1️⃣.𝙄𝙢𝙖𝙜𝙚𝘽𝙖𝙘𝙠𝙋𝙪𝙡𝙡𝙊𝙛𝙛 :-
We face this issue when the image is not present in registry or the given image tag is wrong.
Make sure you provide correct registry url, image name and image tag.

We might face authentication failures, when image is being stored in a private registry, make sure to create secret with private registry credentials and add created secret in Kubernetes Deployment File to pull docker image.

2️⃣.𝘾𝙧𝙖𝙨𝙝𝙇𝙤𝙤𝙥𝘽𝙖𝙘𝙠𝙊𝙛𝙛 :-
We face this issue when the process deployed inside container not running then the POD will be moved to CrashLoopBackOff.
POD might be running out of CPU or memory, POD should get enough resources allocated that’s cpu and memory for an application to be up and running, to fix that check in Resources Requests and Resources Limits.

3️⃣.𝙊𝙊𝙈 𝙆𝙞𝙡𝙡𝙚𝙙 - 𝙊𝙪𝙩 𝙊𝙛 𝙈𝙚𝙢𝙤𝙧𝙮 :-
We face this issue when PODs tries to utilise more memory than the limits we have set.
We can resolve it by setting appropriate resource request and resource limit.

4️⃣.𝙋𝙊𝘿 𝙎𝙩𝙖𝙩𝙪𝙨 – 𝙋𝙚𝙣𝙙𝙞𝙣𝙜 :-
When nodes might not be ready and required resources like CPU and Memory may not be available in nodes for the PODs to be up and running.

5️⃣.𝙋𝙊𝘿 𝙎𝙩𝙖𝙩𝙪𝙨 – 𝙒𝙖𝙞𝙩𝙞𝙣𝙜 :-
POD will be scheduled to a node but POD won’t be running in scheduled node.
We can fix this by providing correct image name, image tag and authentication to registry.

If service is already created and application is still not accessible, make sure application and service are deployed in same namespace.

7️⃣.𝙋𝙊𝘿 𝙎𝙩𝙖𝙩𝙪𝙨 – 𝙀𝙫𝙞𝙘𝙩𝙚𝙙 :-
We can resolve this by setting appropriate resource requests and resource limits for the PODs and having enough resources in worker nodes.

📢 Complexity by Simplicity - A Deep Dive Into Kubernetes Components


➡️Many software engineers tend to look away from anything related to Kubernetes, even though they might use it daily. At first glance, it seems complex and like a whole new world to dive into. And yeah, it is, but in this blog post, I will go over all of the main components of a Kubernetes cluster and explain what they do in an example.

➡️ By the end of the blog post, you won't be a Kubernetes expert, but you will probably get a good idea of what to look for and how to structure the chaos that Kubernetes seems to be at first.

🚀 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗲 𝗺𝘂𝗹𝘁𝗶𝘀𝘁𝗮𝗴𝗲 𝗽𝗶𝗽𝗲𝗹𝗶𝗻𝗲 𝘀𝗲𝘁𝘂𝗽 𝗶𝗻 𝗔𝘇𝘂𝗿𝗲 🌐

Here's a breakdown of our Dataflow process:

1️⃣ 𝗩𝗶𝘀𝘂𝗮𝗹 𝗦𝘁𝘂𝗱𝗶𝗼 𝗞𝗶𝗰𝗸-𝗼𝗳𝗳:
Developers initiate projects using predefined templates, like the .NET Angular workload. This setup includes an Azure Resource Group project deploying key elements via an ARM template – Azure App Service plan, App Service instance, and Application Insights.

2️⃣ 𝗣𝗶𝗽𝗲𝗹𝗶𝗻𝗲 𝗗𝗲𝗳𝗶𝗻𝗶𝘁𝗶𝗼𝗻 𝘄𝗶𝘁𝗵 𝗬𝗔𝗠𝗟:
A YAML file outlines our multistage pipeline, guiding solution building and publication.

3️⃣ 𝗚𝗶𝘁 𝗣𝘂𝘀𝗵 𝘁𝗼 𝗔𝘇𝘂𝗿𝗲 𝗥𝗲𝗽𝗼𝘀:
Utilizing 'git push' to transfer the solution into Azure Repos repository.

4️⃣ 𝗔𝘇𝘂𝗿𝗲 𝗗𝗲𝘃𝗢𝗽𝘀 𝗡𝗼𝘁𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻:
Triggered by the Git command, Azure DevOps Services dispatches notifications through webhooks.

5️⃣ 𝗟𝗼𝗴𝗶𝗰 𝗔𝗽𝗽 𝗔𝗰𝘁𝗶𝘃𝗮𝘁𝗶𝗼𝗻:
Webhook triggers a logic app to further process the notification.

6️⃣ 𝗟𝗼𝗴𝗶𝗰 𝗔𝗽𝗽 𝗔𝗻𝗮𝗹𝘆𝘀𝗶𝘀:
Logic app assesses the repository branch - whether it's the main branch or a feature branch. In case of a main branch commit, it looks for corresponding pipelines.

