This folder has sample apps configured for the integration tests +under sample apps in languages that support centralized sampling. As of now the languages +supported are Java and Go. To run these tests, first start up the collector, then +start up the chosen sample app, then start running the tests. + +## Run Locally + +### Set up collector +To run locally first set up the collector with the correct configuration. +It is possible that this is already done. Available ADOT Collector releases can be found here +[aws-otel-collector](https://github.com/aws-observability/aws-otel-collector/releases). +Make sure that the collector config is configured to work with a local x-ray listener pointed +to port 2000 and the docker run command exposes port 2000. Set up the ADOT collector with the +example-collector-config file. Clone the ADOT Collector repo and start the Collector with commands. +```shell + cd aws-otel-collector +``` +```shell + docker run --rm -p 2000:2000 -p 55680:55680 -p 8889:8888 \ + -e AWS_REGION=us-west-2 \ + -e AWS_PROFILE=default \ + -v ~/.aws:/root/.aws \ + -v "${PWD}/examples/docker/config-test.yaml":/otel-local-config.yaml \ + --name awscollector public.ecr.aws/aws-observability/aws-otel-collector:latest \ + --config otel-local-config.yaml; +``` + +### Start up sample app +Start up the sample app of your choice in the sample apps folder. The sample apps exist in the sample-apps folder. +Each sample app will have a readMe on how to run it. If adding a sample-app to use for the integration tests see +[Sample-app-requirements](https://docs.google.com/document/d/1nu6XwYKe8h3EZ6upCQqf83hI9gQ-yg5WXlxHRjJ7BCg/edit?usp=sharing) +. The sample apps were manually instrumented for X-Ray Remote Sampling, for more context see +[here](https://aws-otel.github.io/docs/getting-started/java-sdk/trace-auto-instr#using-x-ray-remote-sampling) + +### Start integration tests +Run this command in the directory `centralized-sampling-tests` once the Collector +and sample app are up and running. Ensure that the AWS account being used on your local account has no +pre-existing sample rules in it or the tests will fail. +```shell +./gradlew :integration-tests:run +``` + +### Github Actions +The tests will run automatically on PRs for changes that involve the centralized-sampling-tests folder. +It is also possible to run the tests manually as a GitHub action. To do this, you will need to make a fork +of the repository. From your fork, add a GitHub secret AWS_CENTRALIZED_SAMPLING_ROLE and add an AWS Dev +account with permissions to AWS XRay and GitHub setup. +Example: +```shell +AWS_CENTRALIZED_SAMPLING_ROLE: arn:aws:iam::123456789012:role/S3Access +``` +See [Setup AWS GitHub](https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/configuring-openid-connect-in-amazon-web-services) +for more information. Once the secret is added go to your forks actions, select the Centralized Sampling Integration Tests workflow and +click the Run workflow button. diff --git a/centralized-sampling-tests/build.gradle
