查看镜像仓库中应用的tag
通过docker search centos,查看到了centos的镜像,但是不知道仓库中这个镜像有多少可用的tag。通过一下的命令可以查看到。
[admin@controller-server ~]$ curl https://registry.hub.docker.com/v1/repositories/centos/tags| tr -d '[\[\]" ]' | tr '}' '\n'| awk -F: -v image='centos' '{if(NR!=NF && $3 != ""){printf("%s:%s\n",image,$3)}}'% Total % Received % Xferd Average Speed Time Time Time CurrentDload Upload Total Spent Left Speed100 1745 0 1745 0 0 1669 0 --:--:-- 0:00:01 --:--:-- 1669centos:latestcentos:5centos:6centos:6.10centos:6.6centos:6.7centos:6.8centos:6.9centos:7centos:7.0.1406centos:7.1.1503centos:7.2.1511centos:7.3.1611centos:7.4.1708centos:7.5.1804centos:7.6.1810centos:7.7.1908centos:7.8.2003centos:7.9.2009centos:8centos:8.1.1911centos:8.2.2004centos:8.3.2011centos:8.4.2105centos:centos5centos:centos5.11centos:centos6centos:centos6.10centos:centos6.6centos:centos6.7centos:centos6.8centos:centos6.9centos:centos7centos:centos7.0.1406centos:centos7.1.1503centos:centos7.2.1511centos:centos7.3.1611centos:centos7.4.1708centos:centos7.5.1804centos:centos7.6.1810centos:centos7.7.1908centos:centos7.8.2003centos:centos7.9.2009centos:centos8centos:centos8.1.1911centos:centos8.2.2004centos:centos8.3.2011centos:centos8.4.2105
