Mysql Dockerfile --> Docker container. 🐧🐳

Spinup Mysql Docker Container✨

Spinning a MySQL DB on docker is easier than installing and configuring it on a raw server and can spin up the MYSQL container within a few mins.

We can avoid MySQL secure installations, cnf configurations, and other setups that needed to be composed before starting the DB.

We can classify this into 3 stages,

1) Dockerfile creation

2) Docker image creation

3) Docker container creation

1) Create the docker file

A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image.
First, create a docker file.

# vim Dockerfile

Refer to the Dockerfile below to spinup MySQL 8.0

FROM mysql:8.0.23    
MAINTAINER vk@gmail.com
COPY my.cnf /etc/mysql/my.cnf  
ENV MYSQL_ROOT_PASSWORD mypassword 
ENV MYSQL_USER bob  
ENV MYSQL_DATABASE DATA123 
ENV MYSQL_PASSWORD new_password 
RUN mkdir /var/lib/mysql-files
RUN touch /var/log/mysqld.log
RUN chown mysql:mysql /var/log/mysqld.log
EXPOSE 3306

Explanation:

FROM mysql:8.0.23 --> Choosing base image as mysql.
MAINTAINER vk@gmail.com --> Author field.
COPY my.cnf /etc/mysql/my.cnf --> Need to setup the cnf file as for your configuration and copy the .cnf file to the directory where Dockerfile is located.
ENV MYSQL_ROOT_PASSWORD mypassword --> 'mypassword' will be the password for root user
ENV MYSQL_USER bob --> Create a additional mysql user named 'bob' if needed
ENV MYSQL_DATABASE DATA123 --> Creating database 'DATA123'
ENV MYSQL_PASSWORD new_password --> Password for mysql users.
RUN mkdir /var/lib/mysql-files --> Create mysql lib file directory.
RUN touch /var/log/mysqld.log --> Creating mysql log file to write the mysql logs.
RUN chown mysql:mysql /var/log/mysqld.log --> Ownership change for that file.
EXPOSE 3306 --> Assigning container port.

2) Docker image creation

Move to the directory where the Dockerfile is located, then run the below command to create the docker image.

# docker build -t image_name .

3) Finally create docker container.

# docker images // to view the image id

# docker run -d -p host_port:container_port --name {container-name} {image id}

eg : # docker run -d -p 3306:3306 --name mydatabase 037da8935fa

check the status of the container,
# docker ps -a

Cheers!🥂✨
