🐬 Kubernetes Commands: From Beginner to Advanced for DevOps Engineers

🖥 https://dev.to/prodevopsguytech/kubernetes-commands-for-devops-engineers-124o


🎯 Key Concepts
Before we dive into the commands, let's review some fundamental Kubernetes concepts:

➡️Pod: The smallest and simplest Kubernetes object, representing a single instance of a running process in your cluster.
➡️Node: A worker machine in Kubernetes, which can be a virtual or a physical machine.
➡️Namespace: A way to divide cluster resources between multiple users.
➡️Deployment: A higher-level abstraction that manages a replicated application, ensuring that a specified number of replicas are running.
➡️Service: An abstraction that defines a logical set of pods and a policy by which to access them.
➡️ConfigMap and Secret: Mechanisms to inject configuration data into your applications

💡 Kubernetes vs Docker: What's The Difference?

➡️Docker and Kubernetes are the most common names that one might hear in the field of container technology.

➡️Docker is a runtime and containerization platform that was first introduced in 2013 and brought about a microservices-based computing model.

➡️Kubernetes is a platform that manages and runs containers from multiple container runtimes and supports various container runtimes, including Docker.

Linux's file system is tree-like. The base is "/", with everything else branching off.

➡️ Core Directories:

/bin 🛠: Essential binaries, e.g., bash, ls, grep.
/boot 🚀: Boot items like kernel & bootloader.
/dev 🔌: Device files for connected hardware.
/etc 📜: System configuration files.
/home 🏡: User home directories.
/lib 📚: Shared libraries for programs.
/media 💿: Mounts for removable media.
/mnt 🧲: Temporary mounts.
/opt 📦: Optional software.
/proc 📊: System, process, memory info.
/root 👑: Root user's home.
/sbin 🔧: System admin tools, e.g., init.
/srv 🌐: Data for services.
/tmp 🌡: Temporary files.
/usr 🖥: User software.
/var 🔄: Variable data, logs, temp files.

🐧 Linux Commands:

cd 🚶: Navigate.
ls 📋: List contents.
mkdir 📁: Create folder.
rmdir 🗑: Delete folder.
cp 📤: Copy.
mv 🚚: Move.
rm ❌: Delete.

⚠️ Note: Directories like /bin are crucial. Don't modify!

⚡️How do you back up Jenkins Data and Configurations?

Jenkins requires regular patching and plugin updates.

During these processes, there is a risk of configuration issues, which could potentially lead to a Jenkins crash.

We have experienced this issue several times in projects.

It is very important to have Jenkins backup with its data and configurations.

It includes job configs, builds logs, plugins, plugin configuration, etc.

This blog will cover the following three ways to back up Jenkins data and configurations.

- Using a Think Backup Plugin
- Backup using Disk Snapshots
- Manual Backup
