Docker push – Error – requested access to the resource is denied

Docker push – Error – requested access to the resource is denied

exact error:  Error: writing blob: initiating layer upload to /v2/shaikabuthagirs/myrepo/blobs/uploads/ in registry-1.docker.io: requested access to the resource is denied

Cause:

While i’m using simply below command to establish connection with hub.docker.com, it is connecting with some other repository instead of docker.io

#docker login

because of the, we are getting above error while trying to push image from server to hub.docker.com

Solution:

We need to login to docker.io repository to fix this issue. So for that we need to mention the repository as well along with #docker login command like below

[ec2-user@ip-172-31-40-126 ~]$ docker login -u shaikabuthagirs -p "Thagir@56" docker.io
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
Login Succeeded!

Now create tag before pushing it to hub and below is the command

[ec2-user@ip-172-31-40-126 nginx]$ docker images
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
REPOSITORY TAG IMAGE ID CREATED SIZE
localhost/mynginx latest 136dabf8f70c 17 minutes ago 196 MB

#docker tag mynginx:latest shaikabuthagirs/nginx:v1

mynginx :latest  ->  my customized image: tag name(This can be like versioning and you can name it as per your own requirement)

shaikabuthagirs/nginx:v1  ->  shaikabuthagirs(My docker hub account name)/nginx(repository which I created in my account):v1(tag name. As I said im using here as version 1)

After tag creation i’m listing images again

[ec2-user@ip-172-31-40-126 nginx]$ docker images
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
REPOSITORY TAG IMAGE ID CREATED SIZE
localhost/shaikabuthagirs/nginx v1 136dabf8f70c 19 minutes ago 196 MB
localhost/mynginx latest 136dabf8f70c 19 minutes ago 196 MB

You can see the tagged image showing now and now we can push it to docker hub using below command

[ec2-user@ip-172-31-40-126 nginx]$ docker push shaikabuthagirs/nginx:v1
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.

Now the image has been pushed into the hub.docker.com and see the below screenshot after the push
