Briefly, this error occurs when Elasticsearch is moved from development mode to production mode. In production mode, Elasticsearch enforces a set of mandatory bootstrap checks to ensure its proper and secure operation. If any of these checks fail, Elasticsearch will not start. To resolve this issue, you need to address the failed checks. This could involve adjusting your system settings, such as increasing the file descriptor count, disabling memory swapping, or configuring the network settings correctly. Always ensure your system meets the requirements specified in the Elasticsearch documentation.
We recommend you run Elasticsearch Error Check-Up which can resolve issues that cause many errors.
Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).
Quick Overview
Elasticsearch kicks several bootstrap checks to make sure basic cluster configurations are according to recommendations. And if you see this log, that means it is explicitly doing all checks. For further reading please see – bootstrap checks It can be turned on/off using the below steps: Users can enable/disable all these checks explicitly by setting to true/false in JVM options.
"es.enforce.bootstrap.checks" : true/false (set either true or false)
Log Context
Log “explicitly enforcing bootstrap checks” classname is BootstrapChecks.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :
}
if (enforceLimits) {
logger.info("bound or publishing to a non-loopback address; enforcing bootstrap checks");
} else if (enforceBootstrapChecks) {
logger.info("explicitly enforcing bootstrap checks");
}
for (final BootstrapCheck check : checks) {
final BootstrapCheck.BootstrapCheckResult result = check.check(context);
if (result.isFailure()) {
