+1. ensure parent cgroup cpu-rt of container, should do in start container;
+2. current do in create container, will cause failed of start container with cpu-rt after reboot machine

++# 1. 方案目标
++目标有两个：
++1. 把isulad当前的layer store里的RO层分离出来，把RW layer和RO layer分开到不同到目录存储。
++2. isulad在运行时如果在相关目录里恢复了正确的镜像数据(image和layer数据), 可实现不重启isulad, 直接使用新恢复的镜像。如果移除当前没有容器正在使用的镜像数据，可实现不重启isulad，isulad更新当前管理的镜像列表去除该镜像。只考虑完全正确的新增和删除。
++
++
++## 1.1 用法说明
++通过源码编译打开编译选项来开启功能，cmake添加`cmake -DENABLE_REMOTE_LAYER_STORE=ON ..`, 然后`make -j`即可。启动iSulad之前，还需要在配置文件`/etc/isulad/daemon.json`里面添加`"storage-enable-remote-layer": true`来打开开关。

++
++总体来说有两部分的功能：
++- iSulad原有的image storage适配分离的RO目录结构，*分离的RO目录*可用于远程挂载
++- iSulad实例同步内存数据，镜像数据和layer数据*定期更新*，不通过`isula pull` 和 `isula rmi` 等命令，直接通过分离目录里面的数据来更新镜像数据。
++
++*分离RO目录*
++修改前后storage目录结构对比：
++
++```

++        └── layer.json
++        └── b64792.tar.gz
++```
++
++以overlay-layers目录为例，创建新layer时，如果是只读层，就把层数据放到RO目录下，在RO上层目录创建软连接指向真实数据。删除layer时需要额外删除软连接。
++
++
++*定期更新*
++定期更新通过启动一个线程周期扫描`overlay`, `overlay-layers`, `overlay-image`这三个目录，通过比较当前时刻与上一时刻的目录差异，来获取镜像和层的删减情况，进而同步isulad的storage内存数据和维护软链接。

++# 4. 详细设计
++分离RO目录的关键在于适配原来的代码逻辑，原先的代码在操作镜像和层的时候，不管是RO层还是RW层，从创建到删除都是在当前目录下进行的，这就是我们额外创建一个软连接的作用:
++- RO目录的作用是为了支持远程挂载
++- 软连接的作用是模拟原来的目录结构
++
++这样以来，image module的逻辑几乎不需要改动，除了以下几点需要注意：
++- 创建和删除的时候需要处理一个额外的资源：软连接，之前只需要关注目录即可，现在如果创建的是只读层，就需要额外创建软连接，如果删除的是只读层，就需要额外删除软连接
++- 以`overlay-layers`目录为例，isulad启动时会以正则规则扫描当前目录下的子目录是否合法，所以需要屏蔽`RO`目录
++
++定时刷新的逻辑如下：
++以`overlay-image`目录的刷新为例，通过维护两个集合`new` 和 `old`, 这两个集合初始都为空，通过扫描目录里面所有的子目录，把合法的image id 加入`new`集合， 通过计算两个集合的差， 在集合`new`里面存在而在集合`old`里面不存在的id则为新增加的镜像， 在集合`old`里面存在而在集合`new`里面不存在的id则为删除的镜像。处理新增加的镜像还需要额外的一个判断，就是判断镜像的层数据是否已经加载，如果没加载则该镜像本轮不加载。`overlay-layers` 和 `overlay` 目录的处理逻辑类似。
++
++
++*可能的使用场景*
++一个可能的使用场景就是通过远程文件共享(nfs)让多台启动的isulad实例共享某些只读的数据；具体来说，在两个host A和B上都启动了iSulad, 如果A pull或者load了镜像busybox, 那么B上的isulad同样可以使用这个镜像。

++*同步问题*
++共享资源并发使用发生竞争的条件是：`two process access the same resource concurrently and at least one of the access is a writer`。这里的共享资源有：
++
++```
+++============================+         +=====================================+
++|      Sharing Resource      |         |          Storage                    |
+++============================+         +=====================================+
++| read-only overlay layers   | mounted | /var/lib/isulad/overlay/RO          |
+++----------------------------+ ======▶ +-------------------------------------+
++| reald-only layers metadata | shared  | /var/lib/isulad/overlay-layers/RO   |
+++----------------------------+         +-------------------------------------+
++| reald-only images          |         | /var/lib/isulad/overlay-images      |
+++----------------------------+         +-------------------------------------+
++
++```
++而分布在不同host上的isulad进程通过网络共享这些资源，如果不考虑新增删除的情况，不会出现资源竞争，所有的节点都是reader。
++
++对于主节点pull镜像，其他节点使用镜像的情况，主节点是writer，其他节点是reader。这时候可能出现的问题是主节点pull镜像的流程没有完全结束，但是其他节点开始使用这个不完整的镜像。对于这个问题的解决方案是通过扫描image目录来新增镜像，通过这种方式能确保一定该新增镜像的信息完整。

