This entry point script expects certain env variables
* COMMAND_NAME (optional, defaults to qontract-reconcile)
an entry point as defined in setup.py must be a click.Command
* INTEGRATION_NAME
used as name for the subcommand for command if present as a subcommand
on the click command
* INTEGRATION_EXTRA_ARGS (optional)
space separated list of arguments that will be passed to the command
or subcommand
* CONFIG
path to the config toml file
* LOG_FILE
path for the logfile to write to
* DRY_RUN (optional)
this is not a boolean but must contain the actual dry-run flag value,
so --dry-run or --no-dry-run
* RUN_ONCE (optional)
if 'true', execute the integration once and exit
otherwise run the integration in a loop controlled by SLEEP_DURATION_SECS
and SLEEP_ON_ERROR
* SLEEP_DURATION_SECS (default 600)
amount of seconds to sleep between successful integration runs
* SLEEP_ON_ERROR (default 10)
amount of seconds to sleep before another integration run is started
Based on those variables, the following command will be executed
$COMMAND --config $CONFIG $DRY_RUN $INTEGRATION_NAME \
$INTEGRATION_EXTRA_ARGS
