Upgrade ISD-Argo Platform from v4.1.2 to v4.1.3

This document describes how to upgrade the ISD-Argo Platform from v4.1.2 to v4.1.3 on a Kubernetes cluster.

Before starting the upgrade, take a backup of all the databases, particularly the Postgres DB. The backup procedures may vary depending on your usage of external DBs for Autopilot Services.

Please note that v4.1.2 to v4.1.3 upgrade does not depend on or use an external script for db upgrade or data migration. So upgrading the helm chart would be enough.

Following are the sequence of activities to perform the upgrade.

  1. Pre-requisites

  2. Cloning the Repo and update values file

  3. Helm upgrade

  4. Post Installation Steps

  5. If an upgrade fails

Pre-requisites:

  • Users need to have access to the Kubernetes Cluster and namespace where “ISD-Argo with Argo CD and Argo Rollouts” is running i.e v4.1.2 is running.

  • Users need to have access to GitHub and be able to clone enterprise-argo repo.

Cloning the Repo and update values file:

  1. Clone the enterprise-argo repo by using the below command 

    git clone https://github.com/OpsMx/enterprise-argo.git
cd enterprise-argo/charts/isdargo/

  2. You need to use isd-argo-minimal-values.yaml file for upgrading to v4.1.3.

  3. Configure URLs for ISD-Argo Platform, Keycloak and Vela as per your DNS record.

  4. Update the URLs of ISD-Argo Platform, Keycloak and Vela as per your DNS records in all occurrences of the isd-minimal-values.yaml

  5. Update forwarder.externalName URL in isd-minimal-values.yaml. The actual DNS needs to be created/updated after installation.

The isd-minimal-values.yaml provided in the repo is adequate and recommended for ISD-Argo Platform standard Installation. If you would like to have some advanced-level configurations for secret management, cluster configuration, etc, you can use values.yaml. If you need any additional clarifications with respect to values.yaml for installation, please contact OpsMx support. Click here for the complete values.yaml

Helm upgrade

  1. Add OpsMx helm repo to your local machine.

helm repo add isdargo https://opsmx.github.io/enterprise-argo/

If OpsMx helm repo is already added, do a repo update before installing the chart by executing the below command.

helm repo update

  1. Execute the below command to upgrade.

helm upgrade isd isdargo/isdargo -f isd-minimal-values.yaml -n opsmx-argo
--timeout=15m --debug

Wait for 15 minutes till the helm upgrade completes.

helm upgrade isd isdargo/isdargo -f isd-minimal-values.yaml -n opsmx-argo 
--timeout=15m --debug

Release "isd" has been upgraded. Happy Helming!
NAME: isd
LAST DEPLOYED: Mon Feb  6 19:40:34 2023
NAMESPACE: opsmx-argo
STATUS: deployed
REVISION: 2
TEST SUITE: None

  1. Please use the below command to check the pods in your namespace.

kubectl -n opsmx-argo get pods

  1. Once installation is completed, please create/update the DNS, based on the loadbalancer created using instructions here.

Post Installation Steps

  1. Vela Service requires the “Wild-card ingress” and “Wild-card TLS certificates to be provided to the ingress”. If you are using the cert-manager, please use this blog to create a Wild-card TLS certificate. Else please contact your certificate provider for the certificates for your URL equivalent for "*.VELA.REPLACE.THIS.WITH.YOURCOMPANY.COM".

    Create vela-ingress tls secret using the wild-card certificate and key. Replace cert1.pem and privkey1.pem file in the below command with the certificates you have created from cert manager or your certificate provider. For example, kubectl create secret tls vela-ingress -n opsmx-argo --cert cert1.pem --key privkey1.pem

  2. Login to ISD UI and check whether the ISD version is updated right after the help button in the top right corner.

  3. Go to the Agent Screen in ISD UI and click on the three dots at the end of the row of the Agent entry and then click the Edit button as shown in the image below.

  4. Click the Download Agent Manifest button to download the Agent Manifest file as shown in the image below.

  5. Apply the Agent Manifest file where ISD-Argo Platform is running by using the below command.

    kubectl apply -f isd-argo-agent.yml -n opsmx-argo

  6. Delete the Agent pod by using the below command. kubectl delete po -l agent.opsmx.com/role=agent -n opsmx-argo

  7. Go to the “CD Integration” page and check whether the agent status is healthy(green) as shown in the image below.

  8. Please verify all the screens in ISD UI.

If an upgrade fails

If anything goes wrong during upgrade, please use the below command to get the helm history.

helm history isd -n opsmx-argo
