linux无外网情况下docker环境搭建和导入导出镜像

针对无网络情况下的docker环境搭建

下载文件
https://download.docker.com/linux/static/stable/

解压

tar xzvf docker-19.03.5.tgz 

拷贝

sudo cp docker/* /usr/bin/

配置service文件

vi /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
LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
 
[Install]
WantedBy=multi-user.target

启动dockerd服务进程

systemctl daemon-reload
systemctl start docker.service

至此docker部署完成

从外部导出想用的image文件

docker images

导出 docker save [IMAGE ID] > file.tar

docker save ba0c2ff8d362 > mongo.tar

将文件拷贝到目标机器

导入 docker load < file.tar

docker load < mongo.tar

docker load < mongo.tar

导入镜像没有tag，需要自己指定

docker images

docker images
REPOSITORY   TAG       IMAGE ID       CREATED        SIZE
<none>       <none>    ba0c2ff8d362   7 months ago   492MB

docker tag [IMAGE ID] tag:version

docker tag ba0c2ff8d362 mongo

启动

docker run -itd --restart=always --name mongo1 -p 27001:27017 -v /data/mongodb_data:/data/db mongo:latest --replSet test
