Briefly, this error occurs when Elasticsearch is bound to an external IP address or a non-loopback address, which triggers the enforcement of bootstrap checks. These checks are safety measures to prevent potential issues in a production environment. To resolve this, you can either bind Elasticsearch to a loopback address (like 127.0.0.1) for development purposes, or ensure that your system meets all the production environment requirements (like having at least half of the available physical RAM allocated to Elasticsearch, correct file descriptor count, etc.) to pass the bootstrap checks.
