Wait for localstack to be ready

[dagrammy]

Hi everybody,

we use quarkus.aws.devservices.localstack.init-scripts-folder to initialize localstack before starting tests (e.g. to write SSM parameters).

When the tests are executed, however, localstack may not yet be ready because the script has not yet been executed to completion. For example, the SSM parameters cannot yet be found.

I have a reproducer for the problem here: https://github.com/dagrammy/ssm-devservices-test

As a workaround we currently use a @QuarkusTestResource' and the localstack endpoint/_localstack/init` to wait for localstack until it is ready.

Could something like this be built directly into the start of localstack or the dev services?

I would like to have a look at this myself, maybe someone can point me in the right direction. 🙂

You should be able to wait for a message with quarkus.aws.devservices.localstack.init-completion-msg

We do something similar here https://github.com/quarkiverse/quarkus-amazon-services/tree/main/integration-tests/src/test/resources

Thank you, I overlooked this configuration property in the documentation. 🤦

quarkus.aws.devservices.localstack.init-completion-msg works perfectly for this use case!
