I was recently asked how to determine how many application instances exist in a given ORG at a point in time. The script below can do this using CF CURL command which means you must be logged into your Pivotal Cloud Foundry instance for this to work. You can use the CF REST API itself but I find the CF CURL much easier.
CF REST API https://apidocs.cloudfoundry.org/249/
The script below is assuming an ORG name of "apples-pivotal-org" so it would make sense to pass this in as a script variable which is easy enough to do
Prior to running this script it's worth checking your current TARGET endpoints as shown below.
pasapicella@pas-macbook:~/pivotal/PCF/scripts$ cf target
API endpoint: https://api.run.pivotal.io (API version: 2.65.0)
User: papicella@pivotal.io
Org: apples-pivotal-org
Space: development
Script:
echo "AI Count for applications in a organization.."
echo ""
guids=$(cf curl /v2/apps?q=organization_guid:`cf org apples-pivotal-org --guid` | jq -r ".resources[].metadata.guid")
total=0
for guid in $guids; do
name=$(cf curl /v2/apps/$guid | jq -r ".entity.name")
count=$(cf curl /v2/apps/$guid | jq -r ".entity.instances")
echo -e "App Name: $name , Instances: $count"
total=$(( $total + $count ))
done
echo "-----"
echo "Total AI's = $total"
echo ""
Output:
pasapicella@pas-macbook:~/pivotal/PCF/scripts$ ./ai-count-org-details.sh
AI Count for applications in a organization..
