• https://docs.ansible.com/ansible/intro_installation.html
• version should be >=2.2.0.0

• ansible-galaxy install -r requirements.yml

• If your local username does not match your ssh account name on the server, configure that account name in your ~/.ssh/config

  Host bla.dlang.org
      User accountname
  

• Each container runs it's own sshd server which can be accessed by proxing through the host. The following setting in your ~/.ssh/config is recommended so that you can e.g. run ssh nightlies.builds.dlang.io.

  Host *.*.lxd
     User root
     ProxyCommand ssh -W %h:%p $(echo %h | cut -d. -f2).dlang.io
  

For less typing store vault, sudo, and profitbricks passwords in Pass: The Standard Unix Password Manager.

pass add dlangci/ansible_vault
pass add dlangci/sudo

At best also tell git how to diff encrypted files.

git config diff.ansible-vault.textconv 'ansible-vault view --vault-password-file=ansible/query_vault_pass.sh'

Alternatively comment out vault_password_file in ansible.cfg and ansible_become_pass in group_vars/all and pass -K, --ask-become-pass and --ask-vault-pass to ansible-playbook.

• remove host facts caches under .cache/ in case major properties (e.g. IP address, hostname) change

• assuming initial account created during installation (using your commong username and sudo password, also see roles/users)
• ssh-copy-id server.dlang.io
• ansible -m raw -a 'apt-get update -q=2' server.dlang.io
• ansible -m raw -a 'apt-get install --no-install-recommends python-minimal python-apt -q=2' server.dlang.io
• ansible -m ping server.dlang.io # test access

• Download - Vagrant

• see comment in Vagrantfile for an example of system-wide ~/.vagrant.d/Vagrantfile VirtualBox defaults

• vagrant commands

  • vagrant up ci
  • vagrant halt ci
  • vagrant destroy ci
  • vagrant provision ci # rerun ansible
