This repository contains an example project that can be built using the s2i-aspnet builder image, which can be used to create reproducible Docker images from your ASP.NET project’s source code. The resulting images can be run using Docker or deployed to OpenShift.
For more information about using these images with OpenShift, please see the official OpenShift Documentation.
The sample application can be built and run either within OpenShift or standalone by combining the application using s2i tool and running with existing image using Docker. The following sections describes these processes
After logging into an OpenShift environment and creating or using an existing project, create a new application which combines the ASP.NET S2I builder and the sample application from this repository
oc new-app registry.access.redhat.com/dotnet/dotnetcore-10-rhel7~https://github.com/redhat-developer/s2i-dotnetcore-ex --name=aspnet-app --context-dir=appCreate a new route so that the application is accessible outside the OpenShift environment
oc expose service aspnet-appThe application will now be available at http://aspnet-app-<project>.<default_subdomain>;
A template has been provided to simplify the build and deployment of a ASP.NET application on OpenShift. The template is located in the templates folder in a file called [aspnet-s2i-template.json](templates/aspnet-s2i-template.json).
After logging into an OpenShift environment and creating or using an existing project, add the template to the project
oc create -f templates/aspnet-s2i-template.json|
Note
|
Alternately, the template can be added to the |
Instantiate the template to build and deploy the sample application
oc new-app --template=aspnet-s2i -p GIT_URI=https://github.com/redhat-developer/s2i-dotnetcore-exThe template can also be instantiated using the OpenShift web console. Login to the console and navigate to the desired project. Click the Add to Project button. Search and select the aspnet-s2i.
Click Create to start a build and deploy the sample application.
Once the build has completed and the resulting container started, the application will be available at http://aspnet-app-<project>.<default_subdomain>;
To build a new ASP.NET application using a previously existing S2I builder, execute the following command:
git clone https://github.com/redhat-developer/s2i-dotnetcore-ex.git
cd s2i-dotnetcore-ex
s2i build app/ aspapp aspnet-app --loglevel=5The resulting image can be executed using docker:
docker run -t -p 5000:5000 aspnet-appOnce the container is running, it should be accessible using:
curl 127.0.0.1:5000The template has been configured with a liveness and readiness probe of which you can read more at https://docs.openshift.com/enterprise/latest/dev_guide/application_health.html. It checks if the container is healthy by doing a HTTP call to the root application. It checks if the application is ready by performing an HTTP call to /Home/About. If you’d like to see how the probe is working, just oc log -f <pod>.
