I need to install ffmeg on debian jessie via Dockerfile.
Debian recommends to use backports. But how do I do this in my Dockerfile?
Add
deb http://httpredir.debian.org/debian jessie-backports main non-free
deb-src http://httpredir.debian.org/debian jessie-backports main non-free
to
/etc/apt/sources.list
This is how my Dockerfile looks like:
FROM node:4.8-slim
COPY . /
## How to add backports to list ???
RUN apt-get update && apt-get install ffmpeg && ffmpeg -i
RUN (cd programs/server && npm install --silent)
CMD ["node", "main.js"]
You can do it by adding below
RUN printf "deb http://httpredir.debian.org/debian jessie-backports main non-free\ndeb-src http://httpredir.debian.org/debian jessie-backports main non-free" > /etc/apt/sources.list.d/backports.list
