Docker Networks

Everything to docker networks and more. You'll find it all here.

Definition

Docker Networks what are they? Very-Simple, imagine them as a bridge between containers and the external environment. It allows traffic to travel between the containers (internal environment) to external systems (external environment). This is done by offering various networking models and configurations, Docker Networks empower developers to design flexible, scalable and secure network architecture for their containerized applications. It helps with restricting access to some container services.

Use Cases

Docker Networks offer versatile solutions for containerized environments, allowing seamless communication and connectivity. Let's delve into some prominent use cases where Docker Networks play a crucial role:

  1. Microservices Architecture: Docker Networks enable communication between microservices in containerized applications, supporting scalability and fault isolation.

  2. Multi-Tier Applications: Docker Networks facilitate the deployment of multi-tier applications by connecting frontend, backend, and database containers, ensuring secure and efficient communication.

  3. Hybrid Cloud Deployments: Docker Networks allow for seamless communication between containers across on-premises and cloud environments, enabling organizations to leverage both infrastructures effectively.

Docker Networks provide indispensable capabilities for a variety of use cases, including microservices architecture, multi-tier applications, and hybrid cloud deployments. By enabling efficient communication and connectivity between containers.

Docker Network Types

If you ever created a docker network over Portainer you may have noticed that there are multiple network types you could use to configure your own customized docker network. Then you also may have realized that they aren't really types but more akin to divers for the docker network. There a five different drivers, these drivers are the following:

  1. bridge:
  2. host:
  3. overlay:
  4. ipvlan:
  5. macvlan:
