apart from following Drew’s advice, could you please send me the /etc/hosts from the host, output of `docker ps` and also could you enter the deployments container and print the environment with something like that:

```bash
docker exec -it `docker ps | grep deployments | awk '{print($1);}'` /bin/bash -c "set"

```
