Could not connect to database using connectionString: mongodb://root:example@mongo:27017/"

[chakrabortyanshu]

I am running docker-compose -f stack.yml up as mentioned in the hub.docker.com. It is not working for me.
The logs from both containers are available here.

Thanks in advance.

You might've tried connecting before it was fully initialized. But it started successfully here and is waiting for incoming connections https://github.com/chakrabortyanshu/Issues/blob/5a6b677c588bb6dd98d188e89b2b3bfa10824bd0/mongodb/mongo_log.log#L173-L175

Hi @wglambert
thank you for your response. Yes, the mongo is running fine as you have rightly pointed out. But mongo-express continues failing with the below log snippet. For some reason, the mongo-express is not able to find the URL mongodb://root:example@mongo:27017/. I am using the stack.yml from the link mongo docker hub example. Not sure what is going wrong?

FYI: I kept the dockers running for one hour complete. Later I restarted mongo-express but still the same result.

Any recommendation?

I just tried locally with docker-compose -f stack.yml up and while it recreated the mongo-express container multiple times (usually failing with a similar log error, but starting a new one with the restart: always), after a few times mongo was finally ready for connections and the next start of mongo-express succeeded.

Interesting to note that mine failed with ECONNREFUSED, but yours has MongoNetworkTimeoutError: connection timed out. It seems like docker internal networking is being blocked or something. Maybe you need to restart docker or the host itself? Or maybe extra iptables rules being applied before docker's rules?

Hi @yosifkit,
Thanks for your response.

Just to confirm that the containers are able to communicate, I executed the below commands.

• Confirmed that both the containers are running on the same network.

  anshuman@anshuman:~$ docker inspect -f '{{range $key, $value := .NetworkSettings.Networks}}{{$key}} {{end}}' mongo
  mongodb_mongodb_default 
  anshuman@anshuman:~$ docker inspect -f '{{range $key, $value := .NetworkSettings.Networks}}{{$key}} {{end}}' mongo-express
  mongodb_mongodb_default 
  

• Mongo-express is restarting frequently. But whenever it was available, I was able to ping the mongo container from the mongo-express container

   anshuman@anshuman:~$ docker exec mongo-express ping mongo -c2
   PING mongo (172.22.0.3): 56 data bytes
   64 bytes from 172.22.0.3: seq=0 ttl=64 time=0.078 ms
   64 bytes from 172.22.0.3: seq=1 ttl=64 time=0.141 ms
   
   --- mongo ping statistics ---
   2 packets transmitted, 2 packets received, 0% packet loss
   round-trip min/avg/max = 0.078/0.109/0.141 ms
  

• Pinged mongo's IP from the container mongo-express

  anshuman@anshuman:~$ docker inspect -f '{{.NetworkSettings.Networks.mongodb_mongodb_default.IPAddress}}' mongo-express
  172.22.0.2
  anshuman@anshuman:~$ docker inspect -f '{{.NetworkSettings.Networks.mongodb_mongodb_default.IPAddress}}' mongo
  172.22.0.3
  anshuman@anshuman:~$ docker exec mongo-express ping 172.22.0.3 -c2
   PING 172.22.0.3 (172.22.0.3): 56 data bytes
   64 bytes from 172.22.0.3: seq=0 ttl=64 time=0.101 ms
   64 bytes from 172.22.0.3: seq=1 ttl=64 time=0.157 ms
