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.

Docker

Build the docker image with the following commands:

make docker

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.
