Install Databag on Raspberry Pi Zero (1)

These instructions assume you have the following setup:

reverse proxy with an assigned hostname and certificate forwarding to your Raspberry Pi
micro usb to ethernet adapter
address reservation on your router
reasonably large micro sd card (~64 GB)

Step 1: setup the hardware

Download the DietPi OS and select the ARMv6 32-bit image: https://dietpi.com/downloads/images/DietPi_RPi-ARMv6-Bullseye.7z Extract the img file with 7-zip Write the img file to the sd card with Rufus Insert the sd card in the pi and turn it on

Step 2: install the OS

SSH into the pi with root:dietpi Watch it update and reboot Install the minimal image

Step 3: install databag dependencies

apt-get -y install curl apt-get -y install net-tools apt-get -y install jq apt-get -y install netcat apt-get -y install unzip apt-get -y install wget apt-get -y install git apt-get -y install vim apt-get -y install fail2ban apt-get -y install imagemagick-6.q16 apt-get -y install ffmpeg apt-get -y install build-essential apt-get -y install sqlite3 apt-get -y install openssh-client

Step 4: install golang

Download the armv6l version: https://go.dev/dl/go1.19.linux-armv6l.tar.gz Extract it to /usr/local tar -C /usr/local -xzf go1.19.linux-armv6l.tar.gz

Step 5: setup databag paths

mkdir -p /var/lib/databag mkdir -p /opt/databag/transform cp /app/databag/net/container/transform/* /opt/databag/transform/

Step 6: initialize the internal datbase

sqlite3 /var/lib/databag/databag.db "VACUUM;" sqlite3 /var/lib/databag/databag.db "CREATE TABLE IF NOT EXISTS 'configs' ('id' integer NOT NULL UNIQUE,'config_id' text NOT NULL,'str_value' text,'num_value' integer,'bool_value' numeric,'bin_value' blob,PRIMARY KEY ('id'));" sqlite3 /var/lib/databag/databag.db "CREATE UNIQUE INDEX IF NOT EXISTS 'idx_configs_config_id' ON 'configs'('config_id');" sqlite3 /var/lib/databag/databag.db "insert into configs (config_id, str_value) values ('asset_path', '/var/lib/databag/');" sqlite3 /var/lib/databag/databag.db "insert into configs (config_id, str_value) values ('script_path', '/opt/databag/transform/');"

Step 7: clone and build the server

mkdir /app cd /app git clone https://github.com/balzack/databag.git cd /app/databag/net/server /usr/local/go/bin/go build databag

Step 8: download the webapp

// because the react toolchain isn't available for the pi zero, the webapp is build in a github action Download webapp.zip from the most recent build: https://github.com/balzack/databag/actions/runs/2981276524 SCP webapp.zip into the pi Extract it into the web/build directory mkdir /app/databag/net/web/build unzip webapp.zip -d /app/databag/net/web/build/

Step 9: launch the server

cd /app/databag/net/server nohup /usr/local/go/bin/go run databag

Step 10: configure the server

Open your brower to the pi hostname Click the 'cog' in the upper right Set an admin password Select the 'cog' to bring up the settings modal - set your hostname - set the key to RSA 2048 - enable images - disable audio - disable video

Step 11: create accounts

Still in the admin dashboard Click the 'add-user' button Open the link in a new tab Set a username and password Setup your profile Connect with contacts on federated instances

Step 12: host for your friends and family

Back in the admin dashboard Click the 'add-user' and send the link to anyone you want to host
