### 歡迎訪問我的GitHub
> 這裡分類和彙總了欣宸的全部原創(含配套原始碼)：[https://github.com/zq2599/blog_demos](https://github.com/zq2599/blog_demos)

### 本篇概覽
- 本文是《Kubernetes深入學習》系列的第二篇，上一章我們下載了Kubernetes1.13原始碼，然後修改kubectl原始碼再構建執行進行驗證，在整個原始碼包中，除了kubectl這樣的可執行程式，還有api-server、controller-manager這些docker容器，今天的實戰是修改這些容器映象的原始碼，再部署新的映象，驗證我們修改的程式碼是否生效；

### 環境資訊
- 為了驗證修改的結果在Kubernetes環境是否生效，需要您準備好Kubernetes1.13版本的環境，實戰中涉及的應用和版本資訊如下：
1. 作業系統：CentOS 7.6.1810
2. go版本：1.12
3. Docker：17.03.2-ce
4. Kubernetes：1.13

### 關於依賴映象的下載
- 在編譯過程中會用到以下三個映象，但是docker pull命令是無法下載到這些映象的（你懂的）：
1. k8s.gcr.io/kube-cross:v1.11.5-1
2. k8s.gcr.io/debian-iptables-amd64:v11.0
3. k8s.gcr.io/debian-base-amd64:0.4.0

- 如果您的環境無法下載這三個映象，可透過以下方式來下載：
- 執行以下命令，下載我上傳的三個映象：

```shell
docker pull bolingcavalry/kube-cross:v1.11.5-1 \
&& docker pull bolingcavalry/debian-iptables-amd64:v11.0 \
&& docker pull bolingcavalry/debian-base-amd64:0.4.0
```

- 下載完畢後，透過docker images命令可以看到這三個映象：

```shell
[root@hedy kubernetes]# docker images
REPOSITORY                            TAG                 IMAGE ID            CREATED             SIZE
bolingcavalry/kube-cross              v1.11.5-1           b16987a9b305        7 weeks ago         1.75 GB
bolingcavalry/debian-iptables-amd64   v11.0               48319fdf4d25        4 months ago        45.4 MB
bolingcavalry/debian-base-amd64       0.4.0               8021d54711e6        4 months ago        42.3 MB
```

- 執行以下命令，將下載的映象更名，並且刪除不再用到的映象：

```shell
docker tag b16987a9b305 k8s.gcr.io/kube-cross:v1.11.5-1 \
&& docker tag 48319fdf4d25 k8s.gcr.io/debian-iptables-amd64:v11.0 \
&& docker tag 8021d54711e6 k8s.gcr.io/debian-base-amd64:0.4.0 \
&& docker rmi bolingcavalry/kube-cross:v1.11.5-1 \
&& docker rmi bolingcavalry/debian-iptables-amd64:v11.0 \
&& docker rmi bolingcavalry/debian-base-amd64:0.4.0
```

- 此時再執行docker images檢視本地映象，可見正是編譯所需那三個：

```shell
[root@hedy kubernetes]# docker images
REPOSITORY                         TAG                 IMAGE ID            CREATED             SIZE
k8s.gcr.io/kube-cross              v1.11.5-1           b16987a9b305        7 weeks ago         1.75 GB
k8s.gcr.io/debian-iptables-amd64   v11.0               48319fdf4d25        4 months ago        45.4 MB
k8s.gcr.io/debian-base-amd64       0.4.0               8021d54711e6        4 months ago        42.3 MB
```

- 開啟檔案build/lib/release.sh，找到下面這段內容，將其中的**---pull**刪除，這樣就不會重新去遠端下載映象了：

```shell
"${DOCKER[@]}" build --pull -q -t "${docker_image_tag}" "${docker_build_path}" >/dev/null
```

- 這段程式碼的具體位置如下圖綠框所示，將綠框中的內容刪除：

![在這裡插入圖片描述](https://img-blog.csdnimg.cn/20190316190900723.jpg?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly94aW5jaGVuLmJsb2cuY3Nkbi5uZXQ=,size_16,color_FFFFFF,t_70)

