Getting Started

Prerequisites

Docker
docker-compose
user added to docker group

Bootstrap Containers for development

Clone and change to frappe_docker directory

git clone https://github.com/frappe/frappe_docker.git
cd frappe_docker

Manually start containers

In case VS Code is not used follow these steps.

docker-compose -f .devcontainer/docker-compose.yml up -d

Enter the bench container at location /workspace/development

docker exec -e "TERM=xterm-256color" -w /workspace/development -it devcontainer_frappe_1 bash

Use VS Code Remote Containers extension

Follow these in case VS Code is used. Do not start containers manually.

Install Remote Development Pack / Remote Containers extension.
Install VS Code Python extension.
Open frappe_docker in VS Code.
From Command Palette (Ctrl + Shift + P) Execute Remote Containers : Reopen in Container.

Setup Docker specific bench environment

Notes:

development directory is ignored by git. It is mounted and available in container. Create all your benches inside this directory.
Execute these commands from container.
nvm with node v12 and v10 is installed. Check with nvm ls. Node v12 is default.

Setup first bench

bench init --skip-redis-config-generation --frappe-branch version-12 frappe-bench
cd frappe-bench

Set hosts

bench set-mariadb-host mariadb
bench set-redis-cache-host redis-cache:6379
bench set-redis-queue-host redis-queue:6379
bench set-redis-socketio-host redis-socketio:6379

honcho/Procfile starts processes required for development.
By default Procfile has 3 redis processes that it starts. Comment (#) or remove these lines and then run bench start.
Another option is to run following command :

honcho start \
    web \
    socketio \
    watch \
    schedule \
    worker_short \
    worker_long \
    worker_default

Notes:

bench new-site command creates a user in mariadb with container IP as host
After rebuilding container there is a chance that new bench container will not be able to access mariadb
'db_name'@'%' needs to be set in mariadb and permission to the site database be given to the user
Replace db_name and db_password from site's site_config.json
MariaDB root password is 123

Enter mariadb shell

mysql -uroot -p123 -hmariadb

Execute following queries

UPDATE mysql.user SET Host = '%' where User = 'db_name'; FLUSH PRIVILEGES;
SET PASSWORD FOR 'db_name'@'%' = PASSWORD('db_password'); FLUSH PRIVILEGES;
GRANT ALL PRIVILEGES ON `db_name`.* TO 'db_name'@'%'; FLUSH PRIVILEGES;

Visual Studio Code Python Debugging

Install VS Code Python Extension once in remote container
Reload VS Code
Do not start web process with honcho

honcho start \
    socketio \
    watch \
    schedule \
    worker_short \
    worker_long \
    worker_default

On debugger tab, Connect debugger. This will start the web process with debugger connected
