    Overview of frequently used docker command

Running dockers

Run your docker with a specific executable and then shut down: sudo nvidia-docker run --rm nvidia/cuda nvidia-smi
Keep running your docker with bash access: sudo nvidia-docker run -ti --rm nvidia/cuda /bin/bash
Building your own docker file


Start by creating a Dockerfile inside a folder where you want to build your docker image
Go to NVIDIA docker hub: https://hub.docker.com/r/nvidia/cuda/ and select yourself a useful configuration
Open up your Dockerfile to the one side and a terminal on the other side
In the Dockerfile, start by


Adding the first line: FROM nvidia/cuda:8.0-cudnn5-devel where you replace the flavour after : with your choice
Make sure it ends with: CMD /bin/bash
Each command that works in your terminal (see below), can be added, with RUN before it
The cd-command is replaced by WORKDIR prefix


Start up a basis docker in your terminal using the command above, starting from an NVIDIA config
Experiment and fill in your Dockerfile
Once you are done, run in the folder with your file: sudo docker build . -t name:flavour

Making a folder accessible inside your docker


Create a shell script

#!/bin/bash

sudo nvidia-docker run -ti --rm \
-v /home/eavise-3frog/Desktop/test/data:/data \
name:flavor /bin/bash


Make sure that the -v option links an external location to an internal mount point where you can edit with sudo rights

Delete redundant docker content

Removing specific docker images

See all images: sudo docker images
Remove images: sudo docker rmi imageID

Look at the running containers

sudo docker ps -a
sudo docker rm containerID

Delete all containers that have been exited
sudo docker ps -a | grep Exit | cut -d ' ' -f 1 | xargs sudo docker rm
Add your user with sude rights for docker, so that you do not need sudo rights

sudo addgroup eavise-3frog docker
Visualize the output of your docker container --> X11 support

Make a bash script that containts the following lines of code
#!/bin/bash

xhost +SI:localuser:root

nvidia-docker run -ti --rm  \
-e DISPLAY=$DISPLAY \
-v /tmp/.X11-unix:/tmp/.X11-unix \
container:flavor /bin/bash

xhost -SI:localuser:root


And then all graphical output will not render issues.
