You can use oc debug to open a shell to debug one of many OpenShift components.
$ oc debug node/ip-10-0-141-105.ec2.internal
Starting pod/ip-10-0-141-105ec2internal-debug ...
To use host binaries, run `chroot /host`
sh-4.2# cat /host/proc/cmdline
BOOT_IMAGE=/ostree/rhcos-... console=tty0 console=ttyS0,115200n8
rootflags=defaults,prjquota rw root=UUID=fd0... ostree=/ostree/boot.0/rhcos/16...
coreos.oem.id=qemu coreos.oem.id=ec2 ignition.platform.id=ec2 selinux=0
sh-4.2# exit
Using oc exec allows the remote execution of commands within the specified container within a pod.
$ oc exec mypod date
