Docker Commands — Part 1

Docker is a popular platform for developing, shipping, and running applications in containers. Here are some basic Docker commands that you might find useful:

👉 docker version: The docker version command provides information about the Docker client and server versions that are installed on your system. Here's how you can use it:

docker --version

👉 docker info: The docker info command provides detailed information about the Docker system, including containers, images, volumes, networks, and various configuration details. Here's how you can use it:

docker info

👉 docker pull [image_name]: Download a Docker image from a registry (e.g., Docker Hub).

docker pull [OPTIONS] IMAGE_NAME[:TAG]

• [OPTIONS]: This is where you can specify various options to customize the behavior of the pull operation. Common options include --all-tags to pull all tags for the given image, --platform to specify the platform for which to pull the image, etc.
• IMAGE_NAME[:TAG]: This is the name of the Docker image you want to pull from the registry. You can optionally specify a tag to pull a specific version of the image. If you omit the tag, Docker will default to pulling the latest tag.

For example, to pull the nginx image from Docker Hub, you can use:

docker pull nginx
