docker ps -al

docker commit <CONTAINER ID> <IMAGE ID>

docker rm -f <CONTAINER ID>

docker rmi -f <IMAGE ID>

docker build -t <REPOSITORY NAME>/<IMAGE NAME>:<TAG NAME> <DOCKERFILE PATH>

docker run -it -p <HOST PORT>:<CONTAINER PORT> -v <HOST DIR>:<CONTAINER DIR> -e <KEU>=<VALUE> <CONTAINER ID>

docker exec -it <CONTAINER ID> /bin/bash

⁠Mount Host Directory from OS X:

vboxmanage showvminfo dev

From host: vboxmanage sharedfolder add <MACHINE NAME> --name <NAME OF SHARED DIR> --hostpath <PATH TO SHARED DIR> --transient

docker-machine ssh <MACHINE NAME>

In Docker machine VM:

mkdir <PATH TO SHARED DIR>

sudo mount -t vboxsf -o uid=$(id -u docker),gid=$(id -g docker) <NAME OF SHARED DIR> <PATH TO SHARED DIR>

sudo umount <PATH TO SHARED DIR>

⁠kubectl Commands

kubectl create -f <filename>

kubectl logs couchbase-node-0

kubectl run -i --tty --image busybox dns-test --restart=Never --rm /bin/sh

kubectl delete <kind> <name> --grace-period=0 --force

kubectl cluster-info

kubectl cp <namespace>/<pod>:<file> <local file>

kubectl get po --field-selector=status.phase==Running -l app=k8s-watcher

⁠Access Clusters Using the Kubernetes API

APISERVER=$(kubectl config view | grep server | cut -f 2- -d ":" | tr -d " ")
TOKEN=$(kubectl describe secret $(kubectl get secrets | grep default | cut -f1 -d ' ') | grep -E '^token' | cut -f2 -d':' | tr -d '\t' | tr -d '[:space:]')
curl $APISERVER/api/v1/namespaces/default/pods --header "Authorization: Bearer $TOKEN" --insecure
