Remove dangling images
docker image prune
sh
Or remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all dangling build cache
docker system prune
sh

docker rmi [image name]
docker rm [container name]

Using Buildx to build image for ARM#
docker buildx build \
--tag your-username/multiarch-example:latest \
--platform linux/amd64,linux/arm/v7,linux/arm64 .
Display command output with Buildx#
Just add a --progress=plain
flag.
Add IPv6#
Disclaimer: may be inaccurate
In /etc/docker/daemon.json
:
{
"ipv6": true,
"fixed-cidr-v6": "2001:3200:1::/64"
}
json
And run:
sudo systemctl reload docker
sh
This reload is graceful so that you don't need to stop containers.
Then in docker-compose.yml
:
services:
app:
# ...
networks:
- app_net
networks:
app_net:
enable_ipv6: true
driver: bridge
ipam:
driver: default
config:
- subnet: 2001:db8:1::/64
gateway: 2001:db8:1::1
