How do I set up SSL certificates for Elasticsearch?
To set up SSL certificates for Elasticsearch, you need to generate a certificate, configure Elasticsearch to use it, and then restart the service.
What type of certificate should I use?
You can use self-signed certificates for testing, but for production, it's recommended to use certificates from a trusted Certificate Authority (CA).
Can you guide me through generating a self-signed certificate?
Sure! You can use OpenSSL to generate a self-signed certificate. The command is: openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
.
How do I configure Elasticsearch to use the generated certificates?
You need to edit the elasticsearch.yml
file to include the paths to your certificate and key files under the xpack.security.transport.ssl
settings.
