Errors when running setup_psc.sh

[Loic_Joachim]

When trying to run the shell script “setup_psc.sh” to setup a private endpoint between mongodb atlas and GCP I get the following errors:

root@UserPC:/home/username# sh setup_psc.sh
Updated property [core/project].

For the record this is the script:

#!/bin/bash

gcloud config set project projectName

for i in {0..49}

do

  gcloud compute addresses create endpointName-ip-$i --region=us-central1 --subnet=default

done

for i in {0..49}

do

  if [ $(gcloud compute addresses describe endpointName-ip-$i --region=us-central1 --format="value(status)") != "RESERVED" ]; then

    echo "endpointName-ip-$i is not RESERVED";

    exit 1;

  fi

done

for i in {0..49}

do

  gcloud compute forwarding-rules create endpointName-$i --region=us-central1 --network=default --address=endpointName-ip-$i --target-service-attachment=projects/p-xuggng5phsozafushbhsgaiz/regions/us-central1/serviceAttachments/sa-us-central1-621c96dcfcf5d71f84355fd6-$i

done

if [ $(gcloud compute forwarding-rules list --regions=us-central1 --format="csv[no-heading](name)" --filter="name:endpointName" | wc -l) -gt 50 ]; then

  echo "Project has too many forwarding rules that match prefix endpointName. Either delete the competing resources or choose another endpoint prefix."

  exit 2;

fi

gcloud compute forwarding-rules list --regions=us-central1 --format="json(IPAddress,name)" --filter="name:endpointName" > atlasEndpoints-endpointName.json

I am running this on Windows Subsystem for Linux - Ubuntu

Ok, so I did manage to get it working. There were 3 problems:

1. The WSL shell doesn’t seem to handle the for loop syntax for i in {0…49} so I changed it to be:
   for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

2. The Endpoint Name cannot have capital letters in it…

3. While making the JSON file the filter: --filter=“name:endpointName” was returning nothing so I removed it and manually checked the JSON file.

Also if you are developing on Windows don’t forget to convert your file to Unix format with dos2unix