++至于主节点删除镜像的情况，主节点是writer，其他节点是reader，可能出现的情况是其他节点还有容器在使用镜像的时候，镜像被删除，但是根据需求场景暂不处理这种情况。其他的处理与新增镜像相同，依然以image dir作为入口，扫描发现删除的镜像。删除时需要关注layer和overlay目录下的软链接。

++# 方案目标
++
++isulad 支持使用runc作为容器runtime。用户可以在启动容器时配置`--runtime=runc`创建runtime为runc的容器：
++```bash
++$ isula run -tid -n test --runtime=runc busybox sh
++eb77c672a148cc4cefa0d6e7c5847f5a87d0c5353e245461b68820bd9af90c67
++$ isula inspect eb77 | grep -i runc
++        "ResolvConfPath": "/var/lib/isulad/engines/runc/eb77c672a148cc4cefa0d6e7c5847f5a87d0c5353e245461b68820bd9af90c67/resolv.conf",
++        "HostsPath": "/var/lib/isulad/engines/runc/eb77c672a148cc4cefa0d6e7c5847f5a87d0c5353e245461b68820bd9af90c67/hosts",
++        "LogPath": "/var/lib/isulad/engines/runc/eb77c672a148cc4cefa0d6e7c5847f5a87d0c5353e245461b68820bd9af90c67/console.log",
++            "Runtime": "runc",
++                "log.console.file": "/var/lib/isulad/engines/runc/eb77c672a148cc4cefa0d6e7c5847f5a87d0c5353e245461b68820bd9af90c67/console.log",
++```
++
++同时，也可以在`/etc/isulad/daemon.json`中配置`default-runtime`为runc并重启isulad，修改isulad创建容器时默认使用的runtime。
++```sh
++$ vim /etc/isulad/daemon.json
++	...
++   "default-runtime": "runc"
++    ...
++$ sudo isulad
++```
++
++# 总体设计
++
++由于isulad与runc之间的交互存在gap，且将容器创建成功之后，容器进程的生命周期与isulad进程的生命周期没有必然联系，因此我们设计了一个isulad-shim进程，用于isulad与runc的交互并将isulad与容器实例解耦。同时，由于只有create以及exec涉及到在容器中新建进程，因此只有这两个子命令需要创建isulad-shim。其他的子命令直接通过调用runc二进制实现。

++# 详细设计
++
++## create 实现流程
++
++isulad端：
++
++1. 创建process文件：create_process_json_file();
++2. 获得runtime二进制：get_runtime_cmd(runtime, &cmd);
++3. 利用两次fork()创建isulad-shim进程， 此时的isulad-shim进程是1号进程的子进程，与isulad无父子关系:shim_create();
++4. 若shim创建成功则直接返回成功，若失败则调用runtime_call_delete_force()将容器进程都force delete。
++
++isulad-shim端：
++
++1. 根据解析process文件新建一个process，new_process()；
++2. 开启exit_fifo：open_no_inherit("exit_fifo", O_WRONLY, -1);
++3. 为io_copy创建io_epoll_loop线程：process_io_init();
++4. 创建进行io copy的线程，并将isulad的console与runtime的console连接起来:open_io();
++5. 创建运行runtime的子进程，获得容器中进程的pid，create_process();
++6. 循环wait子进程，直到wait到的子进程为容器进程pid则退出shim进程，process_signal_handle_routine();
++
++## exec 实现流程
++
++isulad端：
++
++1. 创建process文件：create_process_json_file();
++2. 获得runtime二进制：get_runtime_cmd(runtime, &cmd);
++3. 若`--detach=false`，直接fork()创建isulad-shim进程，此时的isulad-shim进程是isulad进程的子进程，isulad进程wait等待isulad-shim进程退出；若-`-detach=true`，则与create一样，创建独立的isulad-shim进程:shim_create();
++4. 循环读取pid文件获得容器进程id说明exec命令成功，get_container_process_pid。
++
++isulad-shim端：
++
++1. 根据解析process文件新建一个process，new_process()；
++2. 为io_copy创建io_epoll_loop线程：process_io_init();
++3. 创建进行io copy的线程，并将isulad的console与runtime的console连接起来:open_io();
++4. 创建运行runtime的子进程，获得容器中进程的pid，create_process();
++5. 循环wait子进程，直到wait到的子进程为容器进程pid则退出shim进程，process_signal_handle_routine();
++
++
++
++## start 实现流程
++
++isulad端：
++
++1. 分别读取pid以及shim-pid文件获得容器进程pid以及isulad-shim pid；
++2. 依次获得容器进程以及isulad-shim进程的proc信息：util_get_process_proc_info();
++3. 根据proc信息为pid_ppid_info_t结构体赋值；
++4. 直接调用runc二进制start容器：runtime_call_simple();
++5. 之后isulad根据监听exit_fifo_fd，感知容器是否退出，从而更新容器状态。
++
++其他子命令与satrt类似，均是调用runtime_call_simple()函数直接调用runc二进制，此处不再赘述。

