How do I properly configure Hazelcast for the Digital Ocean App platform?

I have an HTTP web server that runs on the Digital Ocean Apps platform. I was wondering if they support Hazelcast. However, I don’t know if network discovery will work properly on the apps platform.

I don’t want to enable Hazelcast TCP discovery if machines outside of the apps platform can join the Hazelcast cluster. I only want machines within the App platform to join the cluster.

I believe that going with a Droplet may provide a more suitable environment compared to the App Platform.

Droplets offer a higher degree of control and flexibility. This is particularly beneficial for Hazelcast deployments, as it allows for precise configuration of network settings and performance parameters. In environments where specific customizations are necessary, Droplets provide the necessary infrastructure freedom.

Regarding the Digital Ocean App Platform, it does not inherently support Java as a buildpack, which is a critical consideration given that Hazelcast is Java-based. This constraint could significantly impact the deployment process and overall functionality.

However, if you still want to give the App Platform a try, you could use a Dockerfile or a Docker image. By containerizing your Hazelcast application with Docker, you can encapsulate the Java environment within the container.

Hope that this helps.
