saltbox_mod

Environment for managing custom Ansible roles within a Saltbox host.

Installation

sb install saltbox-mod

Alternatively:

git clone https://github.com/saltyorg/saltbox_mod.git /opt/saltbox_mod

Usage

From Scratch

1. Create folders for the Ansible role:

   mkdir -p /opt/saltbox_mod/roles/newrole/{defaults,tasks}

2. Place the defaults and tasks files in there:

   touch /opt/saltbox_mod/roles/newrole/{defaults,tasks}/main.yml

3. Code your role by adding variables and tasks to the respective files.

4. (Legacy*) Optionally, add custom variables into settings.yml:

   /opt/saltbox_mod/settings.yml

   * Use of the Inventory system is now preferred over this method.

5. Add the Ansible role and tags to the saltbox_mod.yml playbook:

   To edit:

   $EDITOR /opt/saltbox_mod/saltbox_mod.yml

   Add the following line in the appropriate section under roles::

       - { role: newrole, tags: ['newrole'] }

   Final result:

   ---
   - hosts: localhost
     module_defaults:
       ansible.builtin.setup:
         fact_path: "/srv/git/saltbox/ansible_facts.d"
     vars_files:
       - settings.yml
       - ['/srv/git/saltbox/accounts.yml', '/srv/git/saltbox/defaults/accounts.yml.default']
       - ['/srv/git/saltbox/settings.yml', '/srv/git/saltbox/defaults/settings.yml.default']
       - ['/srv/git/saltbox/adv_settings.yml', '/srv/git/saltbox/defaults/adv_settings.yml.default']
     roles:
       # Reqs
       - { role: pre_tasks, tags: ['always', 'pre_tasks'] }
       # Apps Start
       - { role: helloworld, tags: ['helloworld'] }
       - { role: myrole, tags: ['myrole'] }
       - { role: newrole, tags: ['newrole'] }
       # Apps End

   Caution: The pre_tasks role is required and should not be removed.

6. Deploy the Ansible role:

   sb install mod-newrole

   Alternatively :

   sudo ansible-playbook saltbox_mod.yml --tags newrole

---

From an Existing Role

Steps 1 to 3 can be simplified by using the helloworld role as a template. It should be usable without too much modification for most web apps that use a single web port.

cp -r /opt/saltbox_mod/roles/helloworld /opt/saltbox_mod/roles/newrole && \
sed -i 's/helloworld/newrole/g' /opt/saltbox_mod/roles/newrole/*/main.yml

Then edit the defaults settings:

$EDITOR /opt/saltbox_mod/roles/newrole/defaults/main.yml

At the very minimum, you may expect to have to update the following variables:

newrole_web_port:
newrole_docker_image:
newrole_docker_envs_default:
newrole_docker_volumes_default:

Proceed to step 4.
