Steps for migrating to IBM Kubernetes Service¶
Perform a transformation on your IBM Cloud Foundry application via move2kube transform
In the transform phase, we detect our plan and will perform a transformation using the plan. You'll be asked a series of questions related to the application itself, your image registry, and your cluster. During this phase, we will build images for each of the services in our application and push those images into the image registry. Later, we will use the image registry to pull the images and deploy them into the cluster.
Invoke the Move2Kube's transform on the plan
move2kube transform
Keep the default transformer type (press Enter).
Output:
INFO[0000] Detected a plan file at path /Users/elvinjohngalarza@ibm.com/move2kube-iks-demo/move2kube-demos-clean1/m2k.plan. Will transform using this plan.

After the images are built locally, we can push them into our registry.

Now that the images are pushed, we can pull them into our cluster. Let's log into our cluster.
Perform the following command and log into the account that has access to your IBM Kubernetes cluster.
ibmcloud login
Validate that your cluster is shown when listing all clusters:
ibmcloud ks clusters
Initialize kubectl
command environment by replacing the placeholder <your-cluster-id>
with the appropriate cluster ID that was displayed earlier:
ibmcloud ks cluster config -c <your-cluster-id> --admin
You should now be able to perform kubectl
commands on that IBM Kubernetes cluster.
You can now create a new namespace to deploy your application to.
kubectl create namespace move2kube-demo
With the namespace created, you must move the IBM Cloud Container Registry secret called all-icr-io
into the newly created namespace. The secret is deployed to the default
namespace automatically upon creation of the cluster, so that secret can be copied into the new namespace.
kubectl get secret all-icr-io -n default -o yaml | sed "s/default/move2kube-demo/" | kubectl apply -n move2kube-demo -f -
Now that the all-icr-io
secret is copied over to the move2kube-demo
namespace, the application is ready to be deployed.
cd ..
cd deploy
ls
Output:
cicd knative
yamls compose

Apply the YAML files located in myproject/deploy/yamls
.
kubectl apply -f yamls --namespace=move2kube-demo
Output:

Let's take a look at the deployments.
kubectl get deployments --namespace=move2kube-demo
Output:

frontend 2/2 2 2 55s
gateway 2/2 2 2 55s
inventory 2/2 2 2 55s
orders 2/2 2 2 55s
Let's take a look at the pods.
kubectl get pods --namespace=move2kube-demo
Output:

Let's take a look at the services.
kubectl get svc --namespace=move2kube-demo
Output:
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
customers ClusterIP 172.21.118.116 <none> 8080/TCP 5m22s

orders ClusterIP 172.21.2.136 <none> 8080/TCP 5m22s
Finally, let's take a look at the ingress. We can perform a kubectl
command like the above, but let's take a look at the web console instead.
In the web console, select the move2kube-demo
Namespace.
Under Service, navigate to Ingresses.
You should see a Topology view of all the enterprise-app
components in the form of pods.
Click the "Open url" icon on the frontend pod.
You should be taken to the frontend of the enterprise-app
.
Congrats! You've successfully migrated the enterprise-app
application from IBM Cloud Foundry application to an IBM Kubernetes cluster.
