OpenShift Templates

The templates folder contains OpenShift templates. Some of these will be shipped with OpenShift. If a template is not on your OpenShift installation, you can import it:

oc create -f <template.json>

To instantiate a template you can use the oc new-app command:

oc new-app --template=<template>

The 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 desired template by it's name (e.g. dotnet-example). Next, click Create to start a build and deploy the sample application. Once the build has and deployment have completed, you can browse to the application using the url you find in project overview.

dotnet-example

The dotnet-example template can be used to create a new .NET Core service in OpenShift. It provides parameters for all the environment variables of the s2i-dotnetcore builder. It also includes a liveness and a readiness probe.

dotnet-pgsql-persistent

The dotnet-pgsql-persistent creates a .NET Core service with a PostgreSQL backend. It provides parameters for all the environment variables of the s2i-dotnetcore builder and variables to setup the database. The database connection information is passed to the .NET application via the ConnectionString environment variable.
