docker specifics
----------------
This page talks about docker, as this is the platform the rsyslog
team has hands-on experience with. Some or all of the information
might also apply to other solutions.
Potential Trouble causes:
- container terminate timeout
By default, a docker container has 10 seconds to shut down. If rsyslog
is running with a large queue that needs to be persisted to disk,
that amount of time might be insufficient. This can lead to a hard
kill of rsyslog and potentially cause queue corruption.
- shared work directories
Shared work directories call for problems and shall be avoided. If
multiple instances use the same work directory, the may even overwrite
some files, resulting in a total mess. Each container instance should
have its own work directory.
