MYSQL Server Singularity Container

A mysql:8.0.28 docker image package to be ran on singularity containerization solution.

Initialization

Building or Downloading the image (mysql.sif)

To start, build the singularity image with the command below which will store it as mysql.sif:

sudo singularity build mysql.sif mysql.def

or

singularity pull --arch amd64 library://synicix/walkerlab/mysql.sif:latest

Starting Singularity Container for the First Time

First we need to create the apporiate folders to store the /var/lib/mysql data directory and the /var/lib/run directory. Simply run these these commands under the folder where you want to stored them:

mkdir -p ./var/lib/mysql
mkdir -p ./var/run/mysqld

Note that there is also a default my.cnf that is provided in this repo. You can modify it to your liking and it will be bind into the container in the appropriate location

Start the server with the correct files binding via:

singularity instance start --bind <path_to_var_lib_mysql>:/var/lib/mysql/ --bind <path_to_var_run_mysqld>:/var/run/mysqld/ --bind <path_to_my.cnf>:/etc/mysql/my.cnf mysql.sif mysql

Logging in root requires to you extract the password that was generated for you during the initial start up:

cat ~/.singularity/instances/logs/<host_name>/<username>/mysql.err | grep "A temporary password is generated for root@localhost"

Then shell into the running instance with:

singularity shell instance://mysql

Login with root:

mysql -u root -p

Change the root password for localhost

ALTER USER 'root'@'localhost' IDENTIFIED BY '<root_password_here>';

Create root user with remote access (Optional)

CREATE USER 'root'@'%' IDENTIFIED BY '<root_password_here>'; GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;

Shutdown

Simply run:

singularity instance stop mysql

Normal Startup

To start normally after the first time setup has been done simply run

singularity instance start --bind <path_to_var_lib_mysql>:/var/lib/mysql/ --bind <path_to_var_run_mysqld>:/var/run/mysqld/ --bind <path_to_my.cnf>:/etc/mysql/my.cnf mysql.sif mysql
