Include Hostname in Container name

22 votes

The container agent plugins for Docker and Podman should have a configurable option to include the hostname in the container name for the piggyback data sections.
Often users have multiple Docker nodes running containers with the same name (e.g. nginx). Piggyback data cannot be separated with only the container name in this case.

It would also be useful if in this case the host name was also automatically entered as the parent for the container host.

Perhaps this could be implemented more generally in the DCD itself. There you could add a hostname translation option where the piggyback host could be inserted as a $hostname$ or $fqdn$ macro:

[ container_(.*)] -> [$PB_HOSTNAME$_\1] -> container_App => MyHost1_App, MyHost2_App, ...
[ container_(.*)] -> [$PB_FQDN$_\1] -> container_App => MyHost1.domain.de_App, MyHost2.domain.de_App,...

This could be used for all DCD cases without the need for an additional hostname translation rule (which also does not currently support macros).

The parent property could be something the DCD would set.
