Watchtower (for MySQL + Docker)

Watchtower

Watchtower is a Python application designed for monitoring multiple MySQL instances in Docker, specifically built for Prowl.

Usage

Server list file is a CSV file that contains the Prowl group name, the Prowl hostname as well as the MySQL port, assuming your server list file is named "serverlist" cat into it

cat serverlist.txt
group1,test1,3306
group1,test2,3306
group2,test3,3307
group2,test4,3307

Running it with a custom MySQL config file using Docker

The MySQL startup configuration in these Docker images is specified in the file /etc/my.cnf. If you want to customize this configuration for your own purposes, you can create your alternative configuration file in a directory on the host machine and then mount this file in the appropriate location inside the MySQL container, effectively replacing the standard configuration file

docker run --name some-mysql -v /my/custom:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag

Docker optimized MySQL install

All binaries are stripped, non-debug only, this is only expected to be relevant for a large majority of Prowl employees who run Docker based MySQL instances

   /usr/bin/my_print_defaults
   /usr/bin/mysql
   /usr/bin/mysql_config
   /usr/bin/mysql_install_db
   /usr/bin/mysql_tzinfo_to_sql
   /usr/bin/mysql_upgrade
   /usr/bin/mysqldump
   /usr/sbin/mysqld
    

Create a MySQL user account

GRANT REPLICATION CLIENT ON *.*  to {USER}@{MONITOR_SERVER_IP} IDENTIFIED BY '{PASSWORD}';

Run Watchtower

python watchtower.py serverlist.txt USER PASS
