# DESCRIPTION: Create the atom editor in a container # AUTHOR: Jessie Frazelle <jess@linux.com> # COMMENTS: # This file describes how to build the atom editor # in a container with all dependencies installed. # Note: atom is not a node-webkit app, # found this out a little too late into this example # it uses electron(https://github.com/atom/electron) # Tested on Debian Jessie. # USAGE: # # Download atom Dockerfile # wget https://raw.githubusercontent.com/jessfraz/dockerfiles/master/atom/Dockerfile # # # Build atom image # docker build -t atom . # # docker run -v /tmp/.X11-unix:/tmp/.X11-unix \ # -e DISPLAY=unix$DISPLAY atom # # Base docker image FROM debian:buster LABEL maintainer "Jessie Frazelle <jess@linux.com>" # Install dependencies RUN apt-get update && apt-get install -y \ git \ gconf2 \ gconf-service \ gvfs-bin \ libasound2 \ libcap2 \ libgconf-2-4 \ libgnome-keyring-dev \ libgtk2.0-0 \ libnotify4 \ libnss3 \ libxkbfile1 \ libxss1 \ libxtst6 \ libx11-xcb-dev \ xdg-utils \ --no-install-recommends \ && rm -rf /var/lib/apt/lists/* ENV ATOM_VERSION 1.23.1 # download the source RUN buildDeps=' \ ca-certificates \ curl \ ' \ && set -x \ && apt-get update && apt-get install -y $buildDeps --no-install-recommends \ && rm -rf /var/lib/apt/lists/* \ && curl -sSL https://github.com/atom/atom/releases/download/v${ATOM_VERSION}/atom-amd64.deb -o /tmp/atom-amd64.deb \ && dpkg -i /tmp/atom-amd64.deb \ && rm -rf /tmp/*.deb \ && apt-get purge -y --auto-remove $buildDeps # Autorun atom ENTRYPOINT [ "atom", "--foreground" ] |
