Clear Containres 3.0 and Containerd

Clear Containers is compatible to work with containerd 1.0 and docker 17.10 ( that uses containerd 1.0 )

Install

Install docker 17.10

Docker 17.10+ can be intalled from docker testing repository to do that follow the next instructions:

curl -s https://yum.dockerproject.org/gpg | sudo apt-key add
sudo apt-key fingerprint 58118E89F3A912897C070ADBF76221572C52609D
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) test
sudo apt-get update
sudo apt-get install -y docker-ce

Then configure docker to use cc-rutntime:

sudo mkdir -p /etc/systemd/system/docker.service.d/
cat <<EOF | sudo tee /etc/systemd/system/docker.service.d/clear-containers.conf
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -D --add-runtime cc-runtime=/usr/bin/cc-runtime --default-runtime=cc-runtime
EOF
sudo systemctl daemon-reload
sudo systemctl enable docker.service
sudo systemctl restart docker
sudo systemctl enable cc-proxy.socket

Install cri-containerd

cri-containerd is a cri implementation that uses containerd for container creation. Follow the next instructions to install and configure cri-contaienrd to work with cc-runtime.

#Install cri-contaienrd depedencies 
sudo apt-get install libseccomp-dev libapparmor-dev  btrfs-tools socat
go get -d github.com/kubernetes-incubator/cri-containerd
cd ${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/
git fetch
git checkout -B jcvenegas/pod-annotations cbda4256cda497f06e7c1c808dbe88471ec035ea
git pull -f https://github.com/jcvenegas/cri-containerd.git clear-containers
#This will install containerd
make install.deps
make
sudo make install
#check integration tests are working with runc
CRI_CONTAINERD_FLAGS="--containerd-runtime-engine runc" make test-integration

** Note cc-runtime is not working with macvtap model, need rework or modify manually to use tap model
