Go

步骤一：准备环境

安装Funcraft，最简单的方式就是直接下载可执行的二进制文件。

1. 安装Funcraft到本机。详情请参见安装Funcraft。
2. 执行fun --version检查安装是否成功。
3. 执行fun config配置Funcraft。然后按照提示依次配置Account ID、Access Key ID、Access Key Secret、Default region name。

   fun config
   Aliyun Account ID 1234xxx
   Aliyun Access Key ID xxxx
   Aliyun Access Key Secret xxxx
   Default region name cn-xxxx
   The timeout in seconds for each SDK client invoking 300
   The maximum number of retries for each SDK client 5
   Allow to anonynously report usage statistics to improve the tool over time? (Y/n)

步骤二：部署和调用函数

1. 执行以下命令克隆示例工程到本地。

   git clone https://github.com/awesome-fc/fc-custom-demo          

   说明 如果您没有安装Git，可以直接在浏览器地址栏输入https://github.com/awesome-fc/fc-custom-demo，然后单击下载按钮直接下载。
2. 执行以下命令进入克隆的示例项目中。

   cd fc-custom-demo
   cd go-demo

3. 执行以下命令部署函数。

   make deploy

   返回结果如下。

   docker build -t fc-go-runtime  -f build-image/Dockerfile build-image
   Sending build context to Docker daemon  3.072kB
   Step 1/5 : FROM golang:1.12.16-stretch
    ---> 7ad03a8aece5
   ...
   Step 5/5 : RUN go get github.com/awesome-fc/golang-runtime
    ---> Using cache
    ---> 262e7f38ac05
   Successfully built 262e7f38ac05
   Successfully tagged fc-go-runtime:latest
   docker run -it -v $(pwd):/tmp fc-go-runtime bash -c "go build -o /tmp/code//bootstrap /tmp/code/main.go"
   chmod +x code/bootstrap
   fun deploy -y
   using template: template.yml
   ···
   Waiting for service go_demo to be deployed...
           Waiting for function fc_go to be deployed...
                   Waiting for packaging function fc_go code...
                   The function fc_go has been packaged. A total of 1 file were compressed and the final size was 3.76 MB
           function fc_go deploy success
   service go_demo deploy success

4. 执行以下命令调用部署的函数。

   fun invoke -e "Hello World"

   返回结果如下。

   ...
