node {
    echo 'Results included as an inline comment exactly how they are returned as of Jenkins 2.121, with $BUILD_NUMBER = 1'
    echo 'No quotes, pipeline command in single quotes'
    sh 'echo $BUILD_NUMBER' // 1
    echo 'Double quotes are silently dropped'
    sh 'echo "$BUILD_NUMBER"' // 1
    echo 'Even escaped with a single backslash they are dropped'
    sh 'echo \"$BUILD_NUMBER\"' // 1
    echo 'Using two backslashes, the quotes are preserved'
    sh 'echo \\"$BUILD_NUMBER\\"' // "1"

Google Compute Engine NFS Container VM

This script creates a Container VM on Google Compute Engine running a NFS V4 server exposed on Port 2049 with the /exports directory mounted to a persistent disk. This means:

• If the NFS VM Crashes, the persistent disk will still hold the NFS Files
• The persistent disk can be snapshotted to backup NFS Files

To run:

tribou

gcloud container clusters create cluster-1  \
  --num-nodes 1                             \
  --disk-size 10                            \
  --machine-type f1-micro                   \
  --no-enable-cloud-logging                 \
  --no-enable-cloud-monitoring

# When it's done, your kubectl command should work
kubectl cluster-info
