Podman

Podman is an alternative to Docker for running containers on Linux. It is similar to Docker in many respects, but differs in some key areas:

• Doesn't require root privileges by default

Container orchestrators

A container orchestrator performs orchestration, i.e. the management of containers across nodes (which may be across different machines). For example, if you have two web nodes (with a load balancer) and a database node, your orchestrator will ensure that all the nodes are configured and can talk to each other as needed.

Orchestrators include:

• Kubernetes
• Apache Mesos
• Docker Swarm

Orchestrators are generally not compatible with each other(?)
