Step 1: Prepare the environment

An easy and simple way to install Funcraft is to download the executable binary files.

1. Install Funcraft on the local machine. For more information, see installation instructions.
2. Run fun --version to check whether the installation is successful.
3. Run fun config to configure Funcraft. Then configure Account ID, Access Key ID, Access Key Secret, and Default region name as prompted.

   $ 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)

Step 2: Deploy and call a function

1. Run the following command to clone the sample project to your local machine.

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

   Note If you do not have git installed, enter https://github.com/awesome-fc/fc-custom-demo in the address bar of your browser. Click the download button to download directly.
2. Run the following command to access the cloned sample project:

   cd fc-custom-demo
   cd go-demo

3. Run the following command to deploy the function:

   make deploy

   The following result is returned:

   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

   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. Run the following command to call the deployed function:

   fun invoke -e "Hello World"

   The following result is returned:
