CONFIGURATION

Nothing, to my knowledge. I will update this if I learn otherwise.

OS / ENVIRONMENT

SUMMARY

I've been on IRC for around an hour now trying to solve why I'm getting an error.

There is nothing else in my playbook aside from variable names. This is on a clean, fresh container. I can psql -U postgres fine, so this has to be something with ansible.

STEPS TO REPRODUCE

 - 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

EXPECTED RESULTS

To have it access the database and create a user.

ACTUAL RESULTS

<postgres-dev.domain.com> ESTABLISH SSH CONNECTION FOR USER: root
<postgres-dev.domain.com> SSH: EXEC ssh -C -vvv -o ControlMaster=auto -o ControlPersist=60s -o Port=22 -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o User=root -o ConnectTimeout=10 -o ControlPath=/tmp/ansible-ssh-%h-%p-%r postgres-dev.domain.com 'LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8 LC_MESSAGES=en_US.UTF-8 /usr/bin/python'

I'm sorry I wasted your time having to read this. I was missing become: yes

For posterity, if you are creating a new db or a new user, you must become the postgres user. I was trying to do this as root and I kept getting the error. Working example below.

  - name: make events database
    postgresql_db:
      name: events
    become: true
    become_user: postgres

  - name: make www-data postgresql user
    postgresql_user:
      db: events
      name: www-data
      password: "{{ psql_password }}"
      priv: ALL
    become: true
    become_user: postgres

I am using Ansible 2.6.2 and it still does not work for me
