Setting up Java SDK as Lambda Container Image
Docker Image Integration
docker pull thundraio/thundra-lambda-container-base-java8:LATEST
- Add Thundra base image as parent
FROM thundraio/thundra-lambda-container-base-java8:LATEST
- (Optional) Add following line to your Dockerfile if you want use a different version of the Thundra agent instead of the one coming with the base image.
RUN /opt/thundra/thundra-version-updater.sh <version>
The latest available version you can use to replace the
<version> parameter
- Make sure your function code is added to the task directory of your docker image and handler is set as the first argument of CMD
# your function code path
ARG FUNCTION_CODE_PATH="target/sample-app.jar"
# task directory
ARG TASK_DIR="/var/task"
# create task directory
RUN mkdir -p ${TASK_DIR}
# copy your function code to the task directory
COPY ${FUNCTION_CODE_PATH} ${TASK_DIR}
# Set the CMD to your handler
CMD ["io.thundra.container.sample.Handler"]
You can set your handler also by parameter overriding outside of the Dockerfile or setting it as the value of Lamba environment variable
THUNDRA_AGENT_LAMBDA_HANDLERAn example DockerFile:
FROM thundraio/thundra-lambda-container-base-java8:LATEST
RUN /opt/thundra/thundra-version-updater.sh 2.6.16
# your function code path
ARG FUNCTION_CODE_PATH="target/sample-app.jar"
# task directory
ARG TASK_DIR="/var/task"
# create task directory
RUN mkdir -p ${TASK_DIR}
# copy your function code to the task directory
COPY ${FUNCTION_CODE_PATH} ${TASK_DIR}
# Set the CMD to your handler
CMD ["io.thundra.container.sample.Handler"]
Step 3: Build your container image
docker build -t <image-name>
Step 4: Locally test your container image
- Run your Lambda application locally
docker run -p 9000:8080 <image name>
- Invoke your local application
curl -XPOST "http://localhost:9000/2015-03-31/functions/function/invocations" -d '{}'Step 3: Invoke Your Deployed Function
You should see your function’s expected response as the output of this request. You can also see the invocation logs on the console you run the Docker image.
Step 4: Push the container image to ECR and deploy it to your Lambda function
Step 5: Configure your function
Set the
THUNDRA_APIKEY environment variable to the API key value you got from the Thundra Console.
