with a Helm Chart

Parasoft has published an official Helm chart to Docker Hub for your convenience. Full installation instructions are included in the README there. See https://hub.docker.com/r/parasoft/lss-helm.

Deploying License Server in Kubernetes Manually

Prerequisites

First, create

...

To deploy License Server in Kubernetes, follow the directions described below.

Prerequisites

First, create a namespace for License Server to run in. For example:

kubectl create namespace parasoft-lss-namespace

Note: The namespace name "parasoft-lss-namespace" is used throughout this documentation in command and resource examples. If you use a different name for your namespace, be sure to change any instances of "parasoft-lss-namespace" in those examples to your namespace name.

Next, you will Next, you will need a Kubernetes cluster. After starting the cluster, create the service account and permissions required by the License Server pod and related resources.

# Stable access for clients to license server
apiVersion: v1
kind: ServiceAccount
metadata:
  name: parasoft-account
  namespace: parasoft-lss-namespace
automountServiceAccountToken: true
---
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  name: parasoft-read
  namespace: parasoft-lss-namespace
rules:
- apiGroups:
  - "*"
  resources:
  - "*"
  verbs:
  - get
  - read
  - list
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: parasoft-read-bind
  namespace: parasoft-lss-namespace
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: Role
  name: parasoft-read
subjects:
- kind: ServiceAccount
  name: parasoft-account
  namespace: parasoft-lss-namespace

...

If you want to set up a custom keystore, you will need to create a configuration map for the " .keystore " and " server.xml " files. The command below creates a configuration map called "keystore-cfgmap" with file mappings for the custom " .keystore " and " server.xml" filesxml files. In this example, each file mapping is given a key: "keystore" for the .keystore file and "server-config" for the server.xml file. While giving each file mapping a key is not necessary, it is useful when you don't want the key to be the file name. 

...

Create the License Server Environment

To create the License Server environment, you will first need a yaml file that defines a secret Secret (optional), a volume, a podPod or StatefulSet, and a service Service (optional). The secret Secret is used to pull the License Server image from the repository. The Pod or StatefulSet creates a pod is set up to run a License Server container configured with a volume to persist data and a liveness probe for the container health. The service Service makes License Server accessible via external clients by allocating ports in the node and mapping them to ports in the pod. An example yaml file called Example yaml files for a Pod or StatefulSet (both called "parasoft-lss.yaml" is ) are shown below. This example uses These examples use an NFS volume, but that is not required; use the volume type that fits your needs best.

Note: kind: Deployment is not supported. Use either kind: Pod or kind: StatefulSet, which are supported.

kubectl create -f parasoft-lss.yaml

To access the UI on a web browser, use the node ports allocated in the service definition as the address (for example, NODE_HOST:NODE_PORT).

If you injected JVM arguments into the container and want to verify their status, run the following command:

kubectl exec <POD_NAME> -c <CONTAINER_NAME> -- printenv

Required Settings for a Stable Machine ID

As you modify either of the parasoft-lss.yaml samples shown above or craft your own yaml, be aware that the following fields need to be consistent across upgrades and redeployments in order to assure a stable machine ID:

• metadata: name
• metadata: namespace
• containers: name

In addition, the following environment variables are required:

• env: name: PARASOFT_POD_NAME
• env: name: PARASOFT_POD_NAMESPACE

Custom Truststore

Using a custom truststore in Kubernetes environments is similar to using a custom keystore as described above. Adjust the Using a custom truststore in Kubernetes environments is similar to using a custom keystore as described above. Adjust the directions for using a custom keystore as appropriate. Note that the truststore location is /usr/local/parasoft/license-server/app/jre/lib/security/cacerts.

...

1. Copy log4j.xml from the <INSTALL_DIR>/app/ directory to <INSTALL_DIR>/data/.

2. Open the log4j.xml file in <INSTALL_DIR>/data/ and add the following logger in Loggers element:

   Code Block
   language text
   <Logger name="com.parasoft.xtest" level="ALL"> <AppenderRef ref="CONSOLE" /> </Logger>

3. Find commented-out section for LSS_JAVA_OPTS in the yaml file, uncomment it, then add the following as the value for LSS_JAVA_OPTS:

   Code Block
   language yml
   -Dparasoft.cloudvm.verbose=true -Dparasoft.logging.config.file=/usr/local/parasoft/license-server/data/log4j.xml

4. Restart the application.

5. Additional logging will go to catalina log file (stdout).  You can run this command to get the log file to local file system (replace "lss-pod1-nfs" with your pod name and "parasoft-lss-namespace" parasoft-lss-namespace" with the namespace you used):

   Code Block
   language text
   kubectl logs lss-pod1-nfs -n parasoft-lss-namespace > lss-debug.log

Deploying License Server in Kubernetes with a Helm Chart

1. with the namespace you used):

   Code Block
   language text
   kubectl logs lss-pod1-nfs -n parasoft-lss-namespace > lss-debug.log

Troubleshooting

machineId is LINUX2-0

This issue can occur when there is an underlying permission issue. To resolve it, try the following options:

1. Verify that you have created permissions required by License Server using parasoft-permissions.yaml.
   • Note: if you are upgrading, make sure to use the parasoft-permissions.yaml for the version to which you are upgrading.
2. Confirm that all Parasoft-required resources are using the same namespace.

machineId changes when pod restarts

This issue can occur if you are using an unsupported Kubernetes object. Make sure you are not using kind: Deployment. Only kind: Pod and kind: StatefulSet are supported. Parasoft has published an official Helm chart to Docker Hub for your convenience. Full installation instructions are included in the readme.
