# WordPress for Intel packaged by Bitnami
## What is WordPress for Intel?
> WordPress for Intel is the most popular blogging application combined with cryptography acceleration for 3rd gen Xeon Scalable Processors (Ice Lake) to get a breakthrough performance improvement.
[Overview of WordPress for Intel](http://www.wordpress.org/)
Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.
## TL;DR
```console
$ curl -sSL https://raw.githubusercontent.com/bitnami/containers/main/bitnami/wordpress-intel/docker-compose.yml > docker-compose.yml
$ docker-compose up -d
```
**Warning**: This quick setup is only intended for development environments. You are encouraged to change the insecure default credentials and check out the available configuration options in the [Environment Variables](#environment-variables) section for a more secure deployment.
## Why use Intel optimized containers
Encryption is becoming pervasive with most organizations increasingly adopting encryption for application execution, data in flight, and data storage. Intel® 3rd gen Xeon® Scalable Processor (Ice Lake) cores and architecture, offers several new instructions for encryption acceleration. These new instructions, coupled with algorithmic and software innovations, deliver breakthrough performance for the industry's most widely deployed cryptographic ciphers.
This solution accelerates the processing of the Transport Layer Security (TLS) significantly by using built-in Intel crypto acceleration included in the latest Intel 3rd gen Xeon Scalable Processor (Ice Lake). For more information, refer to [Intel’s documentation](https://software.intel.com/content/www/us/en/develop/articles/wordpress-tuning-guide-on-xeon-systems.html).
It requires a 3rd gen Xeon Scalable Processor (Ice Lake) to get a breakthrough performance improvement.
## Why use Bitnami Images?
- Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
- With Bitnami images the latest bug fixes and features are available as soon as possible.
- Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
- All our images are based on [minideb](https://github.com/bitnami/minideb) a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
- All Bitnami images available in Docker Hub are signed with [Docker Content Trust (DCT)](https://docs.docker.com/engine/security/trust/content_trust/). You can use `DOCKER_CONTENT_TRUST=1` to verify the integrity of the images.
- Bitnami container images are released on a regular basis with the latest distribution packages available.
# How to deploy WordPress for Intel in Kubernetes?
Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the [Bitnami WordPress for Intel Chart GitHub repository](https://github.com/bitnami/charts/tree/master/bitnami/wordpress-intel).
Bitnami containers can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.
## Why use a non-root container?
Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers [in our docs](https://docs.bitnami.com/tutorials/work-with-non-root-containers/).
## Supported tags and respective `Dockerfile` links
Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags [in our documentation page](https://docs.bitnami.com/tutorials/understand-rolling-tags-containers/).
- [`6`, `6-debian-11`, `6.0.1`, `6.0.1-debian-11-r9`, `latest` (6/debian-11/Dockerfile)](https://github.com/bitnami/containers/blob/main/bitnami/wordpress/6/debian-11/Dockerfile)
Subscribe to project updates by watching the [bitnami/containers GitHub repo](https://github.com/bitnami/containers).
## Get this image
The recommended way to get the Bitnami WordPress for Intel Docker Image is to pull the prebuilt image from the [Docker Hub Registry](https://hub.docker.com/r/bitnami/wordpress-intel).
```console
$ docker pull bitnami/wordpress-intel:latest
```
To use a specific version, you can pull a versioned tag. You can view the [list of available versions](https://hub.docker.com/r/bitnami/wordpress/tags/) in the Docker Hub Registry.
```console
$ docker pull bitnami/wordpress-intel:[TAG]
```
If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the `docker build` command. Remember to replace the `APP`, `VERSION` and `OPERATING-SYSTEM` path placeholders in the example command below with the correct values.
```console
$ git clone https://github.com/bitnami/containers.git
$ cd bitnami/APP/VERSION/OPERATING-SYSTEM
$ docker build -t bitnami/APP:latest .
```
## How to use this image
WordPress for Intel requires access to a MySQL or MariaDB database to store information. We'll use the [Bitnami Docker Image for MariaDB](https://github.com/bitnami/containers/tree/main/bitnami/mariadb) for the database requirements.
