Deploy your first applicationΒΆ

In this guide we are going to deploy a simple application: cheese-deployent. This deployment defines 3 services with a 2 replication factor. Traefik will load balance the requests among the replicas in the Kubernetes nodes. For more details about the cheese deployment, please refer to:

Start by substituting domain_name with in cheese-deployent.yml (where is the domain that points to the edge nodes, through CloudFlare):

sed -i -e 's/domain_name/' examples/cheese-deployment.yml

Now, copy the cheese-deployent.yml file into the master node:

ansible master -m copy -a "src=examples/cheese-deployment.yml dest=/home/ubuntu"

Finally, deploy the application using kubectl:

ansible master -a "kubectl apply -f /home/ubuntu/cheese-deployment.yml"

If everything goes well you should see some front-ends and back-ends showing up in the Traefik UI, and you should be able to access the services at:

One simply and quick way to access the Traefik UI is to tunneling via ssh to one of the edge nodes with the following command:

ssh -N -f -L localhost:8080:localhost:8080 ubuntu@<edge1-floating-ip>
ssh -N -f -L localhost:8081:localhost:8081 ubuntu@<edge2-floating-ip>

If you are wondering how to get the edge-floating-ip, then open the inventory file which is created after having spun up the cluster in the KubeNow folder

By visitng for instance your localhost:8080 in your browser you should be displayed with the following UI:


where on the left highlighted in yellow you can find your deployed frontend apps whereas on the right highlighted in green the backend services are listed
