Retrieving the number of instances in an .erb template


Cyrille Le Clerc
 

Thanks Dmitriy,

I discussed with the Pivotal OpsManager team, I will use OpsManager's
capability to to inject the list of assigned IPs with ".ips" (1) and then
count the number of elements of this array.

I could also have used the ".instances" accessor but these IPs will help me
for other use cases.

Currently there is no way to do that unless you specify it as a property

Dear all,

I work on a boshrelease that can deploy 1..* Jenkins master and 1..*
Jenkins slaves. To dispatch the slaves between the master, I want to
implement a rule based on a modulus using the instance index and the total
number of instances.

I know how to retrieve the index of the instance in a .erb template with
<%= index %> (1)

How can I retrieve the total number of instances of a job?

Thanks for your help,

Cyrille
