+
+## 根据模板创建项目
+
+```sh
+# 登录openfaas
+faas-cli login https://gateway-openfaas.netwarps.com -p xxxx
+# 查看已经存在的function列表
+faas-cli list
+# 拉取语言模板
+faas-cli template pull
+# 根据默认go模板创建function项目
+faas-cli new -p registry.solarfs.io/go-test  go-test2 --lang go
+```
+
+生成如下一个目录一个yml文件
+
+```sh
+go-test2
+go-test2.yml
+```
+
+`go-test2.yml`如下
+
+```yaml
+version: 1.0
+provider:
+  name: openfaas
+  gateway: https://gateway-openfaas.netwarps.com
+functions:
+  go-test2:
+    lang: go

+    image: registry.solarfs.io/go-test/go-test2:latest
+    secrets: # 这个是手动添加的，配置镜像imagePullSecret
+     - registry-pld-cicd # imagePullSecret name
+```
+
+构建镜像
+
+```sh
+faas-cli build -f ./go-test.yml --build-arg GOPROXY=https://proxy.golang.com.cn,direct
+```
+
+登录私有镜像仓库
+
+```sh
+faas-cli registry-login --username user --password pass
+```
+
+推送镜像
+
+```sh
+faas-cli push -f ./go-test.yml
+```
+
+部署function
+
+```sh
+faas-cli deploy -f ./go-test.yml
+```
+
+查看部署详细信息
+
+```sh
+faas-cli describe go-test
+```
+
+测试
+
+```sh
+echo "test go"|faas-cli invoke  go-test
+```
+
+删除function
+
+```sh
+faas-cli remove go-test
+```
+
+## 思考
+
+### 减少代码量
+
+openfaas 如果想要减少代码量，就是自定义提前定义代码模板, 提前把封装好的 模块 或  公共函数，比如说 web route logging metrics utils  等 写成模板，这样其它项目就可以从模板生成，直接写需要的业务代码了。也可以找别人开源的 代码模板，有现成的也可以用。
+
+### 自动扩容
+
+openfaas 开源版本扩容最多只能扩到5，再高的话，要买企业版，这个不实用, 不如使用k8s hpa 或 keda  实现自动扩容

+#  使用playwright截图Kibana图表
+
+## 安装 playwright
+
+```sh
+pip install playwright
+```
+
+## 安装 playwright 依赖项
+
+```sh
+playwright install --with-deps
+```
+
+## 使用playwright自动生成代码
+
+使用`playwright` 生成访问`kibana dashboard` 代码，其中`--ignore-https-errors`为忽略证书认证
+
+```sh
+playwright codegen --ignore-https-errors "https://kibana.liujinye.example/"
+```
+
+上面命令执行完会自动调用 chromium ，并生成python 代码，如图：
+
+![image-20231221190033724](./images/image-20231221190033724.png)
+
+自动生成代码示例如下：
+
+```python
+from playwright.sync_api import Playwright, sync_playwright, expect
+
+
+def run(playwright: Playwright) -> None:
+    browser = playwright.chromium.launch(headless=False)
+    context = browser.new_context(ignore_https_errors=True)
+    page = context.new_page()
+    page.goto("https://kibana.liujinye.example/login?next=%2F")
+    page.get_by_label("用户名").click()
+    page.get_by_label("用户名").fill("elastic")
+    page.get_by_label("密码", exact=True).click()
+    page.get_by_label("密码", exact=True).fill("xxxxxxxxxxxxxxx")
+    page.get_by_text("欢迎使用 Elastic用户名密码登录").click()
+
+    # ---------------------
+    context.close()
+    browser.close()
+
+
+with sync_playwright() as playwright:
+    run(playwright)
+
+```
+
+在生成好的代码基础上增加一些其它逻辑
+
+```python
+from playwright.sync_api import Playwright, sync_playwright
+
+
+def run(playwright: Playwright) -> None:
+    browser = playwright.chromium.launch(
+        headless=False, # 本地调度不使用headless 自动打开浏览器界面,服务器设置为True 
+        args=['--start-maximized']
+    )
+    # 增加设置窗口大小
+    context = browser.new_context(ignore_https_errors=True,viewport={'width': 1792, 'height': 1120})
+    page = context.new_page()
+    page.goto("https://kibana.liujinye.example/")
+    page.get_by_label("用户名").fill("elastic")
+    page.get_by_label("密码", exact=True).fill("xxxxxxxxxxxx")
+    page.get_by_role("button", name="登录").click()
+    # 增加等待页面加载超时时间
+    page.wait_for_timeout(5000)
+
+	  # 在浏览器中输入要请求的dashboard
+    page.goto("https://kibana.liujinye.example/app/dashboards#/view/c95bd6e0-7a22-11ee-8b13-0f9a027c16f6?_g=(refreshInterval%3A(pause%3A!t%2Cvalue%3A60000)%2Ctime%3A(from%3Anow-7d%2Fd%2Cto%3Anow))")
+    # 增加等待页面加载超时时间
+    page.wait_for_timeout(10000)
+    # 添加的截图代码
+    page.screenshot(path=f'example.png', full_page=True)
+
+    context.close()
+    browser.close()
+
+
+with sync_playwright() as playwright:
+    run(playwright)
+
+```
+
+## Dockerfile示例
+
+```dockerfile
