VMs or Containers
VMs are great for running multiple, isolated OS environments on a single hardware platform. They offer strong security isolation and are useful when applications need different OS versions or configurations.
Containers are lightweight and share the host OS kernel, making them faster to start and less resource-intensive. They’re perfect for microservices, CI/CD pipelines, and scalable applications.
Smart engineers focus on the right tool for the job rather than getting caught up in “better or worse” debates.
Use them in combination to make life better.
Popular container technologies
Docker: The most widely used container platform, known for its simplicity, portability, and extensive ecosystem.
Podman: A daemonless container engine that’s compatible with Docker but emphasizes security, running containers as non-root users.
Images
The image is the prototype or skeleton to create a container, like a recipe to make your favorite food.
Container
A container is the environment, up and running and ready for your application.
If Image = Recipe, then Container = Cooked food.
Where to get the Image from?
Docker Hub
For both Podman and Docker, images are from the Docker Hub.
NOTE: INSTALL DOCKER OR PODMAN (Not BOTH)
Podman on Windows
https://podman-desktop.io/docs/installation/windows-install
Once installed, verify the installation by checking the version:
podman info
Podman on MAC
After installing, you need to create and start your first Podman machine:
podman machine init
podman machine start
You can then verify the installation information using:
podman info
Podman on Linux
You can then verify the installation information using:
podman info
