Red Hat OpenShift Development I: Introduction to Containers with Podman
Containerize a process by choosing a base image and by using the Containerfile instructions.
Create rootless containers by creating Containerfiles that do not run as a privileged user.
You can implement advanced container build and runtime patterns, which includes:
The use of the
ENVinstruction to create containers that can be deployed in different environments.The use of the
VOLUMEinstruction to store container data outside the container layered file system.The use of
ENTRYPOINT,CMD, and their interactions.Creating multistage Containerfiles to build smaller images that do not contain build-time dependencies.
