I had the pleasure of presenting at SPTechCon in Boston today. It was a fun talk with a great audience.

As promised here is my Postman collection and slides:

Disabling TLS 1.0 on Windows 10

I’m setting up a new PC and as usual I’m installing PoshGit from Chocolatey. This time it failed trying to download the zip file. Turns out that GitHub has disabled TLS 1.0 connections which Windows 10 still ships with enabled.

The documentation on how to disable this this is reasonably good: https://docs.microsoft.com/en-us/windows-server/security/tls/tls-registry-settings#tls-10

It is a small edit to the registry, just create the keys to denote if you’re disabling the Client or Server TLS 1.0 protocol, or use the DisabledByDefault option for a little flexiblity, which is what I used.

Frankly I’m a bit surprised that this isn’t the default setting when you install Windows but I suspect that it causes few headaches for the average user.

North American Collaboration Summit presentation and samples

Last week I was in Branson, Missouri to present at the North American Collaboration Summit, a great conference which has grown out of the strong community that exists because of the SharePoint Saturday movement.

I talked about building chat bots, some of the considerations around making your bots not suck and gave a couple of demos at opposing ends of the spectrum, at the simple end I showed using QnA Maker to make an FAQ bot while at the complex end I demoed the ability to authenticate with BotAuth, integrate with Azure Functions, and the Microsoft Graph.

I’ve put the base code for both the Bot and the supporting Azure Functions up on GitHub for you to look at. I’m going to keep iterating on this code and making it suck less.

Microsoft Graph Community Call Recording

The Microsoft Graph team are awesome. Not only are they providing the Microsoft Graph but they are also really responsive and great to work with. Now they are looking to spread their love even further with a monthly community call.

If you missed the first call on December 5th, don’t worry, the recording and slides are now available. The next call is scheduled for January 2nd 2018, so start your year right with a dose of love from the Microsoft Graph team.

Docker on Windows – Angular Development

I’ve been on a bit of a Docker kick lately. Mostly to help my team reduce the time it takes to get up and running on a project. The end goal here being that, where possible, we’ll have containerized development and deployment environments.

A lot of this drive has come from needing to pick up a few older projects and encountering a number of issues getting these projects up and running. Some of these projects needed older versions of node, grunt or gulp installed to work correctly. Had the development environments for these projects been properly containerized a lot of the issues encountered could have been mitigated

As we’re using Angular and @angular/cli for a few of our front-end projects I’ve started there.

There are a number of public images available on Docker Hub that can provide a containerized runtime for you toolchain. I’ll use the teracy/angular-cli image in my examples here as it’s pretty well supported, allows for running tests, and is kept up to date by it’s maintainer.

In this post I’ll walk through getting a containerized dev environment set up and a few changes that you will need to make to your Angular project to have it run well under this arrangement.

Spin up your container

First of all make a new directory on the command line, move into and spin up your container…

mkdir my-new-app
cd my-new-app
docker run -it --rm -p 4200:4200 -p 49153:49153 -v ${pwd}:/my-new-app teracy/angular-cli /bin/bash

Assuming that you don’t already have the teracy/angular-cli image already this will pull down the image and launch a new container for you. This command also mounts the directory on your host machine in which you want to store your source code in the file system of the container as /my-new-app.

Next we’ll use the @angular/cli tools to spin up an new Angular project.

Scaffold your Angular App

ng new my-new-app –-skip-install
cd my-new-app
npm install

For some reason the npm install step in ng new always fails for me, so this sequence dodges that issue. That will take a little while as it pulls down all the necessary node modules from npm. Let’s take advantage of this time to make some changes.

Make ng serve work as expected

  • Open the my-new-app using your editor of choice from the host machine.
  • Open the package.json file
  • Change the start entry in the scripts object to read
    ng serve –host –poll 2000

This change binds the dev web server to listen to all requests on the default port (4200) and ensures that file changes made from the host machine are detected from the container for the purposes of automatic rebuilds.

Inside the container run up the development server by running this command:

npm start

From your host machine you can now go to http://localhost:4200 and you’ll see the skeleton app served to your browser. If you make changes to the code you’ll see a rebuild triggered when you save your changes.

All good so far. If this is all your want to do then you can even use my extremely light weight image gavinbarron/ng-cli-alpine.

Configure for running tests

However if you want to run tests then there’s still a little more to do and my image won’t meet your needs. Let’s get the tests running successfully.

Open the karma.conf.js file and add the section below after the browsers entry:

customLaunchers: { 
    Chrome_no_sandbox: {
        base: 'Chrome',
        flags: ['--no-sandbox']

Save all your changes and run in the container (Use Ctrl + C to stop the web server if you need to):

ng test --browsers Chrome_no_sandbox


I’ve seen you how easy it is to get a development environment for Angular up an running in a Docker container. You could take this further with docker-compose and a .yaml file as outlined in this great post that helped me get up and running: http://blog.teracy.com/2016/09/22/how-to-develop-angular-2-applications-easily-with-docker-and-angular-cli/

Docker on Windows – Network Issues

Recently after updating to version I noticed some network related issues while attempting to install new npm packages and interact with Docker Hub.

Attempting to search on Docker Hub would reliably fail

docker search dotnet
Error response from daemon: Get https://index.docker.io/v1/search?q=dotnet&=25: dial tcp: lookup index.docker.io on read udp> i/o timeout

Turns out the fix was remarkably simple, instead of using the Automatic DNS Server switching to a fixed DNS Server resolved the issue:

docker network settings

Docker on Windows – Mounting Volumes

If your using Docker on Windows and looking to share folders between your host machine and your running containers you’ll likely want to us the –v flag to mount a volume like this:

docker run –it --rm –v /d/some/folder/path:/app –w /app node /bin/bash

Luckily the error message is nice and helpful:

C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: C: drive is not shared. Please share it in Docker for Windows Settings. See 'C:\Program Files\Docker\Docker\Resources\bin\docker.exe run --help'.

The fix is simple:

  • Open up the system tray and find the whale, right click on it and select Settings…
  • Choose the Shared Drives tab on the left.
  • Check all of the drives that you would like to make available to Docker.
  • Then you will need to provide a username and password which Docker will then use to access files the files on the host machine, so take care here if you have funky file permissions.

So if you’re like me and using Waldek’s spfx container you can now edit the code from your host while the toolchain executes in the container.
There’s one small tip I have to you folks out there you can use ${PWD} in PowerShell to reference the directory in which you are running your command. so assuming that you are in the root folder of your spfx project it looks like this:

docker run -h spfx -it --rm --name spfx-helloworld -v ${PWD}:/usr/app/spfx -p 5432:5432 -p 4321:4321 -p 35729:35729 waldekm/spfx

Update: There’s also a more cryptic, and slightly misleading, message you might encounter if you use an account with an expiring password, like say, your domain account and you change the password…

C:\Program Files\Docker\Docker\Resources\bin\docker.exe: error during connect: 
Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.26/containers/create?name=ng-cli-test: open //./pipe/docker_engine: 
Access is denied. In the default daemon configuration on Windows, the docker client must be run elevated to connect. 
This error may also indicate that the docker daemon is not running..
See 'C:\Program Files\Docker\Docker\Resources\bin\docker.exe run --help'.
