Welcome to your first challenge in *The Quest for More Yummies*. In this hands-on lab, we are tasked with preparing our environment for maximum snack acquisition for the people of SpaceBones by installing Docker and then acquiring images from DockerHub.
Successfully complete this lab by achieving the following learning objectives:
- Install Docker from the Default CentOS 7 Repository
After logging into the server, install the latest version of
sudo yum -y install docker
- Set User Permissions
Drop down to
root. Create a new group named
docker, and then add the
cloud_useruser to the group.
- Enable and Start Docker Service
Once installation completes, enable and start the service using
Log out of
cloud_user, and then log back in:
ssh cloud_user@<PUBLIC IP>
- Run the `hello-world` Container Image
After starting and enabling Docker, run the
hello-worldcontainer image to verify installation.
- Pull Images
After getting a valid return message from the
hello-worldimage, pull the following images into your
Dockerrepository to prepare for the next exercise.
