Add a MariaDB container which the process will bind on port 3306. 2. Add an Apache container which the process will bind on port 80 & 443. - The pod uses a single network namespace, - The pod exposes ports from the namespace. - The containers are processes within a single pod. - A single process in the namespace binds to each port.Getting Started Guide. 1. Introducing CRC. 1.1. About CRC. CRC brings a minimal OpenShift Container Platform 4 cluster and Podman container runtime to your local computer. These runtimes provide minimal environments for development and testing purposes.

MicroShift is a research project that is exploring how OpenShift OKD Kubernetes distribution can be optimized for small form factor devices and edge computing. Containers themselves are light, but by default a container has access to all the memory resources of the Docker host.

That includes containers in registries such as docker.io and quay.io. In this article, I'll show you how to use podman to build a container image and create a container from it.
