Day-33 - Kubernetes Ingress & Ingress Controllers

Day-33
Today’s focus was on Kubernetes Ingress & Ingress Controllers — the real gateway that connects the outside world to your in-cluster applications

In Kubernetes, Services like NodePort and LoadBalancer can expose applications externally — but they have their own challenges: higher cost, cloud dependency, and limited flexibility.
That’s where Ingress becomes a game changer

That’s where Ingress shines :
1) Learned how Ingress acts as a smart traffic router using host-based and path-based rules
2) Understood the difference between Ingress Resource, Ingress Controller, and LoadBalancer
3) Explored NGINX Ingress Controller setup (deployment via YAML and Helm)
4) Implemented routing for a “Hello World” app with custom domain mapping
5) Discovered how ingressClassName prevents conflicts in multi-controller clusters

Step-by-Step Explanation of Ballooning, Compression & Swapping in VMware

🔹 Step-by-Step Explanation of Ballooning, Compression & Swapping in VMware ⸻ 1️⃣ Memory Ballooning (vmmemctl) Ballooning is the first memory reclamation technique used when ESXi detects memory pressure. ➤ Step-by-Step: How Ballooning Works 1. VMware Tools installs the balloon driver (vmmemctl) inside the guest OS. 2. ESXi detects low free memory on the host. 3. ESXi inflates the balloon in selected VMs. 4. Balloon driver occupies guest memory, making the OS think RAM is full. 5. Guest OS frees idle / unused pages (because it believes memory is needed). 6. ESXi reclaims those freed pages and makes them available to other VMs. Why Ballooning Happens? • Host free memory is very low. • ESXi wants the VM to release unused pages before resorting to swapping. Example • Host memory: 64 GB • VMs used: 62 GB • Free: 2 GB → ESXi triggers ballooning • VM1 (8 GB RAM): Balloon inflates to 2 GB → OS frees 2 GB → ESXi re...

ESXi Host Troubleshooting Checklist

🛠️ ESXi Host Troubleshooting Checklist (With Complete Log Locations) ✅ 1. Host Status & Connectivity Check host state in vCenter (Connected / Not Responding / Disconnected) Review CPU, RAM, and datastore usage Validate HA/DRS recommendations ✅ 2. Hardware Health Monitor hardware sensors (CPU, DIMMs, fans, PSU, RAID) Check RAID controller logs via vendor tools View hardware status in: vCenter → Monitor → Hardware Health DCUI → Hardware Status ✅ 3. Network Validation Verify vSwitches, Port Groups, NIC teaming, VLAN tagging Check vmkernel ports (mgmt, vMotion, iSCSI, vSAN) Test reachability using: Shell vmkping < IP > Show more lines Validate physical NIC status and link speed ✅ 4. Storage & Datastore Checks Confirm datastore accessibility Rescan storage adapters (iSCSI/FC/NFS) Validate multipathing (Round Robin / Fixed / MRU) Check datastore latency with esxtop ✅ **5. Critical Logs & Their Locations (Full List) Here are key ESXi log files that every VMware adm...

vCenter Troubleshooting Tips, Common Issues & Log Locations 🚀 1. General Troubleshooting Approach A. Check service health first For vCenter Server Appliance (VCSA): Shell https : / / < vcenter - FQDN > : 5480 Show more lines Go to Services → Health to verify: vCenter Server ESXi hosts vSphere Client DNS, NTP, DB connections vpxd, vpxd-svcs, vsphere-ui B. DNS & NTP checks vCenter is highly dependent on correct DNS & time sync. Check: Shell nslookup < vcenter - fqdn > nslookup < esxi - host - fqdn > Show more lines Time drift > 5 minutes causes: Login failures vpxd crashes PSC authentication issues C. Check storage/database health Slow DB/storage = UI slow, tasks hung. For VCSA: Shell df - h du - sh / storage / log / * / var / log Show more lines Free up space if partitions hit >80%. D. Restart critical services safely On VCSA: Shell service - control - - status service - control - - stop - - all service - control - - start - - all ...
