# Dockerfile for testing 4d-agriculture
# Using a ROS image with Python 2.7.12 baked in:
FROM ros:kinetic

# Creates "docker" user, installs python-tk, sudo, then gives "docker" sudo rights (todo: test without sudo rights?)

	apt-get update && \
	apt-get install -y python-tk && \
	apt-get install -y sudo && \
	apt-get install -y unzip && \
	usermod -aG sudo docker

# Creates "docker" user's password
RUN echo 'docker:testpass' | chpasswd

# Makes ROS workspace and folder for 4d-agriculture-py2
RUN mkdir -p /home/docker/ros_workspace/src/4d-agriculture-py2

# Copies contents from this directory to the container's
COPY . /home/docker/ros_workspace/src/4d-agriculture-py2

RUN chown -R docker:docker /home/docker && \
	chmod 754 /home/docker/ros_workspace/src/4d-agriculture-py2/docker_run_4d-agriculture-py2.sh
