LAMP using Docker Part II

Putting the M in LAMP

In Part I we built a Dockerfile to generate the LAP part of a LAMP server.  Now, all we need to do is add instructions to a Dockerfile in order to install and start MySQL.

# MySQL Server.
# Version 0.1
FROM ubuntu:12.04
MAINTAINER Last Mile Synergy, LLC
 
RUN dpkg-divert --local --rename --add /sbin/initctl
RUN ln -s /bin/true /sbin/initctl
RUN apt-get update
RUN apt-get install -y mysql-server
RUN apt-get clean
 
RUN sed -i -e"s/^bind-address\s*=\s*127.0.0.1/bind-address = 0.0.0.0/" /etc/mysql/my.cnf
RUN /usr/sbin/mysqld & sleep 10s && echo "GRANT ALL ON *.* TO admin@'%' IDENTIFIED BY 'password' WITH GRANT OPTION; FLUSH PRIVILEGES" | mysql
 
EXPOSE 3306
 
CMD ["/usr/sbin/mysqld"]

Save the Dockerfile in its own directory and build the MySQL image with:

$ sudo docker build -rm -t MySQL .

Now we start a container from the image and then check what container ID is created:

$ sudo docker run -d MySQL
$ sudo docker ps
CONTAINER ID        IMAGE                      COMMAND                   CREATED                  STATUS                    PORTS              NAMES
d4d558ba4c83        MySQL:latest            /usr/sbin/mysqld           4 seconds ago           Up 4 seconds          3306/tcp            kickass_pike        
79f65558f236           apache-php:latest   /usr/sbin/apache2 -D   About an hour ago   Up About an hour    80/tcp                mad_pare    
 
Now we have Apache, PHP, and MySQL all running within Linux (aka LAMP).
