nitro-cli terminate-enclave --all
nitro-cli run-enclave --eif-path simple-echo-enclave.eif --memory 2048 --cpu-count 2 --enclave-cid 5 --debug-mode

debug-mode Console

nitro-cli console --enclave-id $(nitro-cli describe-enclaves | jq -r '.[0].EnclaveID')

Run Host App

Ensure that you have the lib libvsockj-native-1.0-SNAPSHOT.so somewhere on your Java Classpath. Usually you can just copy it to /usr/lib64.

CID=5 java -jar simple-echo-host/target/nitro-enclaves-simple-echo-host-1.0.0-SNAPSHOT.jar

You should see the following output, where i-09eb... is the Nitro Module ID:
