, bugging and testing containerized apps. You can run Docker on a Mac, Windows, or Linux machines. It allows developers to do everything necessary from start to finish to create and ship containerized apps.

If you’ve downloaded it to try it out and have decided not to use it, you may need to uninstall it. Here, we’ll show you how to do it.

Check running processes first

There are several steps needed to uninstall Docker on your Mac. The first is to get rid of the application itself, but before that, check there are no currently running processes.

  1. Go to Applications > Utilities and launch Activity Monitor.
  2. Look for any processes in the list that have “Docker” in their name.
  3. If you find any, select them and press the “Quit Process” button in the Activity Monitor toolbar.
  4. Quit Activity Monitor.

How to uninstall Docker manually

  1. In Finder, go to your Applications folder.
  2. Locate the Docker app.
  3. Drag it to the Trash and empty it.

That removes Docker, or at least the main application. It doesn’t get rid of all the files that were installed along with it. So, you’ll need to track those down and remove them.

  1. In Finder, choose the Go menu and select “Go to Folder.”
  2. In the text box, paste: ~/Library
  3. Click on the Application Scripts folder and look for “com.docker.helper”
  4. Drag it to the Trash.
  5. Now, click on the Caches folder and look for the com.docker.docker folder.
  6. When you find it, drag it to the Trash.
  7. Next, find the Containers folder, select it and look for “com.docker.docker” and “com.docker.helper” and drag those to the Trash.
  8. Check the Application Support folder for any files or folders with Docker in their name. If you find any, drag those to the Trash too.

How to uninstall Docker with CleanMyMac X

Once you’ve removed all those files and trashed the Docker application, it should be completely uninstalled. If all of that seems like a lot of work, there is an easier way. By using a dedicated uninstaller, like the one in CleanMyMac X, you can uninstall multiple apps in a few clicks.

There is something else to bear in mind. If you think you might use Docker again, but have decided to uninstall it because it seems to be causing problems on your Mac, you could try resetting it. That way you won’t have to download Docker for Mac all over again. Resetting an app means removing all of its settings and preferences files so that when you next launch it, it starts up as if it was a brand new copy of the application. You might find that it solves the problem.

The easiest way to reset an app is to use CleanMyMac X. Here’s how to do it:

  1. Download, install and launch CleanMyMac X (free trial available).
  2. In the left hand sidebar, in the Applications section, choose Uninstaller.
  3. When all the applications are listed, locate Docker and check the circle next to it.
  4. Click on the dropdown menu labelled Uninstall and choose Reset.
  5. Press the Reset button at the bottom of the window.
  6. Wait for it to finish and quit CleanMyMac X.

Docker will now have reset and the next time you launch it all its settings and preferences will have returned to their default. So, you’ll need to set it up again from scratch, but any problems it was causing your Mac should be gone.

Uninstalling Docker manually isn’t particularly difficult. But as you can see from the steps above, it’s time consuming and quite fiddly. You need to look in several different folders that are hidden away on your Mac. By far the easiest way to uninstall any app, is to use a dedicated uninstaller like the one in CleanMyMac X. However, before you uninstall it, you should consider resetting Docker, as that may well solve any problems you’ve been having. You can do that using CleanMyMac X too.
