AutofacCloudFoundry - ASP.NET 4.x Sample Application

ASP.NET 4.x sample app built using the Autofac IOC container and illustrating how to use Config Server for Pivotal Cloud Foundry as a configuration source.

Pre-requisites

  1. Installed Pivotal CloudFoundry with Windows support
  2. Installed Spring Cloud Services
  3. Visual Studio 2017

Setup Config Server

You must first create an instance of the Config Server service in a org/space.

  1. cf target -o myorg -s development
  2. cd src\AspDotNet4\AutofacCloudFoundry
  3. cf create-service p-config-server standard myConfigServer -c ./config-server.json
  4. Wait for service to be available. (e.g. cf services)

Publish App & Push

  1. Open src\AspDotNet4\Configuration.sln in Visual Studio.
  2. Select AutofacCloudFoundry project in Solution Explorer.
  3. Right-click and select Publish
  4. Publish the App to a folder. (e.g. c:\publish)
  5. cd publish_folder (e.g. cd c:\publish)
  6. cf push

What to expect

The cf push will create an app in the space by the name foo and will bind the myConfigServer service instance to the app. You can hit the app @ http://foo.x.y.z/.

The Config Servers Git repository has been set to: https://github.com/spring-cloud-samples/config-repo

Use the menus at the top of the app to see various output:

  • CloudFoundry Settings - should show VCAP_APPLICATION and VCAP_SERVICES configuration data.
  • Config Server Settings - should show the settings used by the client when communicating to the config server. These have been picked up from the service binding.
  • Config Server Data - this is the configuration data returned from the Config Servers Git Repo. It will be some of the data from foo.properties, foo-development.properties and application.yml found in the Git repo.
  • Reload - will cause a reload of the configuration data from the server.

Observe Logs

To see the logs as you startup and use the app: cf logs foo

You should see something like this during startup:
