Did I do anything wrong or missing config on this bundle ?. I tried to deploy more than 10 times and have the same error. Please help me on this issue

Thanks,

Hello Trinh,

What does the output of juju status look like?

Have you unsealed Vault and provided it with means to provide certificates to the deployment?

3

This is the output of juju status : Ubuntu Pastebin
Yes, I already unseal VAULT, create CA, and reissue certificate.

Thank you for responding Trinh, that deployment looks great!

The OVS bridges being marked as DOWN in the ip link output is normal.

If you configure networks in OpenStack including an external network and attach a router you should be able to ping the router external IP.

You can find the IP either by querying OpenStack or by looking at the output of ovn-nbctl show from the unit that is leader for the Northbound DB. Please refer to the usage section of the Open Virtual Network appendix in the OpenStack Charms Deployment Guide.

Thanks, yes that is my real problem. I can create router, external network, router interfaces, set gateway for external network, assign floating ip. But I can’t ping floating ip or ssh from external network . I can ping router’s ip good. So with my limited knowledge. I guessed it caused by OVS bridges. But if it’s normal . I will check on other things.

This is some output on ovn. If you have time, please give me some advice to troubleshoot

This is ovn-sbctl show, the instance created on S0042 host

If you can ping the external router ip that means that the external networking and bridge configuration should be ok.

So on to instance connectivity, what does the security group rules look like for the security group attached to the instances? Does it allow ICMP and SSH to the instances from the network you are attempting to connect from?

If you look at the instance console, openstack console log show <INSTANCE ID or NAME>, does it appear to have successfully retrieved metadata?

Thank you so much for helping me
Based on your comment, I can sort out it. My issue caused by a config vlan id on network interface port on MAAS. So when the packet go out it had a vlan tag. Now, I can connect to the instance.

Thanks again for helping me alot.
