泊塢窗網：失敗ADRESS多主機網絡

Question

由名容器我有3臺主機上運行的有羣簇，使用覆蓋網絡在它搬運工1.11

機都採用boot2docker和VirtualBox的開始：

docker-machine create -d virtualbox af-consul 
docker run -d -p "8500:8500" -h "consul" progrium/consul -server -bootstrap 

docker-machine create -d virtualbox --virtualbox-memory 4096 \ 
--swarm \ 
--swarm-discovery="consul://$(docker-machine ip af-consul):8500" \ 
--engine-opt="cluster-store=consul://$(docker-machine ip af-consul):8500" \ 
--engine-opt="cluster-advertise=eth0:2376" af-repo 

docker-machine create -d virtualbox --virtualbox-memory 4096 --swarm --swarm-master \ 
--swarm-discovery="consul://$(docker-machine ip af-consul):8500" \ 
--engine-opt="cluster-store=consul://$(docker-machine ip af-consul):8500" \ 
--engine-opt="cluster-advertise=eth0:2376" af-jenkins 

網絡創建這樣的：

eval $(docker-machine env --swarm af-jenkins) 
docker network create -d overlay appfactory_overlay 

然後容器的部署使用的是完成撰寫：

version: '2' 
jenkins: 
    user: root 
    restart: always 
    image: af-repo:5000/jenkins:latest 
    # build: ./jenkins 
    container_name: jenkins 
    ports: 
     - "8080:8080" 
     - "50000:50000" 
    networks: 
     - appfactory_overlay 
    volumes_from: 
     - container:jenkins_data:rw 
    environment: 
     - "constraint:node==af-jenkins" 
    external_links: 
     - jenkins_data 

    docker_registry: 
     user: root 
     container_name: docker_registry 
     restart: always 
     build: ./ 
     ports: 
      - 5000:5000 
     networks: 
      - appfactory_overlay 
     environment: 
      REGISTRY_HTTP_TLS_CERTIFICATE: /etc/ssl/certs/domain.crt 
      REGISTRY_HTTP_TLS_KEY: /etc/ssl/certs/domain.key 
      constraint: "node==af-repo" 

    reports: 
     user: root 
     restart: always 
     image: httpd:2.4 
     container_name: reports 
     ports: 
     - "2222:22" 
     - "80:80" 
     volumes_from: 
      - container:repository_data:rw 
     networks: 
      - appfactory_overlay 
     environment: 
      - "constraint:node==af-repo" 

networks: 
    appfactory_overlay: 
    external: 
     name: appfactory_overlay 

當我ssh到AF-回購和EXEC在報告容器/斌/慶典我可以ping docker_registry容器，它是在同一主機上：

root@74068f00ffdb:/usr/local/apache2# ping docker_registry 
PING docker_registry (10.0.0.2): 56 data bytes 
64 bytes from 10.0.0.2: icmp_seq=6 ttl=64 time=0.157 ms 
64 bytes from 10.0.0.2: icmp_seq=7 ttl=64 time=0.126 ms

64 bytes from 10.0.0.2: icmp_seq=9 ttl=64 time=0.132 ms 

但是，當我嘗試ping詹金斯容器，這是另一臺主機上：

root@74068f00ffdb:/usr/local/apache2# ping jenkins 
PING jenkins (10.0.0.5): 56 data bytes 
92 bytes from 74068f00ffdb (10.0.0.4): Destination Host Unreachable

網絡似乎是正確的，當我檢查它：

] 

從af-jenkins做起時輸出是一樣的。 因此，據我所知，我的網絡根本不工作，因爲我從同一主機上的另一個容器ping容器的能力來自於爲這些容器自動創建的橋接網絡。

任何幫助，不勝感激:)

Answer 1

當使用泊塢窗機，VirtualBox虛擬的「主機唯一的」接口eth1的，請嘗試更改集羣廣告設置使用eth1的來代替。 - slugonamission

謝謝。

Answer 2

我覺得，你的問題是，你是不是指向你docker CLI到集羣。在創建覆蓋網絡之前，您必須使用標記--swarm連接到羣集羣。

eval $(docker-machine env --swarm af-jenkins) 

如果這不是問題，讓我們知道了什麼是docker info命令的集羣中的輸出。

注意：使用docker 1.12.0可以簡化創建羣集的過程。
