This issue is fixed in v272.0.0 of the gcloud sdk (released on 2019-11-19)

I’ve verified that it works with kaniko versions v0.13.0 and v0.14.0

I am still having this issue, what is the solution?

I’m following the official documentation: https://cloud.google.com/build/docs/kaniko-cache

We are working on a fix for this issue.

As a potential work around you can try using v0.12.0 image of kaniko gcloud config set builds/kaniko_image gcr.io/kaniko-project/executor:v0.12.0

I have the same issue, kaniko is enabled with gcloud config set builds/use_kaniko True as per docs here: https://cloud.google.com/cloud-build/docs/kaniko-cache without an explicit cloudbuild.yaml.

I’m using a cloudbuild.yaml and running into the same issue.

As a quickfix I’m using --cache=true

EDIT:

only --cache is working too
