simpledash

a simple, read-only, dashboard for your solutions running on k8s

try locally with skaffold

1. install skaffold
2. run skaffold run
3. in your browser navigate to localhost:1337
4. review the default settings in ./simpledash.yaml - e.g the namespaces being included in the setting SIMPLEDASH_NAMESPACES:

install in your k8s cluster

kubectl apply -f https://raw.githubusercontent.com/hellgrenj/simpledash/main/deploy/v0.3/simpledash-with-ingress.yaml

But you probably want to download the yaml above and tweak things like:

• tracked namespaces (deployment env var SIMPLEDASH_NAMESPACES, expecting json array)
• cluster name (deployment env var SIMPLEDASH_CLUSTERNAME, expecting string)
• Ingress host, tls
  and more...

so, what am I looking at?

Well, its not the dashboard for the DevOps team or the Ops people. It’s for the dev team that just want to know how their app or api is doing, what build is running in what environment, how to view the logs for one particular pod and “what the staging url was now again?”. And without having to login to a proper monitoring tool and sift through all the “irrelevant” information to get these fairly simple answers. At some point, somewhere, this tool scratched a real itch. =)

Simpledash will scan your cluster every 10 seconds (configurable) and push the cluster information over websockets to your browser. In the header you see "simpledash" and the name you set in the env variable SIMPLEDASH_CLUSTERNAME (see ./simpledash.yaml). In the top left corner you have a namespace filter option, this will dictate what is being presented below. You can also pass in an inital filter by using the ns query parameter, i.e localhost:1337?ns=simpledash

On the next row you can see any exposed ingress endpoints and deployments (per namespace) and the namespaces being monitored. Below this you can see the pods in your cluster and the nodes they live in. Each node has a timestamp in the upper-left corner so you can see how fresh the status/data is that you are looking at.

Each pod displays the:

• pod name
• namespace
• tag
• status
• view logs link (if enabled!)

..and if you hover over the pod you can see the image name

pods with status Running will have a green background.
pods with status Failed will have a red background.
Any other status = Yellow background.
Pods in the same namespace will have the same border color.
