Setting Up Nextcloud on Raspberry Pi with Advanced Features

Prerequisites:

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.

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.

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.

Installing Docker Compose:

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

File Structure:

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:

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

worker_processes auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  10024;

                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;

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

Step 9: Compare with your config.php file add/remove as per your requirement
