带有Traefik HTTPS重定向的Docker Swarm中的Tomcat应用服务器返回网关超时

Question

我是Tomcat，Docker和traefik的新手，并且被困在试图通过Traefik https重定向在单节点docker swarm中设置Tomcat应用程序服务器。目前，我可以看到Traefik Dashoard的所有后端和前端服务都在运行，但是我的网站本身和Adminer DBAdmin页面返回“网关超时”消息，并且什么也不显示。非常感谢您的帮助。提前致谢！以下是我执行的步骤和配置：

1。 Traefik.toml

<pre>
debug = false
checkNewVersion = true
logLevel = "ERROR"
InsecureSkipVerify = true

# Access log
filePath = "/var/log/traefik/access.log"
format = "common"

#Add named EntryPoints for HTTP and HTTPS
#that all backend have access to
defaultEntryPoints = ["http", "https"]

[entryPoints]
  [entryPoints.http]
    address = ":80"
     [entryPoints.http.redirect] #2nd Force HTTPS
       entryPoint = "https"
  [entryPoints.https]
    address = ":443"
     [entryPoints.https.tls]

# Configure the api provider on port 8080
#with basic authentication method
  [entryPoints.dashboard]
    address = ":8080"
     [entryPoints.dashboard.auth]
       [entryPoints.dashboard.auth.basic]
         users = ["myuser:$apr1$EbvR0Rs3cr8PRzQGp8a3Wt5apSROCP61"]

  [api]
  entrypoint="dashboard"

#Enable retry if network error
  [retry]

#Letsencrypt configuration with ACME HTTP challenge
  [acme]
  email = "mail@example.com"
  storage = "acme.json"
  entryPoint = "https"
  onHostRule = true
   [acme.httpChallenge]
   entryPoint = "http"
   [[acme.domains]]
    main = "EXAMPLE.COM"
  [[acme.domains]]
    main = "MONITOR.EXAMPLE.COM"
  [[acme.domains]]
    main = "DBADMIN.EXAMPLE.COM"

#Define Docker Backend Configuration
  [docker]
  domain = "example.com"
  network = "web"
  watch = true
<code>

2。创建网桥，acme.json文件（和chmod 600），然后使用以下命令创建traefik容器：

<pre>
docker run -d \
-v /var/run/docker.sock:/var/run/docker.sock \
-v $PWD/traefik.toml:/traefik.toml \
-v $PWD/acme.json:/acme.json \
-v traefikdata:/traefik \
-p 80:80 \
-p 443:443 \
-l traefik.enable=true \
-l traefik.frontend.rule=Host:monitor.example.com \
-l traefik.port=8080 \
--restart=always \
--network web \
--name traefik \
traefik:1.7.6-alpine
<code>

3。设置一群

<pre>
docker swarm init
<code>

4。创建可附加的覆盖网络

<pre>
docker network create --driver overlay --attachable <network-name>
<code>

5。将Traefik容器连接到覆盖网络

<pre>
docker network connect <network-name> <container-name>
<code>

1. 使用docker-compose.yml文件向Traefik注册容器

   version: "3.6"
   
   
   networks:
     frontend:
       driver: overlay
     backend:
   
   services:
     myapp:
       image: app/app
       deploy:
         replicas: 3
         restart_policy:
           condition: on-failure
       volumes:
         - "./sitedata:/path-to/htdoc/_data"
       environment:
         DB_NAME: "mydb"
         DB_USER: "dbuser"
         DB_PASSWORD: "secret"
       labels:
         - "traefik.enable=true"
         - traefik.backend=myapp
         - traefik.frontend.rule=Host:myapp.example.com
         - traefik.docker.network=frontend
         - traefik.port=80
       networks:
         - backend
         - frontend
       depends_on:
         - mydb
   
   mydb:
       image: myapp/db
       deploy:
         replicas: 3
         restart_policy:
           condition: on-failure
       volumes:
         - "./pgdata:/path-to/data/mydata"
       environment:
         POSTGRES_DB: 'mydb'
         POSTGRES_USER: 'dbuser'
         POSTGRES_PASSWORD: 'secret'
         PGDATA: /path-to/data/mydata
       networks:
         - backend
       labels:
         - traefik.enable=false # to specify that Traefik should not expose
   
   adminer:
       image: adminer:4.7-standalone
       deploy:
         replicas: 1
         restart_policy:
           condition: on-failure
       volumes:
         - "./path-to/data/data"
       labels:
         - "traefik.enable=true"
         - traefik.backend=adminer
         - traefik.frontend.rule=Host:dbadmin.example.com
         - traefik.docker.network=frontend
         - traefik.port=8080
       networks:
         - backend
         - frontend
       depends_on:
         - mydb
   

7. Run the containers

<pre> docker stack deploy -c docker-compose.yml myawesomeapp <code>

结果 ==========

此刻我只能看到我的Traefik仪表板

Traefik Dashboad

我的网站和dbadmin页面都返回“网关超时”消息

Gateway Timeout error from website, as well as, dbadmin page
