Docker Containers on Azure VMSS

Question

Good day. I would like to deploy docker containers on Azure VMSS. What needs to happen is that I have 3 docker containers. I want a VM to have all three docker containers. When traffic expands, there will be multiple VMs having the same docker containers. However, at the moment, I am struggling with getting the containers on VMSS. I have created a "Modify custom data" script that is supposed to install docker and also pull the containers. However, when using "Serial Console", I can see that docker is not installed. For some reason, SSH is also not working, even though NSG has an inbound rule that allows SSH port 22 to be accessed. Is Azure VMSS able to have containers running on them? And if so, how can I achieve this scenario. I am using Container Registry, since that is where the docker images are uploaded.
