Kubecmd is a simple tool that allows you to send commands (or arbitrary strings)
to the input stream of the entry point process of a running kubernetes pod. This is
useful as kubectl attach doesn't work well with scripts.
To send say "Hello World!" to a pod named some-pod that is running in the dafult
namespace, simply run the following command:
$ java -jar kubecmd.jar some-pod "say \"Hello World!\""
To reference a different namespace, use -n or --namespace:
$ java -jar kubecmd.jar -n some-namespace some-pod "say \"Hello World!\""
If you do not want to send a carriage return/new line at the end of the command, use
-c or --no-carriage:
$ java -jar kubecmd.jar some-pod "say \"Someone needs to press enter :–(\"" --no-carriage
To build kubecmd, just run the :jar Gradle Tak:
$ ./gradlew build :jar
