source: NextCloud Help

Prerequisites:

1. Raspberry Pi Hardware:

• Raspberry Pi board (e.g., Raspberry Pi 4 Model B).
• MicroSD card (preferably 16GB or larger) for Raspberry Pi OS installation.
• Power supply compatible with your Raspberry Pi model.

2. Raspberry Pi OS Installation:

• Download the latest Raspberry Pi OS Lite or Raspberry Pi OS with a desktop from the official Raspberry Pi website.
• Flash the Raspberry Pi OS image onto the microSD card using a tool like Raspberry Pi Imager or balenaEtcher.
• Insert the microSD card into your Raspberry Pi board and power it on.
• Follow the on-screen instructions to complete the initial setup of Raspberry Pi OS, including setting up Wi-Fi, expanding the filesystem, and configuring localization settings if necessary.
• Ensure your Raspberry Pi is connected to the internet via Ethernet or Wi-Fi.

3. Installing Docker:

• Follow the official Docker installation guide for Raspberry Pi to install Docker on your Raspberry Pi OS. This typically involves adding Docker’s official repository to your package manager and installing Docker packages using apt.

4. Installing Docker Compose:

• Follow the official Docker Compose installation guide to install Docker Compose on your Raspberry Pi OS.

Quick Setup Instructions

Follow these steps for a quick setup of your Nextcloud environment. This script will automatically generate necessary certificates, configure Nginx, create essential environment files, and set up required directories.

1. Create the Docker Volume

• Run the following command to create the Docker volume named nextcloud_sslcerts:

sudo docker volume create nextcloud_sslcerts

This command creates a Docker volume where your SSL/TLS certificates will be stored.

2. Save the Setup Script

• Save the following script as setup-nextcloud.sh:

#!/bin/bash

# Determine the home directory
HOME_DIR="$HOME"

# Define the Docker volume name (assumes 'nextcloud_sslcerts' volume exists)
VOLUME_NAME="nextcloud_sslcerts"

# Get the Docker volume path
DOCKER_VOLUME_PATH=$(docker volume inspect "$VOLUME_NAME" --format '{{ .Mountpoint }}')

# Check if the Docker volume path was obtained successfully
if [ -z "$DOCKER_VOLUME_PATH" ]; then
    echo "Error: Docker volume '$VOLUME_NAME' not found. Please create the volume before running this script."
    exit 1
fi

# Define directories and files
CERTS_DIR="$HOME_DIR/nextcloud/certs"
NGINX_CONF="$HOME_DIR/nextcloud/nginx.conf"
DOCKERFILE_APP="$HOME_DIR/nextcloud/Dockerfile.app"
DB_ENV="$HOME_DIR/nextcloud/db.env"
ENV_FILE="$HOME_DIR/nextcloud/.env"
DOCKER_VOLUME_CERTS_DIR="$DOCKER_VOLUME_PATH"

# Create directories if they do not exist
mkdir -p "$CERTS_DIR"
mkdir -p "$HOME_DIR/nextcloud"
mkdir -p "$DOCKER_VOLUME_CERTS_DIR"

# Generate SSL/TLS Certificates and Diffie-Hellman Parameters
cd "$CERTS_DIR" || exit

# Generate RSA private key if it doesn't already exist
if [ ! -f "mycloud.example.com.key" ]; then
    openssl genrsa -out mycloud.example.com.key 2048
    echo "Generated RSA private key: mycloud.example.com.key"
else
    echo "RSA private key already exists: mycloud.example.com.key"
fi

# Generate self-signed CA certificate if it doesn't already exist
if [ ! -f "myCA.pem" ]; then
    openssl req -x509 -new -nodes -key mycloud.example.com.key -sha256 -days 365 -out myCA.pem -subj "/C=US/ST=State/L=City/O=Organization/OU=Unit/CN=MyCA"

    echo "Generated Certificate Signing Request: mycloud.example.com.csr"
else
    echo "Certificate Signing Request already exists: mycloud.example.com.csr"
fi

# Sign the certificate with the CA certificate if it doesn't already exist
if [ ! -f "mycloud.example.com.crt" ]; then
    openssl x509 -req -in mycloud.example.com.csr -CA myCA.pem -CAkey mycloud.example.com.key -CAcreateserial -out mycloud.example.com.crt -days 365 -sha256
    echo "Signed certificate with CA: mycloud.example.com.crt"
else
    echo "Signed certificate already exists: mycloud.example.com.crt"
fi

# Generate Diffie-Hellman parameters if it doesn't already exist
if [ ! -f "dhparam.pem" ]; then
    openssl dhparam -out dhparam.pem 2048
    echo "Generated Diffie-Hellman parameters: dhparam.pem"
else
    echo "Diffie-Hellman parameters already exist: dhparam.pem"

3. Make the Script Executable

• Run the following command to make the setup-nextcloud.sh script executable:

chmod +x /root/nextcloud/setup-nextcloud.sh

4. Run the Script

• Execute the script to complete the setup:

/root/nextcloud/setup-nextcloud.sh

This script will automatically create the required directories, generate SSL certificates, configure Nginx, and prepare the environment for running Nextcloud.

