Farmer is an open source, free to use .NET domain-specific-language (DSL) for rapidly generating non-complex Azure Resource Manager (ARM) templates.
For those of you working with Azure today, you may already be aware that one of the most useful features is the ability to generate entire infrastructure architectures as code via ARM Template files. These templates contain a declarative model that allows repeatable deployments and idempotent releases (among other things).
Unfortunately, ARM templates have some limitations caused by the fact that they must be authored in a verbose JSON dialect:
In other words, whilst working with ARM templates that have already been created is relatively straightforward, the authoring of the templates themselves is time-consuming and error-prone.
Whilst there have been some recent improvements to ARM - including tooling improvements in VS Code through an extension - we think that we can do much better than relying on tooling for a specific IDE, which means using something different than JSON when directly authoring ARM templates.
Farmer templates are simple .NET Core applications which reference the Farmer NuGet package. This package contains a set of types that model Azure resources in a strongly-typed and succinct fashion, as well as functionality to create ARM templates from this model - and even deploy directly to Azure.
Farmer currently has support for a large number of common resources including web apps, sql and storage, with more being added over time.