### Run the application using Docker Compose
The main folder of this repository contains a functional [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/wordpress-intel/docker-compose.yml) file. Run the application using it as shown below:
```console
$ curl -sSL https://raw.githubusercontent.com/bitnami/containers/main/bitnami/wordpress-intel/docker-compose.yml > docker-compose.yml
$ docker-compose up -d
```
### Using the Docker Command Line
If you want to run the application manually instead of using `docker-compose`, these are the basic steps you need to run:
#### Step 1: Create a network
```console
$ docker network create wordpress-network
```
#### Step 2: Create a volume for MariaDB persistence and create a MariaDB container
```console
$ docker volume create --name mariadb_data
$ docker run -d --name mariadb \
--env ALLOW_EMPTY_PASSWORD=yes \
--env MARIADB_USER=bn_wordpress \
--env MARIADB_PASSWORD=bitnami \
--env MARIADB_DATABASE=bitnami_wordpress \
--network wordpress-network \
--volume mariadb_data:/bitnami/mariadb \
bitnami/mariadb:latest
```
#### Step 3: Create volumes for WordPress for Intel persistence and launch the container
```console
$ docker volume create --name wordpress_data
$ docker run -d --name wordpress \
-p 8080:8080 -p 8443:8443 \
--env ALLOW_EMPTY_PASSWORD=yes \
--env WORDPRESS_DATABASE_USER=bn_wordpress \
--env WORDPRESS_DATABASE_PASSWORD=bitnami \
--env WORDPRESS_DATABASE_NAME=bitnami_wordpress \
--network wordpress-network \
--volume wordpress_data:/bitnami/wordpress \
bitnami/wordpress-intel:latest
```
Access your application at `http://your-ip/`
## Persisting your application
If you remove the container all your data will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.
For persistence you should mount a directory at the `/bitnami/wordpress` path. If the mounted directory is empty, it will be initialized on the first run. Additionally you should [mount a volume for persistence of the MariaDB data](https://github.com/bitnami/containers/blob/main/bitnami/mariadb#persisting-your-database).
The above examples define the Docker volumes named `mariadb_data` and `wordpress_data`. The WordPress for Intel application state will persist as long as volumes are not removed.
To avoid inadvertent removal of volumes, you can [mount host directories as data volumes](https://docs.docker.com/engine/tutorials/dockervolumes/). Alternatively you can make use of volume plugins to host the volume data.
### Mount host directories as data volumes with Docker Compose
This requires a minor change to the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/wordpress/docker-compose.yml) file present in this repository:
```diff
mariadb:
...
volumes:
- - 'mariadb_data:/bitnami/mariadb'
+ - /path/to/mariadb-persistence:/bitnami/mariadb
...
wordpress:
...
volumes:
- - 'wordpress_data:/bitnami/wordpress'
+ - /path/to/wordpress-persistence:/bitnami/wordpress
...
-volumes:
- mariadb_data:
- driver: local
- wordpress_data:
- driver: local
```
> NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID `1001`.
### Mount host directories as data volumes using the Docker command line
#### Step 1: Create a network (if it does not exist)
```console
$ docker network create wordpress-network
```
#### Step 2. Create a MariaDB container with host volume
```console
$ docker run -d --name mariadb \
--env ALLOW_EMPTY_PASSWORD=yes \
--env MARIADB_USER=bn_wordpress \
--env MARIADB_PASSWORD=bitnami \
--env MARIADB_DATABASE=bitnami_wordpress \
--network wordpress-network \
--volume /path/to/mariadb-persistence:/bitnami/mariadb \
bitnami/mariadb:latest
```
> NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID `1001`.
#### Step 3. Create the WordPress for Intel container with host volumes
```console
$ docker run -d --name wordpress \
-p 8080:8080 -p 8443:8443 \
--env ALLOW_EMPTY_PASSWORD=yes \
--env WORDPRESS_DATABASE_USER=bn_wordpress \
--env WORDPRESS_DATABASE_PASSWORD=bitnami \
--env WORDPRESS_DATABASE_NAME=bitnami_wordpress \
--network wordpress-network \
--volume /path/to/wordpress-persistence:/bitnami/wordpress \
bitnami/wordpress-intel:latest
```
> NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID `1001`.
