Desktop Application for Kubernetes

skippbox is a Desktop application to manage applications deployed on Kubernetes. It supports multiple k8s endpoints and accesses a public application store.

This is still a work in progress, expect frequent changes

By default it will connect with a k8s API server running at http://localhost:8080/api

Snapshot

Here is a preview of what it looks like

Skippbox snapshot

Requirements

You will need a Kubernetes endpoint configured in your kubectl configuration file.

If you are not familiar with Kubernetes yet, you can use boot2k8s to get a one node Kubernetes cluster running locally. Go to the boot2k8s page and set it up.

Run in development

`skippbox`` is a NW.js application similar to Docker Kitematic but aimed at Kubernetes operations.

Clone the repository and install the application:

$ git clone https://github.com/skippbox/skippbox.git
$ cd skippbox

Install nwjs

$ npm install nw

$ npm install

Then start the UI with:

$ npm start

Support

If you experience problems with skippbox or want to suggest improvements please file an issue.

ansible-cloudstack's Issues

DNS service not working

Hello,

For some reason I can't make any dns resolution like:

kubectl exec busybox -- nslookup kubers.default.svc.cluster.local localhost
kubectl exec busybox -- nslookup kubernetes.default
kubectl exec busybox -- nslookup google.com

kubectl get pod --namespace=kube-system
NAME                                READY     STATUS             RESTARTS   AGE
kube-dns-v11-yx02q                  3/4       CrashLoopBackOff   13         45m
kubernetes-dashboard-v1.1.0-1lrhz   1/1       Running            0          45m

I tried to redeploy all on new hosts with kube_version=1.4.6 and 1.5.0-beta.2 but sames issues.

I saw many people have the same issue. I tried to delete the secret and restart my nodes, no success.
kubernetes/kubernetes#24812
kubernetes/kubernetes#23111

In logs:

If you know any quick resolution, I am open to it ;-)

Thank you!
