How Docker works?
Docker simplifies the process of deploying, managing, and scaling applications by using containerization. Containers ensure consistency across different environments, as they encapsulate everything needed to run an application.

Lifecycle of Containers?
Create container

Run docker container

Pause container

Unpause container

Start container

Stop container

Restart container

Kill container

Destroy container

Top 10 Docker Commands?

docker create
docker ps
docker start
docker stop
docker restart
docker pause
docker unpause
docker kill
docker rm
docker exec

Docker’s higher level of architecture revolves around a client-server model, where the client interacts with the Docker daemon (server) to manage containers and related resources. At its core, Docker consists of three key components: the client, the daemon, and images. Client and daemon communicate using a REST API, over UNIX sockets or a network interface

Lifecycle of Containers?

Docker container lifecycle consists of five states: creation, running, paused, stopped, and killed or deleted

Top 10 Docker Commands?

1- Docker Run
2- Docker Pull
3- Docker PS
4- Docker Stop and Docker Start
5- Docker Logs
6- Docker Exec
7- Docker Build
8- Docker Images
9- Docker RMI
10- Docker Network

How Docker works?
To run the docker first you need an image, then you can create a container. In a container you can run application.

Lifecycle of Containers?
Create, start, run, pause, unpause, stop, restart, kill, destroy

Docker is an open-source platform designed to automate the deployment, scaling, and management of applications using containerization. Containers are lightweight, portable, and self-sufficient units that include everything needed to run a piece of software, including the code, runtime, system tools, libraries, and settings.

How Docker works?
Docker able to operate through a client-server architecture and leverage containerization to encapsulate applications and their dependencies in isolated environments.

Lifecycle of Containers?
It involves several stages from its creation to its removal.

Create container
$ docker create –name ubuntu-cont ubuntu
Run docker container
$ docker run -itd ubuntu
$ docker run -itd –name ubuntu-cont ubuntu
Pause container
$ docker pause <container-id/name>
Unpause container
$ docker unpause <container-id/name>
Start container
$ docker start <container-id/name>
Stop container
$ docker stop <container-id/name>
Restart container
$ docker restart <container-id/name>
Kill container
$ docker kill <container-id/name>
Destroy container
$ docker rm <container-id/name>

Top 10 Docker Commands?
docker run
docker ps
docker build
docker images
docker pull
docker stop
docker start
docker rm
docker rmi
docker exec

Docker use os-level virutalization to run platform as a service applications in very simple and fast way.

How Docker works?

Docker manage containers – every container can be a different application. Container can be started/stopped/restarted/paused… in similar bur simplest way as virtual machine.

Lifecycle of Containers?

created – running – stopped – paused – killer

Top 10 Docker Commands?

• docker create
• docker ps
• docker start
• docker stop
• docker restart
• docker rm
• clear
• docker images
• docker pause
• docker unpause

How Docker Works:

Docker uses a client-server architecture.
The Docker client talks to the Docker daemon,
Docker images are read-only templates used to create containers.
Containers are runnable instances of images.
Docker registries store Docker images. Docker Hub is a public registry that anyone can use.

Lifecycle of Containers:

Create,Run, Pause/Unpause, Stop, Restart,Kill, Remove

Top 10 Docker Commands:
docker run
docker ps
docker images
docker pull
docker build
docker stop
docker rm
docker rmi
docker exec
docker logs

2. it make use of a dockerfile which contains the set of instructions for building a Docker Image. 
A Docker Image serves as a template for creating Docker containers. It contains all the necessary code, runtime, system tools, libraries, and settings required to run a software application.

3. create -> start -> stop -> start -> restart -> pause -> unpause – > kill – > remove

4. docker create, 
docker run,
docker pause
docker unpause
docker start
docker stop
docker restart
docker kill
docker rm 
docker ps

2) How Docker works?
Docker uses resource isolation in the OS kernel to run multiple containers on the same OS. It downloads and run container images from registries.

3) Lifecycle of Containers?
Created, Running, Paused, Stopped, Deleted

4) Top 10 Docker Commands?
docker ps
docker images
docker pull
docker create
docker run
docker start
docker pause
docker unpause
docker kill
docker restart
docker rm
