删除不掉镜像
docker image inspect --format=‘{{.RepoTags}} {{.Id}} {{.Parent}}’ $(docker image ls -q --filter since=5a64b7c87a1a)

自动清理镜像脚本

####自动清理脚本，若是harbor用的https，则将脚本中http改为https####

# yum install jq -y
jq：主要是用于shell与json结合，实现将数据输出为json，便于处理
# cat hub_image_clean.sh

#!/bin/bash
set -e
HARBOR_URL=192.168.0.58
HARBOR_PASSWD=Harbor12345
OLD_VERSION_NUM=4

function get_repos_list(){
  repos_list=$(curl -s -k -u admin:${HARBOR_PASSWD} http://${HARBOR_URL}/api/projects?page=1&page_size=50)
  mkdir -p $PWD/reposList
  echo "${repos_list}" | jq '.[]' | jq -r '.project_id' > $PWD/reposList/reposList.txt
}
function get_images_list(){
  mkdir -p $PWD/imagesList
  for repo in $(cat $PWD/reposList/reposList.txt);do
    images_list=$(curl -s -k -u admin:${HARBOR_PASSWD} http://${HARBOR_URL}/api/repositories?project_id=${repo})
    echo "${images_list}" | jq '.[]' | jq -r '.name' > $PWD/imagesList/${repo}.txt
  done

  #### images num
  num=$(echo "${htmlinfo}" | jq "length - ${OLD_VERSION_NUM}")
  if [[ "${num}" -le "0" ]]; then
    echo "$1 has no need of cleanup!!!"
    return
  fi

# for index in $(seq 0 ${num}); do

    echo "images=$1 ************************** tag= ${tag}"
    curl -s -k -u admin:${HARBOR_PASSWD} -X DELETE http://${HARBOR_URL}/api/repositories/$1/tags/${tag}
  done
}
