Kubernetes Dashboard on Nutanix Karbon

Thanks. That had worked previously when I tried it. I initially thought there was a trick I was missing with RBAC since that is preferred in the later versions of K8S, but you are correct if you change the authentication method and remove RBAC from the equation.

Monitor Your Apps with Epoch

Hi dlink7, I have a support case for the VM issue and was able to figure out the tags as part of it (support was extremely helpful!). It looks like they aren't labels on the K8S, but rather tags that are set in the collector.yaml file when deploying the collectors (or post-install). It appears that these tags are set here versus created through the dashboard. Here is an example of what I was able to set for 2 tags in the collector.yaml file, redeploy the collectors, and then have it show up in the dashboard for usage: Collectors.yaml file: env: # DO NOT prepend http:// or https:// to the EPOCH_SERVICE_HOST value .... - name: EPOCH_TAGS value: "tag1,env:production,tag2,env:lab" Once redeployed they will show when looking at the container: kubectl describe po : Environment: EPOCH_TAGS: tag1,env:production,tag2,env:lab And finally, when looking at the metrics in the dashboard you can no filter by the tags: [img]https://d1qy7qyune0

Monitor Your Apps with Epoch

Thanks dlink7, I had read that section and went with the implementation of the tags post-install with the config file. I have created the tags.yaml file on both collectors and restarted, but I am not seeing the test tag I created in the interface. Part of what I might be missing is where these tags are supposed to show up and be applied in the dashboard? If I define a tag in the yaml file like this: --- # define instance tags here - tag - Owner:Keith Should I see this tag to apply and group VM's in the dashboard? If so, I am not seeing the tags or how to do that from my initial testing. Or does the usage of that tag require me to add something to the containers/POD definitions themselves to show up in the dashboard? It the how-to usage flow of tags that I am not seeing in the documentation and thus not sure what to expect that I was hoping to get some clarification on. Thanks! -Keith

Monitor Your Apps with Epoch

Hi, In some of these tutorials it shows a variety of tags to filter by when creating and filtering the Maps. I'm investigating and researching now, but I am missing the correlation of how to create these tags in the environment for EPOCH to pick up and filter on. I've noticed from the base install, that EPOCH reports some of the pods with "no_name" when they have a pod name associated. It has made me think there is some sort of label or annotation needed per container for EPOCH to pick up? Can you help explain or point me to an example of how someone would set the tagging for their containers for EPOCH to pick up and filter on? This is a bare-metal environment and not in AWS or another cloud that leverages a tagging system. Thanks! -Keith

Thanks Jose, That did work when I was testing. I thought maybe I was missing something on the user/passwd and I wanted to validate since getting into the dashboard has become locked down with the later versions and RBAC.....was hoping I was missing something to make life easier. Thanks for the quick response and update to the post! I'll continue on with my testing. Regards, -Keith

Kubernetes Dashboard on Nutanix Karbon

Hi, How did you enable a username/password for credentials to hit the secure URL for the dashboard. From my testing with the dashboard, it always prompts for a kubeconfig file or token given it only has the concepts of service accounts - I am not able to get it to work to prompt me for a user/password. I didn't deploy Heapster, just the dashboard for the moment. Jut curious if there is something I might be missing. thanks! -Keith

Windows Authentication Setup with CALM

Thanks [user=40533]Chandru[/user] This makes more sense now in the context of how you explain it. The one thing I am noticing as I go back to testing this is that the script I want to execute on the newly provisioned VM doesn't work as a shell script with the credentials I have stored in the blueprint. It only works as an EScript which is the opposite of what I think I saw last night (or it was too late for me to read clearly on my end :grinning: ). From the discussion above, it seems like the option for Shell with the credentials should be able to execute a remote command from the Karan server on the newly provisioned VM. But from what I am now seeing, this isn't working or I have something else up with either the credentials I have stored of how I am executing this. I have waited as much as 5 minutes for the sysprep to be done. Should this be working as a Shell script with the stored credentials? thanks! -Keith

Windows Authentication Setup with CALM

Thanks [user=40533]Chandru[/user] - I think it is making sense now. It looks like we are bypassing the login and simply putting the tasks (scripts) to be called after the VM has been provisioned. When I add a simple task to just output the version of powershell on the VM to a file location, the blueprint shows it as a success, but I don't actually see the file on the VM. Should this second task that has the script be an EScript or a Shell script with credentials? I was thinking an Escript from what I have read, but this is where some of the CREDSSP and Local mode stuff got a little confusing in the docs. I tried this as an Escript and it didn't work: $PSVersionTable.PSversion > "C:\Users\Administrator\psversion.txt" I just tried it as a shell script and gave it the credentials (domain account that the Karan service is running as) and that seems to work now when I check the VM that was spun up by CALM! You have been very helpful...thank you! I am going to try some more adva

Windows Authentication Setup with CALM

Hi Chandru, Thanks for the quick response. That works if I uncheck that - but that doesn't do the login check then right? By unchecking that I am just telling the blueprint not to perform the task correct? So I would expect I don't need the task that I created then if I am unchecking that. I did hear that there might be an issue with this timing, so I was hoping your sleep task would fake it out, but I am not sure yet why I can't get that to work. here is what I did that was a success. I left the task above in there and I have no package script bring called (that will be next in my testing to run commands). This worked well when I unchecked the login check. thanks for any insight. -Keith [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/b16c8761-0227-420d-bc02-ef83ba1b8e46.png[/img]

Windows Authentication Setup with CALM

Hi Chandru, Thanks for the info. Yes, I am able to execute commands remotely to the host that I build once it is up and online. I am not having much success with the sleep on the first run. I noticed your screenshot has the MSSQL service with tasks associated with the Create step, but I don't seem to have that when I create a new generic blueprint (attached). I am able to create a task, but it sits out there by itself. When I run the Launch, it seems the other steps in the "Action" tab are the ones that are executed. This seems like the one created automatically upon compilation, but was curious if this looks like the right location to set the sleep if you are just spinning up a generic VM? I'll try to play around some more, but not sure I am putting the sleep in the right place at the moment. thanks for any help!

How-To make an AHV VM into Prism Central Image

Thanks! That was what I ended up doing. There is a KB1533 on it that I eventually came across. Sounds like it might come back in the GUI at some point. -Keith
