Yeah, definitely not getting that. I guess I need to look into it some more...

Interesting. There is a dashboard...

Running "kubectl proxy" starts and gives access to the dashboard. However, going to the dashboard is just a JSON list of stuff. Is there something that I missed?

Marko Luksa wrote:You can try running kubectl describe pods   (or kubectl describe pod umstore). You'll see a list of events at the bottom, which should tell you why the container isn't starting.

Thanks. Visibility is a great thing....

Looks like the error is ... "hostPath type check failed: C:\umstuff is not a directory". The directory is definitely there. Additionally, since I thought it may be a Linux / Windows difference, I also tried "C:/umstuff" and "C:\\umstuff". They all failed. Could this be a permissions thingy?

Thanks,
Henry

First, not sure if this is the best place for this, so may move this topic around later...

To start, I got Docker and Kubernetes working fine on my Windows 10 laptop. I am able to start and attach onto the image fine. Next step, I changed the YAML file so that it will mount a directory on my laptop (using the host path option). This doesn't work -- and leaves the image stuck on startup...

C:\> kubectl get pods
NAME                       READY     STATUS                  RESTARTS   AGE
umstore                    0/1         ContainerCreating   0                1h

So, I guess the questions are... Specifically related to my issues, what should I look at? And in general, related to all issues, how do I get better visibility on what is going on? Of course, I can't fix something, if I don't know why the image isn't starting.

Thanks for any hints,
Henry

What's that(...brand new Celebrity Edge)?

It's a Cruise Ship from Celebrity Cruise Lines, that just got released...

Henry

From some reason, with a title like "Edge is out" and in the "Meaningless Drivel" forum, my first thought was that this would be a topic about the brand new Celebrity Edge...

Kinda disappointed now...

Privilege of granting cows starts from Rancher title.

Agreed. Girbot promotions do not grant extra privileges at the moment. Regardless, have a couple of cows for your inconvenience.

Bumping this topic with some news !! ...

Niantic / Pokemon Company just announced the addition of PvP -- ie. Player vs. Player battles -- for Pokemon Go. This is significant for two reasons. One. It may be the foundation for multiple battle types, likely leading to tournaments, in the future. And two. This completes the feature set mentioned in the trailer for Pokemon Go, released 2 1/2 years ago, when it was first announced in 2016!

This news is all hype at the moment. Will know more in a month...

It should be easy to go from the description to a diagram that puts the description in graph form. Did you work out the rest? If not, tell us what you did so far. If so, show us what you draw out so far. And of course why.

The img tag requires an URL to an image file. In your case, it is to a html file.
