♾ CI/CD Triggers: Cron Job vs. Poll SCM vs. Webhook

These triggers are responsible for initiating the execution of automated build processes based on specific events or schedules.

⏩ Cron Job: A cron job is a scheduled task or command that is executed at specified intervals according to the cron schedule.

⏩ Poll SCM: It is a mechanism used by CI/CD systems to periodically check the source code repository (SCM) for changes.

⏩ Webhook: It is used for automatically triggering actions when certain events occur.

🔣Exploring Kubernetes 🚀 Let's talk about scaling applications!

📌 When it comes to running applications on Kubernetes, we don’t run an individual pod. Because Kubernetes is all about 𝐬𝐜𝐚𝐥𝐢𝐧𝐠 𝐚𝐧𝐝 𝐦𝐚𝐢𝐧𝐭𝐚𝐢𝐧𝐢𝐧𝐠 the availability of pods.

📌 So if you run a single pod, it will be a 𝐬𝐢𝐧𝐠𝐥𝐞 𝐩𝐨𝐢𝐧𝐭 𝐨𝐟 𝐟𝐚𝐢𝐥𝐮𝐫𝐞. Because the Pods themselves cannot be directly scaled.

📌 we need controllers like Replicaset to ensure the desired number of pods are running at all times. Kubernetes has different types of objects associated with pods for different use cases.

The following are important pod-associated objects.
📍𝐑𝐞𝐩𝐥𝐢𝐜𝐚𝐬𝐞𝐭 : To maintain a stable set of Pods replicas running at any given time.
📍𝐃𝐞𝐩𝐥𝐨𝐲𝐦𝐞𝐧𝐭 : To run stateless applications like web servers, APIs, etc
📍𝐒𝐭𝐚𝐭𝐞𝐟𝐮𝐥𝐒𝐞𝐭𝐬 : To run stateful applications like distributed databases.
📍𝐃𝐚𝐞𝐦𝐨𝐧𝐬𝐞𝐭𝐬 : To run agents on all the Kubernetes nodes.
📍𝐉𝐨𝐛𝐬 : For batch processing.
📍𝐂𝐫𝐨𝐧𝐉𝐨𝐛𝐬 : Scheduled Jobs.

☁️ AWS now provides an API to programmatically track free-tier usage.

🔣It provides:
a. actual usage
b. forecasted usage
c. no data if usage is greater than the limit.
d. free-tier limit

Though it can be done via alerts, it is helpful to programmatically limit resource consumption based on the usage data provided and an understanding of what the amount will be after the free tier limit is reached.

Once, I forgot to shut down an EC2 machine and one DocumentDB instance and the final bill was $$$. 😀

🔴 𝐈𝐦𝐩𝐫𝐨𝐯𝐢𝐬𝐢𝐧𝐠 𝐏𝐨𝐝 𝐒𝐭𝐚𝐫𝐭-𝐮𝐩 𝐭𝐢𝐦𝐞 𝐢𝐧 𝐊𝐮𝐛𝐞𝐫𝐧𝐞𝐭𝐞𝐬 𝐭𝐡𝐨𝐮𝐠𝐡 𝐈𝐦𝐚𝐠𝐞 𝐂𝐚𝐜𝐡𝐢𝐧𝐠 ☸️ 🤔

Delay in Pod startup for an application workload can be often attributed to the time taken to pull necessary container images from the registry.

❗️ 𝑰𝒎𝒑𝒂𝒄𝒕
👉 For #Kuberenetes clusters requiring auto-scaling, the delay in pulling a #OCI compliant image can take a longer time, sometimes leading to network timeout (if the image pull doesn't go through the kubelet defined time-period)
👉 Further in situations where application needs to scale out horizontally or process high-speed real-time data, this may have compounding effect on the availability of the application

💥 𝑺𝒐𝒍𝒖𝒕𝒊𝒐𝒏
✅ The probable solution needs to have a cache layer on top of #k8s, so that Kubernetes has a centralized image cache and all nodes “pull” from it
✅ To accelerate image caching, the solutions needs to sit inside #k8s, and all nodes should have the fastest latency towards it.

A handful of #oss projects & tools helps in achieving the objective:
📍 𝐇𝐚𝐫𝐛𝐨𝐫 (https://lnkd.in/dqWZNwnh)
✍️ A pull-through proxy cache performs caching mechanism designed to optimize the distribution and retrieval of container images within a #container registry environment. It acts as an intermediary between clients (such as container runtimes or build systems) and the upstream container registry.

📍 𝐊𝐮𝐛𝐞𝐫𝐧𝐞𝐭𝐞𝐬-𝐢𝐦𝐚𝐠𝐞-𝐩𝐮𝐥𝐥𝐞𝐫 (https://lnkd.in/dXXghvqt)
✍️ Deploys a huge number of containers (one container per image and per node / uses a daemonset for the caching mechanism), to fulfill the caching feature.

📍 𝐓𝐮𝐠𝐠𝐞𝐫 (https://lnkd.in/dcemgYbC)
✍️ Uses a single configuration file, defined through its Helm file values. It does not allow us to segregate “system” configurations (eg : exclude specific images from the caching system) and “users” configurations

📍 𝐊𝐮𝐛𝐞-𝐢𝐦𝐚𝐠𝐞-𝐤𝐞𝐞𝐩𝐞𝐫 (𝐤𝐮𝐢𝐤) (https://lnkd.in/dFCk9jur)
✍️ #Container image caching system for Kubernetes. It saves the container images used by your pods in its own local registry so that these images remain available if the original becomes unavailable.

📍 𝐊𝐮𝐛𝐞-𝐟𝐥𝐞𝐝𝐠𝐞𝐝 (https://lnkd.in/deSUwCbn)
✍️ Kubernetes add-on or operator for creating and managing a cache of container images directly on the worker nodes of a kubernetes cluster. It allows a user to define a list of images and onto which worker nodes those images should be cached (i.e. pulled). As a result, application pods start almost instantly, since the images need not be pulled from the registry

🚨 Mastering Kubernetes Services: ClusterIP, LoadBalancer, NodePort 🚨

In the vast universe of Kubernetes, services play a pivotal role in how applications are exposed to the outside world. Understanding the differences between ClusterIP, LoadBalancer, and NodePort can be key to mastering your Kubernetes deployment strategy.

➡️ClusterIP: Imagine it as a secret club accessible only to members within the Kubernetes cluster. This type of service exposes your app internally, making it reachable exclusively from within the cluster.

➡️LoadBalancer: It's like having a VIP pass to the internet! LoadBalancer exposes your service externally using a cloud provider's load balancer, automatically setting up an external IP address for your app.

➡️NodePort: This is your service's public face. It exposes your app on each Node's IP at a static port, making it accessible externally through <NodeIP>:<NodePort>. It's like having a door on each server that leads directly to your app.

💡 Why does this matter? Understanding these service types can help you design a robust networking strategy for your Kubernetes applications, ensuring they're accessible and secure.
