大家好,又见面了,我是你们的朋友全栈君。
1.安装docker shell脚本
#!/bin/bash
hub_docker="hub.dy.com"
yum install -y epel-release docker
sed -i "s#--selinux-enabled --log-driver=journald#--selinux-enabled=false --insecure-registry $hub_docker:5000 --log-driver=json-file --storage-driver=overlay2#g" /etc/sysconfig/docker
# 开机自启
/usr/bin/systemctl daemon-reload
/usr/bin/systemctl enable docker
/usr/bin/systemctl start docker
2.私服的搭建 shell脚本
#!/bin/bash
docker pull registry
[ -d /home/registry ] || mkdir -p /home/registry
cat <<EOF >/home/registry/config.yml
version: 0.1
log:
fields:
service: registry
storage:
delete:
enabled: true
cache:
blobdescriptor: inmemory
filesystem:
rootdirectory: /var/lib/registry
http:
addr: :5000
headers:
X-Content-Type-Options: [nosniff]
health:
storagedriver:
enabled: true
interval: 10s
threshold: 3
EOF
docker run -itd -v /home/registry/:/var/lib/registry/ -v /home/registry/config.yml:/etc/docker/registry/config.yml -p 5000:5000 --restart=always --privileged=true --name registry registry
3.删除私库里面的镜像 shell脚本
#!/bin/bash
docker_name="$1"
docker_tag="$2"
docker_hub_url="hub.dy.com:5000"
docker_registry_container_id=`docker ps |grep registry |awk '{print $1}'`
if [ "$docker_tag" = "" ]; then
docker_tag="latest"
fi
#获取image的sha256
function get_docker_sha256(){
docker pull $docker_hub_url/$docker_name:$docker_tag > /dev/null 2>&1 #先下载下来 获取sha256
sha256=`docker inspect $docker_hub_url/$docker_name:$docker_tag | grep RepoDigests -A 5 | grep $docker_hub_url| grep sha256|awk -F '@' '{print $2}'|awk -F'"' '{print $1}'`
#docker rmi $docker_hub_url/$docker_name:$docker_tag #然后删除本地镜像 是否删除
echo $sha256
}
#删除镜像索引
function delete_images_index(){
sha256=`get_docker_sha256`
echo $sha256
curl -I -X DELETE http://$docker_hub_url/v2/$docker_name/manifests/$sha256
}
#删除镜像数据
function delete_images_data(){
docker exec -it $docker_registry_container_id registry garbage-collect /etc/docker/registry/config.yml
}
function main()
{
delete_images_index
delete_images_data
systemctl restart docker #重启docker 否则再次push 已经删除的镜像会出错
}
main
4.打印私库里面的所有镜像 shell脚本
#!/bin/bash
#本脚本可以打印私有镜像库中所有的镜像
#私有镜像库地址
HUB_URL=hub.dy.com:5000
#取得所有私有镜像库的所有镜像
IMAGESLIST=$(curl -s http://${HUB_URL}/v2/_catalog)
#echo ${IMAGESLIST}
#删除后2个字符
IMAGESLIST=${IMAGESLIST::-2}
#删除前面17个字符
IMAGESLIST=${IMAGESLIST:17}
#echo ${IMAGESLIST}
#要将$a分割开,先存储旧的分隔符
OLD_IFS="$IFS"
#设置分隔符
IFS=","
#如下会自动分隔
arr=($IMAGESLIST)
#遍历数组
for IMAGENAME in ${arr[@]}
do
#去掉引号
IMAGENAME=${IMAGENAME:1}
IMAGENAME=${IMAGENAME::-1}
#echo $IMAGENAME
S1=$(curl -s http://${HUB_URL}/v2/${IMAGENAME}/tags/list)
#取得[]中间的版本列表
S1=${S1#*[}
S1=${S1%]*}
#echo $S1
arr1=($S1)
#遍历数组
for VAR in ${arr1[@]}
do
#去掉引号
VAR=${VAR:1}
VAR=${VAR::-1}
echo $HUB_URL/$IMAGENAME:$VAR
done
done
#恢复原来的分隔符
IFS="$OLD_IFS"
