Demo app for testing Hazelcast in embedded mode forming a cluster

Local test

To know what to expect in other environments, run and test this locally first. Run this app twice on you localhost:

mvn spring-boot:run
mvn spring-boot:run -Dserver.port=8081

Then get Hazelcast cluster info from the info endpoint:

curl localhost:8080/info | jq

You should see 2 entries in the hazelcastCluster array since you've started the app twice

| jq in the above command is optional, but very helpful to read JSON

Now test writing to one node and reading to another:

curl localhost:8080/write?value=321
curl localhost:8081/read

Assert that you see the same value that you've written to the one node, coming from from the other.

Test in PCF (or other target env)

Enable container-to-container communication and test:

mvn package
cf push hazelcast1 -p ./target/hazelcast-demo-0.0.1-SNAPSHOT.jar
cf push hazelcast2 -p ./target/hazelcast-demo-0.0.1-SNAPSHOT.jar

Do the same testing on hazelcast1 and hazelcast2 that we did with localhost:8080 and localhost:8081 locally.

Happy Hazelcasting!
