%description
A collection of tools and commands used for managing the lifecycle of
enclaves. The Nitro CLI needs to be installed on the parent instance,
and it can be used to start, manage, and terminate enclaves.

%package -n aws-nitro-enclaves-binaryblobs-upstream
Summary:        Upstream kernel binary for AWS Nitro Enclaves
Provides:       aws-nitro-enclaves-binaryblobs = %version-%release
%description  -n aws-nitro-enclaves-binaryblobs-upstream
This package contains a kernel binary and a helper binary, which is
used by the nitro-cli build-enclave command to generate a Enclave
Image File.

%package -n system-group-%ne_system_group
Summary:        System group %ne_system_group for AWS Nitro Enclaves

Nitro Enclaves are "secondary VMs" running in an EC2 instance.
Their only storage is the memory which is assigned to them.
Their only way to communicate with the primary is the usage of AF_VSOCK.
The "primary VM" releases some of its memory and cpus, which is then assigned to the enclaves.
This is done by nitro-enclaves-allocator.service, which uses
%_sysconfdir/nitro_enclaves/allocator.yaml as configuration file.
This systemd service has to be enabled manually, and started:
  systemctl enable nitro-enclaves-allocator
  systemctl start nitro-enclaves-allocator

This command has to be used to run an existing Enclave Image File:
  nitro-cli run-enclave --eif-path /path/to/file.eif --cpu-count 2 --memory 512

How to build and run an example enclave:
  zypper in -y docker
  systemctl enable docker
  systemctl start docker
  docker pull opensuse/leap
  tee Dockerfile <<'_EOF_'
FROM opensuse/leap
ENV HELLO="Hello from the enclave side!"
COPY hello.sh /bin/hello.sh
CMD ["/bin/hello.sh"]
_EOF_
  tee hello.sh <<'_EOF_'
