Lab 6

Automated car service deployment

Lab Goal

To leverage Ansible automation to deploy .Net web service in a container.

ARCHITECTURE

Deploy .Net web service in a container

WHERE ARE PLAYBOOKS?

• The travel backend services are deployed using Ansible playbooks
• They are found here:



• $ cd support/playbooks/deploy-ocp-services



• Let's deploy the car service:



• $ ./ansible-playbook-dotnetservice.sh

PLAYBOOK START

• The car service playbook stars with messages, setup and logging in to the OpenShift Container Platform:



• $ ./ansible-playbook-dotnetservice.sh

PLAYBOOK DEPLOYMENT

• The car service playbook finally deploys a new container, patches config to expose ports, exposes a service route and reports playbook status as it finishes:

IF BUILD FAILS

• The playbook can fail if adding .Net stream failed
• To determine cause, see the error message:

HOW TO FIX

For some reason the .Net stream was not added, do this by hand:

• $ oc login -u system:admin

• $ oc create -n openshift -f 'https://raw.githubusercontent.com/openshift/openshift-ansible/master/roles/openshift_examples/files/examples/latest/image-streams/dotnet_imagestreams.json'

Then run car service playbook again (or if build in OCP console failed, rebuild it):

• $ ./ansible-playbook-dotnetservice.sh

DEPLOYED CARS SERVICE

• When a build finishes you see a new deployment container appears in Monitoring view under Deployments:
