编译containerd/runc
任意公有云厂商购买一台虚拟机，绑fip（116.196.115.229）
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
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
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

containerd以daemon方式运行
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

# in the kernel. We recommend using cgroups to do container-local accounting.

# Comment TasksMax if your systemd version does not supports it.

[Install]
WantedBy=multi-user.target
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.
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"

启动containerd服务
[root@containerd system]# systemctl start containerd.service
[root@containerd system]# systemctl status containerd.service

准备rootfs和spec
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
创建 busybox/rootfs目录
[root@localhost ~]# mkdir -p busybox/rootfs
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
创建docker
[root@localhost ~]# docker create --name tempbusybox busybox
85b6e32db75da001669656b452a9a65fc2de7f1a9faac95c5aedf6de1127fa15
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
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
[root@containerd busybox]# cd /root/busybox
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

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

stop容器
[root@containerd busybox]# ctr tasks kill --signal 9 busybox
[root@containerd busybox]# ctr tasks list
TASK PID STATUS
busybox 15301 STOPPED
删除容器
[root@containerd busybox]# ctr container delete busybox
[root@containerd busybox]# ctr container list
