In this chapter, you learned:
Containers provide a lightweight way to distribute and run an application and its dependencies that may conflict with software installed on the host.
Containers run from container images that you can download from a container registry or create yourself.
Podman, provided by Red Hat Enterprise Linux, directly runs and manages containers and container images on a single host.
Containers can be run as root, or as non-privileged rootless containers for increased security.
You can map network ports on the container host to pass traffic to services running in its containers. You can also use environment variables to configure the software in containers.
Container storage is temporary, but you can attach persistent storage to a container using the contents of a directory on the container host, for example.
You can configure Systemd to automatically run containers when the system starts up.
Click CREATE to build all of the virtual machines needed for the classroom lab environment. This may take several minutes to complete. Once created the environment can then be stopped and restarted to pause your experience.
If you DELETE your lab, you will remove all of the virtual machines in your classroom and lose all of your progress.
