配置harbor http方式

cat harbor.yml 
# Configuration file of Harbor

# The IP address or hostname to access admin UI and registry service.
# DO NOT use localhost or 127.0.0.1, because Harbor needs to be accessed by external clients.
hostname: mini1

# http related config
http:
  # port for http, default is 80. If https enabled, this port will redirect to https port
  port: 80

# https related config
# https:
#   # https port for harbor, default is 443
#   port: 443
#   # The path of cert and key files for nginx
#   certificate: /your/certificate/path
#   private_key: /your/private/key/path

# Uncomment external_url if you want to enable external proxy
# And when it enabled the hostname will no longer used
external_url: http://mini1

# The initial password of Harbor admin
# It only works in first time to install harbor
# Remember Change the admin password from UI after launching Harbor.
harbor_admin_password: Harbor12345

# Harbor DB configuration  物理机mysql密码
database: 
  # The password for the root user of Harbor DB. Change this before any production use.
  password: 123456

# The default data volume
data_volume: /data

docker push 到harbor，正确的操作方法

1.cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://qgcuuo71.mirror.aliyuncs.com"],
"insecure-registries": ["http://mini1:80"]
}
2.docker login http://mini1:80 -注意端口必须写80
3.docker pull mini1:80/dev/ngx:v1 -注意端口必须写80
4.docker tag mini1/dev/jdk1.8:v2 mini1:80/dev/jdk1.8:v3 -注意端口必须写80
5.docker push mini1:80/dev/jdk1.8:v3 -注意端口必须写80

上传成功如图：

总结：

harbor对http方式支持不太好，哪个用户创建的仓库，使用哪个用户push pull
login pull push tag 操作必须带上mini1:80进行操作,才能操作成功
