“rsync” was not detected as installed in your guest machine

Question

I'm trying to setup Vagrant with docker as a provider but when running

vagrant up --provider=docker --debug

I get this error:

"rsync" was not detected as installed in your guest machine. This is required for rsync synced folders to work. In addition to this, Vagrant doesn't know how to automatically install rsync for your machine, so you must do this manually.

Vagrantfile

require 'yaml'

Vagrant.configure("2") do |config|

  user_config = YAML.load_file 'user_config.yml'

  config.vm.provider "docker" do |d|
    d.build_dir = "."
    d.has_ssh = true
    d.ports = user_config['port_mapping']
    d.create_args = ["--dns=127.0.0.1","--dns=8.8.8.8", "--dns=8.8.4.4"]
    d.build_args = ['--no-cache=true']   end

  config.vm.hostname = "dev"

  config.ssh.username = "it"   config.ssh.port = 22   config.ssh.private_key_path = ["./initial_ssh_key", user_config['ssh_private_key_path']]   config.ssh.forward_agent = true

end

Dockerfile

ADD initial_ssh_key.pub /home/it/.ssh/authorized_keys RUN chown it:it /home/it/ -R RUN echo "Host * \n\tStrictHostKeyChecking no" >> /etc/ssh/ssh_config

CMD exec /sbin/init

Note: I'm on Mac OS X 10.12 and I've installed vagrant, virtualbox and docker I have rsync installed and added to my PATH in the host machine. Also, the same vagrant and docker configs works perfectly on a ubuntu host.

How do I install rsync in the guest machine? Or is something else wrong with my config? Any ideas?

I don't see you exposing any ports on a docker, try exposing 873 or whatever rsync is using with d.expose = [873] — German Rumm

You may want to give the alternative boot2docker box a try: https://github.com/dduportal/boot2docker-vagrant-box as it contains rsync while the hashicorp/boot2docker, which is used by default, seems to lack this!

If doing so, you must add the follwong line to your docker provider config (of course adopted to your system):

d.vagrant_vagrantfile = "../path/to/Vagrantfile"

This is because you're changing the docker provider host vm as described in the vagrant docker provider documentation.
