Upgrade PSA in Minikube

Upgrade the Private Synthetic Agent

To upgrade the PSA, perform the following steps:

1. Pull the Docker Image
2. (Optional) Add Custom Python Libraries
3. Tag and Push Images to the Registry
4. Update the Helm Chart
5. Upgrade the PSA

Pull the Docker Image

Pull the pre-built docker images for sum-chrome-agent, sum-api-monitoring-agent, and sum-heimdall from DockerHub. The pre-built images include the dependent libraries, so you can use these images even when you do not have access to the Internet.

Run the following commands to pull the agent images:

docker pull appdynamics/heimdall-psa

docker pull appdynamics/chrome-agent-psa

docker pull appdynamics/api-monitoring-agent-psa

Add Custom Python Libraries

This is an optional step. In addition to the available standard set of libraries, you can add custom Python libraries to the agent to use in scripted measurements. You build a new image based on the image you loaded as the base image.

1. Create a Dockerfile and then create RUN directives to run python pip. For example, to install the library algorithms you can create a Dockerfile: 
   

   # Use the sum-chrome-agent image you just loaded as the base image
   FROM appdynamics/chrome-agent-psa:<agent-tag>
   
   USER root
   RUN apk add py3-pip
   USER appdynamics
     
   # Install algorithm for python3 on top of that
   RUN python3 -m pip install algorithms==0.1.4 --break-system-packages

   CODE
   

   You can create any number of RUN directives to install the required libraries.

2. To build the new image, enter: 
   Web Monitoring PSA:

   docker build -t sum-chrome-agent:<agent-tag> - < Dockerfile

   CODE

   The newly built agent image contains the required libraries.
   API Monitoring PSA:

   docker build -f Dockerfile-PSA -t sum-api-monitoring-agent:<monitoring-tag> .

   CODE

   The newly built agent image contains the required libraries.

Tag and Push Images to the Registry

Managed Kubernetes services, such as EKS or AKS, provide container registries where you can push your image. No other configuration is needed. Kubernetes cluster within EKS or AKS will have the access to these images.

To tag the images, enter:

docker save sum-heimdall:<heimdall-tag> | (eval $(minikube docker-env) && docker load)
docker save sum-chrome-agent:<agent-tag> | (eval $(minikube docker-env) && docker load)
docker save sum-api-monitoring-agent:<agent-tag> | (eval $(minikube docker-env) && docker load)

Update the Helm Chart

Follow these steps and update the configuration key value pairs in the values.yaml file:

Upgrade the PSA

From PSA 23.12 onwards, you must deploy Ignite and Heimdall in a single namespace named measurement.

1. Navigate to the new Linux distribution folder and run the following command:

   helm install synth ignite-psa.tgz --values values-ignite.yaml --namespace measurement

   CODE

2. Wait until the status of Ignite pods changes to running. Then, run the following command:
   

   helm upgrade heimdall-onprem sum-psa-heimdall.tgz --values values.yaml --namespace measurement

   CODE

    

3. After the status of the new Heimdall and Ignite pods changes to running, uninstall the old Ignite namespace:

   helm uninstall synth -n ignite

   CODE
