brew upgrade git but macOS Still Shows Old Version? Fixing Apple Git vs Homebrew Git Conflict

Due to security issues, we need to upgrade the current git version to the latest. actively exploited by attackers. If Git is not updated in time, simply cloning a malicious repository could allow hackers to run harmful code on your computers. All users with self-managed Git are asked to update their installations to the following secure versions immediately (v2.43.7, v2.44.4, v2.45.4, v2.46.4, v2.47.3, v2.48.2, v2.49.1, and v2.50.1 or later). % git --version git version 2.39.3 (Apple Git-145) % brew upgrade git Error: git not installed % brew update ==> Updating Homebrew...

The reason is : On macOS, you currently have two Git versions installed: Apple’s system Git (comes preinstalled with macOS/Xcode Command Line Tools) Version: 2.39.3 (Apple Git-145) Location: usually in /usr/bin/git Homebrew Git Version: 2.51.0 Location: usually in /usr/local/bin/git (Intel Mac) or /opt/homebrew/bin/git (Apple Silicon) When you type git --version, your shell is picking Apple’s Git first, not the Homebrew one. ✅ How to check both Git locations: which -a git ✅ To see what version is actually being used by your shell: type -a git 🔧 Fix: Use Homebrew’s Git by adjusting your PATH Add Homebrew’s bin directory before system paths. For Apple Silicon (M1/M2/M3): echo 'export PATH="/opt/homebrew/bin:$PATH"' >> ~/.zshrc source ~/.zshrc For Intel Macs: echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.zshrc source ~/.zshrc Then verify: git --version It should now show: git version 2.51.0

Kubernetes Node Registration Error

0715 16:24:50.191095 109018 kubelet_node_status.go:72] "Attempting to register node" node="nodesadhu1" I0715 16:24:50.198556 109018 kubelet_node_status.go:75] "Successfully registered node" node="nodesadhu1" E0715 16:24:50.198604 109018 kubelet_node_status.go:535] "Error updating node status, will retry" err="error getting node \"nodesadhu1\": node \"nodesadhu1\" not found" E0715 16:24:50.215963 109018 kubelet_node_status.go:453] "Error getting the current node from lister" err="node \"nodesadhu1\" not found" E0715 16:24:50.316519 109018 kubelet_node_status.go:453] "Error getting the current node from lister" err="node \"nodesadhu1\" not found"

This appears to be Kubernetes kubelet logs showing a node registration issue. Here's what's happening:

The Issue: The kubelet is experiencing a race condition during node registration. While it successfully registers the node "nodesadhu1" with the API server, it immediately encounters errors when trying to update the node status because the node can't be found in the local cache/lister. To understand, please read this: https://sadhusuresh.blogspot.com/2025/08/kubelet-informerlister-synchronization.html

What's happening step by step:

Kubelet attempts to register node "nodesadhu1"
Registration succeeds with the API server
Kubelet tries to update node status but fails because the node isn't found in the local node lister
This creates a timing issue where the API server knows about the node but the local kubelet cache doesn't

Common causes:

Network latency between kubelet and API server
API server being under heavy load
Issues with the kubelet's informer/lister synchronization
Temporary connectivity issues

Typical resolution: This is usually a transient issue that resolves itself as the kubelet retries. The kubelet will continue attempting to update the node status until the local cache synchronizes with the API server state.

If the issue persists:

Check API server connectivity and response times
Verify cluster network health
Review API server logs for any errors
Consider restarting the kubelet if the issue doesn't self-resolve

The "will retry" message indicates the kubelet has built-in retry logic, so this often resolves automatically within a few minutes.

Kubelet Informer/Lister Synchronization Guide

Understanding the Concept

What is an Informer/Lister?

Informer: A client-side component that watches Kubernetes API resources and maintains a local cache Lister: An interface that reads from the local cache (not directly from API server)

Think of it like this:

API Server = Central database
Informer = Local sync agent that keeps a copy
Lister = Local query interface that reads the copy

The Synchronization Process

API Server                    Kubelet
┌─────────────┐              ┌──────────────────┐
│   Nodes     │              │    Informer      │

                             │     Lister       │
                             │ (Read from cache)│
                             └──────────────────┘

Example Scenario: Node Registration Race Condition

Step-by-Step Breakdown

Kubelet starts up

Kubelet: "I need to register myself as node 'worker-01'"

Node registration succeeds

API Server: "OK, node 'worker-01' created"
Kubelet Log: "Successfully registered node worker-01"

Kubelet tries to update node status

Kubelet: "Let me get node 'worker-01' from my local cache"
Lister: "Sorry, I don't see 'worker-01' in my cache yet"

The problem
- API Server has the node
- Local cache doesn't have it yet (sync delay)
- Kubelet gets "node not found" error

Why This Happens

Timing Issue Example:

