Start gui capabilities for docker containers (host os terminal):
```
xhost +local:docker &> /dev/null
```
Build docker image:
```
docker build -t <image_name> .
```
- If you want to push to docker hub use this format: (repo_name is like the image_name)
```
docker build -t <dockerhub_username>/<repo_name>:<tag_name> .
```

Create a container from an image:

docker run -it --name <container_name> <image_name>

If you want gui support and you have a Nvidia graphics card use these commands instead

DOCKER_COMMON_ARGS="--gpus all --env=NVIDIA_VISIBLE_DEVICES=all --env=NVIDIA_DRIVER_CAPABILITIES=all --env=DISPLAY --env=QT_X11_NO_MITSHM=1 -v /tmp/.X11-unix:/tmp/.X11-unix:rw"

for intel integrated graphics use the following:

DOCKER_COMMON_ARGS="--env="DISPLAY" --env="QT_X11_NO_MITSHM=1" -v "/tmp/.X11-unix:/tmp/.X11-unix:rw"

Run the following to create the container:

docker run -it --net=host --privileged $DOCKER_COMMON_ARGS --name <name_of_container> <image_name>

If you want to pass a folder into the container add the following to the docker run command after the --net=host: (paths need to be absolute paths)
```
-v <path_to_folder_on_host>:<path_to_folder_in_container>
```

Open an additional terminal in the container:
```
docker exec -it <container_name> bash
```
Start container:
```
docker start <container_name>
```
Stop container:
```
docker stop <container_name>
```
See running containers:
```
docker ps
```
See all containers on computer:
```
docker container ls -a 
```
See all images on computer:
```
docker image ls -a
```

Delete container:

docker rm <container_name or container_ID>

Delete Image:
```
docker rmi <image_name or image_ID>
```
Push image to docker hub:(make sure you made a repo on docker hub, that you named the image corretly and you signed into docker on your computer)
```
docker push <dockerhub_username>/<repo_name>:<tag_name>
```
