Let’s Encrypt is a free Certificate Authority (CA) that issues SSL certificates. You can use these SSL certificates to secure traffic to and from your Bitnami application host.
This guide walks you through the process of generating a Let’s Encrypt SSL certificate for your domain and installing and configuring it to work with your Google Cloud Platform Bitnami application stack.
The Bitnami HTTPS Configuration Tool is a command line tool for configuring mainly HTTPS certificates on Bitnami stacks, but also common features such as automatic renewals, redirections (e.g. HTTP to HTTPS), etc. This tool is located in the installation directory of the stack at /opt/bitnami.
To launch the Bitnami HTTPS Configuration Tool, execute the following command and follow the prompts: sudo /opt/bitnami/bncert-tool
