View Dockerfile content

Dockerfile is a document for how a Docker image is built. There are several ways to view Dockerfile content:

1. Use the Docker CLI

 <code class="sh">docker inspect [image]</code>

For example:

 <code class="sh">docker inspect nginx</code>

This prints the image's metadata, including the Dockerfile content.

2. Use the Vim Editor

 <code class="sh">vim /path/to/Dockerfile</code>

This will open the Dockerfile in the Vim editor.

3. Use the Cat command

 <code class="sh">cat /path/to/Dockerfile</code>

This will print the Dockerfile content in the terminal.

4. Online Dockerfile Viewer

You can upload Dockerfile to an online viewer, for example:

• [Dockerfile Parser](https://github.com/GoogleCloudPlatform/dockerfile-parser#parser-explorer)
• [Dockerfile Lint](https://github.com/GoogleContainerTools/dockerfile-lint#try-out-the-lint)

These tools can format, syntax check and parse Dockerfiles.

5. Use BuildKit

BuildKit is a tool for building Docker images that supports viewing Dockerfile content:

 <code class="sh">buildctl inspect [image]</code>

For example:

 <code class="sh">buildctl inspect nginx</code>
