How to change Grafana port to 443?

Grafana operates on port 3000 by default, but we may change this to any other accessible port. HTTPS transmission, which is encrypted and hence more secure than plain HTTP traffic, uses port 443.

By changing the default port to 443, we will be able to access your Grafana instance through HTTPS, which will provide extra protection for the data.

Configuration

Here’s how to set the Grafana port to 443:

1. Stop the currently operating Grafana container using the following command:

   docker stop container-name
2. In a directory of our choosing, create a new file called grafana.ini. This file will contain the Grafana instance’s configuration parameters.
3. To set Grafana to utilize port 443, add the following lines to the grafana.ini file:

   [server] http_port = 443 protocol = https
4. Create a new Docker container using the grafana/grafana image and use the -v option to mount the grafana.ini file as a volume in the container. As an example, consider the following command:

   docker run -d -p 443:443 \ -v /path/to/grafana.ini:/etc/grafana/grafana.ini \ --name grafana \ grafana/grafana

   This program launches a new Grafana container and redirects port 443 from the host system to port 443 in the container.

   The -v option mounts the grafana.ini file as a volume in the container, allowing Grafana to access the file’s configuration parameters.
5. In a web browser, navigate to https://your-server-ip>:443 to access the Grafana instance via HTTPS.

   The Grafana login screen should now appear, and all future traffic between the browser and the Grafana instance should be secured.

It’s worth mentioning that using HTTPS necessitates the installation of a valid SSL/TLS certificate on the server.

Using Certbot or another similar tool, we can obtain a free SSL/TLS certificate from Let’s Encrypt. In addition, the firewall may need to be setup to accept inbound traffic on port 443.
