.NET Core Sample App for OpenShift

This repository contains an example .NET Core application that can be deployed on OpenShift.

The example is a simple CRUD web application that persists information in a database.

The example is meant to be built and run with the s2i-dotnetcore builder images. The branches of this repository correspond to versions of the s2i-dotnetcore images.

Deploying the application

You can deploy the application using the OpenShift client (oc) with the following commands:

# Make sure .NET image stream is available
oc describe is dotnet

## If not presented, install it.
oc create -f https://raw.githubusercontent.com/redhat-developer/s2i-dotnetcore/main/dotnet_imagestreams.json

# Create a new OpenShift project
$ oc new-project mydemo

# Add the database
$ oc new-app postgresql-ephemeral

# Add the .NET Core application
$ oc new-app dotnet:8.0-ubi8~https://github.com/redhat-developer/s2i-dotnetcore-persistent-ex#dotnet-8.0 --context-dir app

# Add envvars from the the postgresql secret, and database service name envvar.
$ oc set env dc/s2i-dotnetcore-persistent-ex --from=secret/postgresql -e database-service=postgresql

# Make the .NET Core application accessible externally and show the url
$ oc expose service s2i-dotnetcore-persistent-ex
$ oc get route s2i-dotnetcore-persistent-ex
