How to get status of Kaniko build

Question

After doing a Kaniko build to Openshift I notice that Jenkins displays the status as Success as long as nothing is wrong with the code itself in the Jenkinsfile.
However the after the Success message the build is still going on in Openshift and it could go wrong depending on the Dockerfile contexts etc.. How could I have Jenkins wait for the status of the build in Openshift and have it display its results in the Jenkins console?? Here is my code:

#!/usr/bin/env groovy
def projectProperties = [
  [$class: 'BuildDiscarderProperty',strategy: [$class: 'LogRotator', numToKeepStr: '5']]
]

    node {
withVault(configuration: [timeout: 60, vaultCredentialId: 'vault-approle-prd', vaultUrl: 'https://vault.example.redacted.com'], vaultSecrets: [[path: 'secrets/kaniko', secretValues: [[vaultKey: 'ghp_key']]]])
{
 sh 'echo $ghp_key > output.txt'
}
}

node  {
 GHP_KEY = readFile('output.txt').trim()
}
