The wizard validates Docker, activates a client license, generates a unique 3072-bit installation signing key, registers the installation, and writes the deployment files. The license key is never persisted.

java -jar target/cygnus-installer-1.0.0-SNAPSHOT.jar

Set CYGNUS_CLOUD_URL before execution. The wizard asks where deployment files should be written and offers CYGNUS_INSTALL_OUTPUT as the default.

The selected output directory contains:

compose.yml
config/
  installation.yml
  keys/
    client-signing-private.pem
    client-signing-public.pem

The private key is created with owner-only permissions on POSIX systems. The plaintext installation license key is never written to the output directory.
