1、下載并上傳docker離線安裝包

官方地址：安裝包下載

2、上傳到離線安裝的服務器解壓

tar -zxvf docker-28.1.1.tgz#拷貝解壓二進制文件到相關目錄
cp docker/* /usr/bin/

3、創建docker啟動文件

cat << EOF > /usr/lib/systemd/system/docker.service [Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target[Service]
Type=notify
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutStartSec=0
RestartSec=2
Restart=always
StartLimitBurst=3
StartLimitInterval=60s
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
TasksMax=infinity
Delegate=yes
KillMode=process
OOMScoreAdjust=-500[Install]
WantedBy=multi-user.targetEOF

4、創建Containerd啟停文件

cat << EOF > /usr/lib/systemd/system/containerd.service # Copyright The containerd Authors.

# you may not use this file except in compliance with the License.

Description=containerd container runtime
Documentation=https://containerd.io
After=network.target local-fs.target[Service]
ExecStartPre=-/sbin/modprobe overlay
ExecStart=/usr/bin/containerdType=notify
Delegate=yes
KillMode=process
Restart=always
RestartSec=5# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNPROC=infinity
LimitCORE=infinity# Comment TasksMax if your systemd version does not supports it.
# Only systemd 226 and above support this version.
TasksMax=infinity
OOMScoreAdjust=-999[Install]
WantedBy=multi-user.targetEOF

5、啟動Containerd

systemctl enable --now containerdsystemctl status containerd

6、啟動docker

systemctl enable --now dockersystemctl status docker

二、鏡像包處理

1、從有鏡像包的服務器導出鏡像

docker save -o oracle-12c.zip 21789d4d876f

2、上傳導出的鏡像到離線服務器上

docker load < oracle-12c.zip

有了鏡像后，就可以正常創建服務了。
