How to restrict the JobScheduler Agent to listen to specific network interfaces when using HTTP and HTTPS

Use the environment variables SCHEDULER_HTTP_PORT and SCHEDULER_HTTPS_PORT

• It is also possible to set the HTTP and HTTPS port with command line options but we recommend to use environment variables
• For this create an instance script in which environment variables are set before the startscript is called.
  • How to create and instance script and which environment variables can be set is described in JobScheduler Universal Agent - Running multiple instances

Indicating which network interfaces should listen to when using http

• The value of the environment variable SCHEDULER_HTTP_PORT of the instance script can have the form SCHEDULER_HTTP_PORT=[ip address or hostname:]port
• If only a port is specified then the JobScheduler Agent listens to all available network interfaces.
• It is the same like SCHEDULER_HTTP_PORT=0.0.0.0:port.
• If a hostname or ip address is specified in addition then it indicates which network interfaces the JobScheduler Agent should listen to.

Indicating which network interfaces should listen to when using https

• The value of the environment variable SCHEDULER_HTTPS_PORT of the instance script can have the form SCHEDULER_HTTPS_PORT=[ip address or hostname:]port
• If only a port is specified then the JobScheduler Agent listens to all available network interfaces.
• It is the same like SCHEDULER_HTTPS_PORT=0.0.0.0:port.
• If a hostname or ip address is specified in addition then it indicates which network interfaces the JobScheduler Agent should listen to.

Requirements

• A HTTP port setting is required for the JobScheduler Agent startscript.

• It is not possible to use HTTPS only but you can bind "localhost" to the HTTP port.

  SCHEDULER_HTTP_PORT=localhost:4445
