今天在AWS云主机上部署Grafana，发现无法使用私有仓库，于是，尝试了下docker save和docker load。着实很好用，简单记录下：
docker save用法：
Usage: docker save [OPTIONS] IMAGE [IMAGE...] Save one or more images to a tar archive (streamed to STDOUT by default) Options: -o, --output string Write to a file, instead of STDOUT
docker save -o your_path/image.tar image_name:tag
docker load用法：
docker load -i image.tar
Usage: docker load [OPTIONS] Load an image from a tar archive or STDIN Options: -i, --input string Read from tar archive file, instead of STDIN -q, --quiet Suppress the load output
scp携带证书传输：
scp -i "your_certificatefile" local_folder remote_username@host:remote_folder
