Description

As discussed in #3922 (and #3337, #3252, #2598, #1780, ...) we need a new mechanism for storing activity entries.

[heiko-braun]

If we move to jaeger, there seem to be ongoing work around badger storage: jaegertracing/jaeger#760

[heiko-braun]

@chirino Do you still plan to work on this?

Current status
The following PRs have been merged to master:
#5280 Add jaeger-spring-boot-starter and enabled it in the syndesis server so it can participate in opentracing requests.
#5283 Add optional jaeger tracing for activity monitoring for the SB runtime.
#5285 Add a jaeger based ActivityTrackingService.

Still Pending:
Being able to optionally enable via syndesis CRD option the jaeger based activity tracing. I started a branch to do that at: https://github.com/chirino/syndesis/tree/jaeger-4
But it does not yet optionally install it.

[chirino]

It might be worth waiting until openshift template based installed don't need to be supported anymore so that we can have a more dynamic operator.

[chirino]

This is now completed:

1. Install syndesis as usual.
2. Install the Jaeger operator as described at: https://www.jaegertracing.io/docs/1.13/operator/#installing-the-operator-on-okd-openshift
3. As a cluster admin, grant the sydnesis operator access to create a jaeger instance:

NAMESPACE=`oc project -q`
oc create  rolebinding syndesis-jaeger-operator --clusterrole=jaeger-operator --serviceaccount $NAMESPACE:syndesis-operator

3. Update the sydnesis custom resource to enable the jaeger addon:
   oc patch syndesis app --type merge -p '{"spec":{"addons":{"jaeger":{"enabled":"true"}}}}'

[heiko-braun]

Do we fallback to the current activity logging when jaeger is not enabled?

[chirino]

No. If you enable the jaeger addon, the system will be configured for jaeger

[chirino]

We also need to do some work to also enable this feature to work when camel-k mode is enabled. Not sure if camel-k support is a must have or not.

[heiko-braun]

Yes, but what if jaeger is not enabled?

[chirino]

if you don't enable the jaeger addon, then syndesis continues to use db based activity logging.
