Kubernetes
The IBM Security Verify Access OIDC Provider (ISVAOP) image is available on IBM Cloud Container Registry.
See Software Downloads > Containers for more information.
Pre-requisites
Configuration
The configuration for the container is supplied as YAML files, template files, JavaScript files along with other potential supporting files (e.g. PEM certificate files).
Note
Boilerplate YAML configuration is available for download from the Resources Github Repository.
When the container starts, it processes configuration found at '/var/isvaop/config' directory. As such, the configuration for the container will need to be present in this directory before the container is started or mounted as part of startup.
There are different ways by which the ISVAOP container can be packaged to start with the configuration information. Here are some non-exhaustive options:
- Pre-baking the configuration into a new image which is based on the ISVAOP image. A Dockerfile which can be used to create a pre-baked image is shown below:
##
## You can build this image by issuing the following command:
## docker build -t acme-isvaop:1.0 $PWD
##
## The container is based on the ISVAOP container.
FROM icr.io/isva/verify-access-oidc-provider:24.08
## Copy the configuration files from the data directory
## to the docker image.
COPY data/. /var/isvaop/config/
## Some labels which will be associated with the image.
LABEL maintainer="[email protected]" \
vendor="ACME"
- Using Kubernetes ConfigMaps and Secrets to hold configuration information.
Approach: Using Kubernetes resources
Pre-deployment steps
-
Create a Kubernetes Secret for Keystores, Certificates and Keys.
Put the following files in the same folder and use the command line to create the Secret.
- P12 keystore and the obf file contains the P12's obfuscated password.
- Individual keystore .zip file. Make sure the keystore zip file has the
personal
andsigner
folders at its root. - PEM format certificate and key files.
Use the following command to create the Secret:
kubectl create secret generic isvaop-keystores --from-file=./keystores
-
Create a Kubernetes Secret for Server Credentials.
Create a Kubernetes Secret yaml file with the server credentials as shown in the following example.
kind: Secret apiVersion: v1 metadata: name: isvaop-server stringData: db_hostname: ... db_hostport: ... db_username: ... db_password: ... db_db_name: ... ... type: Opaque
Use the following command to create the Secret:
kuberctl apply -f server_secret.yml
-
Create a Kubernetes Secret for obfuscation and encryption keys.
Create a Kubernetes Secret yaml file with the server credentials as shown in the following example.kind: Secret apiVersion: v1 metadata: name: isvaop-obf stringData: obf_key: "ENC:<encrypted_obf_key>" enc_key: | -----BEGIN RSA PRIVATE KEY----- ... -----END RSA PRIVATE KEY----- type: Opaque
Use the following command to create the Secret:
oc apply -f obf_secret.yml
-
If necessary, create more Kubernetes Secrets.
-
Create a Kubernetes ConfigMap for static clients.
Put the client yaml files in the same folder, and use the following command to create the ConfigMap:
kubectl create configmap isvaop-clients --from-file=./clients
-
Create a Kubernetes ConfigMap for access policies.
Put the access policy files in the same folder, and use the following command to create the ConfigMap:
kubectl create configmap isvaop-access-policies --from-file=./accesspolicy
-
Create a Kubernetes ConfigMap for mapping rules.
Put the mapping rule files in the same folder, and use the following command to create the ConfigMap:
kubectl create configmap isvaop-mapping-rules --from-file=./mappingrule
-
Create a Kubernetes ConfigMap for customized template pages.
Compress the customized template pages. Make sure the .zip file has the language folders like
C
,fr
, andit
at its root.
Use the following command to create the ConfigMap:kubectl create configmap isvaop-templates --from-file=./templates.zip
-
If necessary, create more Kubernetes ConfigMaps.
-
Create the main Kubernetes ConfigMap with top-level configuration keys.
- For more information about top-level keys and an example, see Configuration.
- For more information about YAML configuration details, see YAML Config Guide.
Create yaml configuration files with top-level keys, and use
configmap:
orsecret:
annotation refer to configurations in Kubernetes ConfigMaps or Secrets.- For more information about
configmap:
andsecret:
annotations, see Special Types Available in Kubernetes.
The configuration can in the same file or spread across multiple files.
Note
The configuration file extensions must be
.yml
or.yaml
.
Set top-level keyversion
to24.08
to enable full yaml configuration.The following code is a configuration file example with all top-level keys.

