drone-lambda

Deploying Lambda code with drone CI to an existing function. The plugin automatically deployes a serverless function to AWS Lambda from a zip file located in an S3 bucket. This plugin does not handle creating or uploading the zip file.

Usage

There are three ways to send notification.

Usage from binary

Update lambda function from zip file.

$ drone-lambda --region ap-southeast-1 \
  --access-key xxxx \
  --secret-key xxxx \
  --function-name upload-s3 \
  --zip-file deployment.zip

Update lambda function from s3 object.

$ drone-lambda --region ap-southeast-1 \
  --access-key xxxx \
  --secret-key xxxx \
  --function-name upload-s3 \
  --s3-bucket some-bucket \
  --s3-key lambda-dir/lambda-project-${DRONE_BUILD_NUMBER}.zip

Usage from docker

Update lambda function from zip file.

docker run --rm \
  -e AWS_ACCESS_KEY_ID=xxxxxxx \
  -e AWS_SECRET_ACCESS_KEY=xxxxxxx \
  -e FUNCTION_NAME=upload-s3 \
  -e ZIP_FILE=deployment.zip \
  -v $(pwd):$(pwd) \
  -w $(pwd) \
  appleboy/drone-lambda

Update lambda function from s3 object.

docker run --rm \
  -e AWS_ACCESS_KEY_ID=xxxxxxx \
  -e AWS_SECRET_ACCESS_KEY=xxxxxxx \
  -e FUNCTION_NAME=upload-s3 \
  -e S3_BUCKET=some-bucket \
  -e S3_KEY=lambda-project.zip \
  appleboy/drone-lambda

Usage from drone ci

Update lambda function, execute from the working directory:

docker run --rm \
  -e AWS_ACCESS_KEY_ID=xxxxxxx \
  -e AWS_SECRET_ACCESS_KEY=xxxxxxx \
  -e FUNCTION_NAME=upload-s3 \

AWS Policy

Add the following AWS policy if you want to integrate with CI/CD tools like Jenkins, GitLab Ci or Drone. Your function needs permission to upload trace data to X-Ray. When you activate tracing in the Lambda console, Lambda adds the required permissions to your function's execution role. Otherwise, add the AWSXRayDaemonWriteAccess policy to the execution role.
