Shell environment variables in vagrant files are o

Question

I'm running Vagrant 1.8.5, which supports environment variables in the Vagrantfile at provisioning time using a format like this

config.vm.provision :shell, path: "bootstrap.sh", env: {"MYSQL_DB_USERNAME"=>"django", "MYSQL_DB_PASSWORD"=>"supersecretpasswordwasreplaced"}

However, I would like these environment variables to also be available when I do up without provisioning, or when I SSH into the server to do jobs. The obvious ways I can find are

• to have them built into the box (seems like overkill) or
• repeat them in my config.ssh.forward_env so that they are available to both the provisioner and SSH.

Is there a better way?

Answer 1

I am not sure about the best ultimate way - I've seen this question popping from time to time and discussion.

repeat them in my config.ssh.forward_env so that they are available to both the provisioner and SSH.

well, it could sound like a good solution but there's some drawback, I've discussed in this question already

Personally when I need to set env variable, I would add them in the .profile file:

  config.vm.provision "shell", privileged: false, inline: <<-SHELL
    echo "export MYSQL_DB_USERNAME = django" > /home/vagrant/.profile
    echo "export MYSQL_DB_PASSWORD = supersecretpasswordwasreplaced" > /home/vagrant/.profile
  SHELL

They will be available when you login.

At first glance, this answer seems similar to the top voted answer. However, please look carefully at the redirection operator on the second echo

config.vm.provision "shell", env: {"DOCKERHUBID"=>ENV['DOCKERHUBID'], "DOCKERHUBPASS"=>ENV['DOCKERHUBPASS']}, inline: <<-SHELL
echo "export DOCKERHUBID=$DOCKERHUBID" > /home/vagrant/.profile
echo "export DOCKERHUBPASS=$DOCKERHUBPASS" >> /home/vagrant/.profile
SHELL
