PAS and PKS Deployments with Ops Manager
Page last updated:
Ops Manager is a web app that you use to deploy and manage Pivotal Application Service (PAS) and Pivotal Container Service (PKS). This topic explains why Pivotal recommends using separate installations of Ops Manager for PAS and PKS.
For more information about deploying PKS, see Installing PKS.
Ops Manager deploys the PAS and PKS runtime platforms using BOSH. For security reasons, Pivotal does not recommend installing PAS and PKS on the same Ops Manager instance. For even stronger security, Pivotal recommends deploying each Ops Manager instance using a unique cloud provider account.
Separate installations of Ops Manager allow you to customize and troubleshoot runtime tiles independently. You may choose to configure Ops Manager with different settings for your PAS and PKS deployments.
For example, PKS and many PAS features depend on BOSH DNS. If you deploy PAS to a separate Ops Manager instance, you can disable BOSH DNS for troubleshooting purposes in Ops Manager v2.2 and earlier. PAS can run without BOSH DNS, but key features such as secure service credentials with CredHub, service discovery for container-to-container networking, and NSX-T integration do not work when BOSH DNS is disabled.
If you deploy PAS and PKS to the same Ops Manager instance, you cannot disable BOSH DNS without breaking your PKS installation along with the PAS features that depend on BOSH DNS.
