The server provides the same APIs as the cml-control tool does.

Manual Test

Query all containers:

curl http://localhost:8080/list

Create container:

curl http://localhost:8080/create \
    --include \
    --header "Content-Type: application/json" \
    --request "POST" \
    --data "{'test': 'test-string'}"

Test with Gyroid-VM (gyroidos-ui-backend in C0)

# Start Gyroid QEMU VM
./scripts/gyroid-deploy.sh <gyroid-image>

# Copy gyroidos-ui-backend into C0
./scripts/gyroid-update-rest-bridge.sh

The gyroidos-ui-backend is serving now within the C0 on 0.0.0.0:8080, which is forwarded by QEMU. The gyroid-demo can access the server via localhost:8080. For a manual test, you can run curl http://localhost:8080/list.

If required, the gyroidos-ui-backend can also be started manually:

# SSH into VM
ssh -p 2323 -o StrictHostKeyChecking=no -o UserKnownHostsFile=gyroid.vm_key -o GlobalKnownHostsFile=/dev/null root@localhost

# Run gyroidos-ui-backend
/home/root/gyroidos-ui-backend

Test with Gyroid-VM (gyroidos-ui-backend on host, debug image)

Port forwarding

# Retrieve the PID of the init-process of the core container (user 100000)
ps aux

# Switch to the core container
nsenter -a -t <pid-core-container>

# Forward traffic to CML and tpm2d
iptables -t nat -A PREROUTING -p tcp -i cmleth0 --dport 8080 -j DNAT --to-destination 172.23.0.1:8080 && iptables -A FORWARD -p tcp -d 172.23.0.1 --dport 8080 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT

# Switch back
exit

# Put gyroidos-ui-backend into extcmld folder

# Start gyroidos-ui-backend
/data/extcmld/gyroidos-ui-backend

QEMU:

-net nic -net user,hostfwd=tcp::8080-:8080 \
