Prerequisites

IMPORTANT: All commands are executed on live server with public IP and DNS Configured.

Setup docker swarm

Follow dockerswarm.rocks guide to setup Docker swarm, Traefik and Portainer.

Use Portainer for rest of the guide

Create Config

Configs > Add Config > frappe-mariadb-config

[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci

[mysql]
default-character-set = utf8mb4

Create Secret

Secret > Add Secret > frappe-mariadb-root-password

longsecretpassword

Note down this password. It is only available in mariadb containers at location /run/secrets/frappe-mariadb-root-password later