## Configuration
### Environment variables
When you start the WordPress for Intel image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the `docker run` command line. Please note that some variables are only considered when the container is started for the first time. If you want to add a new environment variable:

##### SMTP configuration using a Gmail account
This would be an example of SMTP configuration using a Gmail account:
- Modify the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/wordpress/docker-compose.yml) file present in this repository:
```yaml
wordpress:
...
environment:
- WORDPRESS_DATABASE_USER=bn_wordpress
- WORDPRESS_DATABASE_NAME=bitnami_wordpress
- ALLOW_EMPTY_PASSWORD=yes
- WORDPRESS_SMTP_HOST=smtp.gmail.com
- WORDPRESS_SMTP_PORT=587
- WORDPRESS_SMTP_USER=your_email@gmail.com
- WORDPRESS_SMTP_PASSWORD=your_password
...
```
- For manual execution:
```console
$ docker run -d --name wordpress -p 80:8080 -p 443:8443 \
--env WORDPRESS_DATABASE_USER=bn_wordpress \
--env WORDPRESS_DATABASE_NAME=bitnami_wordpress \
--env WORDPRESS_SMTP_HOST=smtp.gmail.com \
--env WORDPRESS_SMTP_PORT=587 \
--env WORDPRESS_SMTP_USER=your_email@gmail.com \
--env WORDPRESS_SMTP_PASSWORD=your_password \
--network wordpress-tier \
--volume /path/to/wordpress-persistence:/bitnami \
bitnami/wordpress-intel:latest
```
##### Connect WordPress for Intel container to an existing database
The Bitnami WordPress for Intel container supports connecting the WordPress for Intel application to an external database. This would be an example of using an external database for WordPress for Intel.
- Modify the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/wordpress/docker-compose.yml) file present in this repository:
```diff
wordpress:
...
environment:
- - WORDPRESS_DATABASE_HOST=mariadb
+ - WORDPRESS_DATABASE_HOST=mariadb_host
- WORDPRESS_DATABASE_PORT_NUMBER=3306
- WORDPRESS_DATABASE_NAME=wordpress_db
- WORDPRESS_DATABASE_USER=wordpress_user
- - ALLOW_EMPTY_PASSWORD=yes
+ - WORDPRESS_DATABASE_PASSWORD=wordpress_password
...
```
- For manual execution:
```console
$ docker run -d --name wordpress\
-p 8080:8080 -p 8443:8443 \
--network wordpress-network \
--env WORDPRESS_DATABASE_HOST=mariadb_host \
--env WORDPRESS_DATABASE_PORT_NUMBER=3306 \
--env WORDPRESS_DATABASE_NAME=wordpress_db \
--env WORDPRESS_DATABASE_USER=wordpress_user \
--env WORDPRESS_DATABASE_PASSWORD=wordpress_password \
--volume wordpress_data:/bitnami/wordpress \
bitnami/wordpress-intel:latest
```
In case the database already contains data from a previous WordPress for Intel installation, you need to set the variable `WORDPRESS_SKIP_BOOTSTRAP` to `yes`. Otherwise, the container would execute the installation wizard and could modify the existing data in the database. Note that, when setting `WORDPRESS_SKIP_BOOTSTRAP` to `yes`, values for environment variables such as `WORDPRESS_USERNAME`, `WORDPRESS_PASSWORD` or `WORDPRESS_EMAIL` will be ignored. Make sure that, in this imported database, the table prefix matches the one set in `WORDPRESS_TABLE_PREFIX`.
## WP-CLI tool
The Bitnami WordPress for Intel container includes the command line interface **wp-cli** that can help you to manage and interact with your WP sites. To run this tool, please note you need use the proper system user, **daemon**.
This would be an example of using **wp-cli** to display the help menu:
* Using `docker-compose` command:
```console
$ docker-compose exec wordpress wp help
```
* Using `docker` command:
```console
$ docker exec wordpress wp help
```
Find more information about parameters available in the tool in the [official documentation](https://make.wordpress.org/cli/handbook/config/).
## Logging
The Bitnami WordPress for Intel Docker image sends the container logs to `stdout`. To view the logs:
```console
$ docker logs wordpress
```
Or using Docker Compose:
```console
$ docker-compose logs wordpress
```
You can configure the containers [logging driver](https://docs.docker.com/engine/admin/logging/overview/) using the `--log-driver` option if you wish to consume the container logs differently. In the default configuration docker uses the `json-file` driver.
