config_merger

Config Merger

This component validates and combines two or more config proto files into a single TestGrid configuration (also a config proto). This config is used by basically every other component in TestGrid.

Local development

Configuration List

The config merger requires a YAML file containing:

• a list of the configurations its trying to merge
• a location to put the final configuration

The --config-list flag should point to a file like this:

target: "gs://path/to/write/config"         # Final result goes here
sources:
- name: "red"                               # Used in renaming
  location: "gs://example/red-team/config"  
  contact: "red-admin@example.com"          # Used for cross-team communication, not yet by config_merger
- name: "blue"
  location: "gs://example/blue-team/config"
  contact: "blue.team.contact@example.com"

Renaming

Test Groups, Dashboards, and Dashboard Groups may be renamed to prevent duplicates in the final config. In this case, the name in the config list is added as a prefix, giving precedence by alphabetical order.

For example, if both configurations in the example above contain a dashboard named "foo", the red dashboard will be renamed to "red-foo".
