Retrieving the number of instances in an .erb template
|
Cyrille Le Clerc
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 (1) https://github.com/cloudfoundry-community/bosh-gen/blob/master/lib/bosh/gen/generators/job_generator/templates/jobs/%25job_name%25_simple/templates/data/properties.sh.erb#L8 -- Cyrille Le Clerc email & gtalk : cleclerc(a)cloudbees.com / mob: +33-6.61.33.69.86 / skype: cyrille.leclerc CloudBees, Inc www.cloudbees.com <https://www.cloudbees.com/jenkins/juc-2015> <https://www.cloudbees.com/cdsummit-2015> |

Currently there is no way to do that unless you specify it as a property
and manually update it. This will be possible once we implement links: https://github.com/cloudfoundry/bosh-notes/blob/master/links.md On Mon, May 4, 2015 at 8:39 PM, Cyrille Le Clerc <cleclerc(a)cloudbees.com> wrote: Dear all, |

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.
