kubectl get pods --all-namespaces -o jsonpath="{.items[*].spec.containers[*].image}" | sort | uniq -c

➡️ Dive deeper into your Kubernetes clusters with this power command! It lists all container images used by your pods across all namespaces, sorts them, and gives you a count of each unique image. It's a great way to audit and manage your container images and ensure consistency across your deployments.

𝐏𝐫𝐨 𝐓𝐢𝐩: Mastering jsonpath with kubectl can unlock powerful ways to query and manipulate your Kubernetes resources directly from the command line.

☄️ Top 4 Kubernetes Service Types in one diagram.


The diagram below shows 4 ways to expose a Service.

In Kubernetes, a Service is a method for exposing a network application in the cluster. We use a Service to make that set of Pods available on the network so that users can interact with it.

There are 4 types of Kubernetes services: ClusterIP, NodePort, LoadBalancer and ExternalName. The “type” property in the Service's specification determines how the service is exposed to the network.

🔹 ClusterIP
➡️ ClusterIP is the default and most common service type. Kubernetes will assign a cluster-internal IP address to ClusterIP service. This makes the service only reachable within the cluster.

🔹 NodePort
➡️ This exposes the service outside of the cluster by adding a cluster-wide port on top of ClusterIP. We can request the service by NodeIP:NodePort.

🔹 LoadBalancer
➡️ This exposes the Service externally using a cloud provider’s load balancer.

🔹 ExternalName
➡️ This maps a Service to a domain name. This is commonly used to create a service within Kubernetes to represent an external database.

kubectl get pods --all-namespaces --watch-only | grep -v 'Running'

Ever needed to keep an eye on pods that need to be fixed?

Use this live-monitoring kubectl command to watch for real-time updates and immediately identify pods that may need your attention. It filters out the static noise of all the 'Running' pods, so you can focus on the ones that are transitioning states or experiencing issues.

This trick is a lifesaver for Kubernetes administrators who need to ensure high availability and swift issue resolution.

Hello Everyone 👋,

For those considering a switch to DevOps, here are some basic tips to help you get started:

🔢. Familiarize Yourself with DevOps Tools:
Understand the purpose of different DevOps tools such as Jenkins, Ansible, Docker, Kubernetes, Git, and more. Each tool serves a specific function in the DevOps pipeline.

🔢. Grasp the DevOps Workflow:
Gain a solid understanding of the DevOps lifecycle, from development and testing to deployment and monitoring. Know the roles and responsibilities at each stage.

🔢. Scripting Skills are Crucial:
Command at least one scripting language, like Bash or Python. While you don't need to be a hardcore developer, scripting is vital for automation tasks.

🔢. Adaptability is Key:
DevOps is a dynamic field, and tasks can vary widely. Be ready to adapt to new challenges regularly. It's not uncommon to face different issues deploying the same code in different environments, so a problem-solving mindset is crucial.

🔢. Basic Networking Knowledge:
Understand fundamental networking concepts. DevOps often involves working with various systems and networks, so a basic understanding will be beneficial.

🔢. Proficiency in a Cloud Platform:
Be proficient in at least one cloud platform (e.g., AWS, Azure, GCP). Cloud services are integral to modern DevOps practices, and knowing your way around a cloud environment is essential.

🔢. Focus on Proficiency with One Tool Initially:
DevOps encompasses a variety of tools that may serve similar purposes. Instead of trying to learn multiple tools for the same task right away, focus on mastering one tool first.Start by learning the basics and becoming proficient in one tool before exploring others.

🔢. Stay curious:
explore new technologies, and engage with the DevOps community to enhance your skills.


Best of luck on your DevOps journey! 🙂

Discover how your Kubernetes nodes utilize resources and make sure they're not over-committed with our next command of the day.

kubectl describe nodes | grep -A2 -e "^\\s*CPU Requests" -e "^\\s*CPU Limits" -e "^\\s*Memory Requests" -e "^\\s*Memory Limits"

This command will:
- Use 'kubectl describe nodes' to get detailed information about each node.
- Pipe this information to grep.
- Use '-A2' to include the two lines following the match, giving context for the requests and limits.
- Search for patterns related to CPU and Memory requests and limits, which are crucial for understanding the resource allocation and utilization on each node
