Passing pipeline CFG as env variable in build environment

[adhikasp]

Is there any way to export the pipeline config defined by MPL to environment variable?

I have use case to enable/disable some auxilary service (like database, redis, kafka, etc) if we want to build apps that need them in testing phase. I want the apps to be able to parse the setting from env var and connect to the right port/db/whatever.

For now, I manually define the env var for each of the config. Something like this:

void injectIntegrationSettingToEnv(Map config) {
    env.'test_integration_postgresql_enabled' = config.test.integration.postgresql.enabled
    env.'test_integration_postgresql_username' = config.test.integration.postgresql.username
    env.'test_integration_postgresql_password' = config.test.integration.postgresql.password
    env.'test_integration_postgresql_database' = config.test.integration.postgresql.database
    env.'test_integration_postgresql_port' = config.test.integration.postgresql.port
    env.'test_integration_postgresql_host' = config.test.integration.postgresql.host
}

Hmmm, I think it's not a good idea to export the whole CFG, but you can get the map, stored in some variable inside CFG, for example:

• Deploy/Deploy.groovy

  CFG.'config.a' = 1
  CFG.'config.b' = 2
  MPLModule('Service Deploy', CFG)

• Deploy/ServiceDeploy.groovy:

  def config = CFG.config
  for( it in config ) {
    println("Item: ${it.key}, ${it.value}")
  }

• Output:

  Item: a, 1
  Item: b, 2

So you can get the map and iterate over it - just give the good name instead of config, combine the good env var and write it using writeFile to workspace.

Hopefully this will help)

Or you can define env from the for loop, just use env."prefix_${it.key}" = it.value - something like that.

Agree, I only needed subset of the CFG anyway.

Ended up this way. Thanks for the suggestion 😄
