手动安装

wget https://download.docker.com/linux/static/stable/x86_64/docker-24.0.0.tgz
tar -zxvf docker-24.0.0.tgz
cp docker/* /usr/bin/
vim /etc/systemd/system/docker.service

    Wants=network-online.target

    [Service]
    Type=notify
    # the default is not to use systemd for cgroups because the delegate issues still
    # exists and systemd currently does not support the cgroup feature set required
    # for containers run by docker
    ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock --selinux-enabled=false --default-ulimit nofile=65536:65536
    ExecReload=/bin/kill -s HUP $MAINPID
    # Having non-zero Limit*s causes performance problems due to accounting overhead
    # in the kernel. We recommend using cgroups to do container-local accounting.
    LimitNOFILE=infinity
    LimitNPROC=infinity
    LimitCORE=infinity
    # Uncomment TasksMax if your systemd version supports it.
    # Only systemd 226 and above support this version.
    #TasksMax=infinity
    TimeoutStartSec=0
    # set delegate yes so that systemd does not reset the cgroups of docker containers
    Delegate=yes
    # kill only the docker process, not all processes in the cgroup
    KillMode=process
    # restart the docker process if it exits prematurely
