[root@localhost～]#docker tag tomcat7 192.168.1.23:5000/tomcat7
s3: and the client establishes connection with the private warehouse and judges whether the software service mirror image exists in the private warehouse or not.
When the software service mirror image is released, whether the software service mirror image exists in the private warehouse needs to be judged firstly, and if the private warehouse does not have the software service mirror image, the client cannot download the mirror image from the private warehouse. The code can be used for:
[root@localhost～]#curl-XGET http://192.168.1.23:5000/v2/_catalog
i.e., indicating the existence of the tomcat7 mirror in the private warehouse. Or using browser access (103.110.186.23 is the registry's extranet ip, 5000 port access is opened in the iptables firewall):
http://103.110.186.23:5000/v2/_catalog
http://103.110.186.23:5000/v2/tomcat7/tags/list
for example, local tomcat7 and 192.168.1.23:5000/tomcat7 images may both be deleted and then downloaded from a private repository.
S4: and if and only if the software service image exists in the private warehouse, the client downloads the software service image from the private warehouse and uses the software service image.
In the embodiment of the invention, if and only if the software service mirror image exists in the private warehouse, the client downloads the software service mirror image from the private warehouse and uses the software service mirror image, specifically:
when the software service mirror image exists in the warehouse, the client downloads the software service mirror image from the private warehouse and uses the software service mirror image;
and ending when the software service image does not exist in the warehouse.
