Testing

You will need an AWS account, a kubernetes cluster (running locally is fine) and python

Container image build

This assumes a target docker architecture of linux/arm64 (typically for OS X)

1. CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -o bin/controller ./cmd/controller/
2. docker build -f Dockerfile.local -t lambda-controller:local .

Kubernetes setup

Create a temporary credentials file in ~/.aws.temporary.credss that you don't mind using with ack-controller

[temp-profile]
aws_access_key_id=<access key>
aws_secret_access_key=<secret key>
aws_session_token=<session token>

1. kubectl create namespace ack-system
2. `kubectl create secret generic aws-credentials --from-file=credentials=$HOME/.aws.temporary.creds -n ack-system

3. helm install ack-lambda-controller ./helm \
     --namespace ack-system \
     --set image.repository=lambda-controller \
     --set image.tag=local \
     --set aws.region=ap-southeast-2 \
     --set aws.credentials.secretName=aws-credentials \
     --set aws.credentials.secretKey=credentials \
     --set aws.credentials.profile=temp-profile \
     --set installScope=cluster \
     --set leaderElection.enabled=false
   

Python set-up

In test/e2e:

1. Create a virtual environment python -m venv venv
2. Activate the virtual environment source venv/bin/activate
3. Install testing requirements pip install -r requirements.txt

AWS setup

In test/e2e:

1. Run AWS_PROFILE=my-profile ./setup.sh --pickle (or run setup.sh and then pickle.sh)

Setup the docker test image used by the lambda

In test/e2e/resources/lambda_function:

1. AWS_PROFILE=my-profile aws ecr create-repository --repository-name ack-e2e-testing-lambda-controller
2. Run AWS_PROFILE=my-profile make

3. repo=$(AWS_PROFILE=my-profile aws ecr describe-repositories --repository-names ack-e2e-testing-lambda-controller --query 'repositories[].repositoryUri' --output text)
   AWS_PROFILE=my-profile aws ecr get-login-password | docker login --password-stdin -u "${repo%/*}"
   docker push ${repo}:v1
   

4. Run zip main.zip main.py and zip updated_main.zip updated_main.py

Run the test suite

In test/e2e:

1. Run AWS_PROFILE=my-profile pytest

Clean up

In test/e2e:

1. Run AWS_PROFILE=my-profile ./teardown.sh
