Raksh Agent

This is a modified Kata agent to manage all contianers life-cycle operation inside the secure virtual machine (SVM) of the Raksh Secure Container project. For details on Raksh please refer to the details here. You'll need to build the agent and the initrd

The agent manages container processes inside the VM, on behalf of the runtime running on the host.

Build and install Kata Agent (aka Raksh Agent)

$ mkdir -p $GOPATH/src/github.com/kata-containers
$ cd $GOPATH/src/github.com/kata-containers
$ git clone https://github.com/ibm/raksh-agent.git agent
$ cd agent 
$ git checkout -b 1.9.1-raksh-agent origin/1.9.1-raksh-agent 
$ make && sudo make install

Get the osbuilder

$ go get -d -u github.com/kata-containers/osbuilder

Build and install the image-tools binary

$ go get -d github.com/opencontainers/image-tools/cmd/oci-image-tool
$ cd $GOPATH/src/github.com/opencontainers/image-tools/ && make all && sudo make install

Note:

• The distro on which you build the binary should match the distro you base your initrd rootfs on

Create an initrd image

Create a local rootfs for initrd image

$ export ROOTFS_DIR="${GOPATH}/src/github.com/kata-containers/osbuilder/rootfs-builder/rootfs"
$ sudo rm -rf ${ROOTFS_DIR}
$ cd $GOPATH/src/github.com/kata-containers/osbuilder/rootfs-builder
$ script -fec 'sudo -E GOPATH=$GOPATH AGENT_INIT=yes EXTRA_PKGS="skopeo" USE_DOCKER=true SECCOMP=no AGENT_SOURCE_BIN=/usr/bin/kata-agent ./rootfs.sh fedora'
$ scp /usr/bin/oci-image-tool ${ROOTFS_DIR}/usr/bin/.

Build an initrd image

$ cd $GOPATH/src/github.com/kata-containers/osbuilder/initrd-builder
$ script -fec 'sudo -E AGENT_INIT=yes USE_DOCKER=true ./initrd_builder.sh ${ROOTFS_DIR}'

Install the initrd image

$ commit=$(git log --format=%h -1 HEAD)
$ date=$(date +%Y-%m-%d-%T.%N%z)
$ image="kata-containers-initrd-${date}-${commit}"
$ sudo install -o root -g root -m 0640 -D kata-containers-initrd.img "/usr/share/kata-containers/${image}"
$ (cd /usr/share/kata-containers && sudo ln -sf "$image" kata-containers-initrd.img)
