Access Docker features when using Vagrant
I’ve been using Vagrant for some time and am now exploring Docker. I’ve always loved Vagrant for its simplicity. Right now, I’m trying to use the Docker provider within Vagrant. I’m using the following Vagrantfile:
Vagrant.configure("2") do |config| config.vm.provider "docker" do |d| d.image = "fgrehm/vagrant-ubuntu:precise" end end
My understanding is that I can just run
vagrant up. I can then run the Docker container using
vagrant docker-run -- <command>.
So far so good. What makes Docker so awesome is the fact that you can mess around and commit changes. I do not understand is how to incorporate this in my workflow when using the Docker provider for Vagrant. E.g. how do I run
docker commit to commit the state of the container? I’d expect some kind of
vagrant docker-commit, but this does not exist?
Edit: In hindsight, I think this is not the way you should be using Vagrant/Docker. Though it is claimed that both tools complement each other, my opinion is that they do not (yet) play really well together. Right now, we’re using Dockerfiles to build our images. Additionally, we made a set of bash scripts to launch a container.

Try to specify “has_ssh” to true, and ask Vagrant to use port 22 instead of 2222:
ENV["VAGRANT_DEFAULT_PROVIDER"] = "docker" Vagrant.configure("2") do |config| config.vm.provider "docker" do |d, o| d.image = "fgrehm/vagrant-ubuntu:precise" d.has_ssh = true o.ssh.port = 22 end end
vagrant up; vagrant ssh to access it.
Another option if you have same client version of docker at your host-host machine as docker server started inside boot2docker VM. In that case you can set
export DOCKER_HOST=tcp://:4243 (or 2375 depending on docker version)
and then access all docker features running local client:
docker ps -a
