Issue: GoogleContainerTools/skaffold#6809 Skaffold version: v1.34.0 OS: MacOS

Docker cacheFrom using static docker images

To check this run commands bellow (it works as expected):

export SKAFFOLD_DEFAULT_REPO=<your docker repo> 
source .envrc
skaffold build -p dev --cache-artifacts=false

You need to change the <your docker repo> to the appropriate repository.

export SKAFFOLD_DEFAULT_REPO=<your docker repo>

skaffold build -p branch --cache-artifacts=false

You need to change the <your docker repo> to the appropriate repository.

The error:
