I’ve set up the FluentBit → OpenSearch log pipeline a few times across different environments. Each time I hit the same set of underdocumented rough edges. This is the post I wish I’d found the first time.

What It Was # Migration Manager was an in-house client/server platform built at Hawaiian Airlines to migrate FluentBit log exporter configurations from a legacy log repository (ElasticSearch on AWS) to its replacement (AWS OpenSearch) — across a fleet of 100+ systems, without downtime.

What It Was # RPM Back-Port Publisher was an in-house pipeline built at Hawaiian Airlines to solve a specific, urgent problem: getting a patched version of Squid onto production RHEL 8 and 9 systems after Red Hat’s standard package update cycle couldn’t deliver one in a reasonable timeframe.
