Docker笔记

1.docker配置添加信任register

centos:

echo “OPTIONS=’–insecure-registry nexuscimgmt2.sgp.com:5000′” >> /etc/sysconfig/docker

ubuntu:

cat > /etc/docker/daemon.json << EOF
{
“insecure-registries”: [“nexuscimgmt2.sgp.com:5000″,”nexuscimgmt2.sgp.com:8087”]
}
EOF
systemctl restart docker
systemctl daemon-reload

2.常用命令

docker volume rm $(docker volume ls -qf dangling=true) || true
docker rm $(docker ps -q -f status=exited) || true
docker rmi $(docker images -f dangling=true -q) || true
docker rmi $(docker images | sed 1,2d | awk ‘{print $3}’) || true
docker image rmi $(docker images | sed 1d | awk ‘{print $3}’)
