Should there be a new issue for this? The "closes" is currently pointing to a merged PR which points to a closed issue.

This is the stack-up elasticsearch right? I'm wondering if we should have this docker-compose launch both ES and kibana. Maybe even keep it simple and run them in http mode.

For example, do we know if the certs you have here are always going to work? I'd expect new launches of e-p stack up to use new certs.

yes!

For example, do we know if the certs you have here are always going to work? I'd expect new launches of e-p stack up to use new certs.

If they change the current certs, this will stop working. I had this in mind when I used the certs. But it probably can be simplified. We just need a Kibana instance that creates logs into /tmp/service_logs. This kibana service doesn't need fleet related stuff and could connect to a new ES instance.

This kibana service doesn't need fleet related stuff and could connect to a new ES instance.

Yep, that's exactly what I'm thinking. Just keep the elastic-package service docker compose as bare-bones as we need to generate good sample logs.

I ended up trying this and it seemed to work crespocarlos#2 but I only got server logs. Is there something we should add to produce some audit logs at this stage? or maybe we can leave that until the system test stage.

Hm. Not really. Both logs should be created if enabled in kibana.yml. Let me fix the elastic-package service setup for Kibana package and I'll check why audit logs are eventually not being created.

Actually, audit logs are not generated unless you do some action with the kibana service instance.

xpack.security.enabled has to be true too.

Some review thoughts for you. I could see merging as-is and planning for more work once the test suite is more complete. Hard to validate all the corners manually.

-    if: "ctx?.user?.name != null"
+  - pipeline:
+      name: '{{ IngestPipeline "pipeline-json" }}'
+      if: |-


Might be nice to align this conditional with https://github.com/elastic/integrations/blob/main/packages/elasticsearch/data_stream/server/elasticsearch/ingest_pipeline/default.yml#L15-L17

This conditional was copied from platform-observability package. It does seem like an overkill

Or if there's a reason for it, that's fine. But it'd be good to be consistent about how we say "this is a json message"

Now looking at both approaches, here we need 4 processors in total to achieve what this does with 1. Besides, on elasticserach pipeline, apparently the document is dropped if message is not a json whereas here, the document is still ingested.

+      field: "*"
+      override: true
+  - join:
+      field: error.stack_trace


This got me thinking that it'd be good to have stack trace sample logs from kibana to make sure this is the right behavior. Maybe not for this PR though.

 ## Compatibility

-The `kibana` package works with Kibana 6.7.0 and later.
+The `kibana` package works with Kibana 8.5.0 and later.


Guessing this is a problem beyond this PR, but in trying to check the changes I noticed the formatting on these pages is all weird now.

Yeah. I've noticed this too. I'll try to find what's causing it

Oh, I think I forgot to mention this (maybe lost in the github review cycle somewhere), but I opened crespocarlos#2 for an idea at simplifying the setup here.

Aha. Thanks. ~~There's only one thing missing there. We need to reset the kibana_system user's password. It will still generate logs without that though.~~ nevermind! It works :). I'll just try to get audit logs there

I had to slightly complicate it in order to get audit logs there.

Kind of surprised audit logging would require use of a particular user, but I guess if it works it works :)

A couple visual inspection thoughts, I didn't try to run it today though.

Can do this to have it use the .env value

Suggested change

- "KIBANA_PASSWORD=changeme"

- KIBANA_PASSWORD

good catch.

I went looking at how the ES docker docs did this to see if we should copy https://github.com/elastic/elasticsearch/blob/main/docs/reference/setup/install/docker/docker-compose.yml#L55-L56

But I think I like your rendition better :)

It looks like the audit logs are not produced. Maybe that is caused by my local docker version but I got the following logs:

setup.sh:

{"error":{"root_cause":[{"type":"security_exception","reason":"unable to authenticate user [elastic] for REST request [/_security/user/kibana_system/_password]","header":{"WWW-Authenticate":["Basic realm=\"security\" charset=\"UTF-8\"","ApiKey"]}}],"type":"security_exception","reason":"unable to authenticate user [elastic] for REST request [/_security/user/kibana_system/_password]","header":{"WWW-Authenticate":["Basic realm=\"security\" charset=\"UTF-8\"","ApiKey"]}},"status":401}

We don't have to ignore event.created here ?

No necessarily, because the event.created is copied from @timestamp, and it never changes, so the test won't fail if you don't ignore it.. event.ingested is dynamic.

Thanks for spotting it, Kevin. I might have forgotten to push this change.

Sweet, I got some audit logs this time too!
