docker-compose up以“无法find满足以下条件的节点”
我docker-compose.yml是：
version: '2' services: db: build: ./postgres ports: - "5432:5432" volumes: - postgres-data:/data env_file: .env environment: - "constraint:node=edge" networks: - back-tier volumes: postgres-data: driver: local networks: back-tier: driver: overlay
我在google docker swarm中有两个节点。 我创build了以下内容：
## Swarm master docker-machine --debug create --driver google --google-project my_project --swarm --swarm-discovery="consul://$cip:8500" --engine-opt="cluster-store=consul://$cip:8500" --engine-opt="cluster-advertise=eth0:2376" --swarm-master --engine-label node=director --google-disk-size 100 --google-machine-type n1-standard-2 director ## Nodo edge docker-machine --debug create --driver google --google-project my_project --swarm --swarm-discovery="consul://$cip:8500" --engine-opt="cluster-store=consul://$cip:8500" --engine-opt="cluster-advertise=eth0:2376" --engine-label node=edge --google-scopes https://www.googleapis.com/auth/devstorage.read_write --google-disk-size 250 --google-machine-type n1-standard-4 node-0
我可以用docker-machine ls看到他们俩
consul - google Running tcp://XXXX:2376 v1.11.0 director * (swarm) google Running tcp://XXXX:2376 director (master) v1.11.0 node-0 - google Running tcp://XXXX:2376 director v1.11.0
labels工作：
$ docker-machine ls --filter label=node=edge NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS node-0 - google Running tcp://XXXX:2376 v1.11.0
docker info输出是
$ docker info Containers: 3 Running: 3 Paused: 0 Stopped: 0 Images: 4 Server Version: swarm/1.2.0 Role: primary Strategy: spread Filters: health, port, dependency, affinity, constraint Nodes: 2 director: 104.154.88.186:2376 └ Status: Healthy └ Containers: 2 └ Reserved CPUs: 0 / 2 └ Reserved Memory: 0 B / 7.67 GiB └ Labels: executiondriver=, kernelversion=4.2.0-18-generic, node=director, operatingsystem=Ubuntu 15.10, provider=google, storagedriver=aufs └ Error: (none) └ UpdatedAt: 2016-04-24T04:43:50Z └ ServerVersion: 1.11.0 node-0: 104.197.85.59:2376 └ Status: Healthy └ Containers: 1 └ Reserved CPUs: 0 / 4 └ Reserved Memory: 0 B / 15.42 GiB └ Labels: executiondriver=, kernelversion=4.2.0-18-generic, node=edge, operatingsystem=Ubuntu 15.10, provider=google, storagedriver=aufs └ Error: (none) └ UpdatedAt: 2016-04-24T04:43:41Z └ ServerVersion: 1.11.0 Plugins: Volume: Network: Kernel Version: 4.2.0-18-generic Operating System: linux Architecture: amd64 CPUs: 6 Total Memory: 23.09 GiB Name: director Docker Root Dir: Debug mode (client): false Debug mode (server): false WARNING: No kernel memory limit support
所以一切似乎都对，对吧？
但是当我尝试运行docker-compose up -d
发生以下情况：
$ docker-compose up -d Creating network "infraestructura_back-tier" with driver "overlay" Creating volume "infraestructura_postgres-data" with local driver Building db Step 1 : FROM postgres:9.5 ---> 0f3af79d8673 Step 2 : ADD create_tables.sql /docker-entrypoint-initdb.d ---> Using cache ---> 2f818eec1228 Successfully built 2f818eec1228 WARNING: Image for service db was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`. Creating infraestructura_db_1 ERROR: for db Unable to find a node that satisfies the following conditions [port 5432 (Bridge mode)]
除了删除"constraint:node=edge"之外，这种情况并不重要（尝试另一个映像，销毁和重新创build节点等）
我做错了什么？
顺便说一句，我的版本是：
$ docker version Client: Version: 1.11.0 API version: 1.23 Go version: go1.5.4 Git commit: 4dc5990 Built: Wed Apr 13 18:38:59 2016 OS/Arch: linux/amd64 Server: Version: swarm/1.2.0 API version: 1.22 Go version: go1.5.4 Git commit: a6c1f14 Built: Wed Apr 13 05:58:31 UTC 2016 OS/Arch: linux/amd64 $ docker-machine -v docker-machine version 0.6.0, build e27fb87 $ docker-compose -v docker-compose version 1.7.0, build 0d7bf73 $ docker run --rm swarm -version swarm version 1.2.0 (a6c1f14)
你可以尝试改变这一行：
- "constraint:node=edge"
至
- "constraint:node==edge"
错误提到端口5432 。
ERROR: for db Unable to find a node that satisfies the following conditions [port 5432 (Bridge mode)]
因此，在检查是否有一个端口5432打开的节点后，Docker失败。 你确定Postgres还没有在两个节点上运行，或者其他一些容器已经在5432端口上侦听？
你可以在创build新的容器之前用docker-compose rm来销毁旧的容器。
