Build

Prerequisites

• pyenv
• docker
• awscli

Build commands

pyenv virtualenv 3.7.5 cloudwatch-pod-alerts-operator
pyenv activate cloudwatch-pod-alerts-operator
pip -r requirements.txt
make

This will create a docker image with the application in it and upload it to ECR. Push the image into your repository of choice.

Install the CRD

The current CRD supports kubernetes <= 1.15.

kubectl apply -f crd-v1beta1.yaml

Setup RBAC

Setup roles and service account with needed permissions for the operator

kubectl apply -f rbac.yaml

Deploy the operator

Edit the deployment yaml and change the repository where the image is located

kubectl apply -f deployment.yaml

Test

Local testing

You can test the operator without craeting a container and deploying it in kubernetes. In order for this to work you need to uncommend lines 13-15 from src/handler.py Make sure you export AWS_PROFILE, AWS_DEFAULT_REGION and choose your kubernetes context before that.

kopf run src/handler.py

Create example alarm

Edit the example and replace the topics, namespace and cluster name

kubectl apply -f alarm.yaml

For your examples to work, the container needs to have IAM policy that allows it to access cloudwatchlogs assigned ot it

TODO

• Introduce parameters for cluster and region (currently region is hardcoded to us-west-2 for the creation of the cloudwatch alerts)
• Introduce a better kubernetes login mechanism to remove the need to uncomment the client authentication for local testing
