Templates

Ready-made applications. One step creates the project, the database it needs and its settings, and deploys it.

What is available

Umami: Website analytics without cookies.
Miniflux: A fast, minimal feed reader.
Memos: Quick notes and a personal knowledge base.
linkding: A bookmark manager.
Hasura: An instant GraphQL API over the project's Postgres database.
Grafana: Dashboards and alerts.
n8n: Workflow automation.
Uptime Kuma: Checks that your sites are up and alerts you. Keeps its data on a permanent disk.
IT Tools: Developer utilities. Needs no database.

Deploying one

Choose Templates in the sidebar, pick one and press Deploy. It asks only for what it cannot decide — usually the first administrator's password. From a terminal:

Terminal

arrah templates list
arrah templates deploy miniflux --set ADMIN_PASSWORD=...

What a template is

A public image at a fixed version, a size, and the variables it runs with. Nothing a project set up by hand could not do.
Each listed version was deployed for real before it was added.
Every template keeps its data in the project's database or on a permanent disk, so redeploying or moving to a newer version loses nothing.
Keys the application needs but nobody has to read are generated and stored encrypted. A password you type is stored the same way — keep your own copy.
To update later, change the image version in the project's settings and deploy.

Software that needs MySQL is not listed. For anything else, see Docker images.
