Containers

Containers are lightweight, portable units of software that package an application and its dependencies together, ensuring it runs consistently across different computing environments.

🧩 Key Concepts​

  • Isolation: Each container runs in its own isolated environment, sharing the host OS kernel.
  • Portability: Containers can run on any system that supports the container runtime (e.g., Docker), making deployment easy across development, testing, and production.
  • Efficiency: Containers are more resource-efficient than virtual machines because they share the host OS kernel.

🚀 Popular Container Technologies​

  • Docker: The most widely used container platform.
  • Podman: A daemonless container engine compatible with Docker.
  • Kubernetes: Orchestrates and manages containers at scale.
  • LXC/LXD: System containers for running entire Linux distributions.

📝 Notes​

  • Containers are ideal for microservices architectures.
  • Images are the blueprints for containers; they define what’s inside.
  • Containers can be managed individually or orchestrated in clusters.
