编译containerd/runc

  1. 任意公有云厂商购买一台虚拟机，绑fip（116.196.115.229）

  2. 登录vm安装go，并设置GOROOT/GOPATH环境变量
    [root@containerd bin]# wget https://dl.google.com/go/go1.12.5.linux-amd64.tar.gz
    [root@containerd bin]# tar -xvf go1.12.5.linux-amd64.tar.gz -C /usr/local

    [root@containerd bin]# /usr/local/go/bin/go version

    go version go1.12.5 linux/amd64
    编辑/root/.bash_profile文件，添加如下设置后sourcePATH=$PATH:/usr/local/go/bin
    export PATH

    export GOROOT=/usr/local/go/
    export GOPATH=/root/go[root@containerd ~]# source .bash_profile

  3. Build the development environment

    [root@containerd ~]# go get github.com/containerd/containerd
    [root@containerd ~]# wget -c https://github.com/google/protobuf/releases/download/v3.5.0/protoc-3.5.0-linux-x86_64.zip
    [root@containerd ~]# unzip protoc-3.5.0-linux-x86_64.zip -d /usr/local
    [root@containerd ~]# yum install -y btrfs-progs-devel libseccomp-devel

  4. 编译runc
    [root@containerd ~]# go get github.com/opencontainers/runc[root@containerd containerd]# cd $GOPATH/src/github.com/opencontainers/runc

    [root@containerd runc]# make

    go build -buildmode=pie  -ldflags "-X main.gitCommit="eb4aeed24ffbf8e2d740fafea39d91faa0ee84d0">

    [root@containerd runc]# make install

    install -D -m0755 runc /usr/local/sbin/runc

    [root@containerd runc]# ls -rtl /usr/local/sbin

    total 11752

    -rwxr-xr-x 1 root root 12031832 May 10 17:33 runc

    [root@containerd runc]# runc --version

    runc version 1.0.0-rc8+dev

    commit: eb4aeed24ffbf8e2d740fafea39d91faa0ee84d0

    spec: 1.0.1-dev

  5. 编译containerd
    [root@containerd runc]# cd $GOPATH/src/github.com/containerd/containerd
    [root@containerd containerd]# make
    + bin/ctr
    + bin/containerd
    + bin/containerd-stress
    + bin/containerd-shim
    + bin/containerd-shim-runc-v1
    + bin/containerd-shim-runc-v2
    + binaries
    [root@containerd containerd]# make install
    + install bin/ctr bin/containerd bin/containerd-stress bin/containerd-shim bin/containerd-shim-runc-v1 bin/containerd-shim-runc-v2

    [root@containerd containerd]# ls -rtl /usr/local/bin

    total 133152

    -rwxr-x--- 1 root root  4433736 Nov 14  2017 protoc

    -rwxr-xr-x 1 root root 29709728 May 10 17:35 ctr

    -rwxr-xr-x 1 root root 51831136 May 10 17:35 containerd

    -rwxr-xr-x 1 root root 25094688 May 10 17:35 containerd-stress

    -rwxr-xr-x 1 root root  7302016 May 10 17:35 containerd-shim

    -rwxr-xr-x 1 root root  8980256 May 10 17:35 containerd-shim-runc-v1

    -rwxr-xr-x 1 root root  8980320 May 10 17:35 containerd-shim-runc-v2


    [root@containerd containerd]# containerd --version
    containerd github.com/containerd/containerd v1.2.0-551-g57fbb16 57fbb16234fa6c8a61e5e907a4148ea3b05bce1d

  6. containerd以daemon方式运行

    1. 准备containered.service文件
      [root@containerd ~]# cat /usr/lib/systemd/system/containerd.service
      [Unit]
      Description=containerd container runtime
      Documentation=https://containerd.io
      After=network.target

      [Service]
      ExecStartPre=-/sbin/modprobe overlay
      ExecStart=/usr/local/bin/containerd

      Delegate=yes
      KillMode=process
      # Having non-zero Limit*s causes performance problems due to accounting overhead
      # in the kernel. We recommend using cgroups to do container-local accounting.
      LimitNPROC=infinity
      LimitCORE=infinity
      LimitNOFILE=1048576
      # Comment TasksMax if your systemd version does not supports it.
      # Only systemd 226 and above support this version.
      TasksMax=infinity

      [Install]
      WantedBy=multi-user.target

    2. enable设置开机自启动
      [root@containerd system]# systemctl enable containerd.service
      Created symlink from /etc/systemd/system/multi-user.target.wants/containerd.service to /usr/lib/systemd/system/containerd.service.

