Issues with `init.sh`: Yarn missing + incorrect Redis URLs

[3aluw]

The current init.sh script has two problems that prevent a smooth setup:

1. Yarn is not installed

   • The script doesn’t install Yarn, which is required for Frappe/ERPNext builds.
   • Running bench build fails unless Yarn is installed manually.

2. Redis URLs are incorrect

   • The script sets Redis hosts using bench set-redis-* but appends the port directly in the URL (e.g., redis-cache:6379).
   • This results in connection issues, since bench set-redis-cache-host expects just the hostname (e.g., redis-cache), not host:port.

Current init.sh (for reference):

#!bin/bash

set -e

if [[ -f "/workspaces/frappe_codespace/frappe-bench/apps/frappe" ]]
then
    echo "Bench already exists, skipping init"
    exit 0
fi

rm -rf /workspaces/frappe_codespace/.git

source /home/frappe/.nvm/nvm.sh
nvm alias default 18
nvm use 18

echo "nvm use 18" >> ~/.bashrc
cd /workspace

bench init \
--ignore-exist \
--skip-redis-config-generation \
frappe-bench

cd frappe-bench

# Use containers instead of localhost
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

# Remove redis from Procfile
sed -i '/redis/d' ./Procfile

bench new-site dev.localhost \
--mariadb-root-password 123 \
--admin-password admin \
--no-mariadb-socket

bench --site dev.localhost set-config developer_mode 1
bench --site dev.localhost clear-cache
bench use dev.localhost

Suggested Fix:

• Install Yarn in the script (e.g., npm install -g yarn).
• Update Redis host commands to remove :6379 and only set hostnames.

Example:

npm install -g yarn

bench set-redis-cache-host redis-cache
bench set-redis-queue-host redis-queue
bench set-redis-socketio-host redis-socketio
