Image Age wrong

[gluehbirnenkopf]

Description of the issue:
When I run gradle build with jib, the images which get produced are 48 years old.
Does not matter if i build on windows, unix or jenkins

$ date
Thu Oct 18 12:50:57 CEST 2018

$ docker images | grep 19.100
registry.eu-de.bluemix.net/XXXXXXX/testservice 19.100.01-SNAPSHOT 46359d31bb35 48 years ago 491MB

Expected behavior:
Image age should be properly set.

Steps to reproduce:
This happens when executing "gradle jib" and "gradle jibDockerBuild"
It does not matter if the image gets pubished locally or in private registry

Environment:
$ ./gradlew -version

Additional Information:

[gluehbirnenkopf]

docker image inspect gives interesting details:
],
"RepoDigests": [],
"Parent": "",
"Comment": "",
"Created": "1970-01-01T00:00:00Z",
"Container": "",
"ContainerConfig": {
"Hostname": "",

the creation date is somehow not acurate.

Seems like this could have something to do with this issue, although we are not using maven/docker plugin at all.

[zy475459736]

I am using Jib's maven-plugin. And I solved the same kind of problem by setting useCurrentTimestamp true in the pom.xml .

[zy475459736]

As far as I know ,not only the Image , but also the resources classes and other things related to your app are having the 1970-01-01 timestamp.
You can find more details searching through the issues.

Or is as designed?

[zy475459736]

As far as I know ,yes. It is designed to be that way.

[victornoel]

@gluehbirnenkopf @zy475459736 this is not a bug, see https://github.com/GoogleContainerTools/jib/blob/master/docs/faq.md#why-is-my-image-created-48-years-ago

[TadCordle]

As mentioned above, this is intended behavior, as we wipe timestamps to maintain reproducibility. You can use the useCurrentTimestamp configuration parameter to set the correct creation date.

It's also worth noting that we are tracking the ability to add a custom timestamp in this issue: #1079