++# runc使用指南
++本文主要是指导iSulad社区开发者和使用者，如何配置isulad使用runc作为runtime创建容器。
++
++## 一、runc的安装
++
++`tips`: 在安装runc之前需要安装好go环境。
++
++isulad当前推荐的runc验证版本为v1.0.0-rc5。
++
++runc可以使用以下两种安装方式：
++
++1. 直接使用包管理器安装runc:
++
++```sh
++# centOS
++sudo yum install runc
++# Ubuntu
++sudo apt-get install runc
++```
++
++2. 源码编译安装runc（注意建议切换成isulad推荐的runc版本：`git checkout v1.0.0-rc5`）
++
++```sh
++# 在GOPATH/src下创建 'github.com/opencontainers' 文件夹 
++cd github.com/opencontainers
++git clone https://github.com/opencontainers/runc
++cd runc
++
++make
++sudo make install
++```
++
++还可以使用go get安装到`GOPATH`路径下（需要在GOPATH/src下创建github.com父文件夹）：
++
++```sh
++go get github.com/opencontainers/runc
++cd $GOPATH/src/github.com/opencontainers/runc
++make
++sudo make install
++```
++
++最终安装好的runc会在`/usr/local/sbin/runc`目录下。
++
++##   二、配置iSulad使用runc
++
++### 配置文件配置
++
++1. 修改isulad的daemon.json，配置isulad默认使用的runtime。
++
++```sh
++$ vim /etc/isulad/daemon.json
++	...
++   "default-runtime": "runc"
++    ...
++```
++
++2. 也可以在配置文件中配置runtimes，在其中指定使用的`path`(用于修改isulad使用的runc路径)以及`runtime-args`(对runtime所有命令配置的参数)。
++
++```sh
++"runtimes": {
++            "runc": {
++                    "path": "/usr/local/sbin/runc",
++                    "runtime-args": [
++                    ]
++            }
++    },
++```
++
++之后使用root权限启动isulad服务，使修改后的配置生效即可：
++
++```sh
++$ sudo isulad
++```
++
++### 单个容器配置
++
++使用`--runtime=runc`启动一个runtime为runc的容器。
++
++```sh
++isula run -tid -n test --runtime=runc busybox sh
++```
++
++## 三、K8s中配置pod的runtime为runc
++
++如何与kubernetes集成请参考[k8s_integration](https://gitee.com/openeuler/iSulad/blob/master/docs/manual/k8s_integration_zh.md)。
++
++### 全局配置
++
++直接参照第二节中配置文件配置的方式修改isulad默认使用的runtime为runc，则后续使用k8s启动容器时会默认使用的runtime即为runc。
++
++### 使用RuntimeClass配置
++
++RuntimeClass 是K8s的一种内置集群资源，是一种容器运行时配置，用于运行pod中的容器。
++
++1. 在`/etc/isulad/daemon.json`中配置`isulad`：
++
++   ```json
++   "runtimes": {
++               "runc-runtime": {
++                       "path": "/usr/local/sbin/runc",
++                       "runtime-args": [
++                       ]
++               }
++       },
++   ```
++
++2. 定义 `runc-runtime.yaml`，例如创建一个`runc-runtime.yaml`内容如下：(注意handler需要与daemon.json中的名称一致)
++
++   ```yamlapiVersion: v1
++   apiVersion: node.k8s.io/v1beta1
++   kind: RuntimeClass
++   metadata:
++     name: runc-runtime
++   handler: runc-runtime
++   ```
++
++   之后运行`kubectl apply -f runc-runtime.yaml`命令在kubectl中让这个配置生效。
++
++3. 之后在创建pod时，可以在其定义的yaml文件中的`spec.runtimeClassName`中设置pod使用的runtime：
++
++```yaml
++apiVersion: v1
++kind: Pod
++metadata:
++  name: runc-pod-example
++spec:
++  runtimeClassName: runc-runtime
++  containers:
++  - name: runc-pod
++    image: busybox:latest
++    command: ["/bin/sh"]
++    args: ["-c", "sleep 1000"]
++```
