Couldn't resolve server from bootstrap.servers as DNS resolution failed

[AlexVegaIT]

Hi,
I have a configuration which was working fine till today. Nothing has been changed, but I started receiving this error message today

"Couldn't resolve server *** from bootstrap.servers as DNS resolution failed for ***"

The same Kafka cluster host is working fine with other Kafka UI tool (Provectus).
The AKHQ instance I'm starting with docker-compose using yml configuration file.

How to resolve this issue and what is the root cause?

An update from this morning, I've resolved this issue within next steps

• Run the AKHQ container with "docker-compose -f file_name.yml up"
• Open another WSL window (if you are using Windows OS) and type "docker container list" to get a container ID
• In that same terminal/wsl then type "docker exec -u root -it CONTAINER_ID /bin/bash"
• Go to /etc folder and type "echo "nameserver 1.1.1.1" > resolv.conf"

Right after resolv.conf is amended AKHQ app will start resolving listed clusters, topics etc.
I hope that this will trigger you to investigate this and someone to help resolve this temporary.

Seems to be really related to your laptop configuration, no one I know have the issues since by default docker will use host dns.

Or easier way would be to add DNS list in a composer file

akhq:
image: tchiotludo/akhq
dns:
- 1.1.1.1
- 8.8.8.8
