I'm trying to connect two mongodb containers running on docker using docker-compose
. One container seed some data to the other using mongoimport
.
However, I'm getting the following error when run mongoimport
Failed: error connecting to db server: no reachable servers
I can actually reach the mongodb
container from mongo-seed
since I'd appended a ping -c 3 mongodb
to the CMD
and the container can resolve successfully that hostname.
Below the files I'm using:
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": "[email protected]",
"age": 40,
"admin": false
},
{
"name": "Jen Ford",
"email": "[email protected]",
"age": 45,
"admin": true
}
]
And this the output of docker-compose up
:

Any idea? What am I missing?
