Optima Config Server¶

Spring Cloud Config provides server-side and client-side support for externalized configuration in a distributed system.

Integration with existing modules - Optima Gateway and Admin Console¶

We've successfully integrated config server with existing modules and we can try to look at 
the configurations - based upon the application, profile and label:

curl <config-server-uri>/<application-name>/<profile>/<label>

Validating externalized configurations - config server instance available on DEV¶

curl https://optima-dev-tenants.optumrx.com/config/admin-console/local/master

OR

curl https://optima-dev-tenants.optumrx.com/config/admin-console/local

Validating externalized configurations - config server running on localhost¶

curl http://localhost:8888/config/local/master

OR

curl http://localhost:8888/config/local

Environment variables : running a local instance for config server¶

GIT_USERNAME:                   <Github user with access to Optima Configurations>
GIT_PASSWORD:                   <Github personalized access token for a user with access to Optima Configurations>
OPTIMA_CONFIG_SERVER_USERNAME:  <Username for a client to access the config server>
OPTIMA_CONFIG_SERVER_PASSWORD:  <Password for a client to access the config server>

Search Paths: implementation for various modules within config server¶

search-paths: '{application}'
where:
application = application-name specified for any specific application module
e.g. gateway-v2, gateway-v3 or admin-console

Base directory: used by the spring cloud config to clone the configurations¶

/tmp/config - is the directory available at root location used by the config server
               to perform a clone for the externalized configurations before injecting them 
               to client applications
