Change upstream service urls based on different environments

[rahulballal]

I would like to be able to change the upstream openapi source url via an environment variable or similar. For example in .meshrc file

In staging environment
https://products.acme.staging.com

switches to the following in production
https://api.acme.com/products

Do I have to rebuild the mesh app each time the rc file changes?

Thanks in advance and apologies if this has already been answered.

Are you talking about source or baseUrl?
source is the path to the OpenAPI schema while baseUrl is the URL of the API that would receive the HTTP requests on runtime.

sources:
  - name: Books
    handler:
      openapi:
        baseUrl: {VARIABLE_BASE_URL_PER_ENVIRONMENT}
        source: {VARIABLE_SCHEMA_URL_PER_ENVIRONMENT}

Thanks for responding @ardatan . Above is what I intended to ask. Sorry for not being thorough in the first go

You cannot change the schema (source) once it is built with mesh build but baseUrl can depend on an env variable like {env.ENV_VAR_NAME}. So you have to rebuild the project after source changes but you don't need to for baseUrl.
