Azure IOT edge error pulling docker image of custom nodeJS module

Question

Hi I'm making an Azure IOT edge Gateway and I’m trying to install à custom module on it but I have this error:

Error calling Create module serverModule: Could not create module serverModule caused by: No such image: MyDockerAzureContainerServer/serverModule:0.0.1-amd64) ....

but if I run

docker pull MyDockerAzureContainerServer/serverModule:0.0.1-amd64

it works!

BTW : I’m working on a winndows10 device running docker Linux containers

I really don’t get it thanks for any help.

(English is not my native language sorry)

are you using a private container registry (such as Azure Container Registry) or does your image reside in public Dockerhub? — silent
Do you have a registryCredentials in your deployment.json? docs.microsoft.com/en-us/azure/iot-edge/… — silent
Yes I do and I know they are good because in azure I can see the image — Ehanno.M
can you post your entire deplyomen.json? (removing all passwords etc) — silent

I finally manage to run it :

I configured my docker to run windows containers and I created a dockerfile.windows-amd64 on witch I run basic npm installations commands for windows.

Dockerfile.windows-amd64 :

FROM stefanscherer/node-windows:latest
RUN mkdir \app
WORKDIR /app

ONBUILD COPY package.json package.json
ONBUILD RUN npm install
ONBUILD RUN npm install {anny other specific dependencies} --production

ONBUILD COPY . .

CMD [ "node.cmd", "app.js" ]

once you have done that you need to add this file un the known platforms, to do so modify the module.json file of your projet and add the windows-amd64 line :

{
    "$schema-version": "0.0.1",
    "description": "",
    "image": {
        "repository": "{you're Server Name}.azurecr.io/{you're Module}",
        "tag": {
            "version": "0.0.1",
            "platforms": {
                "amd64": "./Dockerfile.amd64",
                "amd64.debug": "./Dockerfile.amd64.debug",
                "arm32v7": "./Dockerfile.arm32v7",
                "arm32v7.debug": "./Dockerfile.arm32v7.debug",
                "Windows-amd64": "./Dockerfile.windows-amd64"
            }
        },
        "buildOptions": []
    },
    "language": "javascript"
}

and finally you need to modify this line in the deployment.template.json :

[...]
 "modules": {
     "{you're Module}": {
         "version": "1.0",
         "type": "docker",
         "status": "running",
         "restartPolicy": "always",
         "settings": {
             "image": "${MODULES.{you're Module}.Windows-amd64}",
             "createOptions": {}
         }
     }
 }
[...]

And it should run fine.

Note that I Run now a NodeJS app on a Windows container on a Windows machine running docker Windows.

I leave this answer if it can help anyone feel free to contact me of you have any questions.
