How can I use Custom TLSConfig with AutoTLS?

[eranchetz]

I am trying to disable TLS 1.0 and 1.1,
I am currently using echo.StartAutoTLS(addr),
what is the right/best way to pass &TLSConfig object?

Echo docs have example for autoTLS https://echo.labstack.com/cookbook/auto-tls/#server see customHTTPServer function there

I would recommend using http.Server + autocert.Manager as it allows you to customize more aspects of server.

func main() { e := echo.New() e.Use(middleware.Recover()) e.Use(middleware.Logger()) e.GET("/", func(c echo.Context) error { return c.HTML(http.StatusOK, ` <h1>Welcome to Echo!</h1> <h3>TLS certificates automatically installed from Let's Encrypt :)</h3> `)	}) autoTLSManager := autocert.Manager{ Prompt: autocert.AcceptTOS, // Cache certificates to avoid issues with rate limits (https://letsencrypt.org/docs/rate-limits) Cache: autocert.DirCache("/var/www/.cache"), //HostPolicy: autocert.HostWhitelist("<DOMAIN>"),	} s := http.Server{ Addr: ":443", Handler: e, // set Echo as handler TLSConfig: &tls.Config{ //Certificates: nil, // <-- s.ListenAndServeTLS will populate this field GetCertificate: autoTLSManager.GetCertificate, NextProtos: []string{acme.ALPNProto},	}, //ReadTimeout: 30 * time.Second, // use custom timeouts	} if err := s.ListenAndServeTLS("", ""); err != http.ErrServerClosed { e.Logger.Fatal(err)	} }