    3. 准备containerd配置文件

      [root@containerd ~]# cat /etc/containerd/config.toml

      subreaper = true  

      oom_score = -999

      [debug]

       level = "debug"

      [metrics]

       address = "127.0.0.1:1338"

      [plugins.linux]

       runtime = "runc"

       shim_debug = true

    4. 启动containerd服务
      [root@containerd system]# systemctl start containerd.service
      [root@containerd system]# systemctl status containerd.service
      ● containerd.service - containerd container runtime
         Loaded: loaded (/usr/lib/systemd/system/containerd.service; enabled; vendor preset: disabled)

准备rootfs和spec

  1. 找另外一台安装了整套docker的机器（此处用本地oracle linux vm 10.12.162.67），制作测试所需的rootfs（bundle）文件

    1. 创建 busybox/rootfs目录
      [root@localhost ~]# mkdir -p busybox/rootfs

    2. 拉取busybox镜像

      [root@localhost ~]# docker pull busybox

      Using default tag: latest

      latest: Pulling from library/busybox

      53071b97a884: Pull complete

      Digest: sha256:32f65f5aae307c171fc69ce52be3c8b09675164a610a88efa607449311186378

      Status: Downloaded newer image for busybox:latest

    3. 创建docker

      [root@localhost ~]# docker create --name tempbusybox busybox

      85b6e32db75da001669656b452a9a65fc2de7f1a9faac95c5aedf6de1127fa15

    4. 导出rootfs和spec

      [root@localhost ~]# docker export tempbusybox | tar -C busybox/rootfs -xf -

      [root@localhost ~]# cd busybox/ &&  /usr/bin/docker-runc spec

      [root@localhost busybox]# ls

      config.json  rootfs

      [root@localhost busybox]# ls rootfs/

      bin  dev  etc  home  proc  root  sys  tmp  usr  var

    5. 将rootfs和spec 拷贝到containered测试节点 116.196.115.229
      [root@localhost ~]# scp -r busybox/ root@116.196.115.229:/root

测试

  1. [root@containerd busybox]# cd /root/busybox

  2. 利用containerd cli （/usr/local/bin/ctr）运行容器
    [root@containerd busybox]# ctr run -t -d --rootfs rootfs busybox /bin/sh

    [root@containerd busybox]# ctr container list

    CONTAINER    IMAGE    RUNTIME                           

    busybox      -        io.containerd.runtime.v1.linux

    [root@containerd busybox]# ps -ef |grep container

    root      9539     1  0 21:22 ?        00:00:03 /usr/local/bin/containerd

    root     15285  9539  0 22:02 ?        00:00:00 containerd-shim -namespace default -workdir /var/lib/containerd/io.containerd.runtime.v1.linux/default/busybox -address /run/containerd/containerd.sock -containerd-binary /usr/local/bin/containerd -debug

  3. 登录容器验证

    [root@containerd busybox]# ctr tasks list

    TASK       PID      STATUS    

    busybox    15301    RUNNING

    [root@containerd busybox]# ctr tasks exec -t  --exec-id 15301 busybox /bin/sh

    / # hostname

    containerd

    / # ip a

    1: lo: mtu 65536 qdisc noqueue qlen 1

        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

        inet 127.0.0.1/8 scope host lo

           valid_lft forever preferred_lft forever

        inet6 ::1/128 scope host

           valid_lft forever preferred_lft forever

  4. stop容器
    [root@containerd busybox]# ctr tasks kill --signal 9 busybox

    [root@containerd busybox]# ctr tasks list

    TASK       PID      STATUS    

    busybox    15301    STOPPED

  5. 删除容器

    [root@containerd busybox]# ctr container delete busybox

    [root@containerd busybox]# ctr container list

    CONTAINER    IMAGE    RUNTIME