Time 0ms:  Kubelet sends CREATE node request
Time 50ms: API Server creates node
Time 60ms: API Server responds "SUCCESS" to kubelet
Time 65ms: Kubelet tries to read node from local cache
Time 65ms: ERROR - node not in cache yet!
Time 100ms: Informer receives WATCH event about new node
Time 110ms: Local cache updated with new node

How to Trace in Logs

1. Increase Kubelet Logging Verbosity

# Add these flags to kubelet
--v=4  # For informer sync logs
--v=6  # For detailed API calls

2. Key Log Patterns to Look For

A. Informer Startup and Sync

# Informer starting
I0715 kubelet.go:xxx] "Starting informer" controller="node"

# Waiting for cache sync
I0715 shared_informer.go:xxx] "Waiting for caches to sync" controller="node"

# Cache sync completed
I0715 shared_informer.go:xxx] "Caches are synced" controller="node"

B. Node Registration Sequence

# 1. Registration attempt
I0715 kubelet_node_status.go:72] "Attempting to register node" node="worker-01"

# 2. Registration success
I0715 kubelet_node_status.go:75] "Successfully registered node" node="worker-01"

# 3. Immediate status update attempt (PROBLEM HERE)
E0715 kubelet_node_status.go:535] "Error updating node status, will retry" 
     err="error getting node \"worker-01\": node \"worker-01\" not found"

C. Lister Access Patterns

# Lister trying to find node
E0715 kubelet_node_status.go:453] "Error getting the current node from lister" 
     err="node \"worker-01\" not found"

# Eventually, cache catches up
I0715 kubelet_node_status.go:xxx] "Successfully updated node status" node="worker-01"

3. Diagnostic Commands

Check Current Node Cache State

# Get kubelet metrics
curl -s http://localhost:10255/metrics | grep informer

# Check if node exists in API server
kubectl get nodes worker-01

# Check kubelet's view
crictl info | grep -A 5 node

Monitor Real-time Logs

# Follow kubelet logs with filtering
journalctl -u kubelet -f | grep -E "(informer|lister|register|sync)"

# Or for containerized kubelet
kubectl logs -n kube-system kubelet-xxx -f | grep -E "(informer|lister)"

Complete Log Analysis Example

Healthy Sequence

I0715 16:20:10.100 kubelet.go:xxx] "Starting node informer"
I0715 16:20:10.150 shared_informer.go:xxx] "Waiting for caches to sync"
I0715 16:20:10.200 shared_informer.go:xxx] "Caches are synced"
I0715 16:20:15.100 kubelet_node_status.go:72] "Attempting to register node" node="worker-01"
I0715 16:20:15.200 kubelet_node_status.go:75] "Successfully registered node" node="worker-01"
I0715 16:20:15.250 kubelet_node_status.go:xxx] "Successfully updated node status" node="worker-01"

Problematic Sequence (Your Case)

I0715 16:24:50.100 shared_informer.go:xxx] "Caches are synced"  # Cache thinks it's ready
I0715 16:24:50.191 kubelet_node_status.go:72] "Attempting to register node" node="nuvlrknpcimn01"
I0715 16:24:50.198 kubelet_node_status.go:75] "Successfully registered node" node="nuvlrknpcimn01"
                                                                # ↑ API call succeeds
I0715 16:24:50.198 kubelet_node_status.go:535] "Error updating node status, will retry" 
     err="error getting node \"nuvlrknpcimn01\": node \"nuvlrknpcimn01\" not found"
                                                                # ↑ Lister call fails (7ms later!)

Troubleshooting Steps

1. Check Informer Health

# Look for informer sync issues
kubectl logs -n kube-system kubelet-xxx | grep -A 5 -B 5 "sync"

2. Verify Network Connectivity

# Test API server connectivity
curl -k https://$KUBERNETES_API_SERVER/api/v1/nodes

# Check kubelet to API server latency
time kubectl get nodes --server=$KUBERNETES_API_SERVER

3. Monitor Cache Refresh

# Watch for informer resync events
kubectl logs -n kube-system kubelet-xxx | grep -E "(resync|refresh|list.*nodes)"

4. Resource Constraints

# Check if kubelet is under resource pressure
top -p $(pgrep kubelet)
kubectl top nodes

Prevention and Solutions

1. Increase Kubelet Timeouts

# kubelet config
apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
nodeStatusUpdateFrequency: 10s
nodeStatusReportFrequency: 1m

2. Add Retry Logic Monitoring

# Monitor retry attempts
journalctl -u kubelet | grep "will retry" | wc -l

3. API Server Optimization

# API server flags for better performance
--max-requests-inflight=400
--max-mutating-requests-inflight=200

This synchronization issue typically resolves itself, but understanding the logs helps you distinguish between transient startup issues and persistent problems.
