Late last year we introduced the
Rancher Catalog
13
- Exposes Docker
Compose
Templates stored in
GitHub
- Started with a set of
public templates for
common services
- Allows configuration
and deployment of
stacks
- Supports versioning
and upgrades
- Just added support
for private catalogs

Start With Containers
• Look upstream first!
(reuse, reuse, reuse)
• What tools are
needed.
• Data layout, health
checks and
configuration.

Organize into Services
• Services have many
parts.
• Keep each
container focused
on one thing.
• Remember to share!

Parameterize!
• What does the end
user NEED to know
to configure the app.
• What can be a
reasonable default.
