CURL Elasticsearch CAcert | Setup Guide

by | Jan 31, 2024

When using Elasticsearch, CURL defines CAcert. Let’s look into the details. At Bobcares, with our Server Management Service, we can handle your issues.

CAcert using CURL in Elasticsearch

We must verify that a communication with an Elasticsearch cluster over HTTPS is secure by verifying the SSL certificate of the server. A CAcert can be specified for SSL certificate validation using the curl CLI tool, which is often used to make HTTP requests. With Elasticsearch, the following way it works:

curl elasticsearch cacert

1. We can give the path to a CA certificate file using the CACert Option (–cacert) in curl. During the SSL/TLS handshake, the CA certificate is used in order to confirm that the server’s SSL is genuine.

2. Elasticsearch displays its SSL certificate during the SSL handshake when it is set up to support HTTPS connections. Here, the client must confirm that the certificate the server has sent is genuine and has been signed by a reliable CA.

3. Usually, we have to provide the path to a CA certificate file together with the –cacert option if we want to use curl with Elasticsearch securely. The SSL certificate that the Elasticsearch server presented was signed by this CA certificate.

Using a trusted CA certificate is vital. It can be issued by a reliable CA or one that we have self-signed. The Elasticsearch server’s SSL certificate is confirmed to be authentic and unintercepted by malicious entities when it is used with a trusted CA certificate. We may also need to give curl extra options, like username or password. This depends on how Elasticsearch is setup and how security is setup.

Conclusion

To conclude, curl’s cacert option allows us to safely interact via HTTPS with the Elasticsearch cluster.
