Docker build - base question

[NN-Binary]

Hello!

I'm trying to change a few things in .docker and build, no issues so far, but when I inspect file .docker/brave/Dockerfile for example, I see

ARG BASE_IMAGE=m1k1o/neko:base
FROM $BASE_IMAGE

How do I specify the BASE_IMAGE as the one from .docker? So it doesn't go online.

[m1k1o]

Hello, if that image is available locally it won't go online. So if you build local image with extactly that name, it will be used. e.g.: docker build -t m1k1o/neko:base .

You can use ./build base and ./build brave scripts, they do exactly what you want.

Thank you! Indeed yes, I didn't know that it will choose local first if it's already available.

[NN-Binary]

May I ask one last detail

command=/usr/bin/code --x11-display=%(ENV_DISPLAY)s --no-qt-privacy-ask %(ENV_VLC_MEDIA)s

What is the s in the end?

[m1k1o]

That is just supervisord syntax for passing variables:

%(ENV_X)s. where X is name of the environment variable.

[NN-Binary]

Awesome! Thank you so much for helping

I'm sorry, I don't want to abuse your time, I'm doing a lot of research but can't seem to figure out a weird bug. I'm actively trying to have Visual studio code (code) running, it does work, but constantly "restart" by itself

I can see VSCode literally started, then it closes and infinitely restarts. I could open a new issue but I have a feeling it's just my limited docker knowledges that cause this issue

You need to add --wait, it want to start in background. Here is working example, hope it hepls: https://github.com/m1k1o/neko-apps/blob/master/vscode/supervisord.conf
