Usage:  docker load [OPTIONS]

Load an image from a tar archive or STDIN

Aliases:
  docker image load, docker load

Options:
  -i, --input string   Read from tar archive file, instead of STDIN
  -q, --quiet          Suppress the load output
[root@vm249 9.8.0.4.1]#

默认从标准输入STDIN

[root@vm249 9.8.0.4.1]docker image ls

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

重复load会在校验后立即完成，不会出现多个

[root@vm249 9.8.0.4.1]# docker load -i gcdw-operator-9.8.0.4.1-202304231127.tar
Loaded image: 192.168.8.84/gcdw/gcdw-operator:9.8.0.4.1
[root@vm249 9.8.0.4.1]#

-q

只输出load结果，没有load进度的过程显示。

[root@vm249 9.8.0.4.1]# docker load -i saas-vsftpd-202304231128.tar -q
Loaded image: 192.168.8.84/gcdw/vsftpd:latest
