Install yt-dlp in node:16.3.0-alpine base image

Question

This is my Dockerimage:

FROM node:16.3.0-alpine

WORKDIR /home/node/app

RUN apk update
RUN apk upgrade
RUN apk add --no-cache ffmpeg
RUN apk add --no-cache python3
RUN apk add --no-cache yt-dlp

When I try to build it fails at the yt-dlp step:

fetch https://dl-cdn.alpinelinux.org/alpine/v3.13/main/x86_64/APKINDEX.tar.gz
fetch https://dl-cdn.alpinelinux.org/alpine/v3.13/community/x86_64/APKINDEX.tar.gz
ERROR: unable to select packages:
  yt-dlp (no such package):
    required by: world[yt-dlp]
The command '/bin/sh -c apk add --no-cache yt-dlp' returned a non-zero code: 1

I don't understand why it can't find the package since it clearly exist in the community repo, which is enabled by default in the alpine image I'm using.

PD: I need the node base image to be version 16 because the app I'm trying to run (wiki.js in its last stable release) runs in node 16

By using the latest Node 16 version 16.20 you can successfully use yt-dlp.

Here is a working Dockerfile:

FROM node:16-alpine
RUN apk update && apk add --no-cache yt-dlp
