Docker Stack Deploy issue: ContainerSpec: image reference must be provided

[danielkhalilov]

Steps:
-Downloaded the latest unstable zenbot published today including Docker hotfixes (1/6/2018 22:00 EST)
-Ran "docker-compose build". Here are my images

zenbotunstable_server   latest              e27e89891907        23 minutes ago      894MB
node                    8                   b87c2ad8344d        3 days ago          676MB
mongo                   latest              1200574c8af9        10 days ago         366MB
mrvautin/adminmongo     latest              352119f77853        3 weeks ago         127MB

-Ran "sudo docker-compose up"
-Ran "docker stack deploy --compose-file docker-compose.yml zenbotunstable"

Here is the error:
Creating network zenbotunstable_default
Creating service zenbotunstable_mongodb
Creating service zenbotunstable_adminmongo
Creating service zenbotunstable_server
failed to create service zenbotunstable_server: Error response from daemon: rpc error: code = InvalidArgument desc = ContainerSpec: image reference must be provided

Seems like this error means that the image references may not be correct. however, the docker-compose.yml file reads mongo:latest and mrvautin/adminmongo, which matches my images.

Despite the above error, three containers were created (seen by running "docker ps")

(Not sure if Dockerfile is related to this, but when opening Dockerfile, this is what appears:)

I do not have much experience with Docker and struggling with cloud deployment. Is the above error an issue or should I proceed with deploying my containers as is?

[Shawn8901]

What do you mean by opening the docker file? With an editor or a shell?
The Dockerfile describes what docker has to do (to set the container up) and is no shell script!

About the other point i am not able to help you, because i have no experience with dockers stack deployment

The error pops up when you have a docker-compose.yml not specifying an image, we are however:
https://github.com/DeviaVir/zenbot/blob/unstable/docker-compose.yml#L6

so I'm not sure how to help you further.

[danielkhalilov]

Thank you very much @DeviaVir , worked like a charm. The docker-compose.yml i had was missing the Image image: deviavir/zenbot:unstable specified under Server: for whatever reason. This issue can be closed.
