我正在尝试使用来连接在docker上运行的两个mongodb容器docker- compose。一个容器使用将种子中的数据提供给另一个容器mongoimport。
docker- compose
mongoimport
但是,运行时出现以下错误 mongoimport
Failed: error connecting to db server: no reachable servers
实际上,我可以mongodb从到达容器,mongo-seed因为我将追加了ping -c 3 mongodb,CMD并且容器可以成功解析该主机名。
mongodb
mongo-seed
ping -c 3 mongodb
CMD
在我正在使用的文件下面:
docker-compose.yml
version: '2' services: mongodb: image: mongo:3.2 ports: - "27017:27017" mongo-seed: build: ./mongo-seed
mongo-seed / Dockerfile
FROM mongo:3.2 COPY init.json /init.json CMD ping -c 3 mongodb && mongoimport --host mongodb --db test --collection users \ --type json --file /init.json --jsonArray
mongo-seed / init.json
[ { "name": "Joe Smith", "email": "jsmith@gmail.com", "age": 40, "admin": false }, { "name": "Jen Ford", "email": "jford@gmail.com", "age": 45, "admin": true } ]
这是输出docker-compose up:
docker-compose up

任何的想法?我想念什么?
我终于可以设法连接两个容器。我的发现是出于文档目的。
docker-compose
bridge
mongod
127.0.0.1
network
--bind_ip
