Portainer for Kubernetes – BETA

It is with great delight that I am able to announce the public BETA release of Portainer, with support for Kubernetes.

We have just pushed the images to Docker Hub, published the release notes, created all the backing documentation to support user feedback, and have completed our functional testing.

Portainer Update, March 2020..

Hi Portainer fans... time for a little update..

Sorry for the long delay between blog posts, but our little team has been kept quite busy building support for Kubernetes into Portainer, working on our next release, and extending our Edge Compute functionality.

Docker on Windows Platforms with Portainer – Known Issues

UPDATE as of 29th May, 2020

We have just updated our Windows 10 testing environments to Windows build 2004 (now GA) and Docker Desktop 2.3.0.3, and have re-run the failing tests below using Portainer 1.24.0 with the following results:

Issue 1: Continues as its unrelated to Windows Build or Docker Version
Issue 2: RESOLVED when using WSL2 back-end, but still fails when using HyperV back-end
Issue 3: Continues
Issue 4: Continues

So, in summary, Docker on Windows 10 is now far more reliable when using Linux Containers and WSL2. No known issues at all with this.

Docker News, and the continued Portainer Vision

If you are reading this post, i will assume by now that you have heard/read the news of Docker EE’s acquisition by Mirantis, and their eventual sun-setting of Swarm within the next 2 years.

It’s important to me to explain to our user community that this does not materially impact Portainer or our vision.

Deploying Portainer on a Windows 2016 or 2019 Swarm Cluster

By popular demand, i will quickly show you the process to get Portainer and the Portainer Agent running in a Docker Swarm environment atop Windows Server 2016 or 2019.

Deploying Portainer and the Portainer Agent to manage a Windows 2016 (1803) or Windows 2019 (1903) Swarm cluster is easy !

This procedure ONLY works if you are running Docker EE 19.03.5 or later, so if you are not, update before continuing.

How does the edge agent work

Now that the edge agent has been released, let me give a brief overview of how it works. Note that deep technical documentation will be made available in the agent repo on github in due course.

In standard deployments, the central Portainer instance and any endpoints it manages are assumed to be on the same network, that is, Portainer and the agents are able to seamlessly communicate to one another.

Portainer Edge Agent

With the adoption of containers continuing to accelerate, we are seeing deployments of the Docker engine extending beyond the server. Containers are making an appearance in everything from storage devices and Ethernet switches, though to IOT monitoring/control equipment.

Portainer + Kubernetes

We have been asked for over a year now what our "Kubernetes Strategy" is, and our answer has always been the same:

"Portainer's sole reason for being is to simplify container platform operations; when Kubernetes gets simplified, we will integrate it into Portainer".

Well, we have come to a point where we now believe that its impossible to simplify Kubernetes to a level where we can verbosely pass through and visualize its plethora of functions 1:1, akin to what Kubernetes' native dashboard does.
