To see how the docker:latest image was built:
$ docker history docker IMAGE CREATED CREATED BY SIZE COMMENT 3e23a5875458 8 days ago /bin/sh -c #(nop) ENV LC_ALL=C.UTF-8 0 B 8578938dd170 8 days ago /bin/sh -c dpkg-reconfigure locales && loc 1.245 MB be51b77efb42 8 days ago /bin/sh -c apt-get update && apt-get install 338.3 MB 4b137612be55 6 weeks ago /bin/sh -c #(nop) ADD jessie.tar.xz in / 121 MB 750d58736b4b 6 weeks ago /bin/sh -c #(nop) MAINTAINER Tianon Gravi <ad 0 B 511136ea3c5a 9 months ago 0 B Imported from -
To see how the docker:apache image was added to a container's base image:
$ docker history docker:scm IMAGE CREATED CREATED BY SIZE COMMENT 2ac9d1098bf1 3 months ago /bin/bash 241.4 MB Added Apache to Fedora base image 88b42ffd1f7c 5 months ago /bin/sh -c #(nop) ADD file:1fd8d7f9f6557cafc7 373.7 MB c69cab00d6ef 5 months ago /bin/sh -c #(nop) MAINTAINER Lokesh Mandvekar 0 B 511136ea3c5a 19 months ago 0 B Imported from -
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 will either output the data exactly as the template declares or, when using the table directive, will include 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:
$ docker history --format "{{.ID}}: {{.CreatedSince}}" busybox f6e427c148a7: 4 weeks ago <missing>: 4 weeks ago
