Setup CCF Runtime Environment¶

To run a CCF application, installing the ccf_<platform> RPM package is sufficient. This package contains cchost and expresses runtime dependencies.

CCF releases are available on the GitHub repository release page. They can be installed as follows, for the SNP and Virtual platforms:

SNP

# Set CCF_VERSION to most recent LTS release
$ export CCF_VERSION=$(curl -Ls -o /dev/null -w %{url_effective} https://github.com/microsoft/CCF/releases/latest | sed 's/^.*ccf-//')
# Alternatively, set this manually, e.g.:
# export CCF_VERSION=6.0.0
$ wget https://github.com/microsoft/CCF/releases/download/ccf-${CCF_VERSION}/ccf_snp_${CCF_VERSION}_x86_64.rpm
$ sudo tdnf install ./ccf_snp_${CCF_VERSION}_x86_64.rpm

The following command can be run to verify that CCF was installed successfully:

$ /opt/ccf_snp/bin/cchost --version
CCF host: ccf-<version>
Platform: SNP

Virtual

# Set CCF_VERSION to most recent LTS release
$ export CCF_VERSION=$(curl -Ls -o /dev/null -w %{url_effective} https://github.com/microsoft/CCF/releases/latest | sed 's/^.*ccf-//')
# Alternatively, set this manually, e.g.:
# export CCF_VERSION=6.0.0
$ wget https://github.com/microsoft/CCF/releases/download/ccf-${CCF_VERSION}/ccf_virtual_${CCF_VERSION}_x86_64.rpm
$ sudo tdnf install ./ccf_virtual_${CCF_VERSION}_x86_64.rpm

Warning

Virtual mode does not provide any security guarantees and should be used for development purposes only.

The following command can be run to verify that CCF was installed successfully:

$ /opt/ccf_virtual/bin/cchost --version
CCF host: ccf-<version>
Platform: Virtual
