Ubuntu Docker Installation

1.ubuntu16.04 Environment

installation command:

sudo apt-get update
sudo apt-get install Docker.io

2. Start the Docker backend service

runoob@runoob:~$ sudo service docker start

3. Mirroring Acceleration

In view of the domestic network problems, the subsequent pull Docker image is very slow, we can need to configure the accelerator to solve, I am using NetEase's Mirror address: http://hub-mirror.c.163.com.

The new Docker uses/etc/docker/daemon.json (Linux) or%programdata%\docker\config\daemon.json (Windows) to configure Daemon.

Please include in the configuration file (if you do not have the file, please build one first):

{
  "registry-mirrors": ["http://hub-mirror.c.163.com"]
}

Docker Hello World

Docker allows you to run an application within a container, using the Docker Run command to run an application within the container.

Output Hello World

runoob@runoob:~$ Docker run Ubuntu:15.10/bin/echo "Hello World"
Hello World

Resolution of each parameter:

Docker:docker binary execution file.

Run: Runs a container with the previous Docker combination.

UBUNTU:15.10 Specifies the image to run, Docker first looks for the presence of the mirror from the local host, and if it does not, Docker downloads the public image from the mirrored warehouse Docker Hub.

/bin/echo "Hello World": Commands executed in the boot container

The full meaning of the above command can be interpreted as: Docker creates a new container with ubuntu15.10 image, then executes Bin/echo "Hello world" in the container and outputs the result.
