How to scale ThreadFix services.

Prerequisites

Audience: IT Professional
Difficulty: Intermediate
Time needed: Approximately 10 minutes
Tools required: If any

There are two ways to scale services in ThreadFix, using Helm values or by directly modifying the Kubernetes deployment. Changes made using Helm values will persist until changed again. Changes made directly on the Kubernetes deployment will persist until the next upgrade.

Enter the following commands on a command line to perform the described action.

Using Kubernetes

1. Get a list of Kubernetes deployments associated with the ThreadFix application:

   Code Block
   kubectl get deploy -l kubernetes.io/part-of=threadfix

2. Scale the desired services (replace <numReplicas> with the number of pods to scale to and <deployment> with the name of the resource to scale):

   Code Block
   kubectl scale --replicas=<numReplicas> deployment/<deployment>

Using Helm

1. Get the Helm release name for the ThreadFix instance:

   Code Block
   TF_RELEASE=$(helm ls | grep threadfix | awk '{print $1}')

2. Get the current installed version of ThreadFix:

   Code Block
   TF_VERSION=$(helm ls --filter "$TF_RELEASE" | grep -o 'threadfix-[Az0-9\.\-]*' | sed 's|threadfix-||g')

3. Export the currently installed Helm values:

   Code Block
   helm get values $TF_RELEASE > myValues.yaml

4. Edit the resources 'replicaCount' field in myValues.yaml with the desired number or pods:

   • For example, to scale appsec-data to 2 pods, add the following to the myValues.yaml/code

     Code Block
     appsecdata: replicaCount: 2

   • Use the following to get a list of editable fields:

     Code Block
     helm inspect values denimgroup/threadfix

5. Run a helm upgrade with the modified values field:

   Code Block
   helm upgrade $TF_RELEASE denimgroup/threadfix --version $TF_VERSION -f myValues.yaml
