Error message

Please config the <image> of <runtime> in pom.xml.

What it means

Raised by AzureFunctionsDeployCommand.validateParameters when the runtime OS is set to docker but no container image is configured. Docker-based Azure Function deployment requires the image to deploy (configured via the runtime image setting in the azure-functions plugin configuration), and validation refuses to continue because the Azure Function App would have nothing to run.

Solutions

1. Configure the container image for the docker runtime in the azure-functions plugin configuration (runtime/image setting)
2. Build and push the container image to a registry accessible by Azure before deploying
3. Switch the OS setting to linux if a container deployment was not intended
