Environment

• Self Managed Cloud Platform9- v5.9.0 and v5.9.1.

Cause

While troubleshooting it is identified that the nginx service inside nginx pod is not started as it tries to resolve s3-us-west-1.amazonaws.com in air-gapped environment.

Answer

This issue has been fixed in the SMCP-5.9.2 release onwards.

Workaround

1. If the onprem setup does not have a private DNS, empty the /etc/resolve.conf file and add nameserver {NODE_IP} in the file.
2. Otherwise, if there is a custom DNS setup, add the entries of the custom NS in the /etc/resolve.conf file.
3. Run /opt/pf9/airctl/airctl advanced-ddu create-mgmt --config airctl config as mentioned in the documentation published to get the management cluster up and running.
4. After the mgmt-cluster is up and running, append the s3 url entry in the nodelet-bootstrap-config.yaml i.e, add the entry 34.35.69.42 s3-us-west-1.amazonaws.com http://s3-us-west-1.amazonaws.com to the file nodelet-mgmt-cluster.yaml. The DNS field should look like the one mentioned in the below snippet.

dns:

corednsHosts:

- 34.35.69.42 s3-us-west-1.amazonaws.com

5. Run /opt/pf9/airctl/airctl start --config airctl config for the DU to start.
