loading image:

docker load < busybox.tar.gz

mount external address to /srv in docker storage:

--mount type=bind,source=$HOME,target=/mounted


sudo docker run  -it --mount type=bind,source=/home/usr/Desktop/app,target=/srv  mozilla

run multiple terminal with same container

docker exec -it <container> bash

run with gui support

xhost local:root

sudo docker run  -it -e DISPLAY=$DISPLAY  -v /tmp/.X11-unix:/tmp/.X11-unix:rw --mount type=bind,source=/home/usr/Desktop/app,target=/srv  mozilla

resize shared memory

--shm-size 8G

make docker image from docker file wuth custom image name

mkdir dockerdir
nano dockerdir/dockerfile
write these into file and save changes

FROM labelimage:latest as base

run this command

docker build -t image_name dockerdir/


# Run Docker commands without sudo

##### 1. Add the `docker` group if it doesn't already exist

```console
$ sudo groupadd docker
2. Add the connected user $USER to the docker group

Optionally change the username to match your preferred user.

$ sudo gpasswd -a $USER docker
3. Restart the docker daemon
$ sudo service docker restart

If you are on Ubuntu 14.04-15.10, use docker.io instead:

$ sudo service docker.io restart
4. save changes to a new image
$ sudo docker commit [container_id] [new_image_name]
5. save docker image
$ sudo docker save myimage:latest | gzip > myimage_latest.tar.gz
6. run your own new image
$ sudo nvidia-docker run -it myimage:latest

Import/Export container

Import a container as an image from file:

cat my_container.tar.gz | docker import - my_image:my_tag

Export an existing container:

docker export my_container | gzip > my_container.tar.gz

Difference between loading a saved image and importing an exported container as an image

Loading an image using the load command creates a new image including its history. Importing a container as an image using the import command creates a new image excluding the history which results in a smaller image size compared to loading an image.

Cleaning Docker Disk Space Usage

docker rm $(docker ps -a -q)

how to set special IP to our docker container:

First creat a network:
docker network create --subnet=192.168.1.1/16 mynet

Then run the container:
docker run --net mynet123 --ip 192.168.1.2 (***you can put 3 or 4 or ... instead of 2) -it docker_image_name

Run GUI app in linux docker container on windows host

1-install vcxsrv

open up windows PowerShell and use these commands:

set-variable -name DISPLAY -value 172.16.2.155:0.0

docker run -ti --rm -e DISPLAY=$DISPLAY nvidia/cuda:10.2-devel-ubuntu18.04
