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.
