linuxea:nexus3排序清理docker镜像列表 nexus3的出现可以替代很多产品，nexus3整合了常用的功能，比如docker镜像仓库等。一般我们在配置docker仓库的时候，在blob stores中创建的新的stores来存储镜像。这样方便管理早期的nexus-cli已经没有维护，nexus-cli删除的镜像并没有按照时间的顺序进行保留 。需要在13rentgen的仓库中下载修复版的，所以你需要下载最新的进行使用登录nexus下载最新的修复版本https://github.com/13rentgen/nexus-cli/releases/tag/v1.1.0这里演示用的是旧的版本[root@nexus ]# ./nexus-cli --version Nexus CLI version 1.0.0-beta登录nexus[root@nexus ~]# nexus-cli configure Enter Nexus Host: http://127.0.0.1:38081 Enter Nexus Repository Name: docker-host Enter Nexus Username: admin Enter Nexus Password: yxt@..123!com列出镜像[root@nexus ~]# nexus-cli image ls删除命令nexus-cli image delete -name IMAGE_NAME -keep X，-keep X 表示保留几个tag如果是单个删除，那么命令如下nexus-cli image delete -name dnotask1 -keep 10 nexus-cli image delete -name outage2 -keep 10 nexus-cli image delete -name 1speed -keep 10 nexus-cli image delete -name mongo2 -keep 10 nexus-cli image delete -name mongo1 -keep 10清理脚本#!/bin/bash # Copyright 2022 marksugar, personal # 2022 linuxea.com # Author: mark <usertzc#163.com> USER=admin PASS="password" REPO=docker-host HOST="http://127.0.0.1:38081" CLEAN_DISK_NAME=/data/ touchnet(){ local recode=`curl -o /dev/null -s --connect-timeout 3 $1 -w %{http_code}` if [ "$recode" == "200" ]; then return 1 fi } Create_CRE(){ # protect file since it contains secrets touch ~/.credentials && chmod 600 ~/.credentials # update file using environment variables cat << _EOF > ~/.credentials # Nexus Credentials nexus_host = "${HOST}" nexus_username = "${USER}" nexus_password = "${PASS}" nexus_repository = "${REPO}" _EOF } touchnet ${HOST} if [ `echo $?` == "1" ]; then [ -f ~/.credentials ] || Create_CRE ; else echo "Cannot communicate with the ${HOST}";exit -1; fi PATHS=yxt-vehicle PATH_NAME="dnotask1 outage21speed mongo2 mongo1" TAKE_NUM=10 type nexus-cli > /dev/null 2>&1 && echo " nexus-cli is ok" || { echo "error nexus-cli is not install";exit -1 ;} if [ `df -hT ${CLEAN_DISK_NAME} | tail -1| awk '{print $6}'| awk -F% '{print $1}'` -gt 80 ];then for i in `echo ${PATH_NAME}`;do echo -e "\033[34m $i Start cleaning, keep the last 10 \033[0m" && nexus-cli image delete -name ${PATHS}/${i} -keep ${TAKE_NUM} ;done fi清理完成后进行删除Tasks --> create task --> delete unused manifests and images Task执行完就消失了Tasks --> create task ---> compact blob store Task而后指定store清理Compact blob store。
