Generating Kubernetes YAML resources

Kubernetes has become the de facto standard for multi-node container orchestration. Kubernetes clusters allow multiple pods to be executed across nodes according to scheduling policies that reflect the node's load, labels, capabilities, or hardware resources (for example, GPUs).

We have already described the concept of a pod – a single execution group of one or more containers that share common namespaces (network, IPC, and, optionally, PID namespaces). In other words, we can think of pods as sandboxes for containers. Containers inside a Pod are executed and thus started, stopped, or paused simultaneously.

One of the most promising features that was introduced by Podman is the capability to generate Kubernetes resources in YAML format. Podman can intercept the configuration of running containers or pods and generate a Pod resource that is compliant with Kubernetes API specifications.

Along with pods, we can generate Service...
