Docker Hosts
A Docker host is a piece of hardware that supports Docker containers and the operating system; in essence, this is the server. A machine that is located someplace in the hosting company’s data centre and operates round-the-clock to maintain your website or web application.
The Docker engine isolates its containers from one another and shares a portion of the host’s computational resources with them, much like a hypervisor. It does not execute unique guest operating systems for each of its containers, in contrast to a hypervisor. The Docker host kernel is shared by all containers. As a result, workloads in containers are unable to leverage capabilities that the Docker host kernel does not support.
Docker – Containers & Hosts
A common containerization tool in DevOps is Docker. It is an application deployment platform as a service for Docker containers. It consumes the least amount of resources, can be deployed more rapidly, and can scale easily while running your application inside of a container.
- Containers – Containers are “packages” of software that include an application’s source code, libraries, configurations, and dependencies. They make it easier for software to execute consistently and reliably across several machines.
- Docker Host – A real or virtual server that houses the Docker engine, Docker’s main component, is referred to as a “Docker host.” Workloads are contained and executed in Docker containers using the Docker engine.
