By default parts of the Kubernetes ecosystem run as containers in a hidden namespace called system. One of the other key differences between Docker Swarm and Kubernetes is the support for namespaces. If you find that too verbose to type in then the Kubernetes community has a tool called kubectx that make that shorter. kubectl config use-context docker-for-desktop If you've ever installed minikube then you'll have to switch out of that context into the DfM context otherwise kubectl will hang. The support is then downloaded via a UI option and this can take several minutes. You currently need to be on the "edge" track of Docker CE in 17.12 or greater to get Kubernetes support.

Here are my first impressions through getting hold of the update, kicking the tyres with an application and seeing what the Docker "stack" integration is like. Let's move onto my first impressions of Kubernetes on Docker for Mac. To summarise the tooling there are pros and cons to each option. Use when: you need a local Kubernetes environment but don't mind if the Docker version is older.

Some features hard to access or not officially supported such as RBAC (role-based authentication control).

Docker version lags behind significantly (i.e.

Docker integration feels similar to docker-machine.

Kubernetes uses a significant amount of battery at idle.

Easy access to Kubernetes for local development.

Kubectl is now configured to use the cluster. Starting local Kubernetes v1.8.0 cluster. Its primary purpose is to create a single-node Kubernetes cluster which also includes a Docker host that can be used for development.Įxample output of starting up minikube on my Mac: $ minikube start Minikube has a very similar user-experience to docker-machine and also relies on boot2docker. Use when: it's available to you and you need Docker Swarm or Kubernetes support for local development.

#Docker for mac review windows 10#

Only available on Windows 10 Pro or Enterprise.

High CPU usage is reported by hyperkit resulting in low battery life.

DfM has had performance issues with shared volumes.

Can be started/stopped with a single click.

Configuration through UI for proxies / registries etc.

Command-line is automatically configured.

The initial release of DfM was through a limited beta and there was a big demand on Twitter for it. Docker for Mac/Windows or DfM was pitched as a "native" integration which meant it came with a UI and a menu-bar that was hugely popular.

The problem with Docker Machine was that it involved too many manual steps ( docker-machine env etc) and configuration sometimes needed to be regenerated for TLS. Or you're creating/managing a remote cloud cluster. Use when: you're on Windows 7 or Windows 10 Home or need a cluster of machines on your local computer.

Less "native" integration on Windows / Mac.

pluggable architecture - with plugins for major cloud providers / distros.

multiple Docker back-ends even on the same computer.

It could support multiple-concurrent Docker versions or hosts at the same time for clustering. Once the VM was running SSL certificates were generated and then the Docker client accessed the remote or local VM over TCP/IP. This also meant upgrading from one version to another was easy.

Docker Machine automated the setup of a virtual machine on a local or remote environment and made use of standard ISO images ( boot2docker) plus a writeable disk area. Docker Machineĭocker Machine was the next step in the tooling evolution. Use when: none of the following options work for you. Sometimes people also use vagrant from Hashicorp to provide a consistent CLI between VM host software.

They would need to install a Linux host manually and then set up shared folders. Here's a a brief history of developer tools and how they brought Linux containers to Mac and Windows users: Virtual machines - version 1īefore any of this tooling someone on a Mac or Linux computer who wanted to access Linux container would have needed to have installed a Virtual Machine host such as VirtualBox or VMWare Workstation/Player. This has been a journey and we didn't start day one with Kubernetes support in Docker for Mac, so let's look at the context:Ĭontainers (which normally means Linux containers) were not available on Windows or Mac when Docker began its story as a spin-out from DotCloud.

Docker) is a piece of software which has brought the benefits of containers to the people (democratisation) and made them extremely easy to use and valuable (commoditisation). Let's take a look at what this means, a brief history of developer tooling and then cover my first impressions as I kick the tyres.ĭocker CE (nee. I'm excited to say that Docker for Mac is now shipping with support for both Docker Swarm and Kubernetes built-in.
