Reusing VM App configurations with DHCP IP addresses
Sorry if this is obvious, new to CloudShell.
Scenerio:
1. Build a Blueprint with VM Apps using VxLAN networks and DHCP. The connectivity between Apps is provided by SDN network overlay technology and virtual network switches and such (VLAN Auto), etc.
2. IP addresses are generated automatically using DHCP provided on each virtual network subnet. Naturally, these IP addresses can/will change with each reservation of the Blueprint.
3. App VM configurations, such as network configurations on these virtual devices have to be added to the configurations, including IP addresses to connected devices. An example is a load balancer has the configuration of the Servers being load balanced.
Question:
How can this configuration be reused again and again? This must be a common scenario and I am looking for common solutions or approaches. Changing IP addresses within the running App causes CloudShell to loose connectivity and such.
Hi Keith,
It looks like you want to have a scenario in which a Configuration script is re-used for multiple scenarios with dynamic IP Addresses?
The way to achieve this is by having the IP Addresses be an input parameter to the configuration script, and edit the input parameters of the app during the configuration phase, before running the configuration (this can be achieved by customizing the setup script for that blueprint.)
Our Dev guide has some examples for this exact scenario:
https://devguide.quali.com/orchestration/9.0.0/common-orchestration-recipes.html
(Check out the "Configuring Apps in a Sandbox" section)
you can have this happen during the configuration phase of the default setup by registering the default setup workflow with enable_configuration=False, and then use "add_to_configuration" to put your own configuration logic function as the configuration phase.
