Production machines are generally no external network environment, so docker needs to be installed offline, and the image also needs to be installed offline.
Therefore, you need a machine connected to the Internet. First download the image and then export it.

Export
Export and package the downloaded image, upload it to an offline server, and import it.
docker save -o /Users/hyl/Desktop/jk/influxdb.tar influxdb:1.8 docker save -o /Users/hyl/Desktop/jk/grafana.tar grafana/grafana:latest
The operation is as follows:
The export process may take some time, depending on the size of the image, so be patient.
Import image
After the export is complete, you can use the docker load command to verify the exported image. The following is an example command to load an image:
[root@hadoop01 ~]# docker load -i ./influxdb.tar 53ae7e5bcde8: Loading layer [================================================ =====>] 129.4MB/129.4MB 47a0492361a1: Loading layer [================================================ =====>] 29.53MB/29.53MB ea498917da7b: Loading layer [================================================ =====>] 10.75kB/10.75kB 18ae329703f8: Loading layer [================================================ =====>] 154MB/154MB 63f6173a2112: Loading layer [================================================ =====>] 3.072kB/3.072kB 99108cfee517: Loading layer [================================================ =====>] 2.048kB/2.048kB 3ab566fe20ca: Loading layer [================================================ =====>] 5.632kB/5.632kB Loaded image: influxdb:1.8 [root@hadoop01 ~]# docker load -i ./grafana.tar 4693057ce236: Loading layer [================================================ =====>] 7.626MB/7.626MB bdf330023361: Loading layer [================================================ =====>] 2.56kB/2.56kB 018ee2d8caca: Loading layer [================================================ =====>] 8.495MB/8.495MB 7ccfea30313d: Loading layer [================================================ =====>] 10.19MB/10.19MB fb7a544ac307: Loading layer [================================================ =====>] 162.3kB/162.3kB 4ee20b1f5366: Loading layer [================================================ =====>] 89.6kB/89.6kB 5892380a6ea3: Loading layer [================================================ =====>] 189.1MB/189.1MB 3c537f66dd33: Loading layer [================================================ =====>] 191.2MB/191.2MB bf5a90fccd9f: Loading layer [================================================ =====>] 37.89kB/37.89kB e14e42fdf9d7: Loading layer [================================================ =====>] 5.12kB/5.12kB Loaded image: grafana/grafana:latest [root@hadoop01 ~]#
