docker push give me that error: “an image does not exist locally with the tag”

Question

I'm trying to push an image that is hosted in another project with that command:

docker login [first account with service-account]
docker pull gcr.io/xxx/xxx/xxx:1.0.0
docker login [other service-account]
docker push gcr.io/yyy/yyy/yyy:1.0.0

and that give me that error: An image does not exist locally with the tag: gcr.io/yyy/yyy/yyy

How I can fix it? I altro tried to tag the image locally but has now worked

Answer 1

You can simply tag your XXX Docker image as YYY, for example:

# Pull image XXX
docker login [first account with service-account]
docker pull gcr.io/xxx/xxx/xxx:1.0.0

# Tag it as YYY
docker tag gcr.io/xxx/xxx/xxx:1.0.0 gcr.io/yyy/yyy/yyy:1.0.0

# Push it on the other account
docker login [other service-account]
docker push gcr.io/yyy/yyy/yyy:1.0.0

Your command fails because Docker does not recognize that gcr.io/yyy/yyy/yyy:1.0.0 is the same as gcr.io/xxx/xxx/xxx:1.0.0 - you must specifically tell-it so by tagging such as above.
