I believe image names (path, not tag) can only contain lowercase letters

Are you sure your Docker username is Shy123789 and not shy123789? try that as the image path

5

I tried with lowercase letters also

PS C:\Users\LAPSAdmin\dockerdotnet\dotnetcore-samples\aspnetapp> docker image push shy123789/aspnetapp:v1
The push refers to repository [docker.io/shy123789/aspnetapp]
An image does not exist locally with the tag: shy123789/aspnetapp
PS C:\Users\LAPSAdmin\dockerdotnet\dotnetcore-samples\aspnetapp> docker image push shy123789/aspnetapp:v2
The push refers to repository [docker.io/shy123789/aspnetapp]

Of course, your image is tagged Shy123789/aspnetapp:v1, you didn’t change the image tag to shy123789/aspnetapp:v1, so Docker has no idea what image you’re trying to push

7

I changed now but still i see as below

PS C:\Users\LAPSAdmin\dockerdotnet\dotnetcore-samples\aspnetapp> docker image push Shy123789/aspnetapp:v1
The push refers to repository [Shy123789/aspnetapp]

You are still using a CAPITAL S

Yes, but either way it is giving error.

We’re running in circles, I told you your problems, you did nothing to fix them

First, you tried pushing an image with a capital letter - That will not work

Then you tried pushing the image named correctly, BUT YOU DID NOT TAG THE IMAGE

Then you went back to error 1, and now we’re again at error 2

TAG THE IMAGE
docker tag Shy123789/aspnetapp:v1 shy123789/aspnetapp:v1
Then push it!

Thank you, I have corrected that step, and it worked.

My apologies for losing my temper, I should not visit the forums first thing in the morning :sweat_smile:

Glad it worked out

That’s alright. It took me some time to comprehend it. There’s no need to worry :slight_smile:
