A Vagrant provisioned VM to run Docker containers in.
## Prerequisites
- Vagrant
- VirtualBox
- Ansible
## Usage
$ git clone git@github.com:SeerUK/OSXContainerHost.git
$ vagrant up
$ export DOCKER_HOST=tcp://192.168.200.2:2375
(Or alternatively, add: export DOCKER_HOST=tcp://192.168.200.2:2375
to whatever shell rc is relevent to your system)
You can also adjust the RAM and CPU count by modifying the following environment variables:
$ export OCH_CPUS=8
$ export OCH_MEMORY=8192
The defaults are 4 CPU cores, and 4096MB of memory.
## Things to be wary of
- NFS is configured to map all activity in
/Users/
to the uid and gid you run Vagrant as. This will also affect volumes in containers if they are mounted from the/Users/
folder (which I imagine most will be...). Realistically, for most use-cases this shouldn't be a problem, but it is something to be aware of. Please suggest a better solution if there is one. - Docker containers are created inside the VM, the images are downloaded inside the VM. Everything happens in there; therefore, if you remove and recreate the VM you will lose all of your existing containers.
