Docker Process

Docker Process (from https://www.youtube.com/watch?v=oGPjzCBZGzg)

1. List all docker containers (with their status)​

docker ps -a

2. List all docker images​

docker images

3. See hardware usage of running docker images​

docker stats

4. Remove a docker container​

docker rm -f <container_id>

Example: sudo docker rmi -f c22e695dfda2


5. Remove a docker image​

sudo docker rmi -f <image_id>

Example: sudo docker rmi -f ffc5b597096e

  • If an image is not removable due to some errors like

Error response from daemon: conflict: unable to delete image_id (cannot be forced) - image has dependent child images

Then use the image name with tag in the format image_name:tag

Always check what the error is saying and see if it is conveying something important.

Example: sudo docker rmi -f anaconda/conda:cpu


6. Enter into the shell of a docker container​

sudo docker exec -it <container_id> /bin/bash

Example: sudo docker exec -it ffc5b597096e /bin/bash


7. Save a docker image as zipped file​

docker save -o <tar_filename.tar> <image_name:tag>

Example docker save -o ollama.tar ollama/ollama:latest