Put the configuration files with top-level keys in the same folder, and use the following command to create the ConfigMap:
kubectl create configmap isvaop-config --from-file=./config
-
Create a service account.
## Create a serviceaccount called isvaop.
kubectl create serviceaccount isvaop
- Assign ConfigMap and Secret read permission to the service account.
Create a role with ConfigMap and Secret read permission using the following command:
kubectl create role view-configmap-secret --verb=get,list,watch --resource=secrets,configmaps
Create a Rolebinding to assign the role to the service account by using the following command.
Note
The RoleBinding applies to the specific kubernetes namespace.
Replace
<namespace>
with the actual namespace.The default kubernetes namespace is
default
.
kubectl create rolebinding --role=view-configmap-secret <namespace>-isvaop-view-configmap-secret --serviceaccount=<namespace>:isvaop
Deployment
In order to deploy a running IBM Security Verify Access OIDC Provider container in a Kubernetes environment a deployment descriptor must first be created. The following deployment YAML file (isvaop-deployment.yaml) is a sample, which references the configmaps and secret created in the previous section.
Use the following isvaop-deployment.yml
to deploy the service.
##

## descriptor has dependencies on the file-based configuration.

# The liveness and readiness probes are used by Kubernetes
# to obtain the health of the container.
readinessProbe:
httpGet:
path: /healthcheck/ready
port: 8436
scheme: HTTPS
initialDelaySeconds: 30
timeoutSeconds: 30
periodSeconds: 30

path: /healthcheck/alive
port: 8436
scheme: HTTPS
initialDelaySeconds: 30

periodSeconds: 30
successThreshold: 1
failureThreshold: 10
The Kubernetes pod can then be created using the following command:
[demouser@demovm ~]$ kubectl apply -f isvaop-deployment.yml
You can monitor the bootstrapping of the pod as below:
[demouser@demovm ~]$ kubectl logs -f `kubectl get -o json pods -l app=isvaop | jq -r .items[0].metadata.name`
Service
The isvaop container will expose a single port for each protocol which is enabled for the server. For the HTTPS protocol the 8436 port is exposed. To make this port available from outside of the Kubernetes cluster a new service must be created. The following YAML file (isvaop-service.yaml) contains an example service definition:
##
## The service description of the isvaop service.
##
apiVersion: v1
kind: Service
metadata:
name: isvaop
spec:
ports:
- port: 8436
name: isvaop
protocol: TCP
nodePort: 30443
selector:
app: isvaop
type: NodePort
The service definition can then be created using the following command:
[demouser@demovm ~]$ kubectl apply -f isvaop-service.yaml
Updating the Configmap
-
To update the isvaop-config configmap, modify the configuration directory, then execute the following command:
[demouser@demovm ~]$ kubectl create configmap isvaop-config --from-file=./config -o yaml --dry-run | kubectl apply -f -
-
Delete the existing pod.
[demouser@demovm ~]$ kubectl delete pod <pod_name>
IBM Cloud
The IBM cloud container service provides advanced capabilities for building cloud-native apps, adding DevOps to existing apps, and relieving the pain around security, scale, and infrastructure management. Further information can be obtained from the IBM Cloud Web site: https://www.ibm.com/cloud/container-service
To set the context for the kubectl utility use the IBM Cloud CLI to obtain the kubectl configuration file:
## Log into IBM Cloud.
ibmcloud login -sso
## Obtain the list of available cluster.
ibmcloud ks clusters
## Show the details of the cluster.
ibmcloud ks workers <cluster-name>
## Create the kubectl configuration file.
ibmcloud ks cluster config <cluster-name>
## Set the kubectl configuration file.
export KUBECONFIG=<deployment-yaml>
