a script to convert java properties into env vars instead of manually typing them, it takes into account arrays in keys. the output format is specifically useful for kubernetes yaml env object

javaPropsToK8sEnvArray.js

const convertJavaPropertiesToEnvVars = function(configs) {
  const configLines = configs.split('\n');
  let out = ''
  for (let idx in configLines) {
    const line = configLines[idx]
    const key = line.split('=')[0].toUpperCase()
      .replace(/\[/g, '.')
      .replace(/\]/g, '')
      .replace(/\./g, '_')
    const value = line.split('=')[1]
    out += `
  - name : ${key}
    value: "${value}"
  `
  }
  return out;
}

// example:
// use https://www.toyaml.com/index.html to convert yaml to key,val properties
const configs = `server.port=80
maestro.kafka.broker=10.11.7.31:9092
maestro.kafka.indexing_topic=maestro_index_requests
maestro.repositories[0].code=collab
maestro.failure_log.dir=\${user.home}/logs/maestro`

console.log(convertJavaPropertiesToEnvVars(configs))

// output:
/*

  value: 80
