Upgrade Kubernetes 2.0 Agent

This guide provides instructions for updating the Kubernetes 2.0 OpsRamp Agent using Helm. It includes step-by-step instructions for both Helm version 3.10.0 or later and earlier versions. It also cover guidance on modifying configuration keys, updating to the specific versions, and handling custom settings for proxy servers and ports.

For Helm Version 3.10.0 or Above

1. To upgrade the Kubernetes 2.0 Agent to the latest helm version, use the following command:

   helm upgrade <release-name> <helm-repo-url> --reset-then-reuse-values

   For example, if the release name is opsramp, the command will be:

   helm upgrade opsramp oci://us-docker.pkg.dev/opsramp-registry/agent-helm-charts/agent --reset-then-reuse-values

The above command will upgrade the Agent to the latest helm version available in the OpsRamp Agent Helm Repository.

2. To upgrade the Kubernetes 2.0 Agent to a specific helm version, use the --version flag in the command.
   For example, to upgrade to helm version 0.1.0, use:

   helm upgrade opsramp oci://us-docker.pkg.dev/opsramp-registry/agent-helm-charts/agent --version 0.1.0 --reset-then-reuse-values

3. If the opsramp-master agent pod does not restart automatically after the upgrade, run:

   kubectl rollout restart deployment opsramp-master

Change Agent Configuration Keys

To modify any keys in the opsramp-agent-config configMap, use the Helm upgrade command with the current agent version.
For example, if you want to change the proxy server and port, run:

helm upgrade opsramp-agent oci://us-docker.pkg.dev/opsramp-registry/agent-helm-charts/agent --version 0.1.0 --reset-then-reuse-values  --set agent.config.proxy.server="172.24.5.7",agent.config.proxy.port="3128" 

For Helm Versions Below 3.10.0

1. To upgrade the Kubernetes 2.0 Agent to the latest helm version, use the following command:

   helm get values my-release -o yaml > /tmp/opsramp-current-values.yaml
   
   helm upgrade <release-name> <helm-repo-url> --reset-values -f /tmp/opsramp-current-values.yaml
   
   rm /tmp/opsramp-current-values.yaml

   For example, if the release name is opsramp, the command will be:

   helm get values my-release -o yaml > /tmp/opsramp-current-values.yaml
   
   helm upgrade opsramp oci://us-docker.pkg.dev/opsramp-registry/agent-helm-charts/agent --reset-values -f /tmp/opsramp-current-values.yaml
   
   rm /tmp/opsramp-current-values.yaml

The above command will upgrade the Agent to the latest helm version available in the OpsRamp Agent Helm Repository.

2. To upgrade the Kubernetes 2.0 Agent to a specific helm version, use the --version flag in the command.
   For example, to upgrade to helm version 0.1.0, use:

   helm get values my-release -o yaml > /tmp/opsramp-current-values.yaml
   
   helm upgrade opsramp oci://us-docker.pkg.dev/opsramp-registry/agent-helm-charts/agent --version 0.1.0 --reset-values -f /tmp/opsramp-current-values.yaml
   
   rm /tmp/opsramp-current-values.yaml

3. If the opsramp-master agent pod does not restart automatically after the upgrade, run:

   kubectl rollout restart deployment opsramp-master

Change Agent Configuration Keys

To modify any keys in the opsramp-agent-config configMap, use the Helm upgrade command with the current agent version.
For example, if you want to change the proxy server and port, run:

helm get values my-release -o yaml > /tmp/opsramp-current-values.yaml


helm upgrade opsramp-agent oci://us-docker.pkg.dev/opsramp-registry/agent-helm-charts/agent --version 0.1.0 --reset-values  -f /tmp/opsramp-current-values.yaml --set agent.config.proxy.server="172.24.5.7",agent.config.proxy.port="3128"  


rm /tmp/opsramp-current-values.yaml
