docker-tags 命令行获取docker远程仓库上指定镜像的tag列表
说明
用于命令行获取docker远程仓库上指定镜像的所有tag列表，支持版本号模糊搜索，可与docker search配合搜索。
1.脚本
#!/bin/bash
API="https://registry.hub.docker.com/v1/repositories"
DEFAULT_NAME="nginx"
DEFAULT_TIMEOUT=3
function Usage(){
cat << HELP
Usage: docker-tags NAME[:TAG]
docker-tags list all tags for docker image on a remote registry.
Example:
docker-tags (default nginx)
docker-tags nginx
docker-tags nginx:1.15.8
docker search nginx | docker-tags
docker search nginx | docker-tags :1.15.8
echo nginx | docker-tags
echo nginx | docker-tags :1.15.8
HELP
}
ARG=$1
if [[ "$ARG" =~ "-h" ]];then
Usage
exit 0
fi
function ParseJson(){
tr -d '[\[\]" ]' | tr '}' '\n' | awk -F: -v image=$1 '{if(NR!=NF && $3 != ""){printf("%s:%s\n",image,$3)}}'
}
function GetTags(){
image=$1
tag=$2
ret=`curl -s ${API}/${image}/tags`
tag_list=`echo $ret | ParseJson ${image}`
if [ -z "$tag" ];then
echo -e "$tag_list"
else
echo -e "$tag_list" | grep -w "$tag"
fi
}
if [ -z $ARG ] || [[ ${ARG:0:1} == ":" ]];then
if [ -x /usr/bin/timeout ];then
images=`timeout $DEFAULT_TIMEOUT` awk '{print $1}' | grep -v "NAME" || echo $DEFAULT_NAME
else
images=`awk '{print $1}' | grep -v "NAME"`
fi
else
images=`echo $ARG | awk -F: '{print $1}'`
fi
tag=`echo $ARG | awk -F: '{print $2}'`
for i in ${images}
do
tags=`GetTags $i $tag`
count=`echo $tags | wc -w`
if [[ $count -gt 0 ]];then
echo -e "IMAGE [$i:$tag]:"
echo -e "$tags"
echo
fi
done
