About this Hands-on Lab

Every journey has to start somewhere. In this lab, we jump right into the deep end and look at how to launch and interact with our first container! Once complete, you’ll know how to start, interact, and stop a container.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Run Your First Podman Container

Let’s try the following:

  1. Check for running containers as cloud_user and root
  2. Check for local container images
  3. Search for httpd-24 container images
  4. Run the docker.io/centos/httpd-24-centos8 image
    • In detached mode, with a tty to run commands
  5. Check for running containers as cloud_user again
  6. Check for local container images again
  7. Check the contents of the /etc/redhat-release file on the server
  8. Open a bash shell in our container
    • Check the contents of the /etc/redhat-release file in the container
    • Try accessing the Apache web server running on port 8080 using curl
    • Exit the container’s bash shell
  9. Try accessing the Apache web server running on port 8080 using curl from the server
    • This will fail as we haven’t published port 8080 on the container
Clean Up

Let’s clean up after ourselves!

Do the following:

  1. Check for running containers as cloud_user again
  2. Stop our running container
  3. Check for running containers as cloud_user again and verify it’s stopped
  4. Remove the container
  5. Check for running containers as cloud_user again and verify it’s removed
  6. Check for local container images again
  7. Remove our httpd-24-centos8:latest image from local storage
  8. Check for local container images again
