Increase your disk size for boot2docker


You searched for this article, so I assume you know what boot2docker is and are using it. That’s good, so am I.

But how many times have you got errors like no space left when you tried to pull a new image and running a command with container? I’ll tell you what, there’s a way to increase your disk size.

Find ~/.boot2docker/profile or create one if you cannot find it. For Windows, try %USERPROFILE%/.boot2docker/profile. There’s a configuration called DiskSize, change it to any size you want.

Make the whole configuraion file look like:

# boot2docker profile filename: /Users/lxie/.boot2docker/profile
Init = false
Verbose = false
Driver = "virtualbox"
SSH = "ssh"
SSHGen = "ssh-keygen"
SSHKey = "/Users/lxie/.ssh/id_boot2docker"
VM = "boot2docker-vm"
Dir = "/Users/lxie/.boot2docker"
ISOURL = "https://api.github.com/repos/boot2docker/boot2docker/releases"
ISO = "/Users/lxie/.boot2docker/boot2docker.iso"
DiskSize = 32000
Memory = 2048
SSHPort = 2022
DockerPort = 0
HostIP = "192.168.59.3"
DHCPIP = "192.168.59.99"
NetMask = [255, 255, 255, 0]
LowerIP = "192.168.59.103"
UpperIP = "192.168.59.254"
DHCPEnabled = true
Serial = false
SerialFile = "/Users/lxie/.boot2docker/boot2docker-vm.sock"
Waittime = 300
Retries = 75

Destroy your existing boot2docker-vm by running boot2docker destroy, and then use boot2docker init to create a new one.

Enjoy your new environment!
