wordpress container sample
docker wordpress
start a docker container with wordpress with port mapping to access from local machine
docker pull wordpress
# multiple options to start the container, more details here [https://hub.docker.com/_/wordpress/](https://hub.docker.com/_/wordpress/)
# docker run --name some-wordpress --network some-network -d wordpress`
# docker run --name antonio-wordpress --network bridge -d wordpress`
docker run --name antonio-wordpress --network wordpress-network -p 8080:80 -d wordpress
# http://127.0.0.1:8080/
Database name
Database username
Database password
Database host
Table prefix (if you want to run more than one WordPress in a single database)
This information is being used to create a wp-config.php file.
If for any reason this automatic file creation does not work, do not worry.
All this does is fill in the database information to a configuration file.
You may also simply open wp-config-sample.php in a text editor, fill in your information, and save it as wp-config.php.

database
starting the database container with MariaDB for wordpress
https://hub.docker.com/_/mariadb
https://www.freecodecamp.org/news/tag/docker/
https://resources.infosecinstitute.com/topics/hacking/
This will will start the database with port mapping, so you can access directly from your machine.
added the --network wordpress-network to specify the network that will share with the wordpress and mariadb container
docker run --detach --name antonio-mariadb -p 3306:3306 --network wordpress-network --env MARIADB_USER=antonio-user --env MARIADB_PASSWORD=antonio-super-cool-secret --env MARIADB_ROOT_PASSWORD=rootantonio-super-cool-secret mariadb:latest
without port mapping (default)
docker run --detach --name antonio-mariadb --env MARIADB_USER=antonio-user --env MARIADB_PASSWORD=antonio-super-cool-secret --env MARIADB_ROOT_PASSWORD=rootantonio-super-cool-secret mariadb:latest
docker run --detach --name antonio-mariadb --env MARIADB_USER=antonio-user --env MARIADB_PASSWORD=antonio-super-cool-secret --env MARIADB_ROOT_PASSWORD=rootantonio-super-cool-secret mariadb:latest
The following command starts another MariaDB container instance and runs the mysql command line client against your original mariadb container, allowing you to execute SQL statements against your database instance
With this, we can create the database and user for the wordpress website
docker run -it --rm mariadb mysql -h172.17.0.2 -uantonio-user -p
docker run -it --rm --network wordpress-network mariadb mysql -h127.0.0.1 -uroot -p
CREATE DATABASE wordpress;
CREATE USER 'wpdb_user'@'localhost' IDENTIFIED BY 'SQHicxbcZ4wp7QSA5!RQZad$&V5UWVL2vFJW';
GRANT ALL PRIVILEGES ON wordpress.* TO 'wpdb_user'@'localhost';
SHOW DATABASES;
USE wordpress
USE mysql;
SHOW TABLES;
SHOW COLUMNS FROM user;
SELECT Host,User,Password,Select_priv,Grant_priv FROM user WHERE User="wpdb_user";
docker network
with the docker network ls we can list the docker network interfaces
with the docker network inspect NET-WORK-ID we can see what container are linked to that network
## list docker images
docker images
docker image ls
## list docker containers
docker container ls
docker container ls -a
example
docker container ls

connect to the container on the specific network
docker run -it --rm --network wordpress-network mariadb mysql -h172.18.0.2 -uroot -p
docker run --name antonio-wordpress --network wordpress-network -p 8080:80 -d wordpress
jump into the container to check the configurations
docker container exec -it antonio-wordpress /bin/bash
# or
docker container exec -it antonio-mariadb /bin/bash
update if needed, not best practices, should be updated and create image, then start from image
apt update && apt upgrade -y
install net-tools to help troubleshooting with network commands
apt install net-tools netcat vim
netstat -pantl
alias ll='ls -alhF --group-directories-first --color=always'
testing connection from antonio-wordpress to antonio-mariadb
test the mysql wp username, permissions and password
