Status: Testing

• implementation
• testing

Reference: #3078

Commit list/description:

• DietPi-Software | Docker-Compose: reserve Software ID 187, get ready for further implementation.
• DietPi-Software | Docker-Compose: Add dependency for Docker and Python (pip)
• DietPi-Software | Docker-Compose: add install and removal process
• DietPi-Software | Python (pip): enable pipweels as additional pip repository for ARMv6 and ARMv7
• DietPi-Software | Docker-Compose: removed dependency libffi-dev and libssl-dev for aarch64/arm64. It is not required for building docker-compose
• DietPi-Software | Python (pip): move pipweels installation on top, to be setup first
• DietPi-Software | Docker-Compose: change software ID from 187 to 134

@MichaIng
should we make Docker Compose depending on Docker? Means, to install Docker along with Compose? I mean it doesn't make much sense without 🤣

[MichaIng]

I would say so, similar to how Portainer does.

@MichaIng
for the time being, I added all dependency for G_HW_ARCH 3 aarch64/arm64. On my test with RPi4 64bit, not all of them are needed. Unfortunately I don't have other boards to verify with other devices. Still I'm lacking how to simulate other boards on a VM 🤣

As well I did a first attempt to get pipweels activated for ARMv6 and ARMv7

Unfortunately I don't have other boards to verify with other devices.

I'll test it on other ARMv8 boards, however, RPi4 64-bit should behave the same as it is the same Debian APT repository.

[Joulinar]

I tested it on RPi4 64bit. There make and gcc are enough. Not sure about NonRPi boards

Still I'm lacking how to simulate other boards on a VM

QEMU is good at that. It has quite a few ARM and ARM64 emulated boards. DietPi doesn't have any images for any of them (except for the Raspberry Pis), though it does support the OrangePi PC, which is supported.

I was trying QEMU in past but never succeeded to get it running on my W10 box

during the last couple of days, I did some test installation and for me it was working fine. Would be good to have a 2nd pair of eyes checking. Especially on nonRPi boards.

Works very well on x86_64, used it to run the Pi-hole Docker container to do some testing there 👍. A quite simple install anyway, thanks to pip. Let me do some minor code changes, otherwise ready to be merged.

🤔 well piwheels config file is created for ARMv6 and ARMv7 only 😉
Or do you mean docker-compose?

[MichaIng]

Works great on VM and ARMv7. I'll merge.

[Joulinar]

ok I verified it once more on my RPi3B+ and first I was irritated by the output. Was not expecting the word-wrap to see 😄

but it is working well 👍

Indeed that looks strange. Also the notification function that aims to replace the execution animation doesn't recognise manual "\n" linebreaks, so the first line is not overprinted as expected.

I just fixed that within G_EXEC: 13a0edf
When the passed command contains any escape sequence (like \n newline), that sequence is part of the executed command, so should be shown in the output like that and not expanded through G_DIETPI-NOTIFY to an actual newline. That is quite easy by escaping all backslash characters with a second backslash.

Only left glitch: In the error prompt, the command will still be shown with an actual newline, as whiptail does not support escaping them at all. Like in console echo -e 'line1\\nline2' can be used to print "\n" literally, but in whiptail this leads to a backslash followed by an actual newline... But I think it's rare and unimportant enough to be ignored 😄.

[Joulinar]

way better now. well done 😃
