Docker myths and receipts. Mac OS X

  • VMWare Fusion and Parallels Desktop are better then VirtualBox in performance and stability.

  • At the moment of writing the Kinematic app sometimes can't do the work. If you have general experience in unix and want to use Virtual Box, I recommended installing a test build and update it periodically rather than using a VirtualBox installed with the Docker Toolbox. Maybe it will get fixed later.

  • Tired to type $ docker full_command every time? Set up the bash-completion with docker extension and enjoy.

  • Docker-machine is a nice tool. Use it to create a Docker virtual machine and open a terminal.

airgri:~ gri$ docker-machine create --driver virtualbox dev

Boot2Docker version 1.8.1, build master : 7f12e95 - Thu Aug 13 03:24:56 UTC 2015
Docker version 1.8.1, build d12ea79
docker@dev:~$
  • If you see an error

Error creating machine: Get https://api.github.com/repos/boot2docker/boot2docker/releases: dial tcp: lookup api.github.com: no DNS servers

add a resolving server to your /etc/resolv.conf, like "nameserver 8.8.8.8"

Of course, OSX will overwrite it on next reboot, but you don't need it too often.

  • docker-machine (as well as boot2docker) mounts the /Users folder from a host Mac OS to the /Users folder of a virtual machine. Not to a docker container.
	docker@dev:~$ mount |grep Users
	none on /Users type vboxsf (rw,nodev,relatime)
