The command to view the history of an image build is indeed using "docker history [image_name]." This command displays a detailed list of all the layers that make up a specified image, along with the creation date, size, and commands that were used to create those layers.

When an image is built, each layer reflects a step in the build process, allowing users to trace back through the changes made to the image over time. This is particularly helpful for understanding how an image was constructed, tracking changes, and troubleshooting issues related to specific layers.

In contrast, the other commands serve different purposes: "docker log [image_name]" would be intended for viewing logs from containers, not image histories. "docker inspect [image_name]" provides detailed information about the image, including configurations but not the layer history specifically. Lastly, "docker version [image_name]" is used to show the Docker version information installed on the machine, and does not relate to image history at all. Thus, using "docker history [image_name]" is the appropriate choice for viewing build history of an image.
