localstack testcontainer startup script

Question

I'm trying to use localstack testContainer to create an S3 and SQS localy.

Here is my code to create the test container :

    @Container
static LocalStackContainer localStack =
        new LocalStackContainer(DockerImageName.parse("localstack/localstack"))
                .withClasspathResourceMapping("./localstack_bootstrap/sqs_bootstrap.sh",
                        "/etc/localstack/init/ready.d/sqs_bootstrap.sh", BindMode.READ_ONLY)
                .withServices(SQS)
                .withServices(S3)
                .waitingFor(Wait.forLogMessage("Initialized.", 1));

i tryied also with this configuration :

 .withClasspathResourceMapping("./localstack_bootstrap",
                        "/docker-entrypoint-initaws.d/", BindMode.READ_ONLY)

And here is the script i use to create localstack stuff :

c/test/resources/localstack/init.sh
#!/bin/sh
echo "start creating queue"
awslocal sqs create-queue --queue-name test-order-queue
echo "Initialized."

But it seems the script is not executed so i think i'm doing something wrong but i'm not able to figure out it.

ANy help is welcome

please try using the .withFileSystemBind(hostPath, containerPath) method. The key difference is that the classpath is a runtime concept that helps the JVM find classes and resources, while the file system is where your actual files are stored. Here's a working example. Make sure you keep the /etc/localstack/init/ready.d container path. That's where init hooks go in the ready phase: https://docs.localstack.cloud/references/init-hooks/. Hope this helps.
