CONFIGURAÇÃO

Nada, que eu saiba. Vou atualizar isso se eu aprender o contrário.

SO / AMBIENTE

RESUMO

Estou no IRC há cerca de uma hora tentando resolver por que estou recebendo um erro.

Não há mais nada no meu manual além de nomes de variáveis. Isto está em um recipiente limpo e fresco. Eu posso psql -U postgres bem, então isso tem que ser algo com ansible.

PASSOS PARA REPRODUZIR

 - name: Install PostgreSQL and related packages
   apt: name={{ item }} state=present update_cache=yes
   with_items:
      - postgresql
      - postgresql-contrib
      - python-psycopg2

 - name: Create new database user
   become_user: postgres
   postgresql_user: name=apples role_attr_flags=SUPERUSER,CREATEROLE,CREATEDB,REPLICATION

RESULTADOS ESPERADOS

Para que ele acesse o banco de dados e crie um usuário.
