Istio Support

[aleclerc-sonrai]

Hi there, I'm wondering if anyone has gotten a clickhouse installation from the clickhouse-operator working with Istio?

Currently I'm having trouble with the readiness/liveness probe upon startup, likely due to how the ports get bound to 127.0.0.1 instead of 0.0.0.0

Same, I've got the next cluster configuration after adding istio:

┌─cluster────────┬─shard_num─┬─replica_num─┬─host_name────────┬─host_address──────────────┬─port─┐
│ all-clusters   │         1 │           1 │ chi-test-0-0     │ ipv6:addr:was:here:19bc::d│ 9000 │
│ all-clusters   │         1 │           2 │ chi-test-0-1     │ ipv6:addr:was:here:19bc::7│ 9000 │
│ all-clusters   │         1 │           3 │ chi-test-0-2     │ 127.0.0.1                 │ 9000 │
...

It seems to me that cluster instances self-discovery doesn't go well within ipv6-only aws eks cluster running under istio.

And restarting operator pod helped somewhy - it couldn't resolve replicas services into a proper addresses, but after restart it has gone.
