The format of the blog is like it starts with the scenario, then challenges and finally the solution.

Scenario

A development team is already using a Kubernetes cluster for their applications and now wants to run their CI/CD jobs on the same cluster for better scalability and resource efficiency. However, they face key Challenges

Challenges

1. 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐑𝐢𝐬𝐤𝐬 𝐰𝐢𝐭𝐡 𝐊𝐮𝐛𝐞𝐂𝐨𝐧𝐟𝐢𝐠: They want to connect GitLab pipelines to Kubernetes without storing KubeConfig files, as it poses a security risk.
2. 𝐁𝐮𝐢𝐥𝐝𝐢𝐧𝐠 𝐃𝐨𝐜𝐤𝐞𝐫 𝐈𝐦𝐚𝐠𝐞𝐬: With Kubernetes moving away from Docker, they need an alternative to Docker-in-Docker (DinD) to build images within the CI/CD pipeline.
3. 𝐌𝐮𝐥𝐭𝐢-𝐄𝐧𝐯𝐢𝐫𝐨𝐧𝐦𝐞𝐧𝐭 𝐃𝐞𝐩𝐥𝐨𝐲𝐦𝐞𝐧𝐭𝐬: They need a simplified way to deploy across dev, test, and prod using a single Helm chart, avoiding complex configurations.
4. 𝐂𝐨𝐝𝐞 𝐐𝐮𝐚𝐥𝐢𝐭𝐲 𝐚𝐧𝐝 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲: Automated tools for code linting and vulnerability scanning are required to maintain high standards across environments.

As a Devops engineer you are tasked to find an integrated solution to overcome these challenges and streamline their CI/CD process.

Solution

In my latest video, I showcase how to implement a complete 𝐂𝐈/𝐂𝐃 pipeline with 𝐆𝐢𝐭𝐋𝐚𝐛 𝐊𝐮𝐛𝐞𝐫𝐧𝐞𝐭𝐞𝐬 𝐑𝐮𝐧𝐧𝐞𝐫𝐬, integrating top DevOps tools like MegaLinter, Kaniko, Trivy, Helm, and the powerful 𝐆𝐢𝐭𝐋𝐚𝐛 𝐊𝐀𝐒 𝐀𝐠𝐞𝐧𝐭.
