This guide walks you through the steps required to set up DIGIT using helmfile.
git
Kubernetes Cluster
Helmfile is a declarative spec for deploying helm charts. It lets you…
Keep a directory of chart value files and maintain changes in version control.
Apply CI/CD to configuration changes.
Periodically sync to avoid skew in environments.
To avoid upgrades for each iteration of helm, the helmfile executable delegates to helm - as a result, must be installed.
Standardisation of Helm templates (Override specific parameters such as namespace)
To improve the Utilisation of Helm capabilities (Rollback)
Easy to add any open-source helm chart to your DIGIT stack
run as a container
Archlinux: install via pacman -S helmfile
You can also use a shim to make calling the binary easier:
The helmfile init sub-command checks the dependencies required for helmfile operation, such as helm, helm diff plugin, helm secrets plugin, helm helm-git plugin, helm s3 plugin. When it does not exist or the version is too low, it can be installed automatically.
The helmfile sync sub-command syncs your cluster state as described in your helmfile. The default helmfile is helmfile.yaml, but any YAML file can be passed by specifying a --file path/to/your/yaml/file flag.
The helmfile apply sub-command begins by executing diff. If diff finds that there are any changes, sync is executed. Adding --interactive instructs Helm File to request your confirmation before sync.
The helmfile destroys sub-commands uninstalls and purges all the releases defined in the manifests. helmfile --interactive destroy instructs Helm File to request your confirmation before actually deleting releases.\
Update domain name in env.yaml
Update db password , flywaypassword, loginusername, loginpassword and git-sync private key in env-secrets.yaml
Note: Make sure the db_password and flywaypassword are same
Run the below command to install DIGIT successfully.
This guide outlines a deployment strategy for running containerized applications on Kubernetes, focusing on seamless database integration. It's suitable for teams looking to simplify their database setup using in-cluster PostgreSQL or externally managed database services.
By updating the Kubernetes deployment configuration, teams can easily switch from an in-cluster PostgreSQL database to a managed service. This move enhances scalability and reliability while reducing the operational overhead of database management.
Scalability and Reliability: Managed services offer superior scalability and reliability compared to in-cluster databases.
Reduced Operational Overhead: Outsourcing database management allows teams to concentrate on application development.
To integrate a managed PostgreSQL service, modify the following parameters in the
deploy-as-code/charts/environments/env.yaml configuration file:
db-host: Update with the database service host address.
db-name: Update with the specific database name.
db-url: Update with the complete database connection URL.
domain: Update domain name with your domain name
Update db password, db username, flyway username, flyway password, login username, login password and git-sync private key in env-secrets.yaml
Run the below command to install DIGIT successfully.

Tested Environment
This deployment approach has been thoroughly tested on an Amazon Web Services Elastic Kubernetes Service (AWS EKS) Cluster with Kubernetes version 1.28.\

open SUSE: install via zypper in helmfile assuming you are on Tumbleweed; if you are on Leap you must add the repo for your distribution version once before that command, e.g. zypper ar https://download.opensuse.org/repositories/devel:/kubic/openSUSE_Leap_\$releasever kubic
