<p>Hello,</p>
<p>Thank you for your responses.</p>
<p>There is another question.</p>
<p>Our Pgpool runs in k8s pod. All services in k8s are connected to
the database through this Pgpool.</p>
<p>The addresses of the backend hostnames for master and replica
nodes in the Pgpool settings are specified as a dns name, for
example "master.patrcluster.services.consul".</p>
<p>DNS name resolution occurs in the DNS Consul. We also use Consul
as a discovery service and key/value storage.<br>
And Cosul DNS receives the following DNS requests every second: <br>
</p>
<p>------<br>

dbnode0 consul[860]: 2022-01-14T08:53:53.473Z [ERROR]
agent.dns: all resolvers failed for question from client:

[ERROR] agent.dns: all resolvers failed for question from

<p>------<br>
</p>
<p>Here the address 10.210.53.107 is the k8s address where Pgpool
works. Apparently, these requests are sent by Pgpool, but only
when it works in Kubernetes.</p>
<p>When we run Pgpool just in a separate docker image, this does not
happen.<br>
</p>
<p>Have you noticed such behavior of Pgpool? And how can we remove
these requests or leave as is? I would be grateful for any
comment or advice. <br>

Could you please tell us aboun pgpool deployment in kubernetes.
We are interested to know:
1. Are there the correct helms for deploying pgpool to kubernetes. If
so, where can we get them?

No. Pgpool-II community doesn't provide a Helm for deploying pgpool in k8s.
Below is the documentation to deploy pgpool in k8s.

<pre class="moz-quote-pre" wrap="">2. What strategy should be used to ensure high availability of the
pgpool service in k8s - the same as for other services in k8s, or should
there be any special HA configuration for pgpool in k8s?
</pre>
</blockquote>
<pre class="moz-quote-pre" wrap="">
You don't need special HA configurations for pgpool in k8s.
You can use the functionality of k8s to ensure high availability of pgpool,
just same as for other services in k8s
