.NET Core Docker Image
.NET Core versions currently provided are:
- 1.0 (RHEL 7, CentOS 7)
- 1.1 (RHEL 7)
- [RETIRED] 2.0 (RHEL 7, CentOS 7)
- 2.1 (RHEL 7, RHEL 8, CentOS 7)
- 2.2 (RHEL 7, CentOS 7)
$ git clone https://github.com/redhat-developer/s2i-dotnetcore.git $ sudo VERSIONS=2.2 ./build.sh
Note: to build RHEL 7 based images, you need to run the build on a properly subscribed RHEL 7 machine. On RHEL 8 systems, RHEL 8 images are built by default. On non-RHEL, building CentOS images is the default.
To override the default basis of the image, set IMAGE_OS to the desired base system, such as IMAGE_OS=CENTOS or IMAGE_OS=RHEL8.
The Red Hat documentation for .NET Core describes the steps to install the image streams.
This repo contains a bash script that performs these steps.
For example, to install the
rhel7 based images and add a secret for authenticating against the
$ wget https://raw.githubusercontent.com/redhat-developer/s2i-dotnetcore/master/install-imagestreams.sh $ chmod +x install-imagestreams.sh $ ./install-imagestreams.sh --os rhel7 -u <subscription_username> -p <subscription_password>
./install-imagestreams.sh --help for more information.
For information about usage of Docker image for .NET Core 1.1, see 1.1 usage documentation.
For information about usage of Docker image for .NET Core 1.0, see 1.0 usage documentation.
Image name structure
- Platform name: 'dotnetcore' for 1.x, 'dotnet' for 2.0+
- Platform version (without dots)
- Base image: 'rhel7' or 'centos7'
templates folder contains OpenShift templates. Some of these will be shipped with OpenShift.
Templates under the
templates/community folder are provided and maintained by the community.
They are not supported or kept up-to-date by the maintainers of this repository and may fail when
used with newer versions of .NET Core.
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.
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.
The dotnet-runtime-example template can be used to create a new .NET Core service in OpenShift. It is meant to serve as an example of how to create a 'chained build' where one image is used to build an application but the runtime image is used to deploy the application.
For more information on build chaining in OpenShift, please see this doc.
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.
Provides templates for deploying a persistent, or ephemeral NuGet Server on OpenShift. These templates use BaGet, an open-source NuGet server implementation. Source code for BaGet can be found at: https://github.com/loic-sharma/BaGet.git.
