Building Windows Docker Images and Uploading them to AWS Elastic Container Service

Prereqs

• Windows with Containers (Any Windows 10 install with the Anniversary update will do)
• Docker
• AWS CLI

Building the Image

In powershell, in the directory containing a Dockerfile.

docker build -t <nameOfImage>:latest -m 2GB .

this will take a while, so go grab a beer or 10... you deserve it..

After the build finishes, you can run and test the image by running:

docker run -it <nameOfImage>:latest

When you are satisfied the image is to your liking, simply exit the container.

Publishing the Image

First we need to tag the image. Your ecr uri can be found on the AWS Console for your ecr repostiory

docker tag <nameOfImage>:latest <your aws account number>.dkr.ecr.us-east-1.amazonaws.com/<repo name>/<nameOfImage>:latest

On windows, the next part is painful due to the way the credential store works. You need credentials for docker push to work. To do this you use the aws ecr get-login command. However, this doesn't work so.... you'll need to tweek it a bit.

aws ecr get-login > dumb_behavior.txt

Now open the dumb_behavior.txt file and change the https to http. Now copy the entire contents of the file and run it as a command in powershell.

Now finally, you should be able to publish the image:

docker push <yourAccountId>.dkr.ecr.us-east-1.amazonaws.com/<repo name>:<nameOfImage>:latest

Assuming all of that works, you should now be able to use the image for things like codebuild.
