# This is a Dockerfile for running and building Kubernetes dashboard
# It installs all deps in the container and adds the dashboard source
# This way it abstracts all required build tools away and lets the user run gulp tasks on the code with only docker installed

# golang is based on debian:jessie
FROM golang:1.5.3

# Install python, java and nodejs. go is already installed
# A small tweak, apt-get update is already run by the nodejs setup script, so there's no need to run it again
RUN curl -sL https://deb.nodesource.com/setup_5.x | bash - \
  && apt-get install -y --no-install-recommends \
	file \
	python \
	openjdk-7-jre \
  nodejs \
	&& rm -rf /var/lib/apt/lists/* \
	&& apt-get clean

# Download a statically linked docker client, so the container is able to build images on the host
RUN curl -sSL https://get.docker.com/builds/Linux/x86_64/docker-1.9.1 > /usr/bin/docker && \
    chmod +x /usr/bin/docker

# Current directory is always /dashboard
WORKDIR /dashboard

# Make an normal user, required for npm and bower, they are user programs and should not be called as root
RUN useradd normaluser -m -s /bin/bash && \
    chown -R normaluser /dashboard
# Our normal user should have access to /dashboard

# Switch user to normaluser
USER normaluser

# Copy over package.json bower.json and postinstall.sh.
# Why? Because of docker caching, npm install will only run again if one of these have changed
COPY package.json bower.json ./
COPY build/postinstall.sh build/

# Install all npm deps, bower deps and godep. This will take a while.
RUN npm install

# Copy over the rest of the source
COPY ./ ./

# Switch back to the root user when where going to communicate with docker
USER root
