Bitbucket DNS name resolution failure

Sheshansh Tripathi

While I am running the bitbucket pipeline, randomly pipelines get failed with the error of bitbucket DNS name resolution failure, this is very random and frequent. Please provide a permanent fix for it. Runners are hosted on premises. Below are the screenshots for the errors:

Hello @Sheshansh Tripathi and welcome to the Community!

As you are using self-hosted runners, could you please confirm if the runner's host is behind a firewall? If yes, it's important to make sure that the IP addresses listed in the following documentation are allowed in the firewall, so the runners can connect to Bitbucket's infrastructure : 

• Valid IP addresses for bitbucket.org, api.bitbucket.org, and altssh.bitbucket.org 

If after allowing the IP addresses you are still facing the issue, you can also try forcing the DNS resolution through a different nameserver, such as Google DNS (8.8.8.8) by adding the following command in your pipeline step's script : 

echo "nameserver 8.8.8.8" > /etc/resolv.conf

This should be added before the command that is failing with DNS resolution.

Hope that helps! Should you have any questions, feel free to ask!

Thank you, @Sheshansh Tripathi !
