Invalid user: 'vagrant:docker'

I have ubuntu 16.04.7 running vagrant version 2.2.10 and vagrant-proxyconf 2.0.10. Now whenever I run vagrant provision it fails to configure the proxy during the configuring proxy for docker step:

vagrant provision
==> default: Configuring proxy for Apt...
==> default: Configuring proxy for Docker...
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

chown -R vagrant:docker /home/vagrant/.docker

Stdout from the command:



Stderr from the command:

chown: invalid user: 'vagrant:docker'

When I had the older version of vagrant 2.2.5 I didn't receive this error...

Hi @adespain,

Thank you for reporting your issue. I'm wondering if you can provide the following?

  • A copy of you Vagrantfile?
  • What operating system you are using as well as the version you have currently installed.
  • Also how are you installing docker are you doing it through a custom provisioner or are you letting Vagrant install dockerfor you?
  • please login to your vagrant box containing 16.04 and provide the following output getent group | sort and getent passwd | sort

Ok, so I ran a quick test on ubuntu 16.04 and I'm not getting this error. I have feeling and I suspect you have installed a version of docker that does not contain the docker user or docker group? How are you installing docker?

Here's all the configuration that I used during my tests. If you find this information below helpful please let me now as I'm considering adding to the README.

I take bugs very seriously and hope to hear from you soon with additional information of how I can reproduce the error you are seeing.

Vagrantfile (outside of the vagrant box)

  • So this Vagrantfile will passthrough the HTTP_PROXY and HTTPS_PROXY env vars to vagrant-proxyconf if configured as global variables in your environment prior to running vagrant up or vagrant provision.

There is also a fall back instead if you would rather set the global vars in your vagrant file $PROXY_HOST and $PROXY_PORT

ENV['HTTP_PROXY']  = ENV.fetch('HTTP_PROXY',  "http://#{$PROXY_HOST}:#{$PROXY_PORT}")
ENV['HTTPS_PROXY'] = ENV.fetch('HTTPS_PROXY', "http://#{$PROXY_HOST}:#{$PROXY_PORT}")
ENV['NO_PROXY']    = ENV.fetch('NO_PROXY',    '127.0.0.1')

puts "HTTP_PROXY  = '#{ENV["HTTP_PROXY"]}'"
puts "HTTPS_PROXY = '#{ENV["HTTPS_PROXY"]}'"
puts "NO_PROXY    = '#{ENV["NO_PROXY"]}'"

puts "is vagrant-proxyconf installed? #{Vagrant.has_plugin?('vagrant-proxyconf')}"

I don't use the vagrant user, I use the deploy user. Is that my problem?
Everything works fine the first time I run vagrant up but after it installs Docker if produces the error when it finalizes and tries to configure docker when it finishes the playbook.

Here is my vagrant file:

Vagrant.configure("2") do |config|
  config.vm.box = "babigtonicus/ubuntu1604-cis-20200820"
  config.ssh.username = "deploy"
  config.ssh.private_key_path = "~/.ssh/deploy.pem"
  config.vm.provider "virtualbox"
  config.vm.hostname = "cmsp-vagrant-host"
  config.vm.box_check_update = false
  config.ssh.forward_agent = true
  config.vm.network "private_network", ip: "192.168.35.10", auto_config: true
  config.proxy.http = "http://user:password@10.10.10.10:80"
  config.proxy.https = "http://user:password@10.10.10.10:80"
  config.proxy.no_proxy = "localhost,x.x.x.x"

  config.vm.provider "virtualbox" do |v|
  	v.gui = false
  	v.memory = 1024
  	v.cpus = 1
  	v.name = "cmsp-vagrant-host"
  end

  #Run ansible from the vagrant host (not the guest)
  config.vm.provision "ansible" do |ansible|
  	ansible.playbook = "cmsp-app.yml"
    ansible.config_file = "../../ansible.cfg"
    ansible.extra_vars = "secrets.yml"
    ansible.groups = { "development" => ["default"]}
  end
end

hi @adespain - Ahh, I had a hunch the vagrant user didn't exist your vagrant box. You need to ensure that you have the vagrant user as well as the docker group for this plugin to work.

adespain commented

Ok thank you! It worked in previous versions of proxyconf so something must have changed recently?

codylane commented

You are welcome. Glad to hear that this worked. As for how it used to work, I'm afraid I don't work for Hashicorp and I am not sure how or why that might have worked for you in the past. Here's a copy of Vagrant's Changelog, perhaps there is something in here that might provide a hint.

That said, since this't a bug, I'm going to close this PR. Have a good weekend

codylane commented

I think I see what you are saying now. So there was an outstanding bug for the docker client. We did change perms on the docker client from root to vagrant to solve a larger issue a while back. Perhaps we need to think about this a bit more but most folks probably don't override the provision user so im not sure if its worth a refactor. I will keep this in mind however as we move forward.

Thanks again. Stay safe and healthy.
