The Current Status of Kubernetes-powered
Docker for Mac Platform

2. Kubernetes powered Docker for Mac 17.12 GA Release
[Current Status]
- Experimental K8s is only available under Docker for Mac 17.12 CE Final Edge Release.
[Updated - 1/6/2018]
- Kubernetes powered D4M is not available under Docker for Mac 17.12 CE Final Stable
Release [ Updated – 1/6/2018]
- Experimental K8s is not yet available under Docker for Windows 17.12 GA Edge or
Stable Release.[Updated – 1/5/2018]
- Experimental K8s is not yet available for Linux Platform.[ Updated – 1/4/2018]
- K8s powered Docker for Windows is slated to come by February 2018. [ Updated –
1/6/2018]
- D4M 17.12 CE Edge includes a standalone Kubernetes server & client as well as Docker
CLI Integration.
- The Kubernetes server runs within a Docker container on your Mac, and is only for local
testing

3. Kubernetes powered Docker for Mac 17.12 GA Release
[Current Status]
- The Kubernetes server runs locally within your Docker instance, is not configurable,
and is a single-node cluster
- If you independently installed the Kubernetes CLI, kubectl, make sure that it is pointing
to docker-for-desktop and not some other context such as minikube or a GKE cluster.
Run: kubectl config use-context docker-for-desktop. If you experience conflicts with an
existing kubectl installation, remove /usr/local/bin/kubectl
- The Docker for Mac Kubernetes integration provides the Kubernetes CLI command
at /usr/local/bin/kubectl. No need to install kubectl. IT COMES OUT-OF-THE-BOX.
- If you already have a Kubernetes YAML file, you can deploy it using
the kubectl command.
- Use the DOCKER_ORCHESTRATOR variable to override the default orchestrator for a
given terminal session or a single Docker command

4. Kubernetes powered Docker for Mac 17.12 GA Release
[Important Points]
• Future Release of Docker Platform will include both orchestration options available –
Kubernetes and Swarm
• Swarm CLI will be used for Cluster Management while for orchestration you have a choice
of Kubernetes & Swarm
• Full Kubernetes API is exposed in the stack, hence support for overall Kubernetes
Ecosystem is possible.
• Docker Stack Deploy will be able to target both of Swarm or Kubernetes.
• Kubernetes is recommended for the production environment
• Running both Swarm & Kubernetes is not recommended for the production environment.
• AND by now, you must be convinced – “SWARM MODE CLI is NOT GOING ANYWHERE”

5. Kubernetes powered Docker for Mac 17.12 GA Release
Why is Docker making this announcement?
Ask from community & customer –
- To have both Swarm and K8s available for the pockets within their organization that
are using it
- TO make K8s easier to manage
- For a Docker Dev to Ops experience with K8s
- For advanced capabilities of Docker EE around the secure software supply chain, HA
and automation for K8s
- To make K8s management available across Windows, multiple Linux distros & Cloud
