Setup Instructions

Prerequisites

• Kubernetes cluster 1.20 or later with at least 4 cores and 16 GB memory

• Helm 3 is setup on the client system with 3.10.3 or later

• Ensure that this URLs(ISD,KeyCloak,Vela) is reachable from your browser. Either DNS name server record must exist or "hosts" file must be updated.The following 3 URLs need to be exist in DNS and point to Loadbalancer IP of the nginx ingress controller.

   Ip-address ISD.REPLACE.THIS.WITH.YOURCOMPANY.COM
  
   Ip-address KEYCLOAK.REPLACE.THIS.WITH.YOURCOMPANY.COM
   
   Ip-address *.VELA.REPLACE.THIS.WITH.YOURCOMPANY.COM

  E.g.: isd.isd-argo.opsmx.com

• Vela Service requires the “Wild-card ingress” and “Wild-card TLS certificates to be provided to the ingress”

  Please use below blog to create a Wild-card TLS certificates to provide for the Ingress, if you are using the cert-manager.

  https://www.linkedin.com/pulse/wildcard-certificates-using-lets-encrypt-certbot-pallavi-udhane/

  Else please contact your certificate provider for the certificates for your URL equivalent for "*.VELA.REPLACE.THIS.WITH.YOURCOMPANY.COM"

• An additional host URL may be required depending on your requirements. See below for instructions

  • controller host url and/or
  • ArgoCD host url

• Use below command to check if helm is installed or not

  helm version

  If helm is not setup, follow https://helm.sh/docs/intro/install/ to install helm.

Installation Instructions

• Add opsmx helm repo to your local machine

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

  Note: If opsmx helm repo is already added, do a repo update before installing the chart

  helm repo update

• Your Kubernetes cluster should support persistent volumes

• It is assumed that an nginx ingress controller is installed on the cluster, by default ingress resources are created for oes-ui, keycloak, vela and argocd services. Customize the hosts for various installations using the options in the values.yaml under oesUI, keycloak, vela, argo-cd. If any other ingress controller is installed, set createIngress flag to false and configure your ingress.

  Instructions to install cert-manager https://cert-manager.io/docs/installation/kubernetes/

• Helm v3 expects the namespace to be present before helm install command is run. If it does not exists,

  kubectl create namespace opsmx-argo

• There are different flavours of Installations

  Values yamls	Description
  isd-minimal-values.yaml	This file is used for Installing only ISD without Argo CD and Argo Rollouts
  isd-argo-minimal-values.yaml	This file is used for Installing ISD,Argo CD and Argo Rollouts
  isd-rollouts-values.yaml	This file is used for Installing ISD and Argo Rollouts without Argo CD
  onlyargorollouts-values.yaml	This file is used for Installing only Argo Rollouts without Argo CD and ISD
  argocd-rollouts-values.yaml	This file is used for Installing Argo CD and Argo Rollouts without ISD

NOTE: In all the values.yaml please read inline comments and update it accordingly.

Install ISD

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

• Use below command to install ISD using the helm chart:

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

• Please create/update the DNS based on the loadbalancer created using instructions here: https://docs.google.com/document/d/1cahEx4NihwRyqZtFijTJ79Zxe8_PixuKrosAocxSIrk/edit#

• Create vela-ingress tls secret using the wild-card certificate and key e.g. kubectl create secret tls vela-ingress -n opsmx-argo --cert cert1.pem --key privkey1.pem

Install ISD-ARGO

• OPTIONAL: Update forwarder.externalName URL in isd-argo-minimal-values.yaml. The actual DNS needs to be created after installation

• Apart of above 3 urls update the Argo CD Url in the DNS name server record must exist or "hosts" file must be updated.

   Ip-address ARGO.REPLACE.THIS.WITH.YOURCOMPANY.COM

• Use below command to install ISD-ARGO using the helm chart:

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

• OPTIONAL: Please create/update the DNS based on the loadbalancer created using instructions here: https://docs.google.com/document/d/1cahEx4NihwRyqZtFijTJ79Zxe8_PixuKrosAocxSIrk/edit#

• Create vela-ingress tls secret using the wild-card certificate and key e.g. kubectl create secret tls vela-ingress -n opsmx-argo --cert cert1.pem --key privkey1.pem

NOTE: The OPTIONAL steps above can be done after the installation at a later point, if required by following all the steps in the document.

Tip: List all releases using helm list

Troubleshooting

1. Everything installed but I don't see any applications.

• If "full" installed is used (i.e. isd-argo-minimal-values.yaml), it automatically installs sample applications, including a working rollouts sample.
• If connecting to an existing argo or adding a new argo, please ensure that the user-token generated has admin RBAC permissions.

2. Clicking on an application in Home-screen takes me to a blank page or a page with an error

• Vela service needs wild-card DNS and wild-card TLS certificates for this work due to restrictions in ArgoCD.
• We can test it by opening another tab in the browser and putting going to "isd.VELA.REPLACE.THIS.WITH.YOURCOMPANY.COM", it should load and say "Failed to load".

Uninstall

To uninstall/delete the deployment

Uninstalling the ISD

helm uninstall isd -n opsmx-argo

Uninstalling the ISD-ARGO
