To create the docker group and add your user:

Create the docker group.
```
$ sudo groupadd docker
```
Add your user to the docker group.
```
$ sudo usermod -aG docker $USER
```
Log out and log back in so that your group membership is re-evaluated.

If testing on a virtual machine, it may be necessary to restart the virtual machine for changes to take effect.

On a desktop Linux environment such as X Windows, log out of your session completely and then log back in.

On Linux, you can also run the following command to activate the changes to groups:
```
$ newgrp docker 
```
Verify that you can run docker commands without sudo.
```
$ docker run hello-world
```

然后另外打开一个终端执行

介绍

gVisor是用Go实现的用户空间内核。包括OCI运行时runsc，隔离应用和主机内核。

容器并不是沙箱。尽管容器改变了我们开发、打包和部署应用的方式，但共享一个内核带来性能和效率的同时，也让容器逃离成为可能。

gVisor是容器的用户态内核，限制应用访问内核接口的同时允许应用获得需要的特性。

适用场景：

小容器，快速启动，高密度（如：FaaS？）

不适用场景：

可信镜像
系统调用频繁
直接访问硬件

隔离机制

容器现有的安全隔离手段包括：用户/组、Capabilities、Cgroup和名字空间。

除此之外，还有其它增强容器隔离性的手段，包括虚拟化、基于规则的安全策略和沙箱。

虚拟化

通过VMM将虚拟硬件暴露给虚拟机内核，容器运行在虚拟机中可以获得更好的隔离性和兼容性，但通常需要额外的代理和更多的资源。如KVM、Xen。

基于规则

为应用或容器制定专门的安全策略，让暴露面尽量小，但不能在新的应用上通用。如seccomp、SELinux和AppArmor。

gVisor

原理

架构

gVisor解析应用的系统调用，并进行相应的处理，而不是简单的转发给主机内核。gVisor实现了内核中大部分的基础组件（primitives），包括信号、文件系统、管道、内存管理、futexes等，并在此基础上实现列完整的系统调用处理方法。

gVisor容器运行时分为2个独立进程，Sentry进程负责执行用户代码，处理系统调用，而文件系统相关的操作则由Gofer进程处理，它们之间通过9P连接。

文件系统

Gofer作为文件系统代理，按应用的需求打开主机文件。Sentry在空用户名字空间运行，gVisor的系统调用会经过seccomp filters限制，实现深度防御（defense-in-depth）。

网络

Sentry实现了自己的网络栈（netstack），负责TCP连接状态、控制消息和包组装等工作，实现了与主机网络栈的隔离。数据链路层的包会直接写入优Docker或Kubernetes创建的网络名字空间虚拟设备上。

同时也支持网络透传模式，但这样会降低隔离性。

平台

Sentry需要平台（platform）实现基本的上下文切换和内存映射功能。目前支持两种平台：

Ptrace，使用SYSEMU功能执行用户代码，无需执行主机系统调用。
KVM，Sentry同时充当虚拟机OS和VMM，之间无缝切换。沙箱还是进程模型，没有虚拟硬件层，只是利用了现代处理器的虚拟化扩展提高隔离性和地址空间切换性能。

         "path": "/usr/bin/runsc"
         "runtimeArgs": [

             "--platform=ptrace"
         ]
     }
 }
}
$ sudo systemctl restart docker

验证 ``` $ sudo docker run –runtime=runsc hello-world Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps:
The Docker client contacted the Docker daemon.
The Docker daemon pulled the “hello-world” image from the Docker Hub. (amd64)
The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading.
The Docker daemon streamed that output to the Docker client, which sent it to your terminal. ```

注：由于网络问题，无法访问golang.org导致编译失败，需要修改依赖的路径

WORKSPACE文件允许用户的目标依赖其他文件系统的目标或者从网上下载的目标。WORKSPACE文件的语法和BUILD文件一致，不过会用到一些特定的内置rule，细节参考下一个章节的内容。

一共有三种外部依赖的主要类型：

1、依赖于其他Bazel工程

根据这个Bazel工程所处的位置不同，调用不同的内置rule来获得：

local_repository：本地
git_repository：git仓库
http_archive：网络下载

假如现在有个工程my-project/，需要依赖与另一个工程coworkers-project/。这两个都是Bazel工程，那么需要在my_project/WORKSPACE下添加：

local_repository(
name = “coworkers_project”,
path = “/path/to/coworkers-project”,
)
