Microscaling Engine

Our Microscaling Engine provides automation, resilience and efficiency for microservice architectures. You can use our Microscaling-in-a-Box site to experiment with microscaling. Or visit microscaling.com to find out more about our product and Microscaling Systems.

This project is no longer being developed. As an alternative we recommend you take a look at Keda.

Docker Image

Build

Build Status

Go 1.6 & 1.7

Microscaling Engine is under development, so we're not making any promises about forward compatibility, and we wouldn't advise running it on production machines yet. But if you're keen to get it into production we'd love to hear from you.

Schedulers

Microscaling Engine will integrate with all the popular container schedulers. Currently we support

  • Docker API
  • Marathon
  • Kubernetes

Support for more schedulers is coming soon. Let us know if there is a particular scheduler you wish us to support.

Metrics

Currently we support scaling a queue to maintain a target length. Support for more metrics is coming soon.

2 queue scaling algorithms are available.

  • SimpleQueue - scales containers up or down by one according to whether the queue is too long or too short.
  • Queue - uses control theory to prevent oscillation.

Queue Types

  • SQS - blog post with more details coming soon.
  • NSQ - see this blog post for more details.
  • Azure storage queues - this blog post describes using the Azure queue as the metric while running microscaled tasks on DC/OS.

Support for more message queues is coming soon. Let us know if there is a particular queue you wish us to integrate with.

Running

The easiest way to run Microscaling-in-a-box is to follow the instructions. The docker run command pulls the latest image of this code from Docker hub.

Running with label-based config

Get scaling parameters from your image metadata by configuring them with the following labels:

  • com.microscaling.is-scalable
  • com.microscaling.priority
  • com.microscaling.max-delta
  • com.microscaling.min-containers
  • com.microscaling.max-containers

Download the compose file and add the following environment variable to the environment settings for the microscaling image:

MSS_CONFIG=LABEL

Building from source

If you want to build and run your own version locally:

  • Clone this repo
  • Build your own version of the Docker image DOCKER_IMAGE=<your-image> make build
  • Specify -it <your-image> instead of -it microscaling/microscaling:latest on docker run so that it picks up your version of the image

License

What's the license on this?

Running Grunt

There is no .jshintrc file in the repository causing the default grunt task to fail. Looks like it was accidentally added it to the .gitignore

ImageLayers cannot find tags for public image

Hi,

I added this public repository yesterday:

https://hub.docker.com/r/pavel/howdy/

However, ImageLayers cannot find image tags.

Steps:

  1. Navigate to https://imagelayers.io/
  2. Click on "Search for images on the Docker Hub".
  3. Enter "pavel/howdy".

Outcome:

Request URL:https://imagelayers.io/registry/images/pavel/howdy/tags
Request Method:GET
Status Code:500 Internal Server Error
Remote Address:64.211.224.18:443

GET https://registry-1.docker.io/v1/repositories/pavel/howdy/tags returned 404

It seems like you are trying to use deprecated API.

wordpress image

When trying to view wordpress:latest image, I get an error:

"The following images could not be found: wordpress:latest "

Expand FROM to the right

This is a feature request.

It would be nice to see the FROM directives, for a given docker package, expanded to the right. So say i search on node:latest. I understand that all the FROM are automatically expanded downwards, but when doing this i don't see the structure of the packages. I'd like to see each package. One reason for this is because some packages will be security reviewed and certified for use. So from there and below, i don't need to review any further.

Maybe leave the FROM and create an action to expand it as needed by the user.

The badge is not updated on Github after Docker image update

For some reason the badge is not updated for new Docker image. I see only "question mark" icon and link to image takes me to some github cached location. Original image URL, provided by ImageLayers works just fine. It's a GitHub image cache issue, but you need to update header you return to GitHub to make him "purge" it's cache or not to cache at all.
Here is my project's README.md
