How to minimize VMs used in cf/diego
Stanley Shen <meteorping@...>
Hello, all
By default, there are about 20 VMs will be used in cf/diego installation. I am trying to minimize the VM size. I tried to follow https://github.com/cloudfoundry-community/cf-boshworkspace but got some problem. I create an issue for it but got no response, is this still maintained? If there are any other documentation about it, or any experience on it?

Hi, Stanley,

If you're looking to reduce the Diego VM footprint in a dev deployment, you could consider using the 'colocated_vN' (N=1,2,3) jobs in the manifests generated by the spiff-based scripts in diego-release. They pack all the jobs in diego-release (and garden and etcd) onto a single VM, so you could deploy with 1 instance of colocated_z1 and 0 instances of all other jobs. If you need more container capacity in that deployment, you can then increase the instance count of the cell jobs from 0 (you will have one cell already via the existing colocated job instance). Also, as a warning, the Diego team doesn't regularly test the colocated-VM deployment configuration, so it's possible that it may accidentally break in the future (or even that it's broken now!). So I wouldn't recommend its use in a production deployment. I can't speak to the current state of colocatability of the jobs in cf-release, or to the status of the community cf-boshworkspace project. Best, Eric, CF Runtime Diego PM

When I read "decrease the VM size" I guess you might be using BOSH-lite.

Then you could be interested in switching to microPCF which has a smaller memory footprint. /Benjamin
