Ansible Role: Pulse

Install and configure Pulse - a lightweight status page. The role runs Pulse as a Docker container using host networking.

Dependencies

• docker role (installs Docker).
• traefik role (reverse proxy).

Both are executed before this role by playbook.yaml.

Variables

This role has no defaults/main.yaml. It only uses the global variable below, which must be set in the inventory or group_vars.

Variable	Required	Default	Description
timezone	Yes	none	Global timezone, passed as TZ to the container

Example

timezone: "Europe/Amsterdam"

Usage

Run the role through Semaphore using playbook.yaml. The playbook first runs ansible-galaxy install -f -r roles/requirements.yml on localhost, then executes the docker, traefik and pulse roles.

Operational notes

• Data is stored in /mnt/pulse/data (mounted at /data in the container).
• Container pulse uses network_mode: host and sets CONNECTION_TIMEOUT to 60; the image tag is pinned in the task.
• After the container is started the role prunes unused Docker containers, images, networks and volumes.
