Build with Maven

After setting up your pyenv run: mvn clean install

DOTENV

export AWS_DEFAULT_PROFILE=echofish

Functional Testing

To run a functional test, developer will need to save the associated environment variables in .env for the lambda to use. The ACCESS_KEY and SECRET_ACCESS_KEY can be generated in IAM, users, rudy-dev, security credentials, access keys, create access key. Copy other values as needed from deployed CloudFormation Template.

export OUTPUT_BUCKET=rudy-dev-echofish-118234403147-echofish-dev-output
export TABLE_NAME=rudy-dev-echofish-EchoFish-File-Info
export OUTPUT_BUCKET_ACCESS_KEY="XXX"
export OUTPUT_BUCKET_SECRET_ACCESS_KEY="YYY"
export TOPIC_ARN="arn:aws:sns:us-west-2:118234403147:rudy-dev-echofish-processing-finished"

Deploying new CodePipeline via Cloudformation

Build project w 'mvn clean install', navigate to the 'target/codepipeline' directory. You will need to create a private ECR repo in us-east-1 w name of the project for builds to push to. Then:

aws --profile mggdev cloudformation create-stack --stack-name build-echofish-aws-raw-to-zarr-lambda-trunk --template-body file://codepipeline.yaml --capabilities CAPABILITY_IAM CAPABILITY_AUTO_EXPAND

Elastic Container Registry

Note that the main repository is built and curated in the mgg-dev account in us-west-2. The derived docker image is built and pushed to the echofish us-east-1 ECR. That image is then replicated to the echofish us-west-2 account. You will need to go to the echofish ECR -> Repositories -> [repo] -> Permissions and copy the values from an existing project (for both regions).

In the echofish aws account:

IAM -> Roles -> AWSServiceRoleForECRReplication

To Run Tests

python -m pytest
