TIL that ‘kubectl port-forward’ can take a deployment. I had always picked a specific pod first.

Well, that looks handy! rakkess, a kubectl plugin to show an access matrix for all available resources. github.com/corneliusweig/… #Kubernetes
Woah! Trace me :) github.com/fntlnz/kubectl… Schedule bpftrace programs on your kubernetes cluster using the kubectl
A little weekend contrib, the `kubectl` tip of the day: wait like a boss … medium.com/@mhausenblas/k… @kubernetesio #kubectl #CLI
TIL `kubectl alpha diff -f <yaml file/dir>` Compares deployed resource with local yaml file. Where have you been all my life... ♥️ #Kubernetes
Ha! About time ;) > This project does not really introduce a kubectl plugin but a concept of how to provide a sudo like system for kubernetes access. github.com/postfinance/ku… #Kubernetes #CLI #kubectl

Not many more to go (assumes kubectl in pod)... $ kubectl --certificate-authority /var/run/secrets/kubernetes.io/serviceaccount/ca.crt --token $(cat /var/run/secrets/kubernetes.io/serviceaccount/token) --server https://kubernetes.default get pods
Excellent! And another one: $ export CURL_CA_BUNDLE=/var/run/secrets/kubernetes.io/serviceaccount/ca.crt $ APISERVERTOKEN=$(cat /var/run/secrets/kubernetes.io/serviceaccount/token) $ curl -H "Authorization: Bearer $APISERVERTOKEN" kubernetes.default … if you're allowed to ;)
Oh, and I suppose for completeness now we're here, from a pod inside the cluster... $ echo "${KUBERNETES_PORT}" tcp://10.42.42.42:443
neat, but couldn't you get the same info with a simple kubectl cluster-info? Prints the following for my local cluster: Kubernetes master is running at https://localhost:6443 KubeDNS is running at https://localhost:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
[TIP] if you’re new to a @kubernetesio cluster and unsure where the API server is, execute: $ kubectl get --raw=/api | \ jq .serverAddressByClientCIDRs[0].serverAddress -r 192.168.64.11:8443 This IP:port you see there, in my case Minikube, that’s the API Server ;)
