App configuration - AWS SimSpace Weaver

App configuration

You specify the configuration of an app (app_config) as part of the configuration for its domain. All types of domains use these same app configuration properties.


    app_config:
      package: "s3://weaver-myproject-111122223333-us-west-2/MyViewApp.zip"
      launch_command: ["MyViewApp"]
      required_resource_units:
        compute: 1
Note

SimSpace Weaver app SDK version 1.12.x projects use separate buckets for the app .zip files and the schema:

  • weaver-lowercase-project-name-account-number-app-zips-region

  • weaver-lowercase-project-name-account-number-schemas-region

The package property specifies the S3 URI of a zip file in an S3 bucket. The zip file contains the app executable (also called a binary ) and any other resources that it needs (such as libraries). Each instance of the app executable runs in a Docker container on a worker.

The launch_command property specifies the name of the executable and any command-line options to run the app. The value of launch_command is an array. Each token of the entire launch command string is an element in the array.

Example

  • For the launch command: MyTestApp --option1 value1

  • Specify: launch_command: ["MyTestApp", "-option1", "value1"]

The required_resource_units property specifies the number of compute resource units that SimSpace Weaver should allocate to this app. A compute resource unit is a fixed amount of processing capacity (vCPU) and memory (RAM) on a worker. You can increase this value to increase the amount of computing power available to the app when it runs on a worker. There is a limited number of compute resource units on each worker.
