# KubeVPN
[English](README.md) | [中文](README_ZH.md) | [维基](https://github.com/wencaiwulue/kubevpn/wiki/%E6%9E%B6%E6%9E%84)
KubeVPN 是一个云原生开发工具, 可以在本地连接云端 kubernetes 网络的工具，可以在本地直接访问远端集群的服务。也可以在远端集群访问到本地服务，便于调试及开发。同时还可以使用开发模式，直接在本地使用 Docker
将远程容器运行在本地。
## 快速开始
#### 从 Github release 下载编译好的二进制文件
[链接](https://github.com/wencaiwulue/kubevpn/releases/latest)
#### 从 自定义 Krew 仓库安装
```shell
(
kubectl krew index add kubevpn https://github.com/wencaiwulue/kubevpn.git && \
kubectl krew install kubevpn/kubevpn && kubectl kubevpn
)
```
#### 自己构建二进制文件
```shell
(
git clone https://github.com/wencaiwulue/kubevpn.git && \
cd kubevpn && make kubevpn && ./bin/kubevpn
)
```
#### 安装 bookinfo 作为 demo 应用
```shell
kubectl apply -f https://raw.githubusercontent.com/wencaiwulue/kubevpn/master/samples/bookinfo.yaml
```

### 本地进入开发模式 🐳
将 Kubernetes pod 运行在本地的 Docker 容器中，同时配合 service mesh, 拦截带有制定 header 的流量到本地，或者所有的流量到本地。这个开发模式依赖于本地 Docker .
```shell

此时本地会启动两个 container, 对应 pod 容器中的两个 container, 并且共享端口, 可以直接使用 localhost:port 的形式直接访问另一个 container,
并且, 所有的环境变量、挂载卷、网络条件都和 pod 一样, 真正做到与 kubernetes 运行环境一致。
```shell
➜ ~ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
de9e2f8ab57d nginx:latest "/docker-entrypoint.…" 5 seconds ago Up 5 seconds nginx_kube-system_kubevpn_e21d8

➜ ~
```
如果你想指定在本地启动容器的镜像, 可以使用参数 `--docker-image`, 当本地不存在该镜像时, 会从对应的镜像仓库拉取。如果你想指定启动参数，可以使用 `--entrypoint`
参数，替换为你想要执行的命令，比如 `--entrypoint /bin/bash`, 更多使用参数，请参见 `kubevpn dev --help`.
### DinD ( Docker in Docker ) 在 Docker 中使用 kubevpn
如果你想在本地使用 Docker in Docker (DinD) 的方式启动开发模式, 由于程序会读写 `/tmp` 目录，您需要手动添加参数 `-v /tmp:/tmp`, 还有一点需要注意, 如果使用 DinD
模式，为了共享容器网络和 pid, 还需要指定参数 `--network`
例如:
```shell
docker run -it --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /tmp:/tmp -v /Users/naison/.kube/config:/root/.kube/config naison/kubevpn:v1.1.21
```
```shell
➜ ~ docker run -it --privileged -c authors -v /var/run/docker.sock:/var/run/docker.sock -v /tmp:/tmp -v /Users/naison/.kube/config:/root/.kube/config naison/kubevpn:v1.1.21
root@4d0c3c4eae2b:/# hostname
4d0c3c4eae2b
root@4d0c3c4eae2b:/# kubevpn -n kube-system --image naison/kubevpn:v1.1.21 --headers user=naison --network container:4d0c3c4eae2b --entrypoint /bin/bash dev deployment/authors
----------------------------------------------------------------------------------
Warn: Use sudo to execute command kubevpn can not use user env KUBECONFIG.
Because of sudo user env and user env are different.
Current env KUBECONFIG value:

