TLS握手错误

Question

我已经设置了一个使用自签名证书的docker注册表，但是我收到了这个错误。这次握手错误是什么意思？每当我尝试将图像推送到我的注册表时，日志就会增加。 （这是关于tls的我的注册表的日志）

$ docker logs 30273f6ed90f | grep tls

Answer 1

很难理解你如何使用问题中提供的有限上下文访问Docker注册表，但是看看Go代码（因为Docker是用Go编写的）：https://golang.org/src/crypto/tls/conn.go，你用来连接Docker注册表的客户端没有访问注册表使用HTTPS。

根据错误，您需要使用启用了TLS的客户端访问docker注册表，该客户端使用由相同的自签名CA信任的证书，该证书用于为Docker注册表创建证书。

Answer 2

尝试使用443端口：

svr := &http.Server{
    Addr: ":443",
    Handler: smux,
}

svr.ListenAndServeTLS("cert.pem", "key.pem")
