Containers differ from VMs by providing only the necessary runtime dependencies, such as the required application-specific libraries for a program to run, rather than a full operating system.
Use container images to create container instances. Container instances are executable versions of the image, and include references to networking, disks, and other runtime necessities.
Podman is a container engine to build and run containers on an individual host.
Kubernetes and Red Hat OpenShift Container Platform (RHOCP) orchestrate containers across multiple hosts called nodes.
RHOCP is a set of modular components and services that are built on top of Kubernetes to add capabilities for the following features:
- Remote management
- Multiple tenants
- Increased security
- Continuous integration
- Continuous development
