Question

I added this to the `yml` file for the environment ```RwbPulumiProject ApplicationName rwb``` Apparently each setting key must be of the form `a b` The documentation page implies that the first bit is not required but apparently this is untrue Then I try to use it ``` Config config = new Pulumi Config string applicationName = config Require RwbPulumiProject ApplicationName ``` Is is possible to rename the class from `MyStack` My really makes my skin crawl But then ```C Work Azure RwbPulumiProject gt pulumi up Previewing update dev View Live Type Name Plan Info + pulumi pulumi Stack RwbPulumiProject dev create 1 error Diagnostics pulumi pulumi Stack RwbPulumiProject dev error Running program C Work Azure RwbPulumiProject bin Debug netcoreapp3 1 RwbPulumiProject dll failed with an unhandled exception System Reflection TargetInvocationException Exception has been thrown by the target of an invocation at object RuntimeTypeHandle CreateInstance RuntimeType type bool publicOnly bool wrapExceptions ref bool canBeCached ref RuntimeMethodHandleInternal ctor ref bool hasNoDefaultCtor at object RuntimeType CreateInstanceDefaultCtorSlow bool publicOnly bool wrapExceptions bool fillCache at object RuntimeType CreateInstanceDefaultCtor bool publicOnly bool skipCheckThis bool fillCache bool wrapExceptions at T Activator CreateInstance lt T gt at Task lt int gt Pulumi Deployment+Runner Pulumi IRunner RunAsync lt TStack gt IServiceProvider serviceProvider + = gt at Task lt int gt Pulumi Deployment+Runner RunAsync lt TStack gt Func lt TStack gt stackFactory gt Pulumi Config+ConfigMissingException Missing Required configuration variable RwbPulumiProject RwbPulumiProject ApplicationName please set a value using the command `pulumi config set RwbPulumiProject RwbPulumiProject ApplicationName lt value gt ` at string Pulumi Config RequireImpl string key string use string insteadOf at string Pulumi Config Require string key at new MyStack in C Work Azure RwbPulumiProject MyStack cs line 17 End of inner exception stack trace C Work Azure RwbPulumiProject gt ```

< stocky butcher 62635> the error is in the output your config is reading ```string applicationName = config Require RwbPulumiProject ApplicationName ``` which means it needs to be set as ```pulumi config set RwbPulumiProject RwbPulumiProject ApplicationName``` If you change your code to ```string applicationName = config Require ApplicationName ``` it should work

It s better to set the config values with the `pulumi config set` terminal command versus writing them in the YAML file directly it s of the form `pulumi config set lt key gt lt value gt ` So for your example you would run `pulumi config set azure native location uksouth` as an example <https github com pulumi examples tree 258d3bad0a00020704743e37911c51be63c06bb4 azure cs synapse running the app|here s how someone set up an Azure Native C Pulumi program>

but I can t read that value because it s not in the namespace of the project

great-queen-39697 · Answer

You can set it in the YAML file but the command line call ensures that it s formatted as expected which is why I recommend it In terms of not being able to read the value how are you calling it
