Docker is an open-source platform that gives developers everything they need to create, package, and deploy applications in a streamlined way. With Docker’s container technology, you can bundle your applications and all their dependencies into a single, self-contained unit that can easily be moved across different platforms and run seamlessly in containers. However, to make the most of what Docker offers, you must get comfortable with its command-line interface (CLI). In this article, we’ll walk you through the must-know Docker commands every developer and system administrator should have in their toolkit.

Why Do You Need Docker Commands?

Docker commands are essential for managing and interacting with Docker containers and images. It includes creating, running, stopping, deleting containers, and creating images from Dockerfiles. In addition, it enables the ability to run tasks such as listing live containers, checking container status, transferring files between the host machine and containers, and managing Docker networks and Docker volumes. In use, it is impossible to achieve the desired state of utilizing Docker in containerizing applications, achieving portability and making it easy to deploy it across various platforms.

How to Use Docker Commands?

Here are some common ways to use Docker commands:

1. Run a container: docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...] This command creates and starts a new container from the specified image.
2. List running containers: docker ps Lists all currently running containers.
3. ഒരു കണ്ടെയ്നർ നിർത്തുക: docker stop CONTAINER_ID Stops the running container specified by its ID or name.
4. Remove a container: docker rm CONTAINER_ID Removes the stopped container from the system.
5. Pull an image: docker pull IMAGE[:TAG|@DIGEST] Downloads the specified image from a registry (e.g., Docker Hub).
6. Build an image: docker build [OPTIONS] PATH | URL | - Builds a new image from the instructions in a Dockerfile.
7. ചിത്രങ്ങൾ ലിസ്റ്റ് ചെയ്യുക: docker images Lists all available images on the local system.
8. Remove an image: docker rmi IMAGE[:TAG|@DIGEST] Removes the specified image from the local system.
9. Run a command in a container: docker exec [OPTIONS] CONTAINER_ID COMMAND [ARG...] Runs the specified command within a running container.
10. View logs: docker logs CONTAINER_ID Fetches the logs of the specified container.

These are just a few examples. Below, I have provided a list of docker commands. You can also explore more commands and their options by running docker --help അല്ലെങ്കിൽ റഫർ ചെയ്യുക ഔദ്യോഗിക ഡോക്കർ ഡോക്യുമെന്റേഷൻ.

docker login [OPTIONS] [SERVER]

ഡോക്കർ നിരാകരിക്കുക

ദി docker commit command creates a new image from a container’s changes. This is useful for capturing the state of a running container and creating a new image based on that state.

ഉപയോഗം

docker commit [OPTIONS] <container_name_or_id> [REPOSITORY[:TAG]]

ഡോക്കർ പുഷ്
