Why does Docker Compose lose communication between containers intermittently on Centos?

I’ve been using this docker compose configuration for a couple of years in production now, and it’s been fine until randomly crashing twice in the past week…

version: "3.7"
services:
  web:
    image: backend
    build: ..
    restart: unless-stopped
    expose:
      - 8000
    ports:
      - 9109:8000
    env_file:
      - &ENV_FILE ../.env
    depends_on:
      - db
      - worker
    volumes:
      - &MEDIA_VOLUME /srv/media/:/srv/media
      - &STATIC_VOLUME /srv/static/:/srv/static
      - &TMP_VOLUME /tmp/:/tmp/host/
    logging:
      driver: journald
      options:
        tag: docker-web
  worker:
    image: backend
    environment:
      - REMAP_SIGTERM=SIGQUIT
    command: /usr/bin/start-worker.sh
    restart: unless-stopped
    env_file:
      - *ENV_FILE
    depends_on:
      - db
      - redis
      - rabbitmq
    volumes:
      - *MEDIA_VOLUME
      - *STATIC_VOLUME
      - *TMP_VOLUME
    logging:
      driver: journald
      options:
        tag: docker-worker
  db:
    image: mdillon/postgis:11
    shm_size: '256m'
    restart: unless-stopped
    env_file:
      - *ENV_FILE
    volumes:
      - /var/docker-postgres/:/var/lib/postgresql/data/
      - *TMP_VOLUME
    logging:
      driver: journald
      options:
        tag: docker-db
  memcached:
    container_name: memcached
    image: memcached:latest
    ports:
        - "11211:11211"
  rabbitmq:
    image: rabbitmq:management
    ports:
      - 5672:5672
      - 15672:15672
  redis:
    image: redis:latest
    expose:
      - 6379

Suddenly last week I started seeing errors from the web process:

could not translate host name "db" to address: Name or service not known
Error -2 connecting to redis:6379. Name or service not known.

When I checked on the processes they all seemed to be running:

$ docker-compose ps
      Name                     Command               State                Ports

                                                             15691/tcp, 15692/tcp, 25672/tcp,
                                                             4369/tcp, 5671/tcp, 0.0.0.0:5672
                                                             ->5672/tcp,:::5672->5672/tcp

                                                             8000/tcp                        
docker_worker_1     /usr/bin/start-worker.sh         Up                                      
memcached           docker-entrypoint.sh memcached   Up      0.0.0.0:11211->11211/tcp,:::1121
                                                             1->11211/tcp

However it seems the containers were unable to communicate as these errors continued indefinitely until I stopped the containers and started them again. Then everything was fine, for a few days, until it suddenly happened again without probable cause…

Any ideas what might be happening?!

May 21 07:06:23 my-hostname systemd: Started Docker Application Container Engine.
# now failing

So I think the trigger for the issue is the automatic update of docker packages by yum in CentOS, and the restarting of the Docker Application Container Engine, after which the networking breaks down. there are running containers, updated network configuration will not take affect sounds particularly suspicious!

Aside from turning off automated yum updates, how can I ensure that the container networking won’t break in these situations?

Since containers are having issues talking to each other, one thing we can test is whether the DNS resolution working fine or not.

Check if DNS resolution is working correctly within the Docker network. You can try running a temporary container and test if DNS resolution works for the service names. For Eg:
```
docker run --rm -it --network=<your_network> alpine nslookup db
docker run --rm -it --network=<your_network> alpine nslookup redis
```
–> If you have any DNS caching mechanisms in place (e.g., DNS caching on the host machine or within the containers), ensure that they are not causing any conflicts or outdated information.

–> As a last resort Restarting Docker: If the issue persists and you cannot find any other causes, you can try restarting the Docker service itself. This may help resolve any potential networking or DNS-related issues.

–> It’s also worth mentioning that updating Docker Compose to the latest versions might help resolve any known issues or bugs. The docker-compose version you are using is docker-compose version 1.24.0, build 0aa59064

There have been so many new versions released after this. please check here for the latest versions
https://github.com/docker/compose/releases

I have been facing issues because of the low version of docker-compose used in my application. once upgraded to the latest one the was fixed. But the issue was not the exact same as you are facing.

I would not suggest any testing in the Prod environment but in parallel, you can update the docker-compose version and test in dev or qa to monitor for issues.

I would also suggest having a network set in the docker-compose file so that containers will be linked through the external network. I am not sure it can resolve this name resolution issue. But this is something you should be implementing in your services.

Hope this will help

I have written this as an answer, instead of comment, for text formatting reason.

Can you try to put following in /etc/resolv.conf ?
```
search localdomain
nameserver 127.0.0.11
options edns0 trust-ad ndots:0
```
which is I’ve got when I run your docker-compose.yml.

Also, check /etc/resolv.conf in all your containers.

Such issues when upgrading Docker daemon are expected. On upgrade, Docker daemon will shutdown – and existing containers will be restarted by default.

You can configure Docker Daemon to enable Live Restore. Edit or create etc/docker/daemon.json (default path for Docker daemon config on Linux) to specify:
```
{
  "live-restore": true
}
```
Note however it may not work for major upgrade (such as 23.x > 24.x) so you may want to configure automatic update accordingly.
