Setting up boot2docker
manually on Parallels
Since I don’t have Parallels Pro, I run Docker on my older Macs like this:
- Download a recent release and put the ISO someplace safe
- Create a new VM manually by dragging the ISO to Parallels (use the
Shared
orNAT
network type) - After first boot, use
fdisk
to create a primary partition in/dev/sda
and format it usingmkfs.ext4 -L boot2docker-data /dev/sda1
- Reboot so that it gets mounted and used for certificate storage
- Do
brew install docker
(which gets you the CLI) - Set up port forwarding for port 2376 and a local port to the VM’s SSH port
- SSH into the VM (
docker
/tcuser
) and copy the*.pem
files from/var/lib/boot2docker/tls
to your~/.docker
folder - Set and export
DOCKER_HOST
andDOCKER_TLS_VERIFY
accordingly:
export DOCKER_HOST=localhost:2376
export DOCKER_TLS_VERIFY=1

Building The Docker Registry From Scratch (on ARM, too!)
Very simple, really, once you have Go installed. Quite quick on a Raspberry Pi 2, too:
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$PATH
# this fetches godep and golint
go get github.com/tools/godep github.com/golang/lint/golint
# this fetches and builds the registry
go get github.com/docker/distribution/cmd/registry
# test it with the default config
$GOPATH/bin/registry $GOPATH/src/github.com/docker/distribution/cmd/registry/config.yml
