Want to **push and pull Docker images** to and from **Docker Hub**? 🚀 In this tutorial, I’ll guide you through the **basics of Docker Hub**, including how to **upload, manage, and pull container images** from a remote repository. By the end of this video, you’ll know how to: ✅ **Push Docker images** to Docker Hub ✅ **Pull Docker images** from Docker Hub ✅ **Tag and manage images** properly ✅ Use Docker Hub as a **private or public repository** — ## **🔹 What You’ll Learn in This Video:** ✔️ How to **set up a Docker Hub account** ✔️ How to **push images** to Docker Hub ✔️ How to **pull images** from Docker Hub ✔️ How to tag Docker images correctly ✔️ How to manage private and public repositories — ## **🔹 Prerequisites** ✔️ **Docker Installed** ([Download Docker](https://www.docker.com/get-started)) ✔️ A **Docker Hub account** ([Sign Up](https://hub.docker.com/)) ✔️ Basic knowledge of **Docker commands** — ## **🔹 Step 1: Login to Docker Hub** First, log in to **Docker Hub** from your terminal: “`bash
docker login
“` Enter your **Docker Hub username and password** when prompted. 💡 If you’re using **two-factor authentication (2FA)**, generate a **personal access token** from Docker Hub instead of using your password. — ## **🔹 Step 2: Pull an Image from Docker Hub** You can pull an official image like **Nginx, Python, or MySQL**: “`bash
docker pull python:latest
“` To check if the image is downloaded, run: “`bash
docker images
“` This lists all **Docker images available locally**. — ## **🔹 Step 3: Build and Tag a Docker Image** If you have a **custom Dockerfile**, build an image and tag it for **Docker Hub**: “`bash
docker build -t yourdockerhubusername/myapp:1.0 .
“` 🔹 `yourdockerhubusername/myapp:1.0` is the image name and tag. 🔹 Always **tag your images** properly before pushing them to Docker Hub. — ## **🔹 Step 4: Push a Docker Image to Docker Hub** Now, push your image to **Docker Hub**: “`bash
docker push yourdockerhubusername/myapp:1.0
“` Once the upload is complete, visit **Docker Hub** to see your image! — ## **🔹 Step 5: Pull Your Image from Docker Hub** On any other system, you can **pull the image** and run it: “`bash
docker pull yourdockerhubusername/myapp:1.0
docker run -d -p 5000:5000 yourdockerhubusername/myapp:1.0
“` This downloads the image from **Docker Hub** and runs it in a container. — ## **🔹 Step 6: Manage Your Docker Hub Repository** To manage your repositories: 🔹 Go to [Docker Hub](https://hub.docker.com/) 🔹 Set images to **public or private** 🔹 Delete or update images as needed — ## **🔹 Common Issues & Fixes** 🔹 **Denied: requested access to the resource is denied** ✅ **Fix:** Ensure you're logged in with `docker login`. 🔹 **Error: unauthorized: authentication required** ✅ **Fix:** Check your credentials and re-authenticate. 🔹 **Image not found when pulling** ✅ **Fix:** Double-check the repository name and tag. — ## **🔹 Who Is This Tutorial For?** ✅ Developers working with **Dockerized applications** ✅ DevOps engineers managing **container registries** ✅ Anyone starting with **Docker containerization** — ## **🔹 More Docker Tutorials:** 📌 **How to Build & Run a Flask App in Docker** → [Watch Now] 📌 **How to Deploy Docker Containers on AWS ECS** → [Watch Now] 📌 **How to Use Docker Compose for Multi-Container Apps** → [Watch Now] — ## **👍 Like, Share & Subscribe!** If this tutorial helped you, please **LIKE, SHARE, and SUBSCRIBE** for more **Docker and DevOps tutorials**! 🚀 💬 Have questions?
