Redis
Description
This Ansible role provides a Jinja2 snippet to inject a Redis service definition into your Docker Compose setup. It renders a service.yml.j2 template that defines a redis container with sensible defaults.
Overview
The role’s service.yml.j2 template includes:
-
An Alpine-based Redis image (
redis:alpine) -
Container naming based on
application_id(defaults toredis) -
Restart policy
-
Journald logging driver
-
A named volume (
redis:/data) for persistence -
A basic healthcheck using
redis-cli ping -
Attachment to the default network
