Using SSL in your application

In this exercise you will set up your application to encrypt traffic with the OpenShift Wildcard certificate.

Step 1: Switch to an existing project

For this exercise, we will use an application that we created before. We will be using the binarydeploy-UserName that you created in the previous labs. Make sure you are switched to that project by using the oc project command. Remember to substitute UserName.

$ oc project binarydeploy-UserName

Step 2: View the routing config

To view the routing config you will need to use the oc get route command

$ oc get route/myapp -o yaml

apiVersion: v1
kind: Route
metadata:
  annotations:
    openshift.io/host.generated: "true"
  creationTimestamp: 2018-04-09T15:40:04Z
  labels:
    app: myapp
  name: myapp
  namespace: jimgarrett
  resourceVersion: "127925718"
  selfLink: /oapi/v1/namespaces/jimgarrett/routes/myapp
  uid: 45bc5aec-3c0c-11e8-888a-02722ccca8d2
spec:
  host: myapp-jimgarrett.apps.rhpds.openshift.opentlc.com
  port:
    targetPort: 8080-tcp
  to:
    kind: Service
    name: myapp
    weight: 100
  wildcardPolicy: None
status:
  ingress:
  - conditions:
    - lastTransitionTime: 2018-04-09T15:40:04Z
      status: "True"
      type: Admitted
    host: myapp-jimgarrett.apps.rhpds.openshift.opentlc.com
    routerName: router
    wildcardPolicy: None

Note here that the host: is set to the FQDN that your application is running on.

Currently the routing component of OpenShift 3 supports ports 80 and 443. When you first create your route, the mapping of 80 to your pod is done automatically. There are a few things that need to be done in order to get the 443 mapping to work.

Step 3: TLS Edge Termination

OpenShift has a wildcard SSL certificate that it can use for any application. We can use this SSL certificate to serve SSL from our application without having to generate a cert of our own (which is sometimes called SSL-offloading).

Edit your routing configuration:

oc edit route/myapp

You are going to add tls: termination: edge right below the host: section. It should look something like this.

apiVersion: v1
kind: Route
metadata:
  annotations:
    openshift.io/host.generated: "true"
  creationTimestamp: 2018-04-09T15:40:04Z
  labels:
    app: myapp
  name: myapp
  namespace: jimgarrett
  resourceVersion: "127925718"
  selfLink: /oapi/v1/namespaces/jimgarrett/routes/myapp
  uid: 45bc5aec-3c0c-11e8-888a-02722ccca8d2
spec:
  host: myapp-jimgarrett.apps.rhpds.openshift.opentlc.com
  tls:
    termination: edge
  port:
    targetPort: 8080-tcp
  to:
    kind: Service
    name: myapp
    weight: 100
  wildcardPolicy: None
status:
  ingress:
  - conditions:
    - lastTransitionTime: 2018-04-09T15:40:04Z
      status: "True"
      type: Admitted
    host: myapp-jimgarrett.apps.rhpds.openshift.opentlc.com
    routerName: router
    wildcardPolicy: None

Step 4: Verify

Verify by visiting your page by using the https:// URI

Congratulations!! In this exercise you have learned about service SSL from your application

Let’s clean up the project.

oc delete project binarydeploy-UserName
