# Fix loaded image (if necessary)

Sometimes when I load an image and then list installed images it looks like this:

<none>                     <none>       3fea15423bc0   7 weeks ago     110MB

To fix it I added a tag to give the image a proper name:

sudo docker tag 3fea15423bc0 impacket:latest

# List containers

sudo docker ps

# Delete running docker container

sudo docker rm -f mycontainer

# Docker Compose install for Kali Linux

sudo apt install docker-compose
