Nected OnPremise

Installation using Helm charts

Pre-Requisite

1. An external Application Load Balancer with Ingress.

2. Map 4 domains to loadbalaner
   • <<frontend-konark-domain>>
   • <<frontend-editor-domain>>
   • <<backend-nalanda-domain>>
   • <<backend-vidhaan-router-domain>>
   • Configure external access only if rule/workflow API or webhook needs to be reachable from outside.
3. need to enable storage drivers, e.g: for AKS:

   az aks update -n <Cluster Name> -g <Resource Group> --enable-disk-driver --enable-file-driver --enable-blob-driver --enable-snapshot-controller
   

Deployment steps

1. Add Nected Repo:

    helm repo add nected https://nected.github.io/helm-charts
   

2. Download sample files into values folder:
   • Datastore values
   • Admintools values
   • Temporal values
   • Nected Services values
3. Update following values in “values/*.yaml” files, adjust Ingress annotations based on ingressClass, and consider switching domains to https in case going to use SSL certificates.
   • <<LicenseKey>>
   • <<frontend-konark-domain>>
   • <<frontend-editor-domain>>
   • <<backend-nalanda-domain>>
   • <<backend-vidhaan-router-domain>>
   • <<MongoPassword>>
   • <<PostgresUserName>>
   • <<PostgresPassword>>
   • <<ElasticUserPass>>
   • <<ingressClassName>>
   • <<pathType>>
   • <<DefaultUser>>
   • <<DefaultPassword>>
   • <<senderEmail>>
   • <<SendeName>>
   • <<emailHostName>>
   • <<senderUsername>>
   • <<senderPassword>>
   • <<ingressClassName>>
4. When installing databases with nected’s chart, include datastore in the installation.

   helm install datastore nected/datastore -f values/datastore-values.yaml
   

5. After deploying datastore, install Temporal’s admin tools and initialize its schema.

    helm install admintools nected/temporal -f values/admintools-values.yaml
   
    kubctl get pods
    kubectl exec -it admintools-temporal-admintools-xxxxxxx-xxxx -- /bin/bash
   
    export SQL_PLUGIN=postgres
    export SQL_HOST=datastore-postgresql
    export SQL_PORT=5432
    export SQL_USER=<<PostgresUserName>>
    export SQL_PASSWORD=<<PostgresUserName>>
   
    temporal-sql-tool --db temporal create-database
    SQL_DATABASE=temporal temporal-sql-tool setup-schema -v 0.0
    SQL_DATABASE=temporal temporal-sql-tool update -schema-dir schema/postgresql/v96/temporal/versioned
   
    temporal-sql-tool --db temporal_visibility create-database
    SQL_DATABASE=temporal_visibility temporal-sql-tool setup-schema -v 0.0
    SQL_DATABASE=temporal_visibility temporal-sql-tool update -schema-dir schema/postgresql/v96/visibility/versioned
   

6. Now install temporal:

    helm install temporal nected/temporal -f values/temporal-values.yaml
   

7. Install Nected services:

    helm install nected nected/nected -f values/nected-services-values.yaml
   

With all services running, access the application through the fronend-konark domain using the default username and password.
