| ## Examples |
| |
| To see how the `docker:latest` image was built: |
| |
| ```console |
| $ docker history docker |

| To see how the `docker:apache` image was added to a container's base image: |
| |
| ```console |
| $ docker history docker:scm |

| |
| ### <a name="format"></a> Format the output (--format) |
| |
| The formatting option (`--format`) will pretty-prints history output |
| using a Go template. |
| |
| Valid placeholders for the Go template are listed below: |
| |
| | Placeholder | Description | |
| |-----------------|-----------------------------------------------------------------------------------------------------------| |
| | `.ID` | Image ID | |
| | `.CreatedSince` | Elapsed time since the image was created if `--human=true`, otherwise timestamp of when image was created | |
| | `.CreatedAt` | Timestamp of when image was created | |
| | `.CreatedBy` | Command that was used to create the image | |
| | `.Size` | Image disk size | |
| | `.Comment` | Comment for image | |
| |
| When using the `--format` option, the `history` command either |
| outputs the data exactly as the template declares or, when using the |
| `table` directive, includes column headers as well. |
| |
| The following example uses a template without headers and outputs the |
| `ID` and `CreatedSince` entries separated by a colon (`:`) for the `busybox` |
| image: |
| |
| ```console |
| $ docker history --format "{{.ID}}: {{.CreatedSince}}" busybox |
| |
| f6e427c148a7: 4 weeks ago |
| <missing>: 4 weeks ago |
| ``` |
| |
| ### <a name="platform"></a> Show history for a specific platform (--platform) |
| |
| The `--platform` option allows you to specify which platform variant to show |
| history for if multiple platforms are present. By default, `docker history` |
| shows the history for the daemon's native platform or if not present, the |
| first available platform. |
| |
| If the local image store has multiple platform variants of an image, the |
| `--platform` option selects which variant to show the history for. An error |
| is produced if the given platform is not present in the local image cache. |
| |
| The platform option takes the `os[/arch[/variant]]` format; for example, |
| `linux/amd64` or `linux/arm64/v8`. Architecture and variant are optional, |
| and if omitted falls back to the daemon's defaults. |
| |
| |
| The following example pulls the RISC-V variant of the `alpine:latest` image |
| and shows its history. |
| |
| |
| ```console |
| $ docker image pull --quiet --platform=linux/riscv64 alpine |
| docker.io/library/alpine:latest |
| |
| $ docker image history --platform=linux/s390x alpine |
| IMAGE CREATED CREATED BY SIZE COMMENT |
| beefdbd8a1da 3 weeks ago /bin/sh -c #(nop) CMD ["/bin/sh"] 0B |
| <missing> 3 weeks ago /bin/sh -c #(nop) ADD file:ba2637314e600db5a… 8.46MB |
| ``` |
| |
| The following example attempts to show the history for a platform variant of |
| `alpine:latest` that doesn't exist in the local image store, resulting in |
| an error. |
| |
| ```console |
| $ docker image ls --tree |
| IMAGE ID DISK USAGE CONTENT SIZE IN USE |
| alpine:latest beefdbd8a1da 10.6MB 3.37MB |
| ├─ linux/riscv64 80cde017a105 10.6MB 3.37MB |
| ├─ linux/amd64 33735bd63cf8 0B 0B |
| ├─ linux/arm/v6 50f635c8b04d 0B 0B |
| ├─ linux/arm/v7 f2f82d424957 0B 0B |
| ├─ linux/arm64/v8 9cee2b382fe2 0B 0B |
| ├─ linux/386 b3e87f642f5c 0B 0B |
| ├─ linux/ppc64le c7a6800e3dc5 0B 0B |
| └─ linux/s390x 2b5b26e09ca2 0B 0B |
| |
| $ docker image history --platform=linux/s390x alpine |
| Error response from daemon: image with reference alpine:latest was found but does not match the specified platform: wanted linux/s390x |
| ``` |
