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 to redis)

  • Restart policy

  • Journald logging driver

  • A named volume (redis:/data) for persistence

  • A basic healthcheck using redis-cli ping

  • Attachment to the default network

Include this snippet in your top-level docker-compose.yml.j2 where you want Redis to appear.

Features

  • Configurable application_id
    Sets container name ({{ application_id }}-redis).

  • Restart policy
    Controlled by DOCKER_RESTART_POLICY.

  • Journald logging
    Ensures logs are captured by systemd’s journal.

  • Persistent storage
    Declares and mounts redis:/data.

  • Built-in healthcheck
    Uses redis-cli ping with configurable intervals and retries.
