Docker - Setting WordPress

Setting Up WordPress with Docker

In this chapter, we will look at how to set up WordPress using Docker. Docker is a useful tool. It helps us create, deploy, and manage applications in separate containers. Docker makes it easier to run applications like WordPress. It gives us a steady environment. This way, our website runs well no matter what the system is.

Learning how to set up WordPress in Docker is important for web development today. It helps with moving our projects around and growing them. We will explain the whole process. This includes what we need to do first, how to install Docker, how to create a Docker network, how to set up MySQL, and how to use Docker Compose for a smooth WordPress and MySQL setup.

For more information, we can check out other topics like Docker - Setting MySQL and Docker - Setting Ubuntu.

Introduction to Docker and WordPress

Docker is a strong platform. It helps us automate how we deploy applications in light and portable containers. This container technology works well for web apps like WordPress. WordPress needs many parts like a web server, database, and PHP runtime.

WordPress is a well-known content management system (CMS). It helps users create and manage websites easily. When we use Docker with WordPress, we can deploy it fast and keep it the same in different environments. This means our development, staging, and production setups will look alike.

Using Docker for WordPress has many benefits:

Isolation: Each app and its parts run in their own containers. This stops conflicts from happening.
Portability: Docker containers work on any machine that has Docker. This makes it easy to move apps around.
Scalability: We can easily scale containers to deal with more traffic. We just need to add more instances.

In this guide, we will learn how to set up WordPress with Docker. We will also configure containers for MySQL and other services. For more info on Docker’s benefits, check our article on Docker installation.

Prerequisites for Setting Up Docker and WordPress

Before we start setting up Docker and WordPress, we need to make sure our environment meets some important requirements.

Operating System:
- Docker works on many operating systems. This includes Windows, macOS, and most Linux versions like Ubuntu.
Docker Installation:
- We need to have Docker installed on our system. We can follow the steps in the official Docker installation guide.
Docker Compose:
- We also need to install Docker Compose. This tool helps us manage multiple containers easily. It is important for running WordPress and MySQL together. We can learn more about using Docker Compose.
Basic Command Line Knowledge:
- Knowing how to use the command line is very helpful. This skill helps us run Docker commands correctly.
System Resources:
- We should check that our computer has enough resources. We need enough CPU, RAM, and disk space to run WordPress and MySQL containers without problems.
Network Configuration:
- Understanding some basic networking ideas will help us set up Docker networking for WordPress.

By checking these requirements, we get ready to set up Docker and WordPress without issues. For more information on Docker, we can look at this guide on what Docker is.

Installing Docker on Your System

To set up WordPress with Docker, we first need to install Docker on our system. Docker gives us a stable place to run applications like WordPress. It helps us manage dependencies and configurations easily.

Installation Steps:

Update your package index:
```
sudo apt-get update
```

Install required packages:

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

Add Docker’s official GPG key:

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

Set up the stable repository:

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

Install Docker CE (Community Edition):

sudo apt-get update
sudo apt-get install docker-ce

Check if installation is successful:
```
sudo docker --version
```

After we finish these steps, Docker will be ready on our system. Then we can start setting up WordPress in containers. For more related setups, see Docker setting for Ubuntu.

Creating a Docker Network for WordPress

To set up WordPress with Docker, we need to create a special Docker network. This network helps containers talk to each other safe and easy. We will make a bridge network, which is the main type of network in Docker.

Steps to Create a Docker Network:

Open your terminal.
Run this command to create a network called wordpress-network:
```
docker network create wordpress-network
```
Check if the network is created by listing all Docker networks:
```
docker network ls
```

Benefits of Creating a Dedicated Network:

Isolation: This keeps your WordPress and MySQL containers separate from other containers.
Communication: It makes it easy for WordPress and MySQL containers to talk using their names instead of numbers.
Security: It makes it safer by limiting what other containers can see.

When we set up a Docker network, we prepare the way to set up the MySQL and WordPress containers the right way. This setup helps make our WordPress run better and safer on Docker. For a full guide on using Docker for many apps, check out Docker - Setting MySQL.

