This article mainly explains the "docker container installation and operation steps", the article explains the content is simple and clear, easy to learn and understand, now please follow the editor's ideas slowly in depth, together to study and learn "docker container installation and operation steps" bar!

Environment selection

The container needs management tools, runtime and operating system. Our choices are as follows:

Management tool-Docker Engine

Because Docker is the most popular and widely used.

Runtime-runc

Default runtime for Docker

Operating system-Ubuntu

Although there is a container OS such as CoreOS, considering that we are in our infancy, it is more appropriate to choose a familiar operating system. It is more advantageous to use container OS after you have a solid basic knowledge of containers.

Install Docker

In this section, we will install Docker in the ubuntu 16.04 virtual machine. Because the installation process requires access to internet, the virtual machine must be able to access the Internet.

Docker supports almost all Linux distributions, as well as Mac and Windows. The installation method of each operating system can be accessed at: https://docs.docker.com/engine/installation/

Docker is divided into open source free CE (Community Edition) version and paid EE (Enterprise Edition) version. Next we will follow the documentation to install the Docker CE version on Ubuntu 16.04 by following these steps.

Configure the apt source for Docker

1. Install the package that allows the apt command HTTPS to access the Docker source.

$sudo apt-get install\

Apt-transport-https\

Ca-certificates\

Curl\

Software-properties-common

two。 Add the official GPG of Docker

$curl-fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add-

3. Add the source of Docker to / etc/apt/sources.list

$sudo add-apt-repository\

"deb [arch=amd64] https://download.docker.com/linux/ubuntu\

$(lsb_release-cs)\

Stable "

Install Docker

$sudo apt-get update

$sudo apt-get install docker-ce

Run the first container

When the environment is ready, run the first container immediately and execute the command:

# docker run-d-p 80:80 httpd

The process can be described simply as follows:

Download the httpd image from Docker Hub. Apache HTTP Server has been installed in the image.

Start the httpd container and map port 80 of the container to port 80 of host.

Next, we can verify that the container is working properly through the browser. Enter http://[your ubuntu host IP in the browser]

You can access the container's http service, and the first container runs successfully! We have a WEB server with ease. With the deepening of learning, we will see that container technology brings us more value.

Image download acceleration

Because the Docker Hub server is abroad, downloading the image will be slow. Fortunately, DaoCloud provides us with free domestic mirroring service.

The following describes how to use mirroring.

Sign up for a user at daocloud.io for free.

After logging in, click the top menu "Accelerator".

Copy the Accelerator command and execute it in host (your command may be slightly different from mine).

Restart Docker deamon to experience the feeling of flying.

# systemctl restart docker.service
