1️⃣ Docker daemon 配置代理（推荐）

Nginx TLS SNI routing, based on subdomain pattern

Nginx can be configured to route to a backend, based on the server's domain name, which is included in the SSL/TLS handshake (Server Name Indication, SNI).
This works for http upstream servers, but also for other protocols, that can be secured with TLS.

prerequisites

at least nginx 1.15.9 to use variables in ssl_certificate and ssl_certificate_key.
check nginx -V for the following:
```
...
TLS SNI support enabled
```

	package main

	import (
	"database/sql"
	"database/sql/driver"
	"fmt"
	"net"
	"os"
	"time"

	# Image neeeds to have ssh-client
	image: docker:git

	services:
	- docker:dind

	stages:
	- staging
	before_script:
	- docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN $CI_REGISTRY

	package main

	import (
	"crypto/tls"
	"crypto/x509"
