Rebuild database after Docker clobbers it

1. Assuming docker is crashing, so nothing is using db
2. mkdir /opt/mysql
3. Copy database from /opt/Zoneminder/mysql /opt/mysql
4. Attempt to start database with innodb recovery options set to allow it to run (mariadb_conf.d/50-server.cfg)
5. mysqldump -u zmuser -pzmpass zm >> /tmp/dump.sql
6. Remove the innodb recovery options so we can run normal
7. /usr/bin/mysql_install_db --defaults-file=/etc/mysql/my.cnf (If you edited to point to /opt/mysql in config)
   1. mysql_install_db --user=mysql --datadir=/opt/mysql --basedir=/usr ----auth-root-authentication-method=socket
8. Start local database: /etc/init.d/mysql start
9. login to database:
   1. use mysql;
   2. create USER 'zmuser'@'localhost' IDENTIFIED BY 'zmpass';
   3. grant all privileges on zm.* to 'zmuser'@'localhost';
   4. flush privileges;
   5. create database zm;
10. sudo mysql -u root -S /var/run/mysqld/mysqld.sock zm < /tmp/dump.sql
11. stop database
12. copy database back into /opt/Zoneminder/mysql
13. chown back to correct usierid (will not match mysql)
14. Start docker container (sudo docker start Zoneminder)

Make damn sure that you lock down the docker version

apt-mark showhold
docker-ce
docker-ce-cli
docker-ce-rootless-extras
docker-scan-plugin

Docker run command

docker run -d --name="Zoneminder" --restart unless-stopped --net="bridge" --privileged="false" --shm-size="8G" -p 8443:443/tcp -p 8081:80/tcp -p 9000:9000/tcp -e TZ="America/Los_Angeles" -e PUID="99" -e PGID="100" -v "/opt/Zoneminder":"/config":rw -v "/opt/Zoneminder/data":"/var/cache/zoneminder":rw dlandon/zoneminder tail -f /dev/null

Settings for Blob Detection

TESTING ONLY - Mixed results -

Min/Max Pixel Threshold  40 empty
Filter Width/Height      5 5
Min/Max Alarmed Area     6 75
Min/Max filtered Ares    4 75
Min Max Blob Ara         3 empty
Min/Max Blobs            1 empty

TESTING MUCH BETTER
