kube-shell

Simple docker image to deploy as a Pod or Daemonset in Kubernetes for interactive sessions

To build and push docker image:

docker build -t jonmoter/kube-shell:latest .
docker push jonmoter/kube-shell:latest

What's in the image

To get an exhaustive list of everything in the image, read the Dockerfile. Here are some highlights of what's present:

• curl, of course
• httpie, a prettier version of curl
• grpcurl, like curl for gRPC
• httpstat, which displays HTTP connection timing info
• hey, an HTTP load generator
• TCP tools like tcpdump and tcptraceroute
• DNS tools like dig and host and dnstop
• jq for JSON wrangling

kubectl is not installed by default, because it's a pretty large binary. But there's an install_kubectl script that can be used to download it if you need it.

Truth Service

There's a minimal golang server that runs and listens on port 4242. You can use that if you want to run this docker imagine in a Kubernetes cluster and you want something you can send HTTP requests to. The binary is /usr/local/bin/truthserver

Deploying to Kubernetes

There's a DaemonSet definition in the kubernetes subdirectory. You can use that to run an instance of kube-shell on each node in your cluster. That can be handy if you want to try sending a request from a particular node or AZ.
