導出鏡像：image-save.sh

導入鏡像：image-load.sh

#!/bin/bash ##用法： #image-load.sh --images-path images-2020-03-19# 定義日志 workdir=`pwd` log_file=${workdir}/sync_images_$(date +"%Y-%m-%d").loglogger() {log=$1cur_time='['$(date +"%Y-%m-%d %H:%M:%S")']'echo ${cur_time} ${log} | tee -a ${log_file} }POSITIONAL=() while [[ $# -gt 0 ]]; dokey="$1"case $key in-i|--images-path)images_path="$2"shift # past argumentshift # past value;;-l|--image-list)list="$2"shift # past argumentshift # past value;;-h|--help)help="true"shift;;esac doneusage () {echo "USAGE: $0 [--image-list images.txt] [--images images.tar.gz]"echo " [-l|--images-list path] text file with list of images. 1 per line."echo " [-l|--images path] tar.gz generated by docker save."echo " [-h|--help] Usage message" }if [[ $help ]]; thenusageexit 0 fi#set -e -x# 鏡像壓縮文件列表 images=$(cat images.txt |sed "s#/#-#g; s#:#-#g") #images_path=images-$(date +"%Y-%m-%d") images_path=images-prometheus-optrator cd $images_path# 導入鏡像 docker_load () {for imgs in $(echo ${images});dogunzip -c ${imgs}.tgz | docker load >/dev/null 2>&1if [ $? -ne 0 ]; thenlogger "${imgs} load failed."elselogger "${imgs} load successfully."fidone } docker_load cd ..