- 至此準備工作已結束，接下來就是修改了；

### 修改原始碼
- 接下來的工作是修改原始碼，本次實戰要修改的是api-server的原始碼，我們在裡面加一些日誌，最後在驗證環節只要能看見這些日誌就說明我們修改的原始碼可以成功執行；
- 修改的檔案是create.go路徑如下，這個檔案是建立資源的響應入口：

```shell
$GOPATH/src/k8s.io/kubernetes/staging/src/k8s.io/apiserver/pkg/endpoints/handlers/create.go
```

- 在create.go處理請求的位置增加日誌程式碼，如下所示，所有fmt.Println的呼叫都是本次新增的內容：

```shell
func createHandler(r rest.NamedCreater, scope RequestScope, admit admission.Interface, includeName bool) http.HandlerFunc {
	return func(w http.ResponseWriter, req *http.Request) {
		fmt.Println("***********************************************************************************************")
		fmt.Println("start create", req)
		fmt.Println("-----------------------------------------------------------------------------------------------")
		fmt.Printf("%s\n", debug.Stack())
		fmt.Println("***********************************************************************************************")
```

- 上述程式碼的作用是在api-server接收到建立資源的請求時列印日誌，日誌內容是http請求內容和當前方法的呼叫堆疊列印出來；

### 開始構建
- 進入目錄$GOPATH/src/k8s.io/kubernetes，執行以下命令開始構建映象：

```shell
KUBE_BUILD_PLATFORMS=linux/amd64 KUBE_BUILD_CONFORMANCE=n KUBE_BUILD_HYPERKUBE=n make release-images
```

- 根據build/root/Makefile中的描述，KUBE_BUILD_CONFORMANCE引數用來控制是否建立一致性測試映象，KUBE_BUILD_HYPERKUBE控制是否建立hyperkube映象(各種工具整合在一起)，這兩個目前都用不上，因此是設定為"n"表示不構建；

- 大約10多分鐘後，映象構建成功，控制檯輸出如下：

```shell
[root@hedy kubernetes]# KUBE_BUILD_PLATFORMS=linux/amd64 KUBE_BUILD_CONFORMANCE=n KUBE_BUILD_HYPERKUBE=n make release-images

```

- 在目錄下可見構建的tar檔案，可以透過docker load命令載入到本地映象倉庫使用：

```shell
[root@hedy amd64]# cd $GOPATH/src/k8s.io/kubernetes/_output/release-images/amd64
[root@hedy amd64]# ls
cloud-controller-manager.tar  kube-apiserver.tar  kube-controller-manager.tar  kube-proxy.tar  kube-scheduler.tar
```
- 將新生成的kube-apiserver.tar上傳到kubernetes環境的master節點；
- 執行命令**docker load < kube-apiserver.tar**，將檔案kube-apiserver.tar匯入本地映象倉庫；
- 執行命令**docker images**，如下所示，可見本地倉庫多了個TAG為**v1.13.5-beta.0.7_6c1e64b94a3e11-dirty**的kube-apiserver映象：

```shell

```
- 先看看當前的api-server這個Pod的基本情況，命令是**kubectl describe pod kube-apiserver-master -n kube-system**，如下所示，當前的映象是**k8s.gcr.io/kube-apiserver:v1.13.0**：

```shell
[root@master 16]# kubectl describe pod kube-apiserver-master -n kube-system

```

- 修改檔案/etc/kubernetes/manifests/kube-apiserver.yaml，修改完畢後，執行命令**kubectl apply -f kube-apiserver.yaml**使修改生效；

### 驗證原始碼修改是否生效
- 執行命令**kubectl logs -f kube-apiserver-master -n kube-system**檢視Pod的日誌，內容如下，可見請求的詳細資訊已經列印出來了，證明之前修改的程式碼已經生效，這是個系統事件物件的建立請求：

```shell

- 接下來我們自己建立個rc資源試試，新開一個控制檯視窗連線Kubernetes的master，輸入以下命令建立一個名為nginx-rc.yaml的檔案，內容是nginx的rc：

```shell
tee nginx-rc.yaml < 818 [] false 192.168.182.130:6443 map[] map[] <nil> map[] 192.168.182.130:57856 /api/v1/namespaces/default/replicationcontrollers 0xc007b83600 <nil> <nil> 0xc004bc40f0}
