* [client,proxy,management,signal,relay] Distrust compromised eMudhra CA keys
Eight eMudhra intermediate CA private keys were compromised and browsers
blocked them on 2026-10-17. Our binaries were built with go1.26.7, which
accepts chains through those intermediates whenever the trust store still
holds emSign ECC Root CA - G3. go1.26.10 rejects them in crypto/x509 on
every platform, regardless of the trust store.
The UBI base still ships the root and Red Hat has no fixed package yet, so
the UBI images blocklist it with p11-kit. The ingest image, the UI server
image and the pinned Chainguard digests also carried the root and move to
bases that no longer do.
* [client,proxy,management,signal,relay] Use the fixed UBI base instead of a blocklist
Red Hat shipped ca-certificates 2026.2.92_v9.0.319-90.3 on 2026-10-22,
which drops emSign ECC Root CA - G3 and AAA Certificate Services. The
current ubi9-minimal image carries it, so pin that digest and remove the
p11-kit blocklist step.
* [misc] Pin upload-server images by digest only and restore go.mod comment
upload-server/Dockerfile only packaged the goreleaser-built binary, so
the image could not be built from a checkout. It is now a multi-stage
build on Chainguard static, running as the nonroot user (uid 65532),
with a VARIANT=debug build arg that swaps in busybox for a shell.
The goreleaser packaging file moves unchanged to Dockerfile.release and
.goreleaser.yaml points at it, so the published netbirdio/upload image
stays as it was: distroless and root.
The bases are pinned by digest, since Chainguard publishes only :latest
for free. A Dependabot docker entry for /upload-server moves them
weekly, leaving the release base alone and holding golang to patch
updates.
- introduce variables to avoid publishing latest docker tags and installers
- Refactor .goreleaser.yaml to simplify docker configurations and add environment-driven flags
- removed management debug containers (it was doing only log var)
- Stopped building arm v6 32bits in favor of v7 32 bits for services (not client)
- Add target argument to docker files
Add an upload bundle option with the flag --upload-bundle; by default, the upload will use a NetBird address, which can be replaced using the flag --upload-bundle-url.
The upload server is available under the /upload-server path. The release change will push a docker image to netbirdio/upload image repository.
The server supports using s3 with pre-signed URL for direct upload and local file for storing bundles.
