Installation#

$ dnf install ansible

Configuration#

The main configuration is stored in /etc/ansible/ansible.cfg, for example.

#inventory      = /etc/ansible/hosts
#inventory_plugins  = /usr/share/ansible/plugins/inventory

[inventory]
#enable_plugins = host_list, virtualbox, yaml, constructed

Inventory#

The inventory configuration is stored in /etc/ansible/hosts, for example:

[local]
127.0.0.1

[containers]
container ansible_connection=docker

To test the connection to the machines:

$ ansible -i hosts containers -m ping

Docker machines can be configured in docker_machine.yml, for example:

plugin: community.docker.docker_machine
strict: no
keyed_groups:
  - separator: ''
    key: docker_machine_node_attributes.DriverName
strict: no
keyed_groups:
  - prefix: tag
    key: 'dm_tags'
compose:
  ansible_ssh_common_args: '"-o StrictHostKeyChecking=accept-new"'

Tasks#

To run a task:

$ ansible -i hosts local -m ping

Playbooks#

Create a playbook file (e.g. playbook.yml):

- hosts: local
  tasks:
  - name: Ping
    ping:

To run the playbook:

$ ansible-playbook -i hosts playbook.yml

Platform-specific Notes#

On RHEL 8, all ansible-playbook commands will need to specify the following variable:

-e ansible_python_interpreter=/usr/libexec/platform-python

Docker#

$ ansible-galaxy collection install community.docke

Examples#

See cipherboy/ansible-vms.

To run the script:

$ ansible-playbook -i hosts ansible-vms/pki-server.yml
