1. steps to create a docker container from scratch: step 1: build.sh file: build a docker (after writing the docker file), tag it and push it step 2: run a docker

2. workflow in CMD for multiple GPUs (goal: create #gpus independent running consoles in the background (session interrupted even after closing the tab) from 1 source docker image)

step 1: 1) tmux new session 2) run docker 3) and then detach it (leave it alone all the time!) - this is your general debugging container - all GPUs are visible

step 2 (this might be in conflict with step 1, will raise error NVML not available since GPU will be allocated twice): 1) tmux new session 2) run docker_multiple gpus (i.e. docker run -d --gpus device=$i --name gpu_i xxx) 3) detach it. this creates #gpus containers that is used for running scripts

step 3: 1) tmux new session 2) attach docker for gpu_i created in step 2

step 4-x: repeat step 3 for the number of gpus.

4. find all available docker:

docker images

3. commit the current container to docker image (not inside docker but outside terminal):

docker commit --container_id --docker_image

4. tag the current docker image:

docker tag docker_name docker_tagged_name

5. push a docker image to server/hub:

docker push docker_tagged_name

6. check docker container id open a external terminal (not inside docker)

docker ps

7. attach to an existing docker

docker attach container_id
