安装docker:

yum install docker-ce

创建docker-compose.yml:

version: '3'

services:
  traefik:
    # The official v2 Traefik docker image
    image: traefik:v2.10
    # Enables the web UI and tells Traefik to listen to docker
    command: --api.insecure=true --providers.docker
    ports:
      # The HTTP port
      - "80:80"
      # The Web UI (enabled by --api.insecure=true)
      - "8080:8080"
    volumes:
      # So that Traefik can listen to the Docker events
      - /var/run/docker.sock:/var/run/docker.socky

 

附nginx.config:

server
{
    listen 80;
    server_name _;
    index index.html index.htm index.php;
    root  /data; 

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
    }

    location ~ .*\.(js|css)?$
    {
        expires      12h;
    }

    location ~ /\.
    {
        deny all;
    }

}

放证书的 dynamic.yml:

tls:
  certificates:
    - certFile: "/etc/certs/hk.peos.cn.cer"
      keyFile: "/etc/certs/hk.peos.cn.key"

 

 

启动traefik:

docker compose up -d

 

访问dashboard:   http://localhost:8080

 

支持各种插件：

 

Traefik 检测新服务并为您创建router

现在我们已经启动并运行了一个 Traefik 实例，我们将部署新服务。

编辑文件并在文件末尾添加以下内容。docker-compose.yml:

version: '3'
services:
  whoami:
    # A container that exposes an API to show its IP address
    image: traefik/whoami
    labels:
      - "traefik.http.routers.whoami.rule=Host(`whoami.docker.localhost`)"

上面的定义：一个简单的Web服务，输出有关部署它的机器的信息（其IP地址，主机等）。whoami

使用以下命令启动服务：whoami

docker-compose up -d whoami

返回浏览器 （http://localhost:8080/api/rawdata），看到 Traefik 已自动检测到新容器并更新了自己的配置。 

当 Traefik 检测到新服务时，它会创建相应的路由，以便您可以调用它们......我看看！（在这里，我们使用卷曲）

curl -H Host:whoami.docker.localhost http://127.0.0.1

Shows the following output:

<span class="hljs-attr">Hostname:</span> <span class="hljs-string">a656c8ddca6c</span>
<span class="hljs-attr">IP:</span> <span class="hljs-number">172.27</span><span class="hljs-number">.0</span><span class="hljs-number">.3</span>
<span class="hljs-comment">#...</span>

测试滚动更新：

先修改一image标签：

docker image tag traefik/whoami whoami:v2.0

再修改docker-compose中image为：whoami:v2.0

再更新：

docker compose up -d
