Guide: Setting Up Nextcloud on Raspberry Pi with Advanced Features


Setting Up Nextcloud on Raspberry Pi with Advanced Features

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.
  1. 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.
  1. 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.
  1. Installing Docker Compose:
  • Follow the official Docker Compose installation guide to install Docker Compose on your Raspberry Pi OS.

    File Structure:

    /home/pi/nextcloud/

    ├── Dockerfile.app
    ├── Dockerfile.cron

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;

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

I’m trying to run nextcloud on a Raspberry Pi 5 8GB with Raspberry OS.

Now, I’m facing a noob issue here. After I run docker compose up -d from /home/emburaman/Docker/nextcloud/docker-compose.yml I get the below error:

Error response from daemon: error gathering device information while adding custom device "/dev/video10": no such file or directory
emburaman@emburaman:~/Docker/nextcloud $

Both nextcloud-cron-1 and nextcloud containers won’t start due to the error regarding /dev/video10.

The only way I can make it work is if I comment the /dev/video{n} from the docker-compose.yml file, which I believe is not ideal.

I’d appreciate any help and guidance you could provide… Thanks a lot.

@emburaman Can you install ‘sudo apt-get install v4l-utils’ and check if any hardware decoders are available? Use this command: ‘v4l2-ctl --list-devices’.

@Ankit_Das ,
Thanks for the quick response.

I did what you suggested and I got:

emburaman@emburaman:~/Docker/nextcloud $ v4l2-ctl --list-devices
pispbe (platform:1000880000.pisp_be):
        /dev/video20
        /dev/video21
        /dev/video22
        /dev/video23
        /dev/video24
        /dev/video25
        /dev/video26
        /dev/video27
        /dev/video28
        /dev/video29
        /dev/video30
        /dev/video31
        /dev/video32
        /dev/video33
        /dev/video34
        /dev/video35
        /dev/video36
        /dev/video37
        /dev/media0
        /dev/media1

rpivid (platform:rpivid):
        /dev/video19
        /dev/media2

Cannot open device /dev/video0, exiting.
emburaman@emburaman:~/Docker/nextcloud $

I don’t see video10, video11 or video12 on the list. So I changed the yml file to:

    devices:
      - /dev/video20:/dev/video20
      - /dev/video21:/dev/video21
      - /dev/video22:/dev/video22

And then Nextcloud container started with no error. But I honestly don’t know if my change will cause any unexpected/unwanted side effects. Will it?

Once again, thank you so much!!

In my case: ls /dev/video* output the available video devices are:

  • /dev/video19
  • /dev/video20
  • /dev/video21
  • /dev/video22
  • /dev/video23
  • /dev/video24
  • /dev/video25
  • /dev/video26
  • /dev/video27
  • /dev/video28
  • /dev/video29
  • /dev/video30
  • /dev/video31
  • /dev/video32
  • /dev/video33
  • /dev/video34
  • /dev/video35
  • /dev/video36
  • /dev/video37

None of the devices listed in your original configuration (/dev/video11, /dev/video12, and /dev/video10) exist on your system. Let’s update the docker-compose.yml file to use the existing devices. For demonstration, I’ll use /dev/video19, /dev/video20, and /dev/video21.

Here is the corrected docker-compose.yml file:

Validate and Restart Docker Compose:

  1. Validate Configuration:

sh

Copy code

docker-compose config
  1. Restart Services:

sh

Copy code

sudo docker-compose down
sudo docker-compose up -d

Verify Running Containers:

After starting the services, check that all containers are running correctly:

sh

Copy code

docker ps

This should list all running containers, and you should see nextcloud and nextcloud-cron running without errors.
