Hi @smonov,
Your step numbers are slightly off, perhaps because the lab PDF may be of a prior/outdated course release.
The successful completion of the
tag
command in Lab 3.2 depends on several steps from Lab 3.1: thebuild
step,images
listing, and the containerrun
. Steps 23-28 listed above only prove that the Docker is configured to access the private registry, otherwise they are not related to the successful completion of thesimpleapp
tagging step.Perhaps the image name has a typo. List images again with
sudo docker images
command and ensure that you are attempting totag
the image you find in your local image cache. If it is not found in the cache, then you need to re-build thesimpleapp
image.Regards,
-Chris0 -
Thank you Chris,
Thanks for the help,
For all facing the same issue.simpleapp image wasn't created all seems like I missed to do 3.1 lab. Now it is working since 3.1 is completed
