ndongelo/centos-nginx-wordpress repository overview

⁠centos-nginx-wordpress

This repository contain a Dockerfile to build a data container image that mount DocumentRoot for nginx, and install wordpress in the directory and also mount it on the host machine, to create a niginx container I will use this image minhdanh/nginx-php7-fpm (it’s an image of nginx with php installed).

⁠Base Docker Image

• centos

⁠Use of this image

You can use this repository to create data-container witch will map on directory /usr/share/nginx/html and for nginx server /var/lib/mysql for mariadb.

⁠Prerequisites

#Creation of a new network called nginxarxa.

$ docker network create nginxarxa

First we need create a network that we will use while creating containers

$ docker create --name datacontainer --network nginxarxa ndongelo/centos-nginx-wordpress

Then we create a container with this image.

Here I am using orboan/dcsss-mariadb image to create a container based on mariadb here we create a
database for our wordpress.

⁠Docker run example:

With --name you can give a name to you container at container creation time.

With MYSQL_ROOT_PASSWORD enviroment variable you can set the mariadb root password at container creation time.

With MYSQL_DATABASE1, MYSQL_USER1, MYSQL_PASSWORD1 you can create a mysql db, user with all privileges upon this db, and its password, at container creation time.

You can also create up to 10 triplets (db, user, password) using MYSQL_DATABASEn, MYSQL_USERn, MYSQL_PASSWORDn environment variables, with n=1..10

3306:3306 maps the mariadb server

⁠docker run -itd -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE1=wordb -e MYSQL_USER1=aurel -e MYSQL_PASSWORD1=aurel --volumes-from datacontainer --network nginxarxa --name db orboan/dcsss-mariadb

We also use -d option for container to run in background and print container ID.

**$ docker run -itd -p 8080:80 --name nginx --network nginxarxa ndongelo/centos-nginx-php **

With --name you can give a name to you container at container creation time.

With -p 8080:80 Mapping the port 8080 of the host machine to port 80 of the container, it’s the port that nginx server use by default, and mapping volumes from datacontainer with --volumes-from datacontainer.

With this command we create on nginx based container with image wyveo/nginx-php-fpm (In this image nginx is installed with php and it's configured in way where **nginx work directory(DocumentRoot) would be /usr/share/nginx/html ** )

Then you can http://host-ip:80⁠ in your browser and while you setup your wordpress you should take in considration that in Database Host field you have to insert your localhost or host-ip with port 3306 and also you will use the same user and password that you created while creating mariadb container.

⁠script ( exercici3.sh )

You can run the following script to create a network for the containers and a create datacontainer with this image (ndongelo/centos-nginx-wordpress) which maps the nginx directory /usr/share/nginx/html/ and mariadb directory /var/lib/mysql and also runs nginx and mariadb containers.

#Creating a container named datacontainer with the image centos which is mapping volumes /data:/usr/share/nginx/html/ for nginx and /data:/var/lib/mysql (database for wordpress) for mariadb. docker create --name datacontainer -v /data:/usr/share/nginx/html/ -v /data:/var/lib/mysql centos

#Creation of a new network called wpnet. docker network create nginxarxa

#Create a mariadb-based container named db with image orboan/dcsss-mariadb using volumes of the datacontainer

docker run -itd -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE1=wordb -e MYSQL_USER1=aurel -e MYSQL_PASSWORD1=aurel --volumes-from datacontainer --network nginxarxa --name db orboan/dcsss-mariadb

#Create a container based on nginx called nginx with image minhdanh/nginx-php7-fpm using datacontainer volumes. docker run -itd -p 8080:80 --name nginx --network nginxarxa ndongelo/centos-nginx-php
