編譯containerd/runc

1. 任意公有云廠商購買一臺虛擬機，綁fip（116.196.115.229）

2. 登錄vm安裝go，并設置GOROOT/GOPATH環境變量
   [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
   編輯/root/.bash_profile文件，添加如下設置后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. 編譯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. 編譯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方式運行

1. 準備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設置開機自啟動
   [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. 準備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. 啟動containerd服務
   [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)

準備rootfs和spec

1. 找另外一臺安裝了整套docker的機器（此處用本地oracle linux vm 10.12.162.67），制作測試所需的rootfs（bundle）文件

1. 創建 busybox/rootfs目錄
   [root@localhost ~]# mkdir -p busybox/rootfs

2. 拉取busybox鏡像

   [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. 創建docker

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

   85b6e32db75da001669656b452a9a65fc2de7f1a9faac95c5aedf6de1127fa15

4. 導出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. 將rootfs和spec 拷貝到containered測試節點 116.196.115.229
   [root@localhost ~]# scp -r busybox/ root@116.196.115.229:/root

測試

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

2. 利用containerd cli （/usr/local/bin/ctr）運行容器
   [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. 登錄容器驗證

   [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: <LOOPBACK,UP,LOWER_UP> 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. 刪除容器

   [root@containerd busybox]# ctr container delete busybox

   [root@containerd busybox]# ctr container list

   CONTAINER    IMAGE    RUNTIME
