問題：

[root@win82 win81.inno.com]# docker push win81.inno.com:443/test/busybox
Using default tag: latest
The push refers to repository [win81.inno.com:443/test/busybox]
Get https://win81.inno.com:443/v2/: x509: certificate signed by unknown authority

解決：

將harbor 的主機crt 放到要push 的主機目錄/etc/pki/ca-trust/source/anchors/
[root@win81 cert]# 
 
pwd
/data/cert
[root@win81 cert]# scp -p win81.inno.com.crt win82:/etc/pki/ca-trust/source/anchors/
win81.inno.com.crt                                                                                                                        100% 2126     1.0MB/s   00:00 

在push 主機上更新
[root@win82 certs]# update-ca-trust
