Ansible-Role "ansible_lza_install_common"

Description

This role provides all necessary post-install tasks to setup a basic multi-purpose Debian VM.

Prerequisites

To use this role, the following software must be installed on your workstation:

• ansible

To deploy this role to a managed host, the following software must be installed on the target:

• Python3
• SSHd

It is recommended to use Debian VMs as deployed by SLUB's UDA tool with this role. Otherwise you will not have access to the software packages that are located in SLUB's private Debian package repository.

Quick Start

	ansible-playbook site.yml [-i <INVENTORY_FILE>] [--limit <HOSTNAME>] [-u <USERNAME>] [-b]

General Ansible usage

Most options already have sensible defaults in ansible.cfg. However, you can override these defaults using CLI options/flags if you want to.

To simply run the playbook, just call the site.yml playbook like this:

	ansible-playbook site.yml -u <username>

If you want to limit the execution to a subset of all hosts that are listed in the inventory, use the -l or --limit option like this:

	ansible-playbook site.yml -l <hostna*>
	ansible-playbook site.yml -l <hostname>
	ansible-playbook site.yml -l <hostname1>:<hostname2>:...
	ansible-playbook site.yml -l <inventory_group>
	ansible-playbook site.yml --limit=<hostna*>

If you do not have Vault password files in the directory above the role direcory, you have to give the Vault password before execution:

	ansible-playbook site.yml --ask-vault-pass

You can use your own inventory file by adding the -i or --inventory=INVENTORY option:

	ansible-playbook site.yml -i inventory.yml
	ansible-playbook site.yml --inventory=inventory.yml

Tasks in this role have been tagged to enable users to only run subsets of tasks. This can be leveraged to decrease run times or run only certain tasks after small changes. To list all available tags, use:

	ansible-playbook site.yml --list-tags

You can then run only certain tagged tasks by using the --tags option:

	ansible-playbook site.yml -t tag1,tag2,...,tagN
	ansible-playbook site.yml --tags=tag1,tag2,...,tagN

For more help with ansible-playbook, use the --help flag.

Testing the role

Tests have been implemented using the Molecule framework. The details on using the test suite are described below molecule/.

Variables

Many variables have been "hidden" in encrypted Ansible Vaults. For security reasons, these Vaults are maintained in a separate private internal repository of SLUB's Git. However, in order to better understand the data within the vaults, you can find \*.vault.example files below the vars/ directory.

If you work outside of SLUBArchive and have no access to the vault repository, make sure to put the necessary vaults in the expected paths at ../ansible_vaults/<ROLENAME>/.

git configuration

Just run the setup_gitconfig.sh script that comes with the repo to correctly setup all necessary local Git configurations.
