Use when Fluent Bit on Kubernetes does not deliver logs: the DaemonSet crashes on a config error ("tried to instance a plugin name that doesn't exist", "unknown configuration property", "configuration file contains errors"), an output fails ("failed to flush chunk", "cannot be retried", "no upstream connections available", "getaddrinfo", "Connection refused"), records arrive without Kubernetes metadata ("could not get meta for POD"), lines arrive unparsed or not at all…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fluent Bit troubleshooting Find out why Fluent Bit does not ship logs, and propose a fix. **Read first, ask before changing.** Run the investigation commands freely. Run a command under an "Ask first" line only after the user approves that exact command; if your credentials do not allow it, give it to the user to run. Never run a "Proposed fix"; hand it to the user. Fluent Bit runs as a DaemonSet: on every node a **tail** input reads the container log files under `/var/log/containers/`, the **kubernetes** filter adds pod metadata from the API server, and **outputs** send the records to a backend (Elasticsearch, Loki, an HTTP endpoint, a forwarder). Its own log names each part as `[input:tail:tail.0]`, `[filter:kubernetes:kubernetes.0]`, `[output:http:http.0]`, so the log usually names the cause. The Helm chart keeps the config in a ConfigMap (`fluent-bit.conf`); the **Fluent Operator** builds it from custom resources into a Secret. The commands use placeholders: `my-namespace`, `my-fluent-bit` (the DaemonSet, its ConfigMap and its ServiceAccount), `my-fluent-bit-pod` (one of its pods) and `my-backend` (the Service an output sends to). Replace them with the real names. Never …

How to install
mdr add k8s-servant/k8s-skills/k8s-fluent-bit-troubleshooting@sha256:e5eac515b40f9b3aThe line at the top of this page pins the label git:20261025.ccfa9e2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
