chart, salt: Bump Fluent Bit chart to 0.58.3 and Fluent Bit image to … by riadelhajjaji-scality · Pull Request #5164 · scality/metalk8s

riadelhajjaji-scality · 2026-10-13T13:53:17Z

Summary:

Bump the Fluent Bit chart from 0.57.7 to 0.58.3, and Fluent Bit from 5.0.7 to 5.1.3.
The chart releases in between only update the Fluent Bit image

Upstream changes reviewed against our configuration:

Adaptive flushing (flush.adaptive, 5.1.0): disabled by default, we
keep Flush 1
The metrics used by our alerts (fluentbit_input_ingestion_paused,
fluentbit_input_storage_overlimit,
fluentbit_output_retries_failed_total) are still exposed
out_loki fixes (Remove_Keys with several Loki outputs,
tenant_id_key): we use 3 Loki outputs, but neither option
in_systemd journal namespace support: opt-in, our input does not
set it
Security hardening of input handling and the HTTP server: we only
use the HTTP server for metrics and health checks
filter_kubernetes metadata for internal logs: only applies to the
fluentbit_logs input, which we do not use
The image keeps the same base (Debian 13, libsystemd 257)

Acceptance criteria:

The CI passes: installation, expansion, upgrade and downgrade t
Fluent Bit pods run 5.1.3 and are Ready on every node

Closes: #MK8S-346

Branches have diverged

This pull request's source branch feature/MK8S-346-bump-fluent-bit has diverged from
development/136.0 by more than 50 commits.

To avoid any integration risks, please re-synchronize them using one of the
following solutions:

Merge origin/development/136.0 into feature/MK8S-346-bump-fluent-bit
Rebase feature/MK8S-346-bump-fluent-bit onto origin/development/136.0

Note: If you choose to rebase, you may have to ask me to rebuild
integration branches using the reset command.

No changelog entry: there is no file under .changes/unreleased/ and no /changie comment, even though earlier bumps have one and the /etc/machine-id mount fixes a user-visible bug (host logs not reaching Loki)
- Post a /changie comment with an Enhanced entry for the chart 0.58.3 / Fluent Bit 5.1.3 bump
- Add a separate Fix entry saying host (systemd journal) logs reach Loki again

/changie Enhanced Bump fluent-bit chart to 0.58.3 and Fluent Bit image to v5.1.3

Bump the Fluent Bit chart from 0.57.7 to 0.58.3, and Fluent Bit itself from v5.0.7 to v5.1.3. The chart releases between 0.57.7 and 0.58.3 only update the Fluent Bit image, the rendered Salt state only changes the image tag and the version labels. Fluent Bit v5.0.7 -> v5.1.3 is a minor release with bug and security fixes, the main changes are: - 5.0.8/5.0.9: in_tail crash and out-of-bounds read fixes, out_loki tenant_id_key handling fix - 5.1.0: adaptive flushing (`flush.adaptive`), FIPS mode, new metrics and node exporter collectors - 5.1.2: in_systemd journal namespace support, filter_kubernetes namespace exclude, out_loki Remove_Keys fix with several Loki outputs - 5.1.3: security hardening of input handling and the HTTP server, fix of chunk placement under storage backpressure No breaking change upstream. Changes that could impact MetalK8s: - adaptive flushing is disabled by default, we keep `Flush 1` - the metrics used by our alerts (`fluentbit_input_ingestion_paused`, `fluentbit_input_storage_overlimit`, `fluentbit_output_retries_failed_total`) are still exposed - out_loki fixes: we use 3 Loki outputs, but neither Remove_Keys nor Tenant_ID_Key - in_systemd namespace support: opt-in, our input does not set it - HTTP server hardening: we only use it for metrics and health checks - filter_kubernetes metadata for internal logs: only applies to the fluentbit_logs input, which we do not use The digest has been updated by pulling the image from the registry using: gcrane digest cr.fluentbit.io/fluent/fluent-bit:5.1.3 Ref: MK8S-346

✅ Changelog check passed.

claude · 2026-10-20T09:35:46Z

PR description is out of date: it still lists mounting /etc/machine-id and expects host logs ({job="fluent-bit", unit!=""}) in Loki as an acceptance criterion, but that change is no longer in this diff
- Remove the /etc/machine-id bullet and the host-logs criterion, or link the separate PR that now carries the fix
