5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Hello @jmoro, Karbon Cluster doesn’t require Calm or App management enabled. Could you open a support case? There’s probably something in the karbon-core logs that support can use to figure out why the container wasn’t started. Hi @vshuguet Thanks, for your suggestion. The last PC update (2020.8), solved the problem. I forgot to comment on the post about it.Thanks to all for your help.
Hello @Jubran We have a problem with Karbon. We can’t download images from the UI. We have activated browser developer options to see the calls to API.When we click the button “Donwload Centos” the browser shows this. The first one error is just loading the page. The second is when button is clicked. Reading your links we checked “docker ps” to see if the containers are running. Only UI was started. After restarting “karbon-core” and “karbon-ui” containers, the core container ends failing again.

Hi Jose. Problem solved!!. Loging into VM helped to understand the problem. The problem was a misconfiguration on the DHCP options. The scope had option 5 (Name Servers) defined instead the option 6 (DNS Servers) for the dns server list. For that reason the VM can't download from internet. Thanks for your help! Best Regards Javier.
Hi Jose. This is our environment (5 nodes) AOS 5.10.4.1 | Calm 2.6.0.6 | Epsilon 2.6.0.6 | Karbon 1.0.1 | NCC 3.7.1.2 | PC 5.10.5 | AHV 20170830.270 We have defined a new VLAN for karbon, one different than AOS, AHV and PC. Firewall access from Nutanix VLAN to karbon VLAN is all open. I see in the karbon cluster creation process that one VM is created, started and have an IP assigned from external DHCP (relayed). I'm able to connect on SSH in that machine. Example of networking definition for karbon VLAN: Network addresses on Karbon VLAN: 10.x.x.x/16 Service CIDR Ranges: 10.y.x.x/16 Pod CIDR Range: 10.z.x.x/16 Regards Javier

Have you solved Epsilon service down? Regards
