    Quick Start - Docker

    Get the static binaries

    The static binaries are posted on our release page, and 1.5.0 can be obtained as follows:

    wget https://github.com/kata-containers/runtime/releases/download/1.5.0/kata-static-1.5.0-x86_64.tar.xz

    The tarball is designed to be decompressed into /, placing all of the files within /opt/kata/. The runtime configuration is expected to land at /opt/kata/share/defaults/kata-containers/configuration.toml. Your mileage will vary if you make further changes. To install Kata on your system:

    sudo tar -xvf kata-static-1.5.0-x86_64.tar.xz -C /

    1. Install the latest version of Docker with the following commands:

      Notes:

      $ sudo -E apt-get -y install apt-transport-https ca-certificates software-properties-common
$ curl -sL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ arch=$(dpkg --print-architecture)
$ sudo -E add-apt-repository "deb [arch=${arch}] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
$ sudo -E apt-get update
$ sudo -E apt-get -y install docker-ce

      For more information on installing Docker please refer to the Docker Guide.

    2. Configure Docker to use Kata Containers by default with ONE of the following methods:

      1. systemd (this is the default and is applied automatically if you select the automatic installation option)

        $ sudo mkdir -p /etc/systemd/system/docker.service.d/
$ cat <<EOF | sudo tee /etc/systemd/system/docker.service.d/kata-containers.conf
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -D --add-runtime kata-runtime=/usr/bin/kata-runtime --default-runtime=kata-runtime
EOF

      2. Docker daemon.json

        Create docker configuration folder.

        $ sudo mkdir -p /etc/docker

        Add the following definitions to /etc/docker/daemon.json:

        {
  "default-runtime": "kata-runtime",
  "runtimes": {
    "kata-runtime": {
      "path": "/usr/bin/kata-runtime"
    }
  }
}

    3. Restart the Docker systemd service with the following commands:

      $ sudo systemctl daemon-reload
$ sudo systemctl restart docker


      root@ubuntu:~# systemctl restart docker
Job for docker.service failed because the control process exited with error code.

    4. Run Kata Containers

      You are now ready to run Kata Containers:

      $ sudo docker run busybox uname -a

      The previous command shows details of the kernel version running inside the container, which is different to the host kernel version.

    docker run --rm -it --runtime kata-runtime busybox uname -r
docker: Error response from daemon: OCI runtime create failed: Failed to check if grpc server is working: rpc error: code = Unavailable desc = transport is closing: unknown.
    root@ubuntu:/home/ubuntu# docker run --rm -it --runtime kata-runtime busybox uname -r

    https://github.com/kata-containers/kata-containers/issues/28

    https://my.oschina.net/u/4284509/blog/3933348

    具体安装步骤为：

    1.进入qemu源码目录

    执行./configure --enable-virtfs,这里是为了开启虚拟文件系统，如果不添加这个参数.在运行docker启动kata-container时，会报'virtio-9p-pci' is not a valid device model name: unknown的错误

    2.执行make&&sudo make install

    3.将/usr/local/bin/qemu-system-x86_64拷贝为/usr/bin/qemu-lite-system-x86_64

    Kata-container 环境搭建手顺

    apt-get -y install  libcap-ng-dev 

    root@ubuntu:/opt/gopath/src/github.com/kata-containers/osbuilder/initrd-builder# docker run --rm -it --runtime kata-runtime busybox uname -r
docker: Error response from daemon: OCI runtime create failed: failed to launch qemu: exit status 1, error messages from qemu log: qemu-system-aarch64: Property '.pmu' not found: unknown.

    docker run --rm -it --runtime kata-runtime busybox uname -r
