Wordpress 5.7.2 + Docker
Just the file wp-config.php is the only difference with the official version https://wordpress.org/wordpress-5.7.2.tar.gz
- docker
- docker-compose
The following command will deploy tha database, import the .sql and start the wordpress:
docker-compose up -d
- build
- variables
- run
docker build -t wordpress:5.7.2 .
Traditionally wordpress configurations are performed with manuall modifications in wp-config.php file. With docker this is not acceptable anymore. This docker version use getenv() instead hardcoded values in wp-config. This made it possible to configure the entire wordpress with environment variables. If you find more low level convigurations, I advice to use getenv() and pass the value as environment variable. Currently these are the required variables:
| name | description |
|---|---|
| WP_SITEURL | ip or domain, when you are deploying to a real server |
| WP_HOME | ip or domain, when you are deploying to a real server |
| ENABLE_HTTPS | "true" or "false". Used when your ip or domain has a valid https certificate. |
| DB_HOST | mysql database host. If your db use another port instead 3306, append it to the host 10.10.10.20:3307 |
| DB_USER | mysql database user |
| DB_PASSWORD | password related to the mysql user |
| DB_NAME | database name |
| AUTH_KEY | random value |
| SECURE_AUTH_KEY | random value |
| NONCE_KEY | random value |
| LOGGED_IN_KEY | random value |
| AUTH_SALT | random value |
| SECURE_AUTH_SALT | random value |
| LOGGED_IN_SALT | random value |
| NONCE_SALT | random value |
| WP_DEBUG | "true" or "false". Used to find low level errors in wordpress |
| DISABLE_WP_CRON | "true" or "false". Used to enable the cron |
Use this command $(hostname -I| awk '{printf $1}') to get the ip of the host in which database is running. If you are using a remote mysql (gcp, aws, azure, etc) set the public domain or ip in DB_HOST var
export RANDOM_KEY=$(uuidgen)
docker run -d --name wordpress -it --rm -p 80:80 \
-e DB_HOST=10.10.10.10:3306 \
-e DB_USER=root \
-e DB_PASSWORD=secret \
-e DB_NAME=wordpress \
-e AUTH_KEY=$RANDOM_KEY \
-e SECURE_AUTH_KEY=$RANDOM_KEY \
-e NONCE_KEY=$RANDOM_KEY \
-e LOGGED_IN_KEY=$RANDOM_KEY \
-e AUTH_SALT=$RANDOM_KEY \
-e SECURE_AUTH_SALT=$RANDOM_KEY \
-e LOGGED_IN_SALT=$RANDOM_KEY \
-e NONCE_SALT=$RANDOM_KEY \
-e WP_DEBUG=true \
-e DISABLE_WP_CRON=true \
-e TZ=America/Lima wordpress:5.7.2
Required variables could be configured remotely to avoid shell access.
docker run -d --name wordpress -it --rm -p 80:80 \
-e CONFIGURATOR_GET_VARIABLES_FULL_URL=http://foo.com/api/v1/variables?application=wordpress \
-e CONFIGURATOR_AUTH_HEADER=apiKey:changeme \
-e TZ=America/Lima wordpress:5.7.2
Finally go to http://localhost and enter these credentials:
- user: admin
- password: 123456
Don't forget to change the password.
- Low level errors in /var/log/apache2/error.log
- Set your preferred timezone in TZ variable
- On docker compose step, add a volume to mysql in order to save the data:
- /my/databases/mysqldata:/var/lib/mysql, because mysql with docker is just for testing purposes. For real environment, use some mysql service (aws, gcp, azure, ect)
