Developers Guide💣

Big Bang is designed in such a way as to be as easily deployed locally as it is in production. In fact, most contributions begin locally.

Iron Bank Images💣

Per the charter, all Big Bang packages will leverage container images from IronBank. In order to pull these images, ImagePullSecrets must be provided to Big Bang. To obtain access to these images, follow the guides below. These steps should NOT be used for production since the API keys for a user are only valid when the user is logged into Registry1

  1. Register for a free Iron Bank account Here
  2. Log into the Iron Bank Registry, in the top right click your Username and then User Profile to get access to your CLI secret/API keys.
  3. When installing BigBang, set the Helm Values registryCredentials.username and registryCredentials.password to match your Registry1 username and API token

Local Kubernetes cluster💣

Follow the steps below to get a local Kubernetes cluster for Big Bang using k3d.

# Create a local k3d cluster with the appropriate port forwards (tested on version 5.4.1)
k3d cluster create --k3s-arg "--no-deploy=metrics-server,traefik@server:*" -p 80:80@loadbalancer -p 443:443@loadbalancer

Deploying Big Bang (Quick Start)💣

For development, it is quicker to test changes without having to push to Git. To do this, we can bypass Flux2 and deploy Big Bang directly with its Helm chart.

Start by creating myvalues.yaml to configure your local Big Bang. The Big Bang template repository contains a starter development values.yaml.

Configure myvalues.yaml to suit your needs.

# Deploy the latest fluxv2 with Iron Bank images
# For development, you can use flux from the internet using 'flux install`
# Be aware, the internet version is likely newer than the Iron Bank version
./scripts/install_flux.sh

# Apply a local version of the Big Bang chart
# NOTE: This is the alternative to deploying a HelmRelease and having flux manage it, we use a local copy to avoid having to commit every change
helm upgrade -i bigbang chart -n bigbang --create-namespace -f myvalues.yaml

# It may take Big Bang up to 10 minutes to recognize your changes and start to deploy them.  This is based on the flux `interval` value set for polling.  You can force Big Bang to immediately check for changes by running the ./scripts/sync.sh script.
./scripts/sync.sh

For more extensive development, use the Development Guide.

Testing Big Bang Development Changes💣

Development changes should be tested using a full GitOps environment. The Big Bang environment template should be replicated, either on a branch or new repository, to start your deployment. Follow the instructions in the template’s readme and in the Big Bang docs for configuration.

Follow the Big Bang documentation for testing a full deployment of Big Bang.

DNS💣

To ease with local development, the TLD bigbang.dev is maintained by the Big Bang team with the CNAME record:

CNAME: *.bigbang.dev -> 127.0.0.1

All routable endpoints BigBang deploys will use the TLD of bigbang.dev by default. It is expected that consumers modify this appropriately for their environment.

Secrets & Certificates💣

Follow instructions in the Big Bang encryption guide for how to encrypt and decrypt secrets.

Merge requests process💣

The merge request process is provided as an overview of the pipeline stages required to get a commit merged.

Follow instruction in CI-Workflow for specific details on the pipeline stages.
