Docker is a platform for virtualization that helps developers and software engineers to run their applications in a separate and isolated environment. With Docker, you can define the software infrastructure needed to run your application in a separate and standardized way and package it with your application into a portable and self-sufficient unit called a Container.

This technology provides features such as isolation, fast configuration, and easy mobility between development and production environments. By using Docker, you only need to define a Docker container for your application and its required runtime environment, package it into a portable bundle, and then run it on any Docker-compatible system.

The use of Docker not only reduces installation and configuration time but also allows you to run your applications on platforms that have different characteristics such as different operating systems, versions, and libraries.

The following mirrors can be used in nano /etc/docker/daemon.json to resolve internet problems:

{
  "registry-mirrors": ["https://docker.iranrepo.ir", "https://docker.arvancloud.ir", "https://docker.iranserver.com"]
}

Then, you can run the following commands:

systemctl daemon-reload
systemctl restart docker

• Creating a container from a specific image

docker container run my_image

• Creating a container from a special image and binding Docker port 8000 to 1000

docker run -i -t -p 1000:8000 --rm my_image /bin/bash

 :warning: You can use `/bin/bash` to have a better experience!

• Creating a container from a special image and binding Docker port 8000 to 1000 host and bind mounting the /HostPath folder of the host to /insidePath of the container

docker run -v /HostPath:/insidePath -p 1000:8000 my_image

• Creating a container from a specific image and executing the my_command command in Docker

docker container run -it my_image my_command

• Create a container from specific image and detach it (Run in the background)

docker run -d -p 1000:8000 --rm --name my_image my_image:latest

• Show list of my active containers

docker ps

• Show list of all my containers

docker ps -a

• Start a specific container

docker start CONTAINER_ID

• Stop a specific container

docker stop CONTAINER_ID

• Remove a specific container

docker rm CONTAINER_ID

• Display logs of a specific container

docker logs CONTAINER_ID

• Kill a specific container

docker kill CONTAINER_ID

• Create new snapshot from running container

docker commit CONTAINER_ID new_image_name

• Change timezone of container

 sudo rm -rf /etc/localtime
 ln -s /usr/share/zoneinfo/Asia/Tehran /etc/localtime

 # you can check it now :)
 date

• Show list of my docker images

docker images ls

• Get a simple Hello-world image

docker pull hello-world

• Run Hello-world docker image

docker run hello-world

• Build Docker image

docker image build . -t my_repo/my_image:my_tag

• Build Docker image from DockerFile

docker build -t my_repo/my_image:my_tag -f Dockerfile .

• Create a backup from docker image

docker save --output bk_khalooei.tar my_image:latest

• Load a docker image

docker load --input bk_khalooei.tar

• More information about Docker Image

docker inspect <imagename>

• Show list of my Docker volumes

docker volome ls

• Display the information of a volume

docker volume inspect VOLUME_NAME

• Delete all unused volumes

docker volume prune

• Docker version

docker version

• Enable Docker service on Linux

sudo systemctl enable docker
sudo systemctl start docker
