Alpaca Eureka Configuration

This guide details all configurations that are available within the Alpaca Eureka. All configurations can be used in the application-prod.yml file located in the /etc/alpaca/eureka/config.

Any changes made while Eureka is running will not take effect until after a restart. Use the following command to restart Eureka - service alpaca-eureka restart.

YAML (YAML Ain't Markup Language)

All Alpaca configurations are in the YAML (.yml) format.

Basic Rules

• YAML is case sensitive.
• YAML does not allow the use of tabs. Spaces are used instead as tabs are not universally supported.

• A dictionary is represented in a simple key: value form (the colon must be followed by a space):

      alpaca:
          migration:
            announcementRepositoryUsername: "BoNjOuRlEsAmIs049"
            announcementRepositoryPassword: "viveLEROILouis14"
            htmlEncodeExports: true
  

• All members of a list are lines beginning at the same indentation level starting with a - (a dash and a space):

    broadworks:
      profileServer:
      - cluster: Production
        fileRepo: ProfileServer
        username: fileadmin
        password: P@ssw0rd
      - cluster: Lab
        fileRepo: ProfileServer
        username: fileadmin
        password: P@ssw0rd
  

• Comments are denoted by #.

    # Alpaca Configuration
    alpaca:
        # Migration Configuration
        migration:
          announcementRepositoryUsername: "BoNjOuRlEsAmIs049"
          announcementRepositoryPassword: "viveLEROILouis14"
          htmlEncodeExports: true

Example Configuration

This sample configuration is meant as a guide only. Do not copy and paste the entire content into your configuration.

server:
  port: 8761
eureka:
  instance:
    hostname: alpaca-1.lab.ecg.co
  client:
    registerWithEureka: true
    fetchRegistry: false
logging:
  file:
    path: /var/log/alpaca

Server (server)

• port: The TCP port on which to run the Eureka server.

Eureka (eureka)

• instance.hostname: This is a comma separated list of additional Eureka URLs to register with. This allows clustering of Eureka nodes for service discovery.
• client.registerWithEureka - Indicates whether or not this instance should register its information with eureka server for discovery by others. This defaults to true.
• client.fetchRegistry - Controls whether or not this client is going to try to connect to the Eureka server(s) in order to download the information on other services' endpoint. It can do so without registering itself. Defaults to false.

Logging (logging)

• file.path: The location to write the gateway log. This defaults to /var/log/alpaca. Rotation and file naming are configured in the logback-spring.xml file.
