While designed for web development, the PHP scripting language also provides general-purpose use.

Docker Hub is a service provided by Docker forfinding and sharing container images with your team. It is the world’s largest repository of container images with an array of content sources including container community developers, open source projects and independent software vendors (ISV) building and distributing their code in containers.

We and third parties use cookies or similar technologies ('Cookies') as described below to collect and process personal data, such as your IP address or browser information. So it turns out that the Moby Project has a shell script on the Moby GitHub account which can download images from Docker Hub in a format that can be imported into Docker: download-frozen-image-v2.sh; The usage syntax for the script is given by the following: download-frozen-image-v2.sh targetdir image:tag@digest.

It is the world’s largest repository of container images with an array of content sources including container community developers, open source projects and independent software vendors (ISV) building and distributing their code in.

Users get access to free public repositories for storing and sharing images or can choose a subscription plan for private repositories.

Docker Hub provides the following major features:

Download Dockerfile From Docker Hubspot

  • Repositories: Push and pull container images.
  • Teams & Organizations: Manage access to privaterepositories of container images.
  • Official Images: Pull and use high-qualitycontainer images provided by Docker.
  • Publisher Images: Pull and use high-quality container images provided by external vendors.
  • Builds: Automatically build container images fromGitHub and Bitbucket and push them to Docker Hub.
  • Webhooks: Trigger actions after a successful pushto a repository to integrate Docker Hub with other services.

The following section contains step-by-step instructions on how to easily get started with Docker Hub.

Step 1: Sign up for a Docker account

Let’s start by creating a Docker ID.

A Docker ID grants you access to Docker Hub repositories and allows you to explore images that are available from the community and verified publishers. You’ll also need a Docker ID to share images on Docker Hub.

Step 2: Create your first repository

To create a repository:

  1. Sign in to Docker Hub.
  2. Click Create a Repository on the Docker Hub welcome page:
  3. Name it <your-username>/my-private-repo.

  4. Set the visibility to Private.

  5. Click Create.

    You’ve created your first repository. You should see:

Step 3: Download and install Docker Desktop

We’ll need to download Docker Desktop to build and push a container image toDocker Hub.

  1. Download and install Docker Desktop. If on Linux, download Docker Engine.

  2. Sign into the Docker Desktop application using the Docker ID you created in Step 1.

Step 4: Build and push a container image to Docker Hub from your computer

  1. Start by creating a Dockerfile to specify your application as shown below:

  2. Run docker build -t <your_username>/my-private-repo . to build your Dockerimage.

  3. Run docker run <your_username>/my-private-repo to test yourDocker image locally.

  4. Run docker push <your_username>/my-private-repo to push your Docker image to Docker Hub. You should see output similar to:

    Having trouble pushing? Remember, you must be signed into Docker Hub through Docker Desktop or the command line, and you must also name your images correctly, as per the above steps.

  5. Your repository in Docker Hub should now display a new latest tag under Tags:

Congratulations! You’ve successfully:

  • Signed up for a Docker account
  • Created your first repository
  • Built a Docker container image on your computer
  • Pushed it successfully to Docker Hub

Next steps

  • Create an organization to use Docker Hub with your team.
  • Automatically build container images from code through builds.
  • Explore official & publisher images.
  • Upgrade your plan to push additional private Docker images toDocker Hub.

Docker for Visual Studio Code

The Docker extension makes it easy to build, manage, and deploy containerized applications from Visual Studio Code. It also provides one-click debugging of Node.js, Python, and .NET Core inside a container.

Check out the Working with containers topic on the Visual Studio Code documentation site to get started.

The Docker extension wiki has troubleshooting tips and additional technical information.

Installation

Install Docker on your machine and add it to the system path.

On Linux, you should also enable Docker CLI for the non-root user account that will be used to run VS Code.

To install the extension, open the Extensions view, search for docker to filter results and select Docker extension authored by Microsoft.

Overview of the extension features

Editing Docker files

Download Dockerfile From Docker Hub

You can get IntelliSense when editing your Dockerfile and docker-compose.yml files, with completions and syntax help for common commands.

In addition, you can use the Problems panel (Ctrl+Shift+M on Windows/Linux, Shift+Command+M on Mac) to view common errors for Dockerfile and docker-compose.yml files.

Generating Docker files

You can add Docker files to your workspace by opening the Command Palette (F1) and using Docker: Add Docker Files to Workspace command. The command will generate Dockerfile and .dockerignore files and add them to your workspace. The command will also query you if you want the Docker Compose files added as well; this is optional.

The extension recognizes workspaces that use most popular development languages (C#, Node.js, Python, Ruby, Go, and Java) and customizes generated Docker files accordingly.

Docker view

The Docker extension contributes a Docker view to VS Code. The Docker view lets you examine and manage Docker assets: containers, images, volumes, networks, and container registries. If the Azure Account extension is installed, you can browse your Azure Container Registries as well.

The right-click menu provides access to commonly used commands for each type of asset.

You can rearrange the Docker view panes by dragging them up or down with a mouse and use the context menu to hide or show them.

Docker commands

Many of the most common Docker commands are built right into the Command Palette:

You can run Docker commands to manage images, networks, volumes, image registries, and Docker Compose. In addition, the Docker: Prune System command will remove stopped containers, dangling images, and unused networks and volumes.

Docker Compose

Docker Compose lets you define and run multi-container applications with Docker. Visual Studio Code's experience for authoring docker-compose.yml is very rich, providing IntelliSense for valid Docker compose directives:

For the image directive, you can press ctrl+space and VS Code will query the Docker Hub index for public images:

VS Code will first show a list of popular images along with metadata such as the number of stars and description. If you continue typing, VS Code will query the Docker Hub index for matching images, including searching public profiles. For example, searching for 'Microsoft' will show you all the public Microsoft images.

Using image registries

You can display the content and push/pull/delete images from Docker Hub and Azure Container Registry:

An image in an Azure Container Registry can be deployed to Azure App Service directly from VS Code; see Deploy images to Azure App Service page. For more information about how to authenticate to and work with registries see Using container registries page.

Debugging services running inside a container

You can debug services built using Node.js, Python, or .NET (C#) that are running inside a container. The extension offers custom tasks that help with launching a service under the debugger and with attaching the debugger to a running service instance. For more information see Debug container application and Extension Properties and Tasks pages.

Azure CLI integration

You can start Azure CLI (command-line interface) in a standalone, Linux-based container with Docker Images: Run Azure CLI command. This allows access to full Azure CLI command set in an isolated environment. See Get started with Azure CLI page for more information on available commands.
