Initial implementation of Course registration service

[ratanparai]

Initial implementation of course registration service with one command and query

Command: SubmitCourseRequestCommand
Query: GetAllCourseRequestQuery

Currently, we do not need any authorization checks.

Moving this issue to Backlog. Will move it to respective milestone after confirmation from @mahedee

@ratanparai , what would be the service name? "CourseRegistration" is OK?

[ratanparai]

Yes, that will be perfect 👍

Whenever I am going to run migration command, I get following error. Could you please tell me what is the problem?

PS D:\Project\Github\eSchool\src\Services\CourseRegistration\CourseRegistration.Infrastructure> dotnet ef migrations add initmig --startup-project ../CourseRegistration.API

Could not execute because the specified command or file was not found.
Possible reasons for this include:

• You misspelled a built-in dotnet command.
• You intended to execute a .NET program, but dotnet-ef does not exist.
• You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

@mahedee You need to install the Entity Framework global tool by running -

dotnet tool install --global dotnet-ef

Doesn't show courseregistration.api to jaeger UI. I have already given a pull request. Could you please help me what is the problem?

@mahedee: Okay I will check the service.

You need to send request to the course registration service to show it in the Jaegar UI

How to send request? On which code block?

[ratanparai]

@mahedee: You need to add OpenTelemetry configuration in your service configuration, This is the configuration for Enrolling service -

"OpenTelemetry": {
  "Enabled": true,
  "Istio": false,
  "Jaeger": {
    "Enabled": true,
    "ServiceName": "enrolling.api",
    "Host": "jaeger",
    "Port": 6831
  }
}

You need to change the ServiceName and use the configuration in your service's appsettings.json file. For example -

"OpenTelemetry": {
  "Enabled": true,
  "Istio": false,
  "Jaeger": {
    "Enabled": true,
    "ServiceName": "courseregistration.api",
    "Host": "jaeger",
    "Port": 6831
  }
}

Also, to send request to your service, open your application's Swagger URL (from your code, I can see the URL is http://localhost:5103/swagger/index.html) and send any request to any API endpoints you have created. You can also use Postman too if you are comfortable with it.

CourseRegistration doesn't show in Banana Cake Pop. I mean graphql. I was trying using this url http://localhost:5101/graphql/
I have already given a pull request. Please review my code, what is the problem?

[ratanparai]

@mahedee: You mean the GraphQL API Gateway right?

I can see the CourseRegistration service in the API Gateway. You need to reload the schema.
