Title: DNS does not find docker containers in same network

Description:

I updated from envoyproxy/envoy-distroless:v1.31.5 to envoyproxy/envoy-distroless:v1.32.3 and now envoy does not resolve other docker containers in the same network anymore.

I enabled some logs and see the following:

[2025-01-15 10:48:49.504][28][debug][router] [source/common/router/router.cc:527] [Tags: "ConnectionId":"0","StreamId":"5305907000402733376"] cluster 'ext-authz' match for URL '/envoy.service.auth.v3.Authorization/Check'
[2025-01-15 10:48:49.505][28][debug][connection] [source/common/network/connection_impl.cc:1017] [Tags: "ConnectionId":"2"] connecting to <ip>:80

If I start envoy 1.31 the IP is the IP of my extauthz container in the docker network. Envoy 1.32 probably queries not the docker network resolver but my host resolver and gets a wrong IP. I would expect envoy to resolve the IP of the container.

Other clusters have the same problem, if I change to type: static everything works.
Names like auth.example.com get resolved correctly too.

Repro steps:

A simple gRPC request that matches /my.prefix/ and is forwarded to ext authz triggers this

Note: The Envoy_collect tool
gathers a tarball with debug logs, config and the following admin
endpoints: /stats, /clusters and /server_info. Please note if there are
privacy concerns, sanitize the data prior to sharing the tarball/pasting.

Admin and Stats Output:

Include the admin output for the following endpoints: /stats,
/clusters, /routes, /server_info. For more information, refer to the
admin endpoint documentation.

Note: If there are privacy concerns, sanitize the data prior to
sharing.

[agrawroh]

@trivialkettle Could you try explicitly passing in the resolver address using typed_dns_resolver_config?

[trivialkettle]

@agrawroh thanks for the answer. I played around with typed_dns_resolver_config but could not solve it.

At the end I solved it passing

dns_search: ""

to the envoy service in my compose.yaml. Though, strange that it happens only on v1.32. Maybe the order is now different?

[rogercoll]

I had the same issue when deploying the OpenTelemetry Demo. Setting dns_search: "" fixed the issue.
