Error running postgresql96-setup initdb with Ansible - postgresql

Question

I am trying to automate the installation of a PostgreSQL database using Ansible.
However, the following task:
- name: Initialize Postgres
command: /usr/pgsql-9.6/bin/postgresql96-setup initdb
become: true
Results in this error:
fatal: [nexus-staging.chop.edu]: FAILED! => {
"changed": true,
"cmd": "/usr/pgsql-9.6/bin/postgresql96-setup initdb",

"stdout_lines": [
"Initializing database ... failed, see /var/lib/pgsql/9.6/initdb.log"
],
"warnings": []
}
The error in /var/lib/pgsql/9.6/initdb.log is:
/usr/pgsql-9.6/bin/postgresql96-setup: line 140: runuser: command not found
What is interesting is that if I run sudo /usr/pgsql-9.6/bin/postgresql96-setup initdb on the host, it runs successfully...
Any help would be appreciated.

Try with PATH environment variable defined explicitly in the task:
- name: Initialize Postgres
command: /usr/pgsql-9.6/bin/postgresql96-setup initdb
environment:
PATH: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
become: true
Most likely the value of the path is set differently for interactive and non-interactive shell sessions.
Or locate the runuser executable and add the path before running the script:
command: PATH=/runuser/location:${PATH} /usr/pgsql-9.6/bin/postgresql96-setup initdb
