Use with minishift on all three major operating systems

This demo was developed using minishift on MacOS.

You can use Windows, MacOS or Linux to run this demo; Instructions are included for Linux-based operating systems.

Install minishift

You can get minishift at the minishift releases page:
https://github.com/minishift/minishift/releases

Start minishift

After installing minishift, and after making sure it is in your PATH, start it by running:
minishift start

Point the docker environment to be inside your minishift instance:
eval $(minishift docker-env)

Install .NET on your machine

Follow instructions at http://dot.net

Clone this repository to your machine

git clone https://github.com/redhat-dotnet-msa/dotnet-msa.git

Move into the directory

cd /dotnet_msa

Verify that the code runs on your machine

dotnet run

On your machine, point your browser to http://localhost:5000

Run in docker

Now that we know it runs, we need to publish a Release version to be used in docker.

Publish the solution:

dotnet publish -c Release -r rhel.7.4-x64

Then build the docker image

docker build -t dotnethello .

Test the docker image

docker run -d -p 5000:5000 --name dotnethello dotnethello

open https://$(minishift ip):5000

docker stop dotnethello

docker rm dotnethello

Using OpenShift/kubernetes

oc login $(minishift ip):8443 -u openshift-dev -p devel

Create the new project

oc new-project mydotnet

Run script to create new service

./create_green_1.sh1

Expose the service (i.e. give it a URI)

oc expose service dotnethello

On the host machine, log in to OpenShift at
open https://$(minishift ip):8443
user: openshift-dev
password: devel

You can view the service running.

Blue/Green Release

./create_blue_2.sh

Canary

First create the non-canary service deployment

canary_create_1.sh

Then create the canary service deployment

canary_create_2.sh

After that use the OpenShift console to "Up" and "Down" to get the mix right
