Function Compute:Deploy a code package

Preparations

1. Create a code directory for tests and specify a name for the directory. In this example, mycode is used.

   • Linux and macOS

     Run the mkdir -p /tmp/mycode command to create the directory.

   • Windows

     Create a folder and name it mycode.

2. In the mycode directory, create the index.py file.

   The following code describes the file content.

   from emoji import emojize
   def handler(event, context):
       return emojize(":thumbs_up:")

Use pip to install dependencies and deploy code

Prerequisites

• Python 3 is installed on your on-premises machine, and you are granted the required permissions on pip3.

• A Python function is created in the Function Compute console. For more information, see Create an event function.

Procedure

1. Run the pip3 install emoji -t . command in the mycode directory to install the emoji dependency library to the current directory.

2. Package all files in the mycode directory.

   • Linux and macOS

     Go to the mycode directory and run the zip code.zip -r ./* command.

     Note

     Make sure that you have the read and write permissions on the directory.

   • Windows

     Go to the mycode directory, select all files, right-click the files, and then compress the files into a .zip file.

3. In the Function Compute console, find the function that you want to manage. In the upper-right corner of the function details page, click Upload Code and upload the .zip file that you prepared.

Use Serverless Devs to install dependencies and deploy projects

Before you start

• Install Serverless Devs and Docker

• Configure Serverless Devs

Procedure

1. Run the cd /tmp/mycode command to go to the mycode directory.

2. Create the s.yaml file.

   The following sample code provides an example of the file:

   edition: 3.0.0
   name: fcDeployApp
   access: "default"
   
   vars: # The global variables.
     region: "cn-hangzhou"
   
   resources:
     hello_world:
       component: fc3 # The name of the component.
       props:
         region: ${vars.region}             
         functionName: "emojipy"
         description: 'this is emoji'
         runtime: "python3"
         code: ./
         handler: index.handler
         memorySize: 128
         timeout: 30
         environmentVariables:
           PYTHONUSERBASE: /code/python         # Add environment variables to obtain dependencies.code.

3. Add the requirements.txt file.

   Edit the file based on the following code snippet:

   emoji==2.0.0

4. Run sudo s build --use-docker to install dependencies.

   After the execution is complete, the dependencies are installed to the ./python directory.

5. Run sudo s deploy to deploy the project.

   After the execution, you can deploy your function to Function Compute.
