make features and flavors configurable

evgeni · evgeni · commit 80d53f0ff327 · 2025-12-02T11:10:32.000+01:00
This PR introduces two new concepts: `flavor`s and `feature`s.

A feature is an abstract representation of "the deployed system can now do X", usually implemented by enabling a Foreman/Pulp/Hammer plugin (or a collection of these).

A flavor is a set of features that are enabled by default and can not be disabled. This is to allow our common deployment types like "vanilla foreman", "katello", "satellite" and similar.

The idea is to allow people to select a baseline using `--flavor` and then further adjust it to their liking using `--feature` and the code then figures out what foreman/hammer/pulp plugin (or combination of these) needs to be enabled for that.

+### Features and Flavors
+
+To allow deployments with different sets of functionality enabled, the deployment utility supports features and flavors.
+
+- A feature is an abstract representation of "the deployed system can now do X", usually implemented by enabling a Foreman/Pulp/Hammer plugin (or a collection of these). 
+- A flavor is a set of features that are enabled by default and can not be disabled. This is to allow common deployment types like "vanilla foreman", "katello", "satellite" and similar.
+
+Additionally to the functionality offered by plugins, we define the following "base" features:
+- `foreman` to deploy the main Rails app and make the deployment a "Server"
+- `foreman-proxy` to deploy the Foreman Proxy code
+- `hammer` to deploy the base CLI
+
+These base features control which plugins are enabled when a feature is requested.
+- `foreman` + `remote_execution` = `foreman_remote_execution`
+- `foreman-proxy` + `remote_execution` = `smart_proxy_remote_execution_ssh`
+- `hammer` + `remote_execution` = `hammer_cli_foreman_remote_execution`
+
+A deployment can have multiple base features enabled.
+
 ### Authenticated Registry Handling
 
 In the non-default case where the image sources are supplied from an authenticated location users will need to inject a login step.
