cdemers / kshell.sh
Created August 7, 2019 00:02
Shell script to be used to simplify opening a shell in a container within a pod in a Kubernetes cluster.
#!/bin/sh
# Using this script you simply have to specify the first letters of a pod
# to open a shell, the default shell is bash, but you can specify an
# alternative as second parameter.
#
# For example, if you have the two following pods:
# - caching-service-blablabla-123123-abcdef
# - creditcard-frontend-blabla-3213213-fghijk
