Bety

Bety is a Web-interface to the Biofuel Ecophysiological Traits and Yields Database (used by PEcAn and TERRA REF)

Prerequisites

• Kubernetes
• Helm3

Installation

Before installing chart, make sure you enable NCSA repository.

helm repo add ncsa https://opensource.ncsa.illinois.edu/charts/

To install the chart with the release name my-release:

helm install my-release ncsa/betydb

Tip: List all releases using helm list

The command deploys Betydb on the Kubernetes cluster in the default namespace and configuration.

To install the chart in a specific namespace:

kubectl create namespace my-namepsace
helm install my-release ncsa/betydb -n my-namepsace

If the password is generated you will need to save this secret before you upgrade. You can do this using the following commands. If you do not do this, you will not be able to retrieve the previous secrets.

echo BETY_PASSWORD=$(kubectl get secrets betydb -o json | jq -r '.data.betyPassword' | base64 -d)
echo BETY_SECRETKEY=$(kubectl get secrets betydb -o json | jq -r '.data.secretKey' | base64 -d)
echo POSTGRESQL_PASSWORD=$(kubectl get secrets betydb-postgresql -o json | jq -r '.data."postgresql-password"' | base64 -d)

Tip: List all secrets in the default namespace

If you wanted to have it into the particular namespace, you can try below sample one

echo BETY_PASSWORD=$(kubectl get secrets betydb -n your_namespace -o json | jq -r '.data.betyPassword' | base64 -d)

Tip: Make sure you have created your own namespace before listing out the secrets kubectl create namespace your_namespace.

Upgrading BETY

You can also upgrade and use the secrets retrieved.

helm upgrade betydb ncsa/betydb \
    --set betyPassword="${BETY_PASSWORD}" \
    --set secretKey="${BETY_SECRETKEY}" \
    --set postgresql.postgresqlPassword="${POSTGRESQL_PASSWORD}"

The following table lists the configurable parameters of the Bety chart and their default values per section/component:

Common parameters

image.tag	Bety image tag	null
image.pullPolicy	Bety image pull policy	IfNotPresent
image.pullSecrets	Specify docker-registry secret names as an array	[] (does not add image pull secrets to deployed pods)
replicaCount	Number of Bety Pods to run	1
nodeSelector	Node labels for pod assignment	{} (evaluated as a template)
tolerations	Tolerations for pod assignment	[] (evaluated as a template)
affinity	Affinity for pod assignment	{} (evaluated as a template)
service.type	Kubernetes Service type	ClusterIP
service.port	Service HTTP port	8000
betyUser	User value for bety.user	bety
betyPassword	Password value for bety.password	bety
betyDatabase	Name of the database for bety.database	bety

Ingress parameters

Parameter	Description	Default
ingress.enabled	Enable ingress controller resource	false
ingress.host	Default host for the ingress resource	[] (evaluated as a template)

ingress.annotations	Ingress annotations	[] (evaluated as a template)

PostgreSQL parameters

Parameter	Description	Default
postgresq.auth.enablePostgresUser	Create the postgres user, this is the root account for postgresql.	true
postgresq.auth.postgresPassword	Password for postgres user	supersecret

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

helm install mt-release ncsa/betydb \
    --set betyPassword="xxxx" \
    --set secretKey="xxxx" \
    --set postgresql.auth.postgresqlPassword="xxxx"

The above command sets the bety password, secret, postgresql password to xxxx,xxxx, and xxxx respectively.

Alternatively, a YAML file that specifies the values for the necessary parameters can be provided while installing the chart. For example,

helm install --name my-release -f values.yaml .

Tip: You can use the default values.yaml

Uninstalling the Chart

To uninstall/delete the my-release deployment:

helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.
