Tool discovery in dockerized Pipelines

[SylivanKenobi]

If the pipeline runs in a docker container on a VM-Node the SharedLibrary can't find tools from inside the container because it only searches on the vm itself. In my Opinion this Method has to be extended to also search the PATH in the container.

As a workaround the path for the tool can be set manually:

environment {
  executable_kustomize_path = "/usr/local/bin"
}

Example Pipeline:

pipeline {
  agent {
    docker {
      image 'line/kubectl-kustomize'
      label 'docker'
    }
  }
  stages {
    stage('Test') {
      steps {
        kustomize("path/to/yamls")
      }
    }
  }
}
