Prometheus Example

This is an example of creating a simple single node Prometheus setup. Note that this blueprint references an image created by the base image scripts at https://github.com/getcloudless/example-base-image, so this will fail unless you run that first.

Installation

You can clone this repo, and then install Cloudless and the other dependencies using pipenv:

$ git clone https://github.com/getcloudless/example-prometheus.git
$ cd example-prometheus
$ pipenv install
$ pipenv shell
$ which cldls

Usage

The file at blueprint.yml can be used in any service command:

cldls service create blueprint.yml

You can run the service's regression tests with:

cldls service-test run service_test_configuration.yml

Note that these are completely independent of what provider you're using, assuming you've already built the Base Image.

Workflow

The main value of the test framework is that it is focused on the workflow of actually developing a service. For example, if you want to deploy a service (and all its dependencies) that you can work on without running the full test, you can run:

cldls service-test deploy service_test_configuration.yml

This command saves the SSH keys locally and will display the SSH command that you need to run to log into the instance.

Now, say you want to actually check that the service is behaving as expected:

cldls service-test check service_test_configuration.yml

You can run this as many times as you want until it's working, as you are logged in. Finally, clean everything up with:

cldls service-test cleanup service_test_configuration.yml

You're done! The run step will run all these steps in order.
