Deploying License Server in Kubernetes with a Helm Chart
...
Deploying License Server in Kubernetes Manually
Prerequisites
Namespace for LSS
First, create a namespace for License Server to run in. For example:
...
Warning |
---|
Once License Server has been licensed, deleting the namespace will invalidate machine-locked licenses, even if you recreate the same namespace. |
Service Account for LSS
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.

serviceaccount/parasoft-account created role.rbac.authorization.k8s.io/parasoft-read created rolebinding.rbac.authorization.k8s.io/parasoft-read-bind created |
Custom Keystore
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 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.
Code Block | ||
---|---|---|
| ||
~$ kubectl create configmap keystore-cfgmap --from-file=keystore=/path/to/.keystore --from-file=server-config=/path/to/server.xml
configmap/keystore-cfgmap created |
Create the License Server Environment
To create the License Server environment, you will first need a yaml file that defines a Secret (optional), a volume, a Pod or StatefulSet, and a Service (optional). The Secret is used to pull the License Server image from the repository. The Pod or StatefulSet creates a pod 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 makes License Server accessible via external clients by allocating ports in the node and mapping them to ports in the pod. Example yaml files for a Pod or StatefulSet (both called "parasoft-lss.yaml") are shown below. 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.

To set up License Server, create a yaml file that defines the following:
- Secret (optional)
- To pull the License Server image from the repository.
- Volume
- To persist data.
- Pod or StatefulSet
- Creates a pod set up to run a License Server container configured with a volume to persist data and a liveness probe for the container health.
- Service (optional).
- Makes License Server accessible via external clients by allocating ports in the node and mapping them to ports in the pod.
Example yaml files for a Pod or StatefulSet (both called "parasoft-lss.yaml") are shown below. These examples use an NFS volume, but that is not required; use the volume type that fits your needs best.
Required Settings for a Stable Machine ID
Anchor | ||||
---|---|---|---|---|
|
As you modify either of the parasoft-lss.yaml samples shown below 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

Create the License Server Environment
Use the yaml file to create the LSS environment:
Code Block | ||
---|---|---|

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 commandUse the yaml file to create the LSS environment:

kubectl createexec <POD_NAME> -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:

Custom Keystore
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 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.

Custom Truststore
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
.
Troubleshooting
Enabling Additional Logging
- Copy log4j.xml from the
<INSTALL_DIR>/app/
directory to<INSTALL_DIR>/data/
. 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>
Find commented-out section for
LSS_JAVA_OPTS
in the yaml file, uncomment it, then add the following as the value forLSS_JAVA_OPTS
:Code Block language yml -Dparasoft.cloudvm.verbose=true -Dparasoft.logging.config.file=/usr/local/parasoft/license-server/data/log4j.xml
- Restart the application.
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" 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:is an underlying permission issue. To resolve it, try the following options:
- Search the ls.log file found in the
<LS_DATA_DIR>/logs/
directory for a "fails to get UUID" message. - Verify that you have created permissions required by License Server using 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.
- Confirm that all Parasoft-required resources are using the same namespace.