7️⃣ 𝗣𝗶𝗽𝗲𝗹𝗶𝗻𝗲 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁:
If a pipeline exists in Azure Pipelines, the logic app uses Azure DevOps Services REST API to update it. Otherwise, it dynamically creates one.

8️⃣ 𝗠𝘂𝗹𝘁𝗶𝘀𝘁𝗮𝗴𝗲 𝗣𝗶𝗽𝗲𝗹𝗶𝗻𝗲 𝗘𝘅𝗲𝗰𝘂𝘁𝗶𝗼𝗻:
This pipeline builds, publishes, and deploys an artifact to Azure resources. The artifact comprises a .NET Angular zip folder for App Service instance deployment and ARM templates with parameter files for Azure infrastructure provisioning.

9️⃣ 𝗦𝘁𝗮𝗴𝗶𝗻𝗴 𝗘𝗻𝘃𝗶𝗿𝗼𝗻𝗺𝗲𝗻𝘁 𝗗𝗲𝗽𝗹𝗼𝘆𝗺𝗲𝗻𝘁:
Artifact deployment to Azure staging environment.

🔟 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗘𝗻𝘃𝗶𝗿𝗼𝗻𝗺𝗲𝗻𝘁 𝗗𝗲𝗽𝗹𝗼𝘆𝗺𝗲𝗻𝘁:
Subsequent deployment to Azure production environment.

Result? ⏱
Reduced labor through automated pipeline provisioning and Azure infrastructure setup. 🛠

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! 🙂

As a DevOps Engineer, you must be aware of 𝐃𝐨𝐜𝐤𝐞𝐫𝐟𝐢𝐥𝐞 𝐁𝐞𝐬𝐭 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐞𝐬:


🔍 Use only and only official and verified images as base image.

🔍 Use light weight docker images for base image like alpine linux image distribution.

🔍 Use docker image version instead of using latest version.

🔍 Install only required packages and softwares into Docker Image.

🔍 Do not have multiple layers of RUN instructions in a Dockerfile, instead have single RUN instruction to install all necessary packages into a docker image using && operator.

🔍 When Dockerfile contains too many layers, try to use multi stage docker file.

🔍 Use .dockerignore file to exclude unnecessary files and directories from docker image in order to reduce docker image size.

🔍 Do not use root user to start docker container, use non root user with least privileges.

🔍 Once docker image is built, make sure docker image is scanned before pushing to Docker Registry.

How to Track Changes Inside Your Docker 🐬 Containers 🚀

If you are struggling to pinpoint file changes inside your Docker containers then try out the powerful "docker container diff" command.

➡️ docker diff allows us to quickly identify all added, modified, or deleted files within a specific container since its creation or last start.

With just one command, we can:

➡️ Track changes for smooth deployments
➡️ Understand the impact of recent modifications
➡️ Troubleshoot issues by detecting root causes
➡️ Audit for unauthorized or unexpected alterations

🖥 Checkout the detailed blog with an example: https://lnkd.in/gx_gWC8N

Prometheus is an open-source monitoring and alerting toolkit designed for reliability and scalability. Below is a an overview of the Prometheus architecture:

🏮 Components:
🖥 Prometheus Server:
- Core for collecting, storing, and querying time-series data.
- It’s pull-based and scrapes metrics from targets at regular intervals.
- Stores data in a local time-series database.
❤️ Metrics (Targets/Exporters):
- Apps or services expose metrics.
- Prometheus scrapes metrics from these targets.
📶 Data Model:
- Time-series data with metric names and labels.
- Example: `http_requests_total{method="GET", status="200"}`.
⚠️ PromQL:
- Query language for time-series data.
- Allows filtering, grouping, and math operations on metrics.
⚠️ Alertmanager:
- Handles alerts from Prometheus.
- Manages notifications and integrates with third-party channels.
☁️ Storage:
- Uses local on-disk storage.
- Data retention policies.
- Data is organized in blocks and compacted over time.

🏮 Workflow:
🌐 Configuration:
- Targets and scrape intervals defined in Prometheus config files.
- Relabeling allows modifying or filtering metrics before storage.
📚 Scraping:
- Prometheus Server scrapes metrics from configured targets.
- Targets expose metrics typically at /metrics endpoint.
☁️ Storage:
- Scraped metrics stored in the local time-series database.
- Data organized by metric name and labels.
📚 Querying:
- Users utilize PromQL to query and analyze stored metrics.
- Grafana or Prometheus's UI visualizes query results.
⚠️ Alerting:
- Prometheus evaluates alerting rules based on queries.
- Alerts sent to Alertmanager if conditions are met.
⚠️ Alertmanager Handling:
- Alertmanager receives alerts and manages their lifecycle.
- Handles deduplication, grouping, and sends notifications to configured channels.
