Sample - Python Matplot

Install a custom layer in AosCloud.

Prerequisites​

  • Tools: AosCore SDK, Bash, Wget, Python and a virtual environment (venv) are installed.

Source Code​

You can explore the example by checking out the source code.

Install Additional Layer​

If your implementation requires packages or libraries that are not present in the system, you can install them separately as an additional layer.

  1. Create a custom layer. You can find detailed instructions on how to create a custom layer.

  2. Upload the layer to the cloud using aos-signer util.

  3. Use the service codename to add it as a dependency for your service.

    Example (Layer Details in AosCloud):

    Layer codename example

Prepare service for upload​

Before signing and uploading your service to AosCloud, review the root config.yaml file and make sure the layer dependency is configured.

nano ./config.yaml

Example config.yaml:

schemaVersion: 2
items:
  - identity:
      codename: "matplot-demo-service"
    dependencies:
      - identity:
          codename: matpotlib
          type: layer
        versions: "1.0.0"
    configuration:
      workingDir: /
    images:
      - archInfo:
          architecture: amd64
        cmd: /usr/bin/env HOME=/ /usr/bin/python3 -u matplot.py
        sourceFolder: x86
    sourceFolder: service1
publish:
  tlsKey: aos-user-sp.p12

Update the layer identity/version and service metadata as needed for your environment.

Upload service to AosCloud​

From the matplot directory, run:

<host>:~/demo-services/matplot$ aos-signer go
Starting DEPLOYMENT BUNDLE SIGNING process...
Starting CONFIG VALIDATION process...
Validating config...           VALID

Deployment bundle successfully uploaded!

Confirm​

  1. For detailed instructions on working with logs, see Get service logs.

  2. Open the log files in a text editor and search for the message "Plot has been successfully created.".

If the message is found, the service is working correctly.
