How to try out the experimental windows 2016 support in the Rancher 1.3.0 release candidate?

Introduction

Yesterday Rancher commented on my github request for windows support ;

Tested with rancher-server version – v1.3.0-rc1 with catalog “library” set to vnext branch in https://github.com/rancher/rancher-catalog

Able to add “Windows Server 2016 Standard Evaluation” hosts successfully to rancher environment with orchestration set to “windows”.

Able to launch containers in “nat” network and “transparent” network.

@kvaes , Windows 2016 support will be available as experimental feature in rancher-server 1.3.0 release.

Great news! Let’s take it out for a spin… 😀

 

Rancher Host

Installing the host(s) is the same as any other time…  Though the host will still be a Linux machine off course ;

sudo docker run -d –restart=unless-stopped -p 8080:8080 rancher/server:v1.3.0-rc1

Though notice that I specified the v1.3.0-rc1 tag… And let the system do its magic!

(Update : For the stable, release you can omit the -rc1 part!)

Note ; Be aware that this is an early release candidate. Do not use this for your production! There is for instance a bug with the GUI, where the “Auto”-theme is malfunctioning. So switch to light or dark to get that one fixed. 😉

Using Visual Studio Team Services & Rancher for continuous deployment for your docker containers

Introduction

Today I’m going to show you how you can leverage the combination of Visual Studio Team Services & Rancher to kickstart your continuous deployment of your docker containers. So every time we update our containers, we want a smooth upgrade process on our container setup. What do you think? Let’s see what this can look like?

 

The flow

The scenario of today will have the following flow ;

  • We’ll use a git(hub) repository to store our docker-compose & rancher-compose file that powers our solution.
  • Next up, we’ll be using VSTS as the orchestrator for your CI/CD-pipeline.
  • Rancher is our preferred container workflow / management tool, and we’ll be using the “rancher-compose” on our VSTS build agent.

Testdriving the Azure Container Registry Service with Rancher

Introduction

A few weeks ago there was an announcement that the Azure Container Registry has went into public preview. That is great to hear! So let’s test drive it today… We’re going to set up the registry in Azure. Push a container image into it. And pull/run it via rancher towards our cluster. (To do this, I basically followed a lot of the following guide.

 

Setting up the Azure Container Registry (ACR)

So start by searching for the “Container Registry” in the marketplace ;

Running the Powershell AzureRM module in a Linux Docker container

Introduction

Given my affinity towards containers & azure, it will not come as a surprise when I say I published a small container from which you can launch AzureRM commands!

 

Repositories

  • Docker Hub (build) : https://hub.docker.com/r/kvaes/docker-powershell-azure/
  • GitHub (source) : https://github.com/kvaes/docker-powershell-azure

 

Getting Started

First of all, we’ll launch the container ;

docker run -ti kvaes/docker-powershell-azure

2016-09-23-10_09_10-rootdocker02_

Next up you do the device login ;

Login-AzureRmAccount

2016-09-23-10_08_33-rootdocker02_

And check out which commands are available…

get-command *azure*”

2016-09-23-10_08_20-rootdocker02_
As you notice, the current preview release is quite limited in available commands. Expect more to be added over time off course!

 

TL;DR

  • Powershell on Linux works
  • The AzureRM module is in preview, and limited in commands
  • It all works inside a container too! 😀

Deploying OMS for Docker via Rancher

Introduction
Today we’ll be deploying Microsoft Operations Management Suite (OMS) for Docker via Rancher… Sound cool? It is! Basically we’re going to do the following guide and add Rancher to the twist.

For those unfamiliar with the Microsoft offering and more knowledgeable  in the OSS community. Imaging OMS as being the Microsoft counterpart of a typical ELK stack. The advantage is that it’s managed and that there are already a lot of integrations possible.

Behind the scenes : Creating a Microsoft SQL Server as a Windows / Docker Container

Introduction

This post is the first of a series in my journey to build a flexible / production ready MSSQL windows container. I thought this would have been a breeze with my experience on Docker for Linux, though I must admit running into multiple issues… This post will not provide you with a working container, as I’m still developing that one.

2016-07-06 14_23_15-kvaeschost01 - 104.45.23.120_3389 - Remote Desktop Connection

Once I deem it as production ready, it’ll be released to the community to be used freely. Though I want it to meet my personal quality standards, being that it should be stable and flexible enough to run in production mode.

 

Blueprint Braindump

For those who have been following me for a while (real life, twitter, yammer, linkedin, …); you probably know I’ve been preaching about MSSQL as a container for way too long. My personal vision was to have a MSSQL run in a container. The data should be located outside of the container, which would enable a (more/relative) easy path for the changes you want to implement.

kvaes-mssql-container-blueprint-docker-persistent-storage-identity-repository

So where volume mapping would be an option… I was also considering an integration with an external storage service. As an Azure fanatic, I (also) want to leverage the option of storing my data/temp files on Azure storage. This would provide my with total host independent storage persistence on Docker! For those who have been playing with Docker for a while, this is truly a powerful combination.

As a long term goal, I would like to see this running on a “serverless” platform. From what I have seen in the market, this is still an unreachable utopia/Walhalla at this point. So my current objective in that areas is to investigate the option of deploying this setup on a Service Fabric or to leverage the power of Rancher with Windows containers.

Integrating Azure Active Directory with Rancher

Introduction

Today we’ll be doing a post on how to integrate “Azure Active Directory” with my favorite docker orchestration tool “Rancher“. A few months back I issued a request towards the Rancher team (via Github) and it was added in the latest 1.1.0 release!

 

Authentication & Authorisation

So what can we do with it? The first thing I want to point out that in any identity process, there are two conceptual aspects;

  • Authentication ; Here you provide a way to prove that you are really you… This can be done via user/pass, certificates, … and so on.
  • Authorization ; Once your identity has been known, you can be granted with a given set of permissions (maybe grouped by role).

Why do I say this? It’s important to know that once you enable the AAD (Azure Active Directory) integration, this part will become responsible for the authentication part. Rancher UI (or Rancher Server) will remain responsible for the authorization part!

 

Identity Flow with the AAD integration

The following diagram will show you how the flow goes…
