configure-dana-dev

The purpose of this repository is to take a new Red Hat Enterprise Linux-based VM and turn it into a dana-dev-x VM using an Ansible playbook.

Getting Started

Prerequisites

  • A local machine with Ansible installed.
  • This was tested on a Red Hat Enterprise Linux 8.7 VM with the following version of Ansible installed:
ansible [core 2.13.3]
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/dana/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.9/site-packages/ansible
  ansible collection location = /home/dana/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/bin/ansible
  python version = 3.9.13 (main, Nov  9 2022, 13:16:24) [GCC 8.5.0 20210514 (Red Hat 8.5.0-15)]
  jinja version = 3.1.2
  libyaml = True
  • A Virtual Machine (on Azure for example) with OS Disk space of 256GB. Note it may be needed to extend the root partition for the playbook to run successfully, as explained here.
  • SSH passwords to the VMs you'd like to configure.

Steps

  • In order to run the playbook, clone it to your local machine:
$ git clone https://github.com/dana-team/configure-dana-dev.git
$ cd configure-dana-dev
  • Edit the inventory.ini file to include the VMs you want to configure.
  • Establish SSH connection between your local host and the VMs you want to configure:
$ ssh-keygen
$ ssh-copy-id <user>@<remote-vm>
  • Test the SSH connection works correctly:
$ ansible -m ping all -i inventory.ini

dana-dev-x.westeurope.cloudapp.azure.com | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}

Configure

  • Run the playbook:
$ ansible-playbook configure-vm.yml -i inventory.ini --ask-vault-pass
  • The Ansible Vault Password exists as a repository secret in this repo (Settings -> Secrets - > Repository secrets).

Unconfigure

  • Run the playbook:
$ ansible-playbook unconfigure-vm.yml -i inventory.ini

What gets configured

  • The configure-vm.yml/unconfigure-vm.yml playbooks do the following:
    1. Register/Unregister the VM to a Red Hat subscription and enables other repos.
    2. Intsall/Uninstall DNF packages.
    3. Intsall/Uninstall certain dev tools.
    4. Install/Uninstall GoLand.

How to add/remove things

  • Edit the group_vars/dana-dev-vms.yml file to add/remove packages, change versions, etc...