## 问答
### 1，依赖的镜像拉不下来，或者内网环境无法访问 docker.io 怎么办？
答：有两种方法可以解决
- 第一种，在可以访问 docker.io 的网络中，将命令 `kubevpn version` 中的 image 镜像， 转存到自己的私有镜像仓库，然后启动命令的时候，加上 `--image 新镜像` 即可。
例如:
``` shell
➜ ~ kubevpn version
KubeVPN: CLI
Version: v1.1.14
Image: docker.io/naison/kubevpn:v1.1.14
Branch: master
Git commit: 87dac42dad3d8f472a9dcdfc2c6cd801551f23d1
Built time: 2023-01-15 04:19:45
Built OS/Arch: linux/amd64
Built Go version: go1.18.10
➜ ~
```
镜像是 `docker.io/naison/kubevpn:v1.1.14`，将此镜像转存到自己的镜像仓库。
```text
docker pull docker.io/naison/kubevpn:v1.1.14
docker tag docker.io/naison/kubevpn:v1.1.14 [镜像仓库地址]/[命名空间]/[镜像仓库]:[镜像版本号]
docker push [镜像仓库地址]/[命名空间]/[镜像仓库]:[镜像版本号]
```
然后就可以使用这个镜像了，如下：
```text
➜ ~ kubevpn connect --image docker.io/naison/kubevpn:v1.1.14
got cidr from cache
traffic manager not exist, try to create it...
pod [kubevpn-traffic-manager] status is Running
...
```
- 第二种，使用选项 `--transfer-image`, 这个选项将会自动转存镜像到选项 `--image` 指定的地址。
例如：
```shell
➜ ~ kubevpn connect --transfer-image --image nocalhost-team-docker.pkg.coding.net/nocalhost/public/kubevpn:v1.1.33
Password:
v1.1.33: Pulling from naison/kubevpn

```
### 2，在使用 `kubevpn dev` 进入开发模式的时候,有出现报错 137, 改怎么解决 ?
```text
dns service ok
tar: Removing leading `/' from member names
tar: Removing leading `/' from hard link targets
/var/folders/30/cmv9c_5j3mq_kthx63sb1t5c0000gn/T/7375606548554947868:/var/run/secrets/kubernetes.io/serviceaccount

$ Status: , Code: 137
prepare to exit, cleaning up
port-forward occurs error, err: lost connection to pod, retrying
update ref count successfully
ref-count is zero, prepare to clean up resource
clean up successful
```
这是因为你的 `Docker-desktop` 声明的资源, 小于 container 容器启动时所需要的资源, 因此被 OOM 杀掉了, 你可以增加 `Docker-desktop` 对于 resources
的设置, 目录是：`Preferences --> Resources --> Memory`
### 3，使用 WSL( Windows Sub Linux ) Docker, 用命令 `kubevpn dev` 进入开发模式的时候, 在 terminal 中无法提示链接集群网络, 这是为什么, 如何解决?
答案: 这是因为 WSL 的 Docker 使用的是 主机 Windows 的网络, 所以即便在 WSL 中启动 container, 这个 container 不会使用 WSL 的网络，而是使用 Windows 的网络。
解决方案:
- 1): 在 WSL 中安装 Docker, 不要使用 Windows 版本的 Docker-desktop
- 2): 在主机 Windows 使用命令 `kubevpn connect`, 然后在 WSL 中使用 `kubevpn dev` 进入开发模式
- 3): 在主机 Windows 上启动一个 container，在 container 中使用命令 `kubevpn connect`, 然后在 WSL
中使用 `kubevpn dev --network container:$CONTAINER_ID`
### 4，在使用 `kubevpn dev` 进入开发模式后，无法访问容器网络，出现错误 `172.17.0.1:443 connect refusued`，该如何解决？
答案：大概率是因为 k8s 容器网络和 docker 网络网段冲突了。
解决方案：
- 使用参数 `--connect-mode container` 在容器中链接，也可以解决此问题
- 可以修改文件 `~/.docker/daemon.json` 增加不冲突的网络，例如 `"bip": "172.15.0.1/24"`.
```shell
➜ ~ cat ~/.docker/daemon.json
{
"builder": {
"gc": {
"defaultKeepStorage": "20GB",
"enabled": true
}
},
"experimental": false,
"features": {
"buildkit": true
},
"insecure-registries": [
],
}
```
增加不冲突的网段
```shell
➜ ~ cat ~/.docker/daemon.json
{
"builder": {
"gc": {
"defaultKeepStorage": "20GB",
"enabled": true
}
},
"experimental": false,
"features": {
"buildkit": true
},
"insecure-registries": [
],
"bip": "172.15.0.1/24"
}
```
重启 docker，重新操作即可
