Publish your container

In this lab you will learn how to manually push your container into a docker registry on Azure. Later on we will start using the DevOps pipeline to do so but for now this is manual.

Preparation

1. Login to Azure.

2. Create a docker registry.

3. Click on the newly created registry and go to Settings -> Access keys in the left navigation.

4. Note the parameters you will need to access the registry.

Login and push

1. Login to the docker registry:

   docker login -u <azure registry user> <azure registry host>
   

   You will be asked for the password interactively. docker will prevent you from using the -p parameter for security reasons.

2. Tag your image appropriately. To be able to push to that registry, your image must be tagged using the following pattern: <registryname>/<image>:<version>. While you can omit the version, the registry name and image name are mandatory.

   docker tag demoapp <registryname>/demoapp
   

3. You can now double-check with docker images. To to finally upload your image to the registy, use:

   docker push <registryname>/demoapp
   

   The output should be similar to this:

   $ docker push <registryname>.azurecr.io/demoapp
   The push refers to repository [<registryname>.azurecr.io/demoapp]
