Install Deepfactor portal using Helm

Download the required helper scripts from Deepfactor.

# create a directory for the files
mkdir deepfactor-certs

# change directory
cd deepfactor-certs/

wget https://static.deepfactor.io/scripts/public/df-portal/cert-gen/generate-cert.sh
wget https://static.deepfactor.io/scripts/public/df-portal/cert-gen/openssl-portal.cnf
wget https://static.deepfactor.io/scripts/public/df-portal/cert-gen/openssl-portalca.cnf

Generate certificate

Navigate to the download directory and run the script generate-cert.sh with your preferred domain name as the argument to the script.

chmod +x generate-cert.sh
sudo ./generate-cert.sh <DNS-of-your-portal>

Create Kubernetes secret from the certificates generated by the previous step.

# create new certificates secret
