Containers are isolated, but share OS and, where appropriate, bins/libraries

Docker offerings• Docker Daemon – Process that runs containers within• Docker CLI – Command line utility to interact with

docker apis• Docker Machine – API to create/manage Docker hosts• Docker Compose – API to orchestrate containerized

applications• Docker Swarm – Container Cluster running multiple

containers• Docker Registry – Registry to maintain Docker images

aka.ms/DockerToolsForVSCode

VSTS Docker Extension• Exposes build tasks• Build an image• Push an image to Docker

registry• Run Docker images in

container• Orchestrate Multi container

Docker application• Deploy to Azure Container

Servicehttps://marketplace.visualstudio.com/items?itemName=ms-vscs-rm.docker

Azure Container Service• Create a container hosting solution optimized for

Azure• Use popular open source, client-side tooling• Scale and orchestrate applications using DC/OS or

Docker Swarm• Migrate container workloads to and from Azure

without code changes• Manage container applications using familiar tools

Azure Container Registry (preview)

• Keep Your Images Private• Stored in Azure with your resources

• Network-Close• Deployed to your targets within the same data center• No ingress/egress fees or latency

• Azure Active Directory Integration• Manage registry access using AAD

• Familiar Open Source CLIs• docker login, pull, push

Azure CLI 2.0 (preview)• Cross platform CLI to

interact with Azure• Easy to create Azure

resources from command line
