Lista lokalnych obrazów
Warto czasem zobaczyć jakie mamy obrazy na dysku:
$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE dpz/wildfly-blueocr latest 22af6d6fe20c 41 hours ago 4.791 GB dpz/opencv latest 7124e8b011a8 41 hours ago 4.765 GB dpz/wildfly latest 00f0de2d3fdc 41 hours ago 1.397 GB dpz/system latest f1ef0b164424 41 hours ago 1.098 GB centos 7 778a53015523 4 weeks ago 196.7 MB trigsoft/wildfly latest a251fdfa8320 10 weeks ago 635.4 MB
Usunięcie obrazów i kontenerów
Pracując z Dockerem możesz natknąć się na problem z dużą liczbą obrazów i kontenerów. Aby je wszystkie usunąć jedną komendą wystarczy:
# Delete all containers docker rm $(docker ps -a -q) # Delete all images docker rmi $(docker images -q)
Jeśli chcesz usunąć nieoznaczone obrazy wystarczy:
#!/bin/bash # Delete untagged images (dangling) docker rmi -f $(docker images -q --filter "dangling=true")
