h1. Setup erpnext15 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:v15.45.4)

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

save in @/opt/docker.compose/erpnext@ as @docker-compose.yml@

h2. usage of mounts instead of docker-volumes

didn't work for me .. mariadb yes, but erpnext no

h3. create directory structure

<pre><code class="shell">

mkdir -p /opt/docker.compose/erpnext/{c_db/var/lib/mysql,c_erp/home/frappe/frappe-bench/sites,c_erp/home/frappe/frappe-bench/logs,c_redis_cache/data,c_redis_queue/data,c_redis_socketio/data}

chmod -R g+w /opt/docker.compose/erpnext/c_*

chmod -R o+w /opt/docker.compose/erpnext/c_*

</code></pre>

fix permission issue within volume

<pre><code class="shell">

sudo docker exec --user root -it erpnext-backend-1 /bin/bash

chown -R frappe:frappe logs

chown -R frappe:frappe sites

</code></pre>

as a consequence stuck with volumes. Although they can be easily accessed from within the host.

h2. migrate erpnext from different server

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

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.

If existing site matches new site ... drop site first (https://frappeframework.com/docs/user/en/bench/reference/drop-site)

@bench drop-site erpnext --db-root-password admin@

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)

@bench new-site erpnext --no-mariadb-socket --verbose --db-root-password admin@

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.

<pre><code class="shell">

sudo docker exec -it erpnext-db-1 /bin/bash

mysql -p

  show database;

  drop database _76e6a5f706540e85;

  create database _76e6a5f706540e85;

</code></pre>

    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) The keys are important for the email-service, the hostname is important to 'wkhtmltopdf'

and don't forget ..

<pre><code class="shell">

bench --site erpnext migrate

</code></pre>

copy the tar-ed files into the corresponding directories

h2. erpnext as a service

https://stackoverflow.com/questions/43671482/how-to-run-docker-compose-up-d-at-system-start-up

<pre>

# /etc/systemd/system/docker-compose-erpnext.service 

[Unit]

Description=Docker Compose Application Service (erpnext)

Requires=docker.service

After=docker.service

[Service]

Type=oneshot

RemainAfterExit=yes

WorkingDirectory=/opt/docker.compose/erpnext

ExecStart=/usr/bin/docker compose up -d

ExecStop=/usr/bin/docker compose down

TimeoutStartSec=0

[Install]

WantedBy=multi-user.target

</pre>

<pre><code class="shell">

systemctl enable docker-compose-app

</code></pre>

h2. backup erpnext from outside a container

<pre><code class="shell">

sudo docker exec -t erpnext-backend-1 /usr/local/bin/bench --site all backup --with-files

</code></pre>

h1. upgrade erpnext v15

h2. shutdown erpnext

<pre><code class="shell">

sudo systemctl stop docker-compose-erpnext

</code></pre>

h2. modify compose-file

<pre><code class="shell">

sudo vim /opt/docker.compose/erpnext/docker-compose.yml

</code></pre>

replace all @frappe/erpnext:v15.20.6@ with the version desired (e.g. @v15.21.0@)

check whether mariadb-version or redis-version should be changed as well. (e.g. @mariadb 10.6@ / @redis-6.2@)

h2. restart erpnext manually

<pre><code class="shell">

cd /opt/docker.compose/erpnext/

sudo docker compose up

</code></pre>

h2. migrate erpnext installation (from within any erpnext-container)

<pre><code class="shell">

sudo docker ps

sudo docker exec -it b84444ac0cdb /bin/bash

bench --site erpnext migrate

</code></pre>

h2. stop manually started instance and restart service

<pre><code class="shell">

CTRL-C

sudo systemctl start docker-compose-erpnext

</code></pre>

h2. tidy up ..

<pre><code class="shell">

sudo docker system prune

</code></pre>
