h1. Setup erpnext14 dockerized 

the basic idea is taken from https://www.youtube.com/watch?v=8Q5B7DnxmLg

use of docker compose v2

h2. download pwd.yml (version erpnext:v14.44.0)

https://github.com/frappe/frappe_docker/blob/0333e62884b706d01d38804472f71b3f6a039ff6/pwd.yml

save in @/home/user/erpnext@ as @docker-compose.yml@

h2. migrate erpnext from different server

https://discuss.frappe.io/t/moving-to-docker/80457/4

<pre>

Moving a site.

    Take bench --site {site-name} backup --with-files on the running setup.

    Copy files from sites/{site-name}/private/backups to new server and optionally stop old server so users don’t create new data.

    In case of container setup copy files from server into container using docker cp or placing files in volume location.

    Enter any worker container and create site using bench new-site --no-mariadb-socket command. Name the site as per configured domain name. (Note down the db_name from site_config.json created)

    Enter mariadb container / use mysql client and execute drop database {db_name}; create database {db_name}. This will clean the site db that was created by new site. We do this so that we have a running site configured without any database resulting in Internal Server Error.

    In mysql shell execute, use {db_name}; source /path/to/database.sql. This will restore the database from backup on fresh db. We use source from mysql shell as it re-connects in case of disconnection or timeout during restoration of huge database. Simple alternate command will be mysql -uroot -p{root-password} -h{hostname} {db_name} < /path/to/database.sql

    Copy additional keys and encryption_key from backed up site_config.json. (Note, DO NOT change the db_name, db_password keys from newly created site, only copy other keys from backup site_config)

</pre>

and don't forget ..

bench --site erpnext migrate
