How to: Set defaults on deployit.conf in Deploy

Question

1. How can we set defaults on deployit.conf ? (Example server.hostname)
2. How can we set akka.io.dns default value (in xl-deploy.conf ?)

Answer

1. From Deploy 10.3 and later, the deploy.server.hostname and deploy.server.port properties from the deploy-server.yaml file are moved to deployit.conf file and renamed as server.hostname and server.port respectively.

2. This should be also added in the deploy-server.yaml. Hostname resolution between masters and workers is based on DNS lookups. This means localhost and other /etc/hosts-based lookups will fail by default. Although using localhost is considered bad practice, if your installation relies on it you can reinstate the behavior by including a setting akka.io.dns.resolver = inet-address in deploy-server.yaml.
