This repository gives you a quickstart into Apama development by providing a Visual Studio Code devcontainer environment for testing and deploying to your Cumulocity IoT Cloud tenant. In order to get started you can simply fork this repository and go through the instructions below.
- You need to "buy" the Apama docker (it is free with community edition, but you need to activate it for your docker account)
- In order to deploy to Cumulocity Cloud you need a tenant with subscribed Apama and Analytics Builder
- Ensure you are logged into your docker account inside Visual Studio Code when you build the devcontainer
Before you build the devcontainer within Visual Studio Code you should take a look at the devcontainer.json and adjust the build parameters and environment variables.
| Parameter | Description | Comments |
|---|---|---|
| APAMA_VERSION | the tag of the Apama base container | Please see docker hub for available versions |
| APAMA_ANALYTICS_BUILDER_SDK_BRANCH | the branch/version of the Analytics Builder SDK | Please see Github for the available branches |
| CUMULOCITY_SERVER_URL | The Cumulocity IoT instance to connect to | |
| CUMULOCITY_TENANT | The tenantId of your Cumulocity IoT tenant | |
| CUMULOCITY_USERNAME | The username of your Cumulocity IoT user | |
| CUMULOCITY_PASSWORD | The username of your Cumulocity IoT password | |
| CUMULOCITY_APPKEY | The application key the local Apama will use for testing |
Note:
The Analytics Builder SDK needs to be in the same version as the Apama in the Cloud when you want to deploy. Therefore it also recommended to use the same Apama version in the devcontainer (e.g. if the Cloud is in version 10.7 the same versions should be used in the devcontainer for both Apama and SDK).
After you finsihed the configuration you can click the devcontainer icon in the bottom left of Visual Studio Code and select Open Folder in Container....
Once the container has been built and started you should see four folders in your VCS workspace:
- Development (the contents of this repository)
- Analytics Builder SDK
- Analytics Builder SDK Documentation
- Apama
Please check the SDK documentation for more detailed instructions.
You can find an example pysys project under Development -> example. Simply navigate to the folder where the pysysproject.xml is located and run pysys test.
In order to deploy your blocks to your Cumulocity IoT tenant you can simply run apama blocks deploy <extensionName> from the folder where your blocks are located ( the .mon files). The extensionName can be freely chosen. You can try it out by navigating to Development -> example -> blocks and run the command from there.
In order to remove your blocks again from your Cumulocity IoT tenant just run apama blocks undeploy <extensionName>. The extensionName has to be the same as you used when deploying.
