pytroll-runner

The pytroll runner is a generic runner that allows to automate third party software in a pytroll environment. The runner is listening for pytroll messages and running a user provided command on the files mentioned in the received message. When the command had run, the resulting files are published as pytroll messages. The published messages will contain metadata from the input message (except for uris and uids).

To start the runner: pytroll-runner config.yaml

The configuration file

The configuration file is made of three sections.

script

A dictionary with:

• command Full path script to run
• optionally workers The number of workers to use for parallel processing of messages. Defaults to 1.

subscriber_config

The configuration of the subscriber. The contents of this section are passed directly to posstroll's create_subscriber_from_dict.

publisher_config

This section contains settings on how to publish messages.

expected_files

The glob pattern of files to be expected when the script is run. Beware that any files with matching filenames will be included in the list, and that could include files from previous runs.

static_metadata

Metadata to include in the published messages.

publisher_settings

The configuration for the publisher. The contents of this sections are passed directly to posttroll's create_publisher_from_dict.
