Example Playbook

This example is taken from molecule/default/converge.yml and is tested on each push, pull request and release.

---
- name: Converge
  hosts: all
  become: true
  gather_facts: true

  pre_tasks:
    - name: Read token from remote machine
      ansible.builtin.slurp:

      register: token_raw

  roles:
    - role: robertdebock.vault_snapshot
      vault_snapshot_token: "{{ token_raw['content'] | b64decode }}"

The machine needs to be prepared. In CI this is done using molecule/default/prepare.yml:

---
- name: Prepare
  hosts: all
  become: true
  gather_facts: false

  roles:
    - role: robertdebock.bootstrap
    - role: robertdebock.core_dependencies
    - role: robertdebock.hashicorp
    - role: robertdebock.vault
      vault_type: ent
      vault_hardening_disable_swap: false
    - role: robertdebock.vault_configuration
      vault_configuration_license: "{{ lookup('ansible.builtin.env', 'VAULT_LICENSE') }}"
      vault_configuration_listener_tcp:
        address: "127.0.0.1:8200"
        cluster_address: "127.0.0.1:8201"
        tls_disable: true
      vault_configuration_storage_raft:
        path: "/opt/vault/data"
        node_id: "{{ ansible_hostname }}"

  tasks:
    - name: Flush handlers
      ansible.builtin.meta: flush_handlers

    - name: Start Vault
      ansible.builtin.service:
        name: vault
        state: started

    - name: Initialize Vault
      ansible.builtin.command:
        cmd: vault operator init -format=yaml
      register: vault_init_raw
      environment:
        VAULT_ADDR: "https://localhost:8200"
        VAULT_SKIP_VERIFY: "true"
      changed_when: true

    - name: Store vault_init_raw output as YAML
      ansible.builtin.set_fact:
        vault_init: "{{ vault_init_raw.stdout | from_yaml }}"

    - name: Store root_token
      ansible.builtin.copy:
        content: "{{ vault_init.root_token }}"
        dest: /root/.vault-token
        owner: root
        group: root
        mode: "0640"

    - name: Unseal Vault
      ansible.builtin.command:
        cmd: vault operator unseal {{ item }}
      loop: "{{ vault_init.unseal_keys_b64 }}"
      environment:
