sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io
sudo systemctl start docker
sudo systemctl enable docker
sudo systemctl status docker
sudo docker --version

6.添加可用的apt源

cat > /etc/docker/daemon.json << EOF
{"registry-mirrors": ["https://docker.registry.cyou","https://docker-cf.registry.cyou","https://dockercf.jsdelivr.fyi","https://docker.jsdelivr.fyi","https://dockertest.jsdelivr.fyi","https://mirror.aliyuncs.com","https://dockerproxy.com","https://mirror.baidubce.com","https://docker.m.daocloud.io","https://docker.nju.edu.cn","https://docker.mirrors.sjtug.sjtu.edu.cn","https://docker.mirrors.ustc.edu.cn","https://mirror.iscas.ac.cn","https://docker.rainbond.cc"],"insecure-registries": ["0.0.0.0/0"],"exec-opts": ["native.cgroupdriver=systemd"],"log-driver": "json-file","log-opts": {"max-size": "100m"},"storage-driver": "overlay2"
