zync resync domain issues

[duomotomo]

I had OpenShift 3.11 and 3scale 2.5 environment.
Recently i have upgraded to 3scale 2.6. Based on documentation at the end of migration process i have removed all routes and run zync domain resync with following command:

SYSTEM_SIDEKIQ_POD=$(oc get pods | grep sidekiq | awk '{print $1}')
echo ${SYSTEM_SIDEKIQ_POD}
oc exec -it ${SYSTEM_SIDEKIQ_POD} -- bash -c 'bundle exec rake zync:resync:domains'

After that I'v got many routes with "HostAlreadyClaimed" in my project:
oc get routes:
zync-3scale-api-2m5m4 HostAlreadyClaimed apicast-staging gateway edge/Redirect None
zync-3scale-api-2tjhb HostAlreadyClaimed apicast-staging gateway edge/Redirect None
zync-3scale-api-4dhsx HostAlreadyClaimed apicast-staging gateway edge/Redirect None

zync-3scale-api-kq2nf HostAlreadyClaimed apicast-production gateway edge/Redirect None
zync-3scale-api-lzh86 HostAlreadyClaimed apicast-staging gateway edge/Redirect None

And so on. Look like because we are using path routing in our environment and public host is the same for many apis domain sync tries to create them with the same hostname. It seem this is not neccessary and should be fixed.

Hello, is it possible to get update?

Hi duotomo - are you a Red Hat customer for 3scale?
If so, you should be able to get help resolving your issues via Support - by opening a Support case.

I'll ask people to take a look at this issue here, but will be "best effort"

thanks

We intentionally replicate each API as a Route (one to one), so it is more resilient to race conditions.
Zync tries to reliably reproduce state from Porta (API object) into OpenShift (Route object).
If it would start merging multiple API objects it could not reliably do its function. It opens door to race conditions and into decisions like what to do with multiple tenants etc.
Multiple Route objects don't hurt and once some API is deleted (and relevant Route) others will pick that host up and keep working.

Hello milkz,
why you need to merge anything, just don't create objects that not needed or just don't create them when path routing is enabled.
Don't hate me, but now i have tens of route objects in error state and you say this is doesn't hurt, but I think it's totally wrong. Is there a possibility do disable this sync "globally", not by service?
