镜像的导入和导出

批量打包镜像:
# docker save $(docker images | grep -v REPOSITORY | awk 'BEGIN{OFS=":";ORS=" "}{print $1,$2}') -o k8s-master.tar

导入镜像：
# docker load -i k8s-master.tar

-------------------------------------------------------------------------
#批量修改images的原有库上传到新库
#!/bin/bash

readonly old_repo=harbor.cetccloud.com/amd64
readonly new_repo=harbor.cetccloud.com/amd64

for image in $(docker images --format '{{.Repository}}:{{.Tag}}'); do
    name=${image##*/}
    new_img=${new_repo}/${name}
    echo "Processing ${image} -> ${new_img}"
    sudo docker tag ${image} ${new_img}
    sudo docker push ${new_img}
    sudo docker rmi ${new_img}
done
----------------------------------------------------------------
##批量save images镜像
#!/bin/bash
#Output the information of images to images.txt
sudo docker image ls >images.txt
#Get the number of images according to the total of content's rows 
N=$(awk 'END{print NR}' images.txt)
echo The total of images is $N
#Get names and tags of images
for ((i=2; i<=$N; i++))
  do
    image=$(awk 'NR=="'"$i"'" {print $1}' images.txt)
    version=$(awk 'NR=="'"$i"'" {print $2}' images.txt)
#Modify the name of files which will be saved in local , otherwise you will be failed to save images.
    shortname=`echo $image | sed 's/.*///g'`
#filename is name of the file that will be saved
    filename="${shortname}-${version}.tar"
    imagename="${image}:${version}"

#Output the value of variable
    echo image=$image
    echo version=$version
    echo filename=$filename
    echo imagename=$imagename
    echo shortname=$shortname

#Save the image as a local tar file
    sudo docker save -o $filename $imagename
#Modify the permission of the file
    sudo chmod 755 $filename
#Output the result!
    echo No.$i $shortname is saved successfully！
  done
#Delete file
rm images.txt

##批量导入 images镜像
#!/bin/bash
for i in *tar
  do sudo docker load -i $i
done
--------------------------------------------------------------------
###批量pull harbor库中的镜像
#curl -X GET --header 'Accept: application/json' 'https://harbor.cetccloud.com/api/search?q=amd64'
目的是获取amd64的project_id=多少，替换到脚本里面
amd64可以换harbor里其他仓库名

#!/bin/bash
URL="https://harbor.cetccloud.com"
IP="harbor.cetccloud.com"
USER="deploy"
PASS="Wg7FPtHbAB"
REPOS=$(curl -s -X GET --header 'Accept: application/json' "${URL}/api/repositories?project_id=9"|grep "name"|awk -F '"' '{print $4}')
for rp in ${REPOS}
do
  TAGS=$(curl -s -X GET --header 'Accept: application/json' "${URL}/api/repositories/${rp}/tags"|grep "name"|awk -F '"' '{print $4}'|sort -r)
  a=$(echo ${rp}|awk -F "/" '{print $2}')
    for t in ${TAGS}
    do
        docker pull ${IP}"/"${rp}":"${t}
        echo ${IP}"/"${rp}":"${t} >> /opt/docker.tag
        docker save ${IP}"/"${rp}":"${t} > /opt/docker/${IP}-${a}-${t}.tar.gz
    done
    echo "===================="
done

1、删除所有容器

docker rm `docker ps -a -q`

2、删除所有镜像

docker rmi `docker images -q`

3、按条件删除镜像

docker rmi `docker images -q | awk '/^<none>/ { print $3 }'`

docker rmi --force `docker images | grep doss-api | awk '{print $3}'`    //其中doss-api为关键字
