 This sample creates an encrypted and signed contract and stores it locally in a file. You can later use the contract to provision a HPVS for VPC instance.
 The contract will define the container image, the container registry and the credentials for pulling your workload container image, as well as a server certificate and server key.

 The contract will be written to the file `build/contract.yml` and can now be used for e.g. provisining a HPVS for VPC instance.
 
 Note that you will need to create a public gateway in your VPC before creating the HPVS for VPC instance. This is necessary to allow the HPVS for VPC instance to reach your Log instance through the public gateway. Also assign a floating IP to your HPVS for VPC instance.