Check the .env and db.env file and update NEXTCLOUD_EXTDATA variable with your external storage path if needed

5. Create a docker-compose.yml File

• To simplify the management of your Nextcloud environment, create a docker-compose.yml file in the /root/nextcloud directory:

Manual Setup Steps [Hidden]

Step 1: Docker Compose Configuration

First, create a docker-compose.yml file with the following configuration:

Here /mnt/ad/nextcloud is the folder path of the external HDD in my Raspberry Pi. You can change this path.

version: '3'

services:
  db:
    image: postgres:alpine
    restart: always
    volumes:
      - db:/var/lib/postgresql/data:Z
    env_file:
      - db.env
    environment:
      - PUID=109
      - PGID=65534
    networks:
      - proxy-tier


  cache:
    image: redis:6.2-alpine
    restart: always
    ports:
      - '6379:6379'
    command: redis-server --save 20 1
    volumes: 
      - cache:/data
    networks:
      - proxy-tier


  app:
    #image: nextcloud:fpm-alpine
    build:
      context: .
      dockerfile: Dockerfile.app

    environment:
      - PHP_MEMORY_LIMIT=2048M
    networks:
      - proxy-tier

  imaginary:
    image: ghcr.io/italypaleale/imaginary:master
    container_name: imaginary
    restart: always
    ports:
      - '9000:9000'
    command: -enable-url-source

  nginx-proxy:
    image: nginx:alpine
    container_name: nginx-proxy
    ports:
      - "8443:443"
    volumes:

Step 2: Dockerfile Configuration [Dockerfile.app]

Create a Dockerfile.app with the following content:

# Use the official Nextcloud image as a base image
FROM nextcloud:stable-fpm-alpine

# Install build essentials
RUN apk update && \
    apk add --no-cache build-base

# Install imagemagick-common and ffmpeg
RUN apk add --no-cache ffmpeg \
    && apk add --no-cache nodejs npm \
    && apk add --no-cache util-linux \
    && apk add --no-cache git g++ cmake ghostscript libx11-dev sudo nano

# Set the NODE_PATH environment variable to point to the Node.js binary
ENV NODE_PATH /usr/bin/node
ENV NICE_CMD /usr/bin/nice

RUN git clone https://github.com/davisking/dlib.git \
 && cd dlib/dlib \
 && mkdir build \
 && cd build \
 && cmake -DBUILD_SHARED_LIBS=ON .. \
 && make \
 && make install

RUN git clone https://github.com/goodspb/pdlib.git /usr/src/php/ext/pdlib

RUN docker-php-ext-install pdlib

# Install BZip2 library and development files
RUN apk add --no-cache bzip2-dev

# Install php-bz2
RUN docker-php-ext-install bz2

# Install smbclient
RUN apk add --no-cache samba-client

# Clean up unnecessary build dependencies
RUN apk del build-base cmake git

Step 3: Dockerfile Configuration [Dockerfile.cron]

Create a Dockerfile.cron with the following content:

# Use the official Nextcloud image as a base image
FROM nextcloud:stable-fpm-alpine

# Install build essentials
RUN apk update && \
    apk add --no-cache build-base

# Install imagemagick-common and ffmpeg
RUN apk add --no-cache ffmpeg \
    && apk add --no-cache nodejs npm \
    && apk add --no-cache util-linux \
    && apk add --no-cache git g++ cmake ghostscript libx11-dev sudo nano

# Set the NODE_PATH environment variable to point to the Node.js binary
ENV NODE_PATH /usr/bin/node
ENV NICE_CMD /usr/bin/nice

RUN git clone https://github.com/davisking/dlib.git \
 && cd dlib/dlib \
 && mkdir build \
 && cd build \
 && cmake -DBUILD_SHARED_LIBS=ON .. \
 && make \
 && make install

RUN git clone https://github.com/goodspb/pdlib.git /usr/src/php/ext/pdlib

RUN docker-php-ext-install pdlib

# Install BZip2 library and development files
RUN apk add --no-cache bzip2-dev

# Install php-bz2
RUN docker-php-ext-install bz2

# Install smbclient
RUN apk add --no-cache samba-client

# Clean up unnecessary build dependencies
RUN apk del build-base cmake git

Step 4: Generating SSL/TLS Certificates and Diffie-Hellman Parameters

Execute the following commands in your terminal to generate SSL/TLS certificates and Diffie-Hellman parameters:

You don’t have to write anything for the certificate generation, just press the enter key

cd ~
sudo mkdir nextcloud/certs
cd nextcloud/certs
sudo su

openssl genrsa -out mycloud.example.com.key 2048
openssl req -x509 -new -nodes -key mycloud.example.com.key -sha256 -days 365 -out myCA.pem

openssl req -new -key mycloud.example.com.key -out mycloud.example.com.csr
openssl x509 -req -in mycloud.example.com.csr -CA myCA.pem -CAkey mycloud.example.com.key -CAcreateserial -out mycloud.example.com.crt -days 365 -sha256

openssl dhparam -out dhparam.pem 2048

Step 5: Create a db.env file at /home/pi/nextcloud

POSTGRES_PASSWORD=somesecurepassword
POSTGRES_DB=nextcloud
POSTGRES_USER=nextcloud

Step 6: Create nginx.conf file at /home/pi/nextcloud

Step 7: Copy/Create files at

/var/lib/docker/volumes/nextcloud_sslcerts/_data

• Create 3 files key.pem, cert.pem and dhparam.pem at 

  /var/lib/docker/volumes/nextcloud_sslcerts/_data

• Copy

  /home/ankit/nextcloud/certs/dhparam.pem → dhparam.pem

• Copy

  /home/ankit/nextcloud/certs/mycloud.example.com.key → key.pem

• Copy

  /home/ankit/nextcloud/certs/myCA.pem → cert.pem

Step 8: This is the second last step, trust me.

Please be patient as this task will consume some time. Take a break and enjoy a cup of coffee while waiting.
You can access nextcloud at https://raspberrypi.local:8443

sudo docker-compose up -d