Setting Up MySQL Container for WordPress

To run WordPress in Docker, we need a MySQL database. We can set up a MySQL container using the official MySQL image from Docker Hub. Here is how we do it:

Pull the MySQL Image: First, we pull the MySQL Docker image. We can choose the version we want to use.
```
docker pull mysql:5.7
```
Run the MySQL Container: Next, we run the MySQL container with this command. Make sure to set the environment variables for MYSQL_ROOT_PASSWORD, MYSQL_DATABASE, MYSQL_USER, and MYSQL_PASSWORD.
```
docker run --name wordpress-db -e MYSQL_ROOT_PASSWORD=yourpassword -e MYSQL_DATABASE=wordpress -e MYSQL_USER=wpuser -e MYSQL_PASSWORD=wppassword -p 3306:3306 -d mysql:5.7
```
In this command:
- --name wordpress-db gives a name to our container.
- -e sets the environment variables for MySQL.
- -p 3306:3306 links the container’s MySQL port to our host.
Verify the Container: We can check if the MySQL container is running by using:
```
docker ps
```

This MySQL setup helps our WordPress container to connect without problems. For more Docker setup, we can look at Docker - Setting MySQL.

Configuring WordPress Container

To configure the WordPress container, we need to set up some important environment variables. We also link it to the MySQL container. We can do this using the docker run command or by using a docker-compose.yml file.

If we use docker run, the command looks like this:

docker run -d --name wordpress \
  --network wordpress-network \
  -e WORDPRESS_DB_HOST=mysql-container \
  -e WORDPRESS_DB_USER=wp_user \
  -e WORDPRESS_DB_PASSWORD=wp_password \
  -e WORDPRESS_DB_NAME=wordpress_db \
  -p 8080:80 \
  wordpress

Key Environment Variables:

WORDPRESS_DB_HOST: This is the name of the MySQL container.
WORDPRESS_DB_USER: This is the MySQL user for WordPress database.
WORDPRESS_DB_PASSWORD: This is the password for the MySQL user.
WORDPRESS_DB_NAME: This is the name of the database for WordPress.

If we are using Docker Compose, we can put the WordPress settings in our docker-compose.yml file like this:

version: "3.1"

services:
  wordpress:
    image: wordpress
    environment:
      WORDPRESS_DB_HOST: mysql-container
      WORDPRESS_DB_USER: wp_user
      WORDPRESS_DB_PASSWORD: wp_password
      WORDPRESS_DB_NAME: wordpress_db
    ports:
      - 8080:80
    networks:
      - wordpress-network

networks:
  wordpress-network:
    driver: bridge

This setup makes the WordPress environment work well. It lets WordPress talk to the MySQL container. For more information on how to set up MySQL, check Setting Up MySQL Container for WordPress.

Connecting WordPress to MySQL

We want to connect WordPress to a MySQL database in a Docker container. To do this, we need to make some important settings. This helps WordPress talk to MySQL. It can then store and get data.

Environment Variables: We need to set the right environment variables in the WordPress container. These variables are:
- WORDPRESS_DB_HOST: This is the hostname of the MySQL database. It usually looks like mysql:3306 when we use Docker Compose.
- WORDPRESS_DB_USER: This is the MySQL user. It can be root or another user we create.
- WORDPRESS_DB_PASSWORD: This is the password for the MySQL user.
- WORDPRESS_DB_NAME: This is the name of the WordPress database.
Here is an example of Docker Compose settings:
```
services:
  wordpress:
    image: wordpress
    environment:
      WORDPRESS_DB_HOST: mysql:3306
      WORDPRESS_DB_USER: root
      WORDPRESS_DB_PASSWORD: examplepassword
      WORDPRESS_DB_NAME: wordpress_db
```
Database Creation: We need to make sure that the database we wrote in WORDPRESS_DB_NAME exists in the MySQL container. We can create it using a MySQL client or with Docker commands.
Network Configuration: We should make sure that both WordPress and MySQL containers are in the same Docker network. This lets them talk to each other.

For more help, we can check the Docker - Setting WordPress guide. It has more details and examples. Connecting WordPress to MySQL is very important for how the app works and for managing data.

Using Docker Compose for WordPress Setup

We can use Docker Compose to make setting up multi-container apps easier. It is great for deploying WordPress with a MySQL database. By writing the services, networks, and volumes in one docker-compose.yml file, we can easily handle our WordPress setup.

Here is a simple example of a docker-compose.yml file to set up WordPress with MySQL:

version: "3.8"

services:
  wordpress:
    image: wordpress:latest
    restart: always
    ports:
      - "8000:80"
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_USER: user
      WORDPRESS_DB_PASSWORD: password
      WORDPRESS_DB_NAME: wordpress
    volumes:
      - wordpress_data:/var/www/html

  db:
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: root_password
      MYSQL_DATABASE: wordpress
      MYSQL_USER: user
      MYSQL_PASSWORD: password
    volumes:
      - db_data:/var/lib/mysql

volumes:
  wordpress_data:
  db_data:

Key Configurations:

wordpress: This defines the WordPress service. It connects to the MySQL database.
db: This sets up the MySQL container with the needed environment variables.
Volumes: This helps keep data safe for both WordPress and MySQL.

