#Day16:Docker for DevOps Engineers.

🐳 Docker for DevOps Engineers 🚀

Hey there, fellow DevOps Engineers! 👋 Today, we're diving into the wonderful world of Docker, the magical software platform that makes our lives easier when it comes to building, testing, and deploying applications! 🎉

What's Docker all about? 🤔

Well, Docker is like a magic box 📦 that contains everything your application needs to run smoothly. It wraps up your software, libraries, system tools, code, and runtime into neat little packages called containers 📦🏃. These containers are super consistent and can run anywhere, so you don't have to worry about compatibility issues anymore! 💯

Tasks for Today! 📝

First things first, make sure you've already installed Docker . Once you're all set, let's jump into some fun exercises! 🎯

docker run: This command is your best buddy when it comes to starting a new container and playing with it through the command line. Try it out with docker run hello-world 🌟. It's like saying "Hello, Docker!" to the world! 😄

Example:
```
 docker run hello-world
```
Output:
docker inspect: If you want to know all the nitty-gritty details about a container or image, just use docker inspect. It's like peeking inside the container to see what's happening! 🔍

Example:
```
 docker inspect my_container
```
Output: Lots of detailed information about the container 📋
docker port: Need to find out the port mappings for a container? Use docker port. It's like a treasure map 🗺️ that leads you to the right door! 🚪

Example:
```
 docker run -d -p 8080:80 my_web_app
 docker port my_web_app
```
Output:
```
 80/tcp -> 0.0.0.0:8080
```

docker stats: Monitoring is essential, right? Check out docker stats to get a sneak peek at how your containers are using resources. It's like a health checkup for your app! 💓

Example:

 docker stats my_container

Output:

 CONTAINER ID   NAME         CPU %     MEM USAGE / LIMIT     MEM %     NET I/O     BLOCK I/O   PIDS
 abcdef123456   my_container  0.50%     100.2MiB / 1GiB     10.02%    1.5kB / 0B  7.25MB / 0B  20

docker top: Wondering what's happening inside a container? docker top gives you a peek at the processes running inside. It's like being a detective 🔍 in the container world!

Example:
```
 docker top my_container
```
Output:
```
 PID    USER     TIME      COMMAND
 1234   root     0:00      nginx
 5678   root     0:00      node app.js
```
docker save and docker load: When you want to share your awesome images with others, docker save comes to the rescue. It saves an image to a tar archive. And when you want to load an image from a tar archive, use docker load. It's like mailing packages 📦 to your friends!

Example:
```
 docker save -o my_image.tar my_image:latest
 docker load -i my_image.tar
```

That's a wrap! 🎬

Today, we covered some basic but powerful Docker commands. Docker makes life easier by keeping your applications contained and ready to run wherever you need them. 🏃💨 So, go ahead and experiment with these commands to become a Docker expert! You'll find it incredibly handy in your DevOps journey! 🚀
