Ubuntu system uses Docker to build WordPress

Goal: Build WordPress in Docker

Installation Order:

• First of all to have a cloud server---to buy or build it yourself (i installed a virtual machine on the host, built a ubuntu14.04)
• Installing Docker
• Installing Docker Compose
• Install WordPress

What is Docker

• Dockers is open-source and is
• Docker is a container where you can install software to build the environment, much like a virtual machine, but faster and lighter
• The core of Docker is mirroring
• Docker Learning link Chinese: https://yeasy.gitbooks.io/docker_practice/
• Docker English Document: https://docs.docker.com/

Installing Docker

• Docker has a commercial version and community version of two, we use the community version of the Docker CE
• Several versions of Ubuntu are supported:
• 14.04 LTS
• 16.04 LTS
• 17.01 (Docker CE 17.11 Edge and higher only)
• Refer to Official document installation https://docs.docker.com/install/linux/docker-ce/ubuntu/#os-requirements
• The installation steps are as follows, very simple

Update the addresses of the sources listed in/etc/apt/source.list and/ETC/APT/SOURCES.LIST.D (update apt package index)

 ~# sudo apt-get update

Allow apt to use warehouses over HTTPS when installing packages

 ~# sudo apt-get install     apt-transport-https     ca-certificates     curl     software-properties-common

Add Docker official GPG key

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

Search for 8 digits after the fingerprint to confirm that the fingerprint is already 9dc8 5822 9fc7 DD38 854A e2d8 8d81 803C 0EBF CD88 key

~# sudo apt-key fingerprint 0EBFCD88输出：pub   4096R/0EBFCD88 2017-02-22      Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88uid                  Docker Release (CE deb) <[email protected]>sub   4096R/F273FCD8 2017-02-22

Set up Stble Warehouse, you can add word edege or test after stable word on command line, or two plus (different command line entered by operating system, see Official document)

~# sudo add-apt-repository    "deb [arch=amd64] https://download.docker.com/linux/ubuntu    $(lsb_release -cs)    stable"

Update APT Package index

~# sudo apt-get update

Install DOCKER-CE, the latest version is installed as follows

~# sudo apt-get install docker-ce

You can also make a version of Docker-ce, as follows

先查下都有哪些版本~# apt-cache madison docker-ce输出：docker-ce | 18.03.0~ce-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages

再指定版本安装，for example: sudo apt-get install docker-ce=18.03.0~ce-0~ubuntusudo apt-get install docker-ce=<VERSION>

Command line input docker run Hello-world check for successful installation

Installing Docker Compose

Official Installation Documentation: https://docs.docker.com/compose/install/#install-compose

Here is the PIP installation, first install PIP, such as the following command

~# apt-get install python-pip

PIP has been installed, directly below this command ( How to determine the PIP installation: directly enter the following command, if not installed will prompt )

~# pip install docker-compose

Check that the installation was successful, enter the following command

~# docker-compose -version

Install WordPress

Official website Installation document: https://docs.docker.com/compose/wordpress/#build-the-project
Create a project name, such as mywordpress (which directory can be created)

~# mkdir mywordpress

Enter the project file

~# cd my_wordpress

Create a Dcoker-compose.yml file

~# vim docker-compose.yml

The file contents are as follows
