configWorkerContainerEnv {DockerParallel}

Configurate the worker container environment

Description

Configurate the worker container environment. Developers can use this function to set the server Ip, password and etc. via the container environment variable. The server info can be found by the getter function with the prefix .getServer (e.g. .getServerPassword(cluster)). Depending on the network status, the worker can use the server private IP to connect with the server. The developer must calls container$copy() before setting the server environment. The user provided environment variables should be respected and overwritten only when necessary. There is no default method for this generic.
