Building for ARMv7

[breakingflower]

I wanted to build for ARMv7 using your Dockerfile, straight from docker-compose.

Usefull system info:

pi@naspi:~/rpi4_server $ cat /proc/device-tree/model
Raspberry Pi 4 Model B Rev 1.1
pi@naspi:~/rpi4_server $ uname -a 
Linux naspi 5.4.51-v7l+ #1333 SMP Mon Aug 10 16:51:40 BST 2020 armv7l GNU/Linux
pi@naspi:~/rpi4_server $ lsb_release -a
No LSB modules are available.
Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 10 (buster)
Release:        10
Codename:       buster
pi@naspi:~/rpi4_server $ docker --version
Docker version 19.03.13, build 4484c46
pi@naspi:~/rpi4_server $ docker-compose --version
docker-compose version 1.27.4, build unknown

The docker-compose build is unknown due to it being installed with pip3 (only way to get up to date docker-compose version).

I use the following compose file, copied largely from this

  planka:
    image: fremmen/planka:armv7
    build: https://github.com/plankanban/planka.git
    command: >
      bash -c
        "for i in `seq 1 30`; do
          ./start.sh &&
          s=$$? && break || s=$$?;
          echo \"Tried $$i times. Waiting 5 seconds...\";
          sleep 5;
        done; (exit $$s)"
    restart: unless-stopped
    volumes:
      - ${CLOUD_ROOT}/planka/user-avatars:/app/public/user-avatars
      - ${CLOUD_ROOT}/planka/project-background-images:/app/public/project-background-images
      - ${CLOUD_ROOT}/planka/attachments:/app/public/attachments
    ports:
      - "${PLANKA_PORT}:1337"
    environment:
      - BASE_URL=XXXXXX
      - DATABASE_URL=postgresql://postgres@postgres/planka
      - SECRET_KEY=XXXXXXXX
    depends_on:
      - plankadb

Building the fremmen/planka:arm image is done using docker-compose build planka. The following errors occur:

The required dependencies for sharp show that there are no sharp prebuild libvips.

The following platforms have prebuilt libvips but not sharp:

    Linux ARMv6
    Linux ARMv7 (glibc >= 2.28)

Would be great to be able to build straight from GitHub for ARMv7!

Upon further inspection, it can be observed that the generated download link for the sharp binaries is incorrect

info sharp Downloading https://github.com/lovell/sharp-libvips/releases/download/v8.10.0/libvips-8.10.0-linuxmusl-armv7.tar.br

I'm not sure why the linux version is translated into linuxmusl instead of just linux. Maybe this error is not planka related but sharp-libvips. The file https://github.com/lovell/sharp-libvips/releases/download/v8.10.2-alpha2/libvips-8.10.2-linux-armv7.tar.br does exist.

After a full day of trying, I was able to compile libvips from the source. Sharp is successfully installed after that. Checking how Planks works with that and will commit this.
