Docker: Using apt-key with alpine image

Question

I\'m trying to use alpine (nodeJS) docker image, but I do get the error /bin/sh: apt-key: not found. What do I have to add?

FROM node:8.6-alpine
RUN         


        

Answer 1

Take a look on my sample Dockerfile.

FROM openjdk:8-alpine
RUN apk update \
    && apk fetch gnupg \
    && apk add gnupg \
    && gpg --list-keys

Answer 2

There’s no apt-key on Alpine, this is something from Debian.

Answer 3

You could use something as follows:

apk add --no-cache gnupg

gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 0C49F3730359A14518585931BC711F9BA15703C6
