I have two different services running in a single docker-compose file. I talk to each service by referring to the service name of the containers.
Now I want my container A to access localhost as well. For this when I added the configuration of 'network_mode=host', but this creates an error now stating that container A cannot talk to container B.
version: '2'
services:
rocketchat:
image: myimage
environment:
- MONGO_URL=mongodb://mongo:27017/dbname
depends_on:
- mongo
ports:
- 3000:3000
network_mode: host
mongo:
image: mongo:3.2
ports:
- 27017:27017
For each compose file docker-compose creates a network so in this case, should I manually assign the containers to a dedicated network as well? Or is there any workaround to access both the networks?
try to add links :
version: '2'
services:
rocketchat:
image: myimage
environment:
- MONGO_URL=mongodb://mongo:27017/dbname
depends_on:
- mongo
ports:
- 3000:3000
links:
- mongo
#network_mode: host
mongo:
image: mongo:3.2
ports:
- 27017:27017
and you do not need network_mode: host if you use the links
EDIT - Other solution:
version: '2'
services:
rocketchat:
image: myimage
environment:
- MONGO_URL=mongodb://localhost:27017/dbname
depends_on:
- mongo
ports:
- 3000:3000
network_mode: host
mongo:
image: mongo:3.2
ports:
- 27017:27017
network_mode: host
