[Elastic Agent] Add ability to communicate with Kibana through service token #28096

blakerouse · 2021-09-23T13:05:45Z

What does this PR do?

Adds ability for the libbeat Kibana client to communicate with Kibana using an ES service token. This is used by the container sub-command with the KIBANA_FLEET_SERVICE_TOKEN environment variable to communicate with Kibana using the provided ES service token.

Why is it important?

This allows a spawned container of Elastic Agent that will bootstrap Fleet in Kibana to use a service token instead of using a username/password authenticated super user.

As it is the fleet-server service toke, should we indicate this here by calling it KIBANA_FLEET_SERVER_SERVICE_TOKEN ?

It doesn't have to be a Fleet Server token, it could be any token that has the correct permissions. It could be a different token then the one provided to Fleet Server.

I think its best to keep the name KIBANA_FLEET_SERVICE_TOKEN because KIBANA_FLEET_{name} is the same for all other environment variables that control Elastic Agent containers communication to Kibana.

It also matches with the configuration that can be used:

kibana: fleet: service_token: abc123

@joshdover Do we check on the Fleet side if it is a fleet-server service token or if it has the correct permissions?

We'll be checking that is has correct permissions, so it technically doesn't have to be the elastic/fleet-server service token. It just needs to have the "application privilege" that is being granted to the service account by default as defined in this issue: elastic/kibana#112647

So by default, Kibana would accept the elastic/fleet-server service account's token or any credentials for a super user (basic, apikey, etc.)

@joshdover @blakerouse As soon as all components are in place in the different projects it would be good to have an e2e test confirm that this works as expected end to end.

@joshdover @blakerouse As soon as all components are in place in the different projects it would be good to have an e2e test confirm that this works as expected end to end.

I filed an issue to track it - elastic/e2e-testing#1613

…lity to pass service token to container subcommand.

jlind23 · 2021-10-07T08:43:47Z

@blakerouse anything missing in this PR apart of the e2e test?

joshdover

Changes LGTM and I have been able to verify this works against elastic/kibana#113932

blakerouse · 2021-10-11T15:59:34Z

@jlind23 No was waiting on confirmation that it worked from @joshdover. Now that I know it works, I will work on getting it merged.

None of the issues seem to be related to the PR. Looks like unrelated changes that are in master or an issue with the Windows 8 CI runner. Going to merge.
