Explain each components with Short Summary https://www.bestdevops.com/how-kubernetes-works-explain-each-components-with-short-summary-7/ Wed, 15 Sep 2021 10:15:45 +0000 https://www.bestdevops.com/?p=21445 Kubernetes cluster as two parts: the control plane and the compute machines, or nodes.Each node runs pods, which are made up of containers
The control plane is responsible for maintaining the desired state of the cluster, such as which applications are running and which container images they use. Compute machines actually run the applications and workloads.
Kubernetes runs on top of an operating system and interacts with pods of containers running on the nodes. desired state of a Kubernetes cluster defines which applications or other workloads should be running, along with which images they use, which resources should be made available to them, and other such configuration details.

]]> What is Kubernetes and its feature: https://www.bestdevops.com/what-is-kubernetes-and-its-feature-6/ Wed, 15 Sep 2021 10:07:45 +0000 https://www.bestdevops.com/?p=21422 Kubernetes is a container management system developed on the Google platform. Kubernetes helps to manage containerized applications in various types of physical, virtual, and cloud environments. Google Kubernetes is a highly flexible container tool to consistently deliver complex applications running on clusters of hundreds to thousands of individual servers.
Kubernetes helps you to control the resource allocation and traffic management
Features :
Automated Scheduling
Auto-healing capabilities
resource utilization
Horizontal Scaling & Load Balancing
Resource monitoring

The docker update command dynamically updates container configuration.You can use this command to prevent containers from consuming too many resources from their Docker host. With a single command, you can place limits on a single container or on many. To specify more than one container, provide space-separated list of container names or IDs

Command example:
docker update –cpus 4 320f02d6f0f7

Docker wait
Block until one or more containers stop, then print their exit codes

Example:
1st terminal
docker wait 320f02d6f0f7
In another terminal, stop the container
Docker stop 320f02d6f0f7
in the 1st terminal it exits returning 0

Docker is a platform and managing tool which has a containers

What is Container?
Container is a independent application used in Run time Env which contains 1 mount, 1 user, 1 Network and 1 PID Map

Benefits of Docker:
Its saves Cost, time and improves the Quality of Application.

Docker Architecture:
Docker uses a client-server architecture and docker client communicates with the Docker Server(Deamon) which can build docker containers. It is a Restful service where client and Server can communicate Remotely

Container lifecycle:
create -> start -> stop -> start -> restart -> pause -> unpause -> kill -> Delete

How Docker works:
Docker makes use of kernel namespaces to provide the isolated workspace called the container . When you run a container, Docker creates a set of namespaces for that container. … Each aspect of a container runs in a separate namespace and its access is limited to that namespace
