Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

  - hosts: localhost
    remote_user: root
    vars:
      clickhouse_users_custom:
          - { name: "testuser",
              password_sha256_hex: "f2ca1bb6c7e907d06dafe4687e579fce76b37e4e93b7605022da52e6ccc26fd2",
              networks: "{{ clickhouse_networks_default }}",
              profile: "default",
              quota: "default",
              dbs: [ testu1 ] ,
              comment: "classic user with plain password"}
          - { name: "testuser2",
              password: "testplpassword",
              networks: "{{ clickhouse_networks_default }}",
              profile: "default",
              quota: "default",
              dbs: [ testu2 ] ,
              comment: "classic user with hex password"}
          - { name: "testuser3",
              password: "testplpassword",
              networks: { 192.168.0.0/24, 10.0.0.0/8 },
              profile: "default",
              quota: "default",
              dbs: [ testu1,testu2,testu3 ] ,
              comment: "classic user with multi dbs and multi-custom network allow password"}
      clickhouse_dbs_custom:
         - { name: testu1 }
