Docker can help you realize your dream. And I can help you realize that dream. What is Doug? Setting up a test environment for software experiments can be difficult. This is especially true in WordPress. You must set up the web server, database, credentials, and all of their contents. The web server then continues to open, consuming memory. Because many times we are so lazy that we only run when we need it. Wouldn’t it be better to open WordPress only when we want to work and perform simple installation and all other tasks? The
Input docking station. James governor of red bank, an industry analyst blog, introduced the idea behind docker: Docker makes it easy to container everything you need to run an application, including the code itself, the runtime, and system tools. In theory, it can be developed on a laptop and then deployed to all servers. Unlike virtual machines, containers contain applications and all dependencies, but share the kernel with other containers. This is an efficient model that explicitly maps to current development thinking, such as continuous integration and microservices. The
Note: if you have any questions, docker is written in an easy to learn python programming language. If necessary, you can view the code on GitHub. Installing docker on windows was originally a Linux program, but it was successful among system administrators. Microsoft raised funds for porting docker to windows. Docker was launched in the summer of 2016. However, the first iteration of docker for windows was strictly designed for the data center. To perform this operation, windows 10 Pro is required, which includes hardware supported virtualization and Hyper-V virtualization clients. Before the release of windows docker, you need to set up some third-party tools to perform slightly complex installation. The
First, you need VirtualBox, an open source virtual machine administrator owned by Oracle, but it can be ed for free. The latest version is 5.1.10. The first time you open VirtualBox, you will be prompted to install the expansion pack. Perform this task; In particular, if you want to open word press in the browser of the actual computer. It will be explained in detail later. docker toolbox. Most importantly, the application (free) creates a small version of Linux and runs docker on the virtual machine. Technically, if there is no VirtualBox, the current version of docker toolbox will install VirtualBox by itself. This includes the following applications: The
Git is a distributed source control system. It is provided together with docker machine docker compose (described in detail later), a GUI container management tool named kitematic (alpha software that doesn’t work very well at present), its own command line environment and text editor atom. Run toolbox to create a virtual machine on the VirtualBox. The virtual machine uses the docker command and some default shell tools to use the command line for the Linux version
Create. Nothing is cooler than a graphical interface. All of these files are located in the \/usr\/local\/bin directory of the Linux VM. The
After the QuickStart process is complete, an interactive shell appears. To ensure that all programs are running properly, use docker run Hello world. After that, you can use docker to set word press. Installing docker on Linux docker was originally built for Linux, so it is much easier to run it directly on Linux. Reasonably, the latest release (Ubuntu, Fedora, openSUSE, Debian and all descendants) is likely to include docker engine, docker machine application and docker compose functions, which simplifies image creation in a good way. Configuration file. The advantage is that the Linux distribution also has a graphical browser to test. This is how to install word press. The
Use the package manager to install docker, docker bash complex, and docker compose. It’s true, that’s it! Install docker on Mac OS X docker for OS X runs on Yosemite (MAC 10.10). Therefore, compared with Windows users, it is more likely to install and run new products on Mac. Please read the instructions carefully before installing the application. Mac docker runs in hyperkit VM system, including docker engine, command line interface, docker compose and docker machine. The
Use the command line to set word press, and then set word press in docker VM. There are several ways. The first one was proposed by blogger James Wade. The good news is that from now on, the operating system running on your computer is no longer important. If you live in a docker environment, they all work the same way. Enter the MKDIR wptest command to create a new directory for the WordPress environment. Change the directory to the directory CD wptest you just created. Now the fun begins. The database is created from the command line. Type:

Docker pull WordPress docker checks whether word press and all dependent objects are installed. Otherwise, the docker hub website will automatically the zip archive file, extract it and install it on the system (pool). For docker, create an \

You are in business! This is a manual method and is best created strictly on the command line. See what you can do in a more programmatic way
whole Docker – use compose to set up text imprinting docker compose uses a configuration file to create a container, so it can be easily copied as needed. The configuration file described here is part of the official docker document. In other words, you must create a project directory to store the container and its configuration files. Ensure that docker compose is installed using the following command: Create docker compose using the load summary 7e40357dd6a40f0eb9b1dae0400cc82 text editor. Start the WordPress web site. A separate MySQL instance with YML files and volume mounts for data persistence. In the service section, create a WordPress database and define credentials to access mysql\u root\password, mysql\u user, and mysql\u password. Then, the docker hub will get the latest word press image, instruct docker to display content on port 8000, and connect to the WordPress database just created. See loading summary 293c2af427c657bd2941e6392c70b516: the docking volume db\u data will retain all updates to the database in WordPress. If there are yaml files in the project directory, run docker-composite up-d in the project directory. As with the manual version, the compose file performs the same operations as docker pull WordPress. That is, import the required image and start WordPress and the database container as follows: Load summary 02f2ce677bfa8b9d86bec1d1453a07a2 last step: run WordPress. After running compose, you may need to wait a few minutes. The WordPress site cannot be used immediately because the container is still initializing. If docker machine IP machine_vm is entered during the wait, the computer address is displayed. You can then open a browser and enter the results of the computer address command. http:\/\/MACHINE_VM_IP:8000 At this point, WordPress must be running on port 8000 on the docker host. You can complete the \
