Docker, a software facilitating the utilization and creation of containers, proves instrumental in deploying WordPress. In this discussion, we explore the advantages of employing Docker and walk through the steps of installing WordPress.
Let’s commence.
Advantages of Utilizing Docker
Setting up WordPress necessitates a well-structured stack, such as LAMP (Linux, Apache, MySQL, PHP) or LEMP (Linux, Nginx, MySQL, PHP). The installation of these components can be time-intensive, limiting your ability to experiment with code. This is where Docker becomes invaluable.
Docker leverages containers to generate, deploy, and operate applications. Each container provides a self-contained environment for configuring your stack, libraries, and dependencies. Varied containers can host diverse configurations, allowing you to install WordPress with Apache in one container and Nginx in another. Container activation and deactivation are at your discretion. Utilizing tools like Docker Compose enables the seamless execution of multi-container applications.
- Versatility in Server Configurations
A distinctive advantage of Docker lies in its adaptability to configure diverse server stacks. Varied containers can support different server configurations, enabling the installation of WordPress with Apache in one container and Nginx in another. This tailoring accommodates specific preferences seamlessly.
- Optimized Resource Management
Docker containers exhibit lightweight characteristics and share the host OS kernel, optimizing resource utilization. This results in swift deployments and an environment that is both resource-efficient and scalable.
- Multi-Container Applications through Docker Compose
Docker Compose, a utility for delineating and executing multi-container Docker applications, amplifies the simplicity of overseeing your WordPress setup. Utilizing a straightforward docker-compose.yml file, you can specify the services, networks, and volumes for your WordPress environment.
- Installation Process Tailored for Users
The installation guide is crafted with user-friendliness in mind, ensuring accessibility for novices and seasoned users alike. The straightforward steps, coupled with Docker’s capabilities, streamline the establishment of a WordPress instance, making it an uncomplicated and efficient undertaking.
How to install WordPress with Docker
To establish your WordPress installation, only two containers and a Docker compose file are required.
Installing WordPress with Docker requires the presence of Docker, Docker-Compose, and a docker-compose.yml file on your server. To proceed with the installation, please follow these steps:
1. Install Docker Using the Official Repository:
If you are installing Docker for the first time, follow these steps to set up the Docker Repository. If you already have the Docker repository set up, skip to steps 5 & 6.
– Update the apt package index:
```bash
sudo apt-get update
```– To use a repository over HTTPS, install packages for apt:
```bash
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \Add Docker’s official GPG Key
software-properties-common
```
– Add Docker’s official GPG Key:
```bash
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
```
– Set up the stable repository:
```bash
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
```– To update the apt package index:
```bash
sudo apt-get update
``````bash
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
```– Then, install the latest version of Docker CE and containers:
```bash
sudo apt-get install docker-ce docker-ce-cli containerd.io
```2. Install Docker-Compose:
– Download the current stable release of Docker Compose:
```bash
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
```
- Apply executable permissions to the binary:
```bash
sudo chmod +x /usr/local/bin/docker-compose
```
3. Create a docker-compose.yml File:
To install WordPress, set up two containers (one for WordPress and one for the Database). Use a single docker-compose.yml file with the following content:
```yaml
version: '3'
services:
wordpress:
depends_on:
- db
image: wordpress:latest
volumes:
- wp_data:/var/www/html
ports:
- "80:80"
restart_policy:
condition: on-failure
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: my_wordpress_db_password
db:
image: mariadb
volumes:
- db_data:/var/lib/mysql
restart_policy:
condition: on-failure
environment:
MYSQL_ROOT_PASSWORD: my_db_root_password
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: my_wordpress_db_password
volumes:
wp_data:
db_data:
```
4. Prepare Docker-Compose:
Move the docker-compose.yml file to a location you can easily access (e.g., ~wordpress/docker-compose.yml). From that directory, run the following command:
“`bash
docker-compose up -d
“`
5. Start WordPress:
Your WordPress installation is now complete and ready to be set up. Access the setup page by visiting the IP address of your server.
FAQS
