v1.2.0

What's Changed

Feature

• Introduced a Prometheus-compatible metrics endpoint #176
  • Enable with --metrics-server; serves /metrics with control plane health gauges on 127.0.0.1:9105 (configurable via --metrics-bind-address)
• Added support for attaching to a host-managed container runtime (containerd or CRI-O) #181
  • Set --container-runtime-endpoint (e.g. unix:///run/crio/crio.sock) to skip the embedded containerd; the host then supplies the runtime, OCI runtime, CNI plugin binaries and sandbox image
• Added CPU manager support for latency-sensitive workloads #183
  • New --cpu-manager-policy, --cpu-manager-policy-options, --system-reserved and --reserved-cpus flags
  • For more details, refer to this docs
• Auto-detect the network MTU, with an override via --mtu #179
  • Picks up reduced MTUs on VPN/tunnel/PPPoE links and applies them to the CNI bridge (cni0) and pod veth interfaces
  • For more details, refer to this docs
• Portainer Edge Agent now tracks the lts tag, and the image is configurable via --portainer-edge-image #177
  • Any image other than the default is pulled from the registry rather than loaded from the embedded image

Fixes

• Fixed an issue where the EXTERNAL-IP was not set when an existing service was changed to type LoadBalancer #178
  • Also added --load-balancer-ip to publish services on an address other than the node IP
• Fixed kubesoloctl writing the kubeconfig to the wrong user's home directory #185
  • Ownership is now resolved only from an explicit sudo/doas escalation; in a plain root shell (e.g. after sudo su -) the kubeconfig goes to root's home rather than being attributed to the original login user
• Fixed external-dependency builds embedding artifacts they do not use #184

Chore

• Updated KubeSolo to track Kubernetes v1.35.7 and Kine v0.16.3 #180
• Dropped the :latest container image tag and split CI publishing to be fork-safe #174
  • Images must now be pulled by an explicit version tag
• Bumped google.golang.org/grpc 1.80.0 -> 1.82.1 #175
• Bumped github.com/google/cel-go 0.26.0 -> 0.29.0 #182

New Contributors

• @c92s made their first contribution in #184
