Debian Dockerfile refactoring and improvements

[gaby]

• Migrate from node:14-bullseye to node:14-bullseye-slim image.
• Remove unnecessary package installation.
• Apprise publishes a Python wheel for Debian distributions, which allows for removing the installation of development tools (g++, make) and python libraries via apt-get.
• Decreases by 51% the uncompressed Docker image size from 1.31 GB to 639 MB.

Testing:

• Built image locally using Ubuntu Focal 20.04 LTS
• Started the Docker container and added 3 monitors (HTTPS, PING, DNS).
• I have no way of testing this for ARM.

Update: I have a Raspberry PI 4 8GB running Raspberry Pi OS (32-bit), I'm going to try build/test the image there too.

Thanks, but have to keep the original order, because I believe that this change breaks the cache layer of node-sqlite3 if you put COPY at top. Building node-sqlite3 is painful slow.

1. WORKDIR /app
2. node-sqlite3
3. apprise
4. COPY . .

Thanks for your info, I always thought PI 4 is using arm64

Just commited changes, to fix the caching issue with node-sqlite3.

I just tried building for ARM64 and it fails. The reason being that when the npm install runs, the MapBox team is blocking access to the binaries so it tries to build the whole thing from scratch. See here: TryGhost/node-sqlite3#1389

There's a merge request to fix this here: TryGhost/node-sqlite3#1362

I will work tomorrow on creating a multi-stage build to separate the MapBox into a separate stage. Do not merge this yet. :-)

#16 262.2     error: command 'arm-linux-gnueabihf-gcc' failed: No such file or directory
#16 262.2     ----------------------------------------
#16 262.2     ERROR: Failed building wheel for cffi
#16 262.2     Running setup.py clean for cffi

apprise is failed too in my side. I believe those python package is needed.

Sorry about that, but I don't want the docker image to become unstable, and spend time to test it again. I only accept the change of the first line node:14-bullseye-slim. I won't accept other changes.

Please rebase or re-create an pull request for that.

@louislam Let me know if it looks good now.

Nice, build successfully and smaller size.

@gaby: Can you take a look at #122?

@gaby: Can you take a look at #122?

I did, but from my understanding uptime-kuma is moving away from Alpine because of all the DNS issues.
