Swarm service cant use local images [1.12.2]

Open Source Projects Swarm
1

i am running a server with debian jessie and docker 1.12.2 on it. when i build images locally i cant use them by creating a service. as far as i know, it should be the default to first check if the image is locally available?
struggling with this issue more than a day and have no plan how to get rid of it!

someone have a solution or an advise?

here some logs:

Did you find a solution? I have the same problem on 1.12.3. Using Ubuntu images, not Debian though.

In swarm-mode the manager does not share the local images with all the other nodes if the swarm cluster. So when you build your image on a node (let’s call it node-1), only this node have access to the image. And when you execute “docker service create”, you do not know on which node the container(s) corresponding to the service will be started (except if you use constraints), so if this is on a different node, it cannot access to the image you built because this image only exists on node-1.
To achieve this, you must use a registry (either Dockerhub or a private registry) and push your image on it after the build. Then, if you specify the complete name for the image (/<image_name>), the creation of the service will cause the image to be pulled from the registry to the node(s) that must receive the container(s) corresponding to the service.

@yogeek you are right, but if i manually build it on the second node it should therefore check if a local version of it is available? i understand the issue but i dont understand why it does not work that way. i assume that if i create a service it will use some build-id of the image rather than the actual name (tag) of it- this will of course differ at the different nodes and would cause this behavior. but i am not sure if it is the right solution.

@srzjulio unfortunately not, but the solution from yogeek will work of course.

Yes, the image can be shared via private registry. But, I have another question, can the cached image be shared across the host. That is, in the cluster, the images are pulled and cached on one host then shared by other host. Could it be solved by shared storage?
