How to build

  1. Download and install JDK 17
  2. Export github personal access token & user name as environment variables.
        export packagePAT=<Token>
        export packageUser=<username>
  3. (optional) Specify the Java home path for JDK 17 ie;
        export JAVA_HOME=/Library/Java/JavaVirtualMachines/adoptopenjdk-17.jdk/Contents/Home/
  4. Install Docker
  5. Get a clone or download the source from this repository (https://github.com/ballerina-platform/module-ballerina-c2c)
  6. Run the Gradle command gradle build from within the module-ballerina-c2c directory.
  7. Copy c2c-extension/build/c2c-extension-***.jar file to <BALLERINA_HOME>/bre/lib directory.
  8. Copy c2c-ballerina/build/target/c2c-ballerina-zip/bala/ballerina/cloud directory to <BALLERINA_HOME>/repo/bala/ballerina directory.
  9. Copy c2c-ballerina/build/target/c2c-ballerina-zip/cache/ballerina/cloud directory to <BALLERINA_HOME>/repo/cache/ballerina directory.

Enabling debug logs

  • Use the "BAL_DOCKER_DEBUG=true" environment variable to enable docker related debug logs when building the ballerina source(s).
  • Use the "BAL_KUBERNETES_DEBUG=true" environment variable to enable kubernetes related debug logs when building the ballerina source(s).

Usage Sample:

import ballerina/http;
import ballerina/log;

listener http:Listener helloEP = new(9090);

service /helloWorld on helloEP {
    resource function get sayHello() returns string {
        return "Hello, World from service helloWorld ! ";
    }
}

Build the program with --cloud=k8s or --cloud=docker build option.

$ bal build --cloud=k8s <source_file>.bal 

The Kubernetes and Docker artifacts will be created in following structure.

$> tree
├── docker
│   └── Dockerfile
|-kubernetes
    └── hello-world.yaml
