Lab 003: Docker Delete Container

Requirements​

One of the Nautilus project developers created a container on App Server 2. This container was created for testing only and now we need to delete it. Accomplish this task as per details given below:

Delete a container named kke-container, its running on App Server 2 in Stratos DC.

Note

This page preserves the original requirement text and documents one safe stop-and-remove workflow for the target container.

Prerequisites​

  • You can SSH to App Server 2 and switch to a privileged shell.
  • Docker is installed and the daemon is running on the host.
  • The container kke-container exists on the host before you start the removal steps.

Steps​

Login to the app server 2 and switch to root. For the server credentials, check out the Project Nautilus documentation.

sshpass -p  '********' ssh -o StrictHostKeyChecking=no steve@172.16.238.11
sudo su -
********

Check the running containers.

[root@stapp02 ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND               CREATED              STATUS              PORTS               NAMES
6cc8799c69a1        busybox             "tail -f /dev/null"   About a minute ago   Up About a minute                       kke-container

Stop the container then delete it. Verify afterwards.

[root@stapp02 ~]# docker stop kke-container
kke-container
[root@stapp02 ~]# docker rm kke-container
kke-container
[root@stapp02 ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

Verification​

  • Confirm the container no longer exists with docker ps -a | grep kke-container.
  • If the grep command returns no output, the removal is complete.
