| 9 | + |
| 10 | +A **[Docker](https://www.docker.com/) Cheat Sheet** provides a quick reference guide for common Docker commands and concepts. |
| 11 | + |
| 12 | +**Docker** is a containerization platform that allows you to package and distribute applications along with their dependencies in containers. |
| 13 | + |
| 14 | + |
| 15 | + |
| 16 | +> Here's a **Docker cheat sheet with commonly used commands and concepts**: |
| 17 | +
|
| 18 | +## ✅ **Docker Commands** |
| 19 | + |
| 20 | +### **Pull an Image** |
| 21 | + |
| 22 | +Download a Docker image from a registry (e.g., Docker Hub). |
| 23 | + |
| 24 | +```bash |
| 25 | +$ docker pull image_name:tag |
| 26 | +``` |
| 27 | + |
| 28 | +### **List Images** |
| 29 | + |
| 30 | +View a list of locally available Docker images. |
| 31 | + |
| 32 | +```bash |
| 33 | +$ docker images |
| 34 | +``` |
| 35 | + |
| 36 | +### **Run a Container** |
| 37 | + |
| 38 | +Start a new container from an image. |
| 39 | + |
| 40 | +```bash |
| 41 | +$ docker run image_name:tag |
| 42 | +``` |
| 43 | + |
| 44 | +- Add `-d` to run in detached mode. |
| 45 | +- Use `--name` to specify a custom container name. |
| 46 | +- Use `-p` to map ports (e.g., `-p host_port:container_port`). |
| 47 | + |
| 48 | +### **List Containers** |
| 49 | + |
| 50 | +View a list of running containers. |
| 51 | + |
| 52 | +```bash |
| 53 | +$ docker ps |
| 54 | +``` |
| 55 | + |
| 56 | +- Add `-a` to see all containers, including stopped ones. |
| 57 | + |
| 58 | +### **Stop a Container** |
| 59 | + |
| 60 | +Stop a running container gracefully. |
| 61 | + |
| 62 | +```bash |
| 63 | +$ docker stop container_id |
| 64 | +``` |
| 65 | + |
| 66 | +### **Remove a Container** |
| 67 | + |
| 68 | +Delete a stopped container. |
| 69 | + |
| 70 | +```bash |
| 71 | +$ docker rm container_id |
| 72 | +``` |
| 73 | + |
| 74 | +### **Remove an Image** |
| 75 | + |
| 76 | +Delete a Docker image. |

| 99 | +$ docker-compose up |
| 100 | +``` |
| 101 | + |
| 102 | +- Add `-d` to run in detached mode. |
| 103 | + |
| 104 | +### **Stop Services** |
| 105 | + |
| 106 | +Stop containers defined in a `docker-compose.yml` file. |

| 109 | +$ docker-compose down |
| 110 | +``` |
| 111 | + |
| 112 | +### **List Services** |
| 113 | + |
| 114 | +View a list of services defined in the `docker-compose.yml` file. |
| 115 | + |

| 117 | +$ docker-compose ps |
| 118 | +``` |
| 119 | + |
| 120 | +## ✅ **Docker Volumes** |
