Docker installation and easy to use introductory tutorial

The installation

Due to the linux system I use, which supports docker natively, it is relatively easy to install

1: Install using the following official script:

wget -qO- https://get.docker.com/ | sh

2: Input the following command to verify whether you can view the version number, it can be installed successfully

sudo docker version

3. It is suggested to add the current users to the Docker user group, so that sudo can be avoided

sudo usermod -aG docker your_username

4: sudo permission will not be effective until login again

logout

At this point, your docker environment is quickly installed

Simple to use

Cut from hello world as follows

docker run hello-world

You'll see something like this

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
 executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
 to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
