We have ansible configured to deploy our various applications on IIS environment. I am trying to create a docker image of deployed applications so that I can just start up containers as we need for testing and otherwise.
I am planning to build on the Windows IIS image, start the container on azure, run our ansible to install everything on the server, then save the image on container.
I cannot find any documentation on how I can docker commit the container image into our private azure container registry.
Is it possible?
If you have an existing Docker registry in azure you should be able to use the az acr login --name myregistry command to authenticate to it https://learn.microsoft.com/en-us/azure/container-registry/container-registry-get-started-docker-cli. Make sure you have a registry created for the container image you want to push up.
Next, you can run the container in azure and do all the installation you want. SSH or RDP into the instance in Azure that is running this container. Now run docker ps and find the container id for the correct container. Next, use docker commit <container id> myregistry.azurecr.io/samples/nginx.
Then, just docker push myregistry.azurecr.io/samples/nginx
Also not sure what your use case is, but starting a container in order to modify and commit it in that way seems like an atypical use case for Docker since the build isn't reproducible via the Dockerfile. Looks like there are ways to replace Dockerfiles using Ansible playbooks with something like ansible-containers https://docs.ansible.com/ansible-container/ so you might want to take a look at that(I've never used this tool).
