docker 自建Registry後,將images檔push出去時會出現下以的錯誤:
     
  
  
root@docker:~# docker push 172.17.42.1:5000/httpd-dowdot
     
  
  
Error response from daemon: invalid registry endpoint https://172.17.42.1:5000/v0/: unable to ping registry endpoint https://172.17.42.1:5000/v0/
     
  
  
v2 ping attempt failed with error: Get https://172.17.42.1:5000/v2/: EOF
     
  
  
v1 ping attempt failed with error: Get https://172.17.42.1:5000/v1/_ping: EOF. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add –insecure-registry 172.17.42.1:5000 to the daemon’s arguments. In the case of HTTPS, if you have access to the registry’s CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/172.17.42.1:5000/ca.crt
        
  
  
解法:
     
  
  
在/etc/default/docker加入以下參數,再把docker服務重啟就可以了
     
  
  
DOCKER_OPTS=”$DOCKER_OPTS –insecure-registry=172.17.42.1:5000″
