docker buildx build 报错http: server gave HTTP response to HTTPS client

ERROR: failed to solve: 192.168.253.123:5000/backend-base:1.0.0: failed to resolve source metadata for 192.168.253.123:5000/backend-base:1.0.0: failed to do request: Head "https://192.168.253.123:5000/v2/backend-base/manifests/1.0.0": http: server gave HTTP response to HTTPS client

 原因分析：

1. 它默认去网址https请求元数据，但是自己搭建的仓库没提供https的服务；

 解决方法：

1、创建buildkitd.toml文件

修改为自己docker私有库的地址例如：192.168.253.123:5000

[registry."a.b.c:5000"]
  mirrors = ["a.b.c:5000"]
  http = true
  insecure = true

2、创建builder示例过程中加入config参数

docker buildx create --name muti-buildx --driver docker-container --use --config buildkitd.toml