To run the setup, we need to type:

docker-compose up -d

This command will start the containers in detached mode. After it installs, we can reach WordPress by going to http://localhost:8000 in our web browser.

If we want to change things around, we can look at more Docker Compose settings to make our WordPress setup better.

Deploying WordPress and MySQL Containers

We can deploy WordPress and MySQL containers using Docker. We can use the Docker CLI or Docker Compose for this. This process needs us to create and run two separate containers. One will be for WordPress and another will be for MySQL. We need to make sure they can talk to each other.

If we use the Docker CLI, we start by pulling the required images. We can do this with these commands:

docker pull wordpress:latest
docker pull mysql:5.7

Next, we create a Docker network. This helps the containers to communicate:

docker network create wordpress-network

Now, we deploy the MySQL container. We can do this with the command below:

docker run --name mysql-container --network wordpress-network -e MYSQL_ROOT_PASSWORD=root_password -e MYSQL_DATABASE=wordpress_db -d mysql:5.7

Then, we deploy the WordPress container. We can use this command:

docker run --name wordpress-container --network wordpress-network -e WORDPRESS_DB_HOST=mysql-container -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=root_password -p 8080:80 -d wordpress:latest

This setup configures the database host, user, and password for WordPress. It links WordPress to the MySQL container. To check the status of our containers, we can use:

docker ps

Now, we can access our WordPress site by going to http://localhost:8080 in our web browser. This setup gives us a good environment to run WordPress with MySQL in Docker. If we want a simpler way to manage our containers, we can use Docker Compose.

Accessing WordPress in Your Browser

After we set up our WordPress and MySQL containers with Docker, we can access our WordPress site in a web browser easily. Here are the steps we need to follow:

Find the Docker Host IP Address: If we run Docker on our local machine, it is usually http://localhost. If we use Docker on a remote server, we need to use the server’s IP address.
Port Mapping: We must check that we mapped the right ports in our Docker settings. The default port for WordPress is 80. If we chose a different port when setting up, we should use that one (for example, http://localhost:8080).
Open Your Browser: We open our web browser and type the address like this:
```
http://localhost:80
```
or we can change localhost to our server’s IP address.
WordPress Installation Page: Now, we should see the WordPress installation page. We can follow the instructions on the screen to finish the setup. We will select our language, enter database details, and make an admin account.
Troubleshooting: If the page does not show up, we must check if our Docker containers are running. We can do that by typing:
```
docker ps
```
We need to make sure both WordPress and MySQL containers are running.

By following these steps, we can easily access our WordPress site in a Docker setup. For more help with Docker settings, we can look at Docker - Setting MySQL.

Docker - Setting WordPress - Full Example

We can set up WordPress using Docker. We will use Docker Compose to easily deploy WordPress and MySQL containers. Below is a simple example of how to set up and run WordPress in Docker.

Step 1: Create a `docker-compose.yml` File

First, we need to create a new folder for our WordPress project. Then, we go into this folder. Inside this folder, we create a file called docker-compose.yml. We will add the following content to this file:

version: "3.8"
services:
  db:
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: example
      MYSQL_DATABASE: wordpress
      MYSQL_USER: user
      MYSQL_PASSWORD: userpassword
    volumes:
      - db_data:/var/lib/mysql

  wordpress:
    image: wordpress:latest
    restart: always
    ports:
      - "8000:80"
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_USER: user
      WORDPRESS_DB_PASSWORD: userpassword
      WORDPRESS_DB_NAME: wordpress
    volumes:
      - wordpress_data:/var/www/html

volumes:
  db_data:
  wordpress_data:

Step 2: Start the Containers

Next, we need to run a command in the terminal from our project folder. We run this command:

docker-compose up -d

This command pulls the images we need and starts the containers in the background.

Step 3: Access WordPress

After the containers are running, we can access our WordPress site. We go to http://localhost:8000 in our web browser. We follow the instructions on the screen to finish the WordPress installation.

This example shows how easy it is to set up WordPress with Docker. For more detailed info, we can check other resources on Docker networking and Docker volumes.
