Update go.mod and all golang build images from 1.26.1 to 1.26.2 to pick up the upstream 2026-04-07 security release.
This includes fixes for CVE-2026-32280 / CVE-2026-32281 in crypto/x509, CVE-2026-32283 in crypto/tls, and the related toolchain and standard library security fixes shipped in go1.26.2, without changing any unrelated dependencies.
This commit changes the container base image
from ubi-minimal to ubi-micro.
The docker build process happens now in two stages.
The build stage:
- downloads the latest CA certificate bundle
- downloads MinIO binary (for requested version/os/arch)
- downloads MinIO binary signature and verifies it
using minisign
Then it creates an image based on ubi-micro with just
the minio binary was downloaded and verified during the
build stage.
The build stage is simplified to just verifying the
minisign signature.
