Instana distributed tracing task on lightweight container with cloud native build packs (Ahead of Time)
If you're already familiar with Spring Boot container images support, this is the easiest way to get started. Docker should be installed and configured on your machine prior to creating the image.
To create the image, run the following goal:
$ ./mvnw spring-boot:build-image -Pnative
Then, you can run the app like any other container:
$ docker run -p 8080:8080 --rm instana:0.0.1-SNAPSHOT
Application URL: http://localhost:8080/stats
For single line input (one graph), you can use postman to create a POST request with a file upload (Multipart Request)
Attach a file as an input: src/test/resources/Input/single-line-input.txt and use key as file in the body and use form-data/multipart
As shown in the small recording here.
And finally, you can also use the file multi-line-input.txt in order to test multi line support.
Note: Every line (graph) will be processed reactively and results will be streamed to the output line by line (graph by graph) over HTTP using octet streams.
Use this option if you want to explore more options such as running your tests in a native image.
The GraalVM native-image compiler should be installed and configured on your machine.
NOTE: GraalVM 22.3+ is required.
To create the executable, run the following goal:
$ ./mvnw native:compile -Pnative
Then, you can run the app as follows:
$ target/instana
You can also run your existing tests suite in a native image. This is an efficient way to validate the compatibility of your application.
To run the existing tests in a native image, run the following goal:
$ ./mvnw test -PnativeTest
