Configuration and command-line arguments

Configuration and command-line

The ew-vod2cbm global service parameters can be specified in the following ways:

  1. On the command-line
  2. As environment variables
  3. In the configuration file (when specified by the command-line)
  4. Default values

This also shows the order of precedence from top to bottom, where values on the command-line will override all other values.

The global service parameters cannot change during execution, except for logging.

An example configuration file is available in Example Configuration.

Note that the typical way of creating and configuring channels and assets is over the REST API. It is also possible to configure assets and channels in the configuration file. This can be handy mostly for testing. A channel parameter, when present, will override the corresponding global parameter. For example the global parameter defaultMaxliveWin would be overridden by the channel parameter maxLiveWindowS.

The command-line

All command line parameters and environment variables can be seen by running:

ew-vod2cbm -h
