Other OS

1. Get a Mac
2. See Above MacOS

Setting up IntelliJ

1. Install the IntelliJ Python plugin
2. Set up pyenv
   1. File -> Project Structure or CMD + ;
   2. SDKs -> + -> Add Python SDK -> Virtual Environment
   3. Select Existing Environment
   4. Choose ~/.pyenv/versions/echofish-aws-raw-to-zarr-lambda/bin/python
3. Set up Python Facet (not sure if this is required)
   1. File -> Project Structure or CMD + ;
   2. Facets -> + -> Python
   3. Set interpreter

Installing Dependencies

2. pip install --upgrade pip && pip install -r requirements_dev.txt

Maven

This project can use Apache Maven to easily build this project. However, this is not required, but recommended. Maven can be easily installed by downloading it from the Maven site or using sdkman.

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
