This read-write layer enables the process running in the container to read and write files during its run. Ĭontainers are nothing but images with a read-write layer on top of it. Now when the “docker run” command is executed with the volume parameters, it is the “directory” on the guest OS (boot2docker ‘default’ VM ) which gets mounted onto the container. This ensures access of the host(OSX) directory contents to the guest OS (boot2docker ‘default’ VM). “docker run” command run the docker image in a container on the “default” VM.Ī directory present on the OSX (host machine) is first mounted to a directory of the same name(need not be of the same name) on the VM.Boot2Docker is launched in a virtual machine named ‘default’ on VirtualBox.If you execute the following command in the shell you will see that the IP address returned is different from the HOST machine.

The docker daemon is running on the linux VM and you use the docker client to connect to it. Instead of running directly on the host, docker runs on a small light weight scaled down Linux virtual machine named ‘default’.

I haven't tried it personally because I'm waiting for it to hit Windows stable in a few weeks.On a Linux installation Docker runs directly on the host but on MAC OSX it runs in a slightly different manner. In theory WSL 2 should be even better because WSL 2 can be used as a back-end and your code would be living directly in WSL 2's file system instead of in a mounted drive. There's thousands of people on Windows taking my Docker course and no one with this set up has contacted me yet saying the performance was bad once they've disabled Windows defender, where as I've had a bunch of people on MacOS mentioning poor volume performance with Docker Desktop (not everyone but some). WSL 1 is really doing nothing except allowing the Docker CLI / client to talk to Docker Desktop after doing a bit of configuration. It's just a Docker volume from a Windows mounted drive into the Docker Desktop VM. It's because Docker Desktop is doing the real work here. Wow this is the first time I hear something good about WSL1 IO performance.
#MAC OSX DOCKER IMAGE FOR MAC#
Is there anyone who compared the Docker on WSL2 with the Docker Desktop for Mac so far? VSCode seems to be another option which is WSL2-friendly but I hear people switching back to PHPStorm from VSCode because it's not that advanced for PHP development yet. I really like the idea of WSL2 with dynamic CPU and memory allocation with Hyper-V but not sure how efficient the file syncing between Windows and Linux Subsystem is.īecause I use PHPStorm which is very good at indexing and finding stuff, I need to access the files from both Linux subsystem and Windows. Even if disk IO looks ok on Docker Desktop for Mac, it is not even close to native performance. It works fine with the osxfs tweaks but I don't like the idea of allocating constant CPU and memory resources to the VM and I really feel what I am sacrificing when I switch to native Docker environment on Linux.

I currently use Docker Desktop for Mac on my MacBook Pro 13" mid-2012 with 16gb of ram. Switching from one OS to another for a single software is not convenient at all. I don't consider the native Docker on Linux for now because I need softwares that are not available on Linux everyday. I am fan of docker as a web developer that should deal with different versions of PHP and nodejs simultaneously on various projects everyday.
