If you have already created a Docker Compose stack and you are trying to start/restart the containers, you may face Docker error: Cannot start service ..: network $network-id not found error. Here I will quickly show you some working scenarios on how to fix it.
Prerequisites
- Docker
- Docker Compose
Solution
Step 1. First, check docker-compose.yml file for any network dependencies.
version: '3'
services:
...
networks:
default:
driver: bridge
db:
driver: bridge
elk:
external:
name: elastic-search
Here in the example above you can see that we have an external network that is linked to another service. You will have to check if the ELK stack is started and that network is created already. If not, you should create it.
Step 2. If step 1 is not your case, next you can check if there are some old container instances that were not removed.
docker container ls -a
If you spot some old containers that you are not using you can remove them with:
docker container rm $container_id
docker container rm $container_id
Step 3. If you’re still getting the same error the final step is to shut down the containers, remove them all and restart the Docker daemon.
Step 3.1. Shut down the Docker Compose containers:
docker-compose down
Step 3.2. Remove all containers:
docker rm $(docker ps -qa)
Or, use:
docker system prune
Step 3.3. Restart the Docker daemon:
systemctl restart docker.service
These steps will help you to re-create the networks and run the containers without network issues.