## Maintenance
### Backing up your container
To backup your data, configuration and logs, follow these simple steps:
#### Step 1: Stop the currently running container
```console
$ docker stop wordpress
```
Or using Docker Compose:
```console
$ docker-compose stop wordpress
```
#### Step 2: Run the backup command
We need to mount two volumes in a container we will use to create the backup: a directory on your host to store the backup in, and the volumes from the container we just stopped so we can access the data.
```console
$ docker run --rm -v /path/to/wordpress-backups:/backups --volumes-from wordpress busybox \
cp -a /bitnami/wordpress /backups/latest
```
### Restoring a backup
Restoring a backup is as simple as mounting the backup as volumes in the containers.
For the MariaDB database container:
```diff
$ docker run -d --name mariadb \
...
- --volume /path/to/mariadb-persistence:/bitnami/mariadb \
+ --volume /path/to/mariadb-backups/latest:/bitnami/mariadb \
bitnami/mariadb:latest
```
For the WordPress for Intel container:
```diff
$ docker run -d --name wordpress \
...
- --volume /path/to/wordpress-persistence:/bitnami/wordpress \
+ --volume /path/to/wordpress-backups/latest:/bitnami/wordpress \
bitnami/wordpress-intel:latest
```
### Upgrade this image
Bitnami provides up-to-date versions of MariaDB and WordPress for Intel, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. We will cover here the upgrade of the WordPress for Intel container. For the MariaDB upgrade see https://github.com/bitnami/containers/tree/main/bitnami/mariadb#upgrade-this-image
The `bitnami/wordpress-intel:latest` tag always points to the most recent release. To get the most recent release you can simple repull the `latest` tag from the Docker Hub with `docker pull bitnami/wordpress-intel:latest`. However it is recommended to use [tagged versions](https://hub.docker.com/r/bitnami/wordpress-intel/tags/).
#### Step 1: Get the updated image
```console
$ docker pull bitnami/wordpress-intel:latest
```
#### Step 2: Stop the running container
Stop the currently running container using the command
```console
$ docker-compose stop wordpress
```
#### Step 3: Take a snapshot of the application state
Follow the steps in [Backing up your container](#backing-up-your-container) to take a snapshot of the current application state.
#### Step 4: Remove the currently running container
Remove the currently running container by executing the following command:
```console
docker-compose rm -v wordpress
```
#### Step 5: Run the new image
Update the image tag in `docker-compose.yml` and re-create your container with the new image:
```console
$ docker-compose up -d
```
## Customize this image
The Bitnami WordPress for Intel Docker image is designed to be extended so it can be used as the base image for your custom web applications.
### Extend this image
Before extending this image, please note there are certain configuration settings you can modify using the original image:
- Settings that can be adapted using environment variables. For instance, you can change the port used by NGINX for HTTP setting the environment variable `NGINX_HTTP_PORT_NUMBER`.
- [Adding custom server blocks](#adding-custom-server-blocks).
- [Replacing the 'nginx.conf' file](#full-configuration).
- [Using custom SSL certificates](#using-custom-ssl-certificates).
If your desired customizations cannot be covered using the methods mentioned above, extend the image. To do so, create your own image using a Dockerfile with the format below:
```Dockerfile
FROM bitnami/wordpress-intel
## Put your customizations below
...
```
- Modify the NGINX configuration file
- Modify the ports used by NGINX
- Change the user that runs the container
```Dockerfile
FROM bitnami/nginx
### Change user to perform privileged actions
USER 0
### Install 'vim'
RUN install_packages vim
### Revert to the original non-root user
USER 1001
### Modify 'worker_connections' on NGINX config file to '512'
RUN sed -i -r "s#(\s+worker_connections\s+)[0-9]+;#\1512;#" /opt/bitnami/nginx/conf/nginx.conf
### Modify the ports used by NGINX by default
ENV NGINX_HTTP_PORT_NUMBER=8181 # It is also possible to change this environment variable at runtime
EXPOSE 8181 8143
### Modify the default container user
USER 1002
```
Based on the extended image, you can update the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/wordpress/docker-compose.yml) file present in this repository to add other features:
```diff
wordpress:
- image: bitnami/wordpress-intel:latest
+ build: .
ports:
- - '80:8080'
- - '443:8443'
+ - '80:8181'
+ - '443:8143'
environment:
+ - PHP_MEMORY_LIMIT=512m
...
```
