Open Source PAAs Scenario: Deploy Cloudfoundry (iii) deployment on OpenStack Bosh

Bosh is an automated tool provided by Cloudfoundry to install deployment and upgrade Cloudfoundry, but is part of the cloudfoundry. Generally speaking, Bosh is a client/server structure, Bosh client is called Bosh Cli,bosh server driven by Bosh and other components, see HTTP// docs.cloudfoundry.org/bosh/

The complete Bosh is a distributed environment, this article in order to simplify the installation of Bosh, Bosh all the components installed on a virtual machine, Bosh this way of deployment is called Microbosh.

Describes the deployment of the Bosh client in a CentOS environment and the deployment of the Microbosh tool on an OpenStack environment.

Here's a brief look at what this deployment file means
* Network describes the properties of the network in OpenStack
In the author's OpenStack environment, the network is OpenStack neutron networks, so the intranet uses DHCP to obtain the IP, so the type is dynamic. The net_id in Cloud_properties is an intranet address that can use DHCP to obtain IP, which can be obtained using neutron net-list

In order to be able to access the Microbosh from the extranet, we need to specify a floating IP for Bosh director, Bosh will automatically associate this IP to Bosh director

* Resource describes how much resources are allocated for the Micro Bosh Director, Instance_type defines the OpenStack Flavor,persistent_disk for this virtual machine defines the permanent disks that are attached to this virtual machine

* Cloud describes how to access OpenStack, where most of the content can be found in the Keystonerc_demo generated by the installation,

* Apply_spec defines the properties of the Micro Bosh, which we only need to modify one, that is, the time server address <NTP server IP>, for example, modified to time.asia.apple.com
