Vector Graphics vs Raster Graphics

Vector graphics is the use of polygons to represent images in computer graphics. Vector graphics are based on vectors, which lead through locations called control points or nodes. Each of these points has a definite position on the x- and y-axes of the work plane and determines the direction of the path; further, each path may be assigned various attributes, including such values as stroke color, shape, curve, thickness, and fill.

In computer graphics, a raster graphics or bitmap image is a dot matrix data structure, representing a generally rectangular grid of pixels

A raster is technically characterized by the width and height of the image in pixels and by the number of bits per pixel (or color depth, which determines the number of colors it can represent)

Removing Docker images and containers


1. List & Remove images
docker images -a
docker rmi image-name1 image-name2

2. List & removeDangaling Images
docker images -f dangling=true
docker rmi $(docker images -f dangling=true -q)

3. Remove all images
docker rmi $(docker images -a -q)

4. List & Remove images by pattern
docker ps -a |  grep "pattern"
docker images | grep "pattern" | awk '{print $1}' | xargs docker rm

5. List & Remove containers

docker ps -a
docker rm container1_id container2_id

docker container rm contianer-name


6. Remove container upon exit
docker run --rm image_name

7. List & Remove all exited containers
docker ps -a -f status=exited
docker rm $(docker ps -a -f status=exited -q)

8. Listing  & Removing using Multiple filters
docker ps -a -f status=exited -f status=created
docker rm $(docker ps -a -f status=exited -f status=created -q)

9. List and Remove all containers by pattern

docker ps -a |  grep "pattern”
docker ps -a | grep "pattern" | awk '{print $3}' | xargs docker rmi


10. Stop and remove all containers
docker ps -a

docker stop $(docker ps -a -q) 
docker rm $(docker ps -a -q)

docker stop container-name

11. List & Removing Volumes
docker volume ls
docker volume rm volume_name volume_name

12. List and remove all dangling volumes
docker volume ls -f dangling=true
docker volume rm $(docker volume ls -f dangling=true -q)

13. Remove Volume and its container
docker rm -v container_name
