Summary

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.
