If we have the Vnet already created and we need to add NSG and UDR to it can we do it using a new main.bicep file and can it reference the already created resources using existing while not using the same main.bicep file that was used to create vnets

You can call/name your bicep files anything that is useful, they do not have to be called main.bicep

if you follow a folder naming structure for different resource types, it's simple enough to use a main.bicep as the entry point to deploy those resource types, however it's just a simple convention, not a requirement.

I would recommend to maintain the configuration for your VNET/Subnets in a single place and then also only deploy it in a single place.

An ideal place for that VNET//Subnet configuration is in a Parameter file that you use as part of your deployment and is also checked into source control.

When you need to either add new subnets or modify NSG's or Route tables on the VNET, simply update the parameter file and then redeploy the VNET, which will also include ALL subnet information. So long as you don't make manual changes to your VNET/Subnet then by following this pattern you will always have a single source of truth to define the configuration, you can roll back to previous configurations via source control (if that was ever required) and you can view change history of the Parameter File over time.

If you have different Environments e.g. resource groups, then you will have different Parameter files that represent/reflect those VNET and other configurations. So in that way you can maintain a different set of NSG/RT subnets settings in different files across different VNETS in different resource groups etc.

If you have any more specific examples, please feel free to share.

thanks, @brwilkinson I really appreciate your help I am new to GitHub and coding or IaC, in general, though doing IT for the last 13 years and I am enjoying the new learnings .... hey do you offer help for private projects ?? I saw on one of the slides of ADF

[brwilkinson]

hey @say2merohit welcome to the world of IaC, it's a fun place and I believe truly worth the effort in the beginning to produce a much higher quality product in the end, when it comes to IT services ✅

I think Bicep is a great place to start and the language and tooling is only going to get better and become more helpful/useful over time.

My day job is within Microsoft Commerical Services, so I work with organizations with a support agreement with Microsoft to assist them on Automation projects and mostly moving to the cloud and standing up cloud services.

I am happy to be able to contribute back to the community and also be a part of Open source in general. I learn the most from working with others. Obviously, time is limited, so (unless it's part of my day job) I do like being able to work on public repos where the community can share ideas and we all learn from each other.

[say2merohit]

Wow thank you so much I am honored that you shared your experience with us, currently, I am looking at the blueprint ADF and trying to learn as much as I can, I am in a good position and probably can ask for Microsoft support agreement and see I can work with you officially ...but for the moment I am going to stay in this zone where every day I am creating and deleting code in my head and trying to build a solution based off what I have learned so far ... Thanks again for the help much appreciated !!

[brwilkinson]

Yeah definitely check out the great Learn content here:
