Quipucords Helm Chart

Helm Chart for the Discovery product.

Install and Uninstall the Discovery product to OpenShift and Kubernetes via the helm command-line tool which must be installed as a prerequisite.

This Helm Chart has been deployed to the following environments:

• OpenShift 4.15.0
• OpenShift 4.13.12
• CRC Local 2.27 / OpenShift 4.13.12 / Podman 4.4.4

The Helm chart lives in the discovery subdirectory and can be installed as follows to use the default discovery name:

First, download this repo:

$ git clone https://github.com/quipucords/quipucords-helm-chart.git
$ cd quipucords-helm-chart

Next, login to OpenShift and set your working Namespace/Project for discovery:

$ oc login https://api.<your_cluster>:6443 -u kubeadmin -p <kubeadmin_password>
$ oc project discovery-helm

Then, install discovery:

$ helm install discovery ./discovery --set server.password="EXAMPLE-superadmin1"
NAME: discovery
LAST DEPLOYED: Sun Dec  3 16:09:56 2023
NAMESPACE: discovery-helm
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES: ...

To uninstall the above release of discovery:

$ helm uninstall discovery
release "discovery" uninstalled

If there is a need to install multiple discovery instances to the same namespace, install discovery with a unique instance name as follows:

$ helm install --generate-name ./discovery --set server.password="EXAMPLE-superadmin2"
NAME: discovery-1612624192
LAST DEPLOYED: Sun Dec  3 16:09:56 2023
NAMESPACE: discovery-helm
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES: ...

To uninstall the above release of discovery, specify the instance name:

$ helm uninstall discovery-1612624192
release "discovery-1612624192" uninstalled

Note that helm list will show the installed Charts in the namespace:

$ helm list
NAME                	NAMESPACE     	REVISION	UPDATED                             	STATUS  	CHART          	APP VERSION
discovery-1702314666	discovery-helm	1       	2023-12-11 12:11:07.898808 -0500 EST	deployed	discovery-0.9.1	1.4.5
discovery-1702314671	discovery-helm	1       	2023-12-11 12:11:11.442539 -0500 EST	deployed	discovery-0.9.1	1.4.5

Note, by default the Discovery Django secret key used is development, for production, an alternate secret key should be used. The Django secret key gets stored with the discovery-secrets and should be specified at initial deployment as follows:

$ helm install --generate-name ./discovery \
  --set server.password="EXAMPLE-superadmin1" \
  --set server.djangoSecretKey="production1"

By default, the Discovery product uses the discovery-pull-secret if defined. If a different pull secret is needed specify the alternate name as follows:

$ helm install discovery ./discovery \
    --set server.password="EXAMPLE-superadmin1" \
    --set global.imagePullSecrets[0].name=alternate-discovery-pull-secret

Other than the generated names by Helm, custom Discovery release names can be used as follows:

$ helm install discovery-dev ./discovery \
    --set server.password="EXAMPLE-superadmin1"
...
$ helm install discovery-qe ./discovery \
    --set server.password="EXAMPLE-testadmin1"
...

And can be uninstalled by their given names:

$ helm uninstall discovery-dev discovery-qe

For development use cases a simple Makefile is provided as a wrapper to helm.
