What docker fluentd does this command line mean?

I am studying docker fluentd. That is what I do not understand.

-v $(pwd)/fluent.conf:/fluentd/etc/fluent.conf \ 
-e FLUENT_CONF=fluent.conf \

I don't get the meaning of commands.

Solution

  • -v represents volume which means you are mounting (attaching) a file from the host file system to the internal docker file system.

    -e represents environment which is simply setting the FLUENT_CONF variable to fluent.conf which you mounted from your host file system with the -v argument.

    In that case in order to change configuration you'll have to edit the file fluent.conf which resides on the same directory you're running this command from and possibly relaunch the container (either restart or recreate it).
