@fearful-symmetry I believe you have started some work to be able to embed a certificate in a configuration is there a PR?

[fearful-symmetry]

I haven't started yet--I still need a way to get a certificate file onto an otherwise inaccessible docker plugin.

Keep @michalpristas and I in the loop, this feature might be required by the agent later.

There's libbeat changes we would need to deal with a string instead of path, right? I'll bump it up my priority list.

[ph]

no need to bump it in priority, it's not a blocker for us.

Yes most of the changes would be in the libbeat, better to create an official proposal.
There a few issues in beats talking about it.
