This is a container logger module for Mesos that redirects container logs to the systemd journal, or "journald".
Messages written to the container's standard output are logged using the
LOG_INFO, and standard error messages are logged using
the priority level
If the environment variable
MESOS_TASK_ID is defined its value will be
used as the program identifier in the log messages. This is mostly useful
if Marathon is used to launch the tasks.
You (or the user running the tests) need to to have access to the systemd
journal, or they will fail. Access is usually granted to members of the
systemd-journal group. To add jenkins to this group, for example:
$ usermod -a -G systemd-journal jenkins
Normal users may need to login again, and you may need to restart services such as jenkins, for the group changes to be applied.
