The force-push was to rebase onto current master for your convenience. 😉 👍

thanks for the contribution.

Why libjemalloc-dev ?

[wfernandes]

@edsiper It was added as a dependency earlier on. We added it to the Dockerfile because the docker image wouldn't build without it.

I see it being added updated as part of this commit 4641443 to the project.

I troubleshoot the Jemalloc header issue, it was a problem of a directory context due to the new path of the stream processor, the fix has been pushed: 00dd804

On this case including libjemalloc-dev could generate issues since we bundle Jemalloc and likely headers can be different from the one provided in the build system v/s the bundled in Fluent Bit.

Please adjust the file Dockerfile change since it should be ok now.

thanks.

note: I've squashed and changed the commit subject to
