Docker error – denied: requested access to the resource is denied

Today in this article, we will see the resolution for the docker error “denied: requested access to the resource is denied”.

Issue Description

Docker push commands give access denied error as below,

denied: requested access to the resource is denied

Resolution

While pushing an image or a repository to a docker remote registry, you might get an error that the requested access to the resource is denied.

In such scenarios, please make sure to follow the below steps to correct the issue.

Root cause

• Attempting to pull or push an image from or to a container registry without proper authentication or permissions could cause the access denied error.

To fix this issue, you need to ensure that you have the appropriate access rights to the container registry you are trying to interact with.

Login issues could occur due to multiple reasons for example,

Other root causes are also due to,

• TAG missing for the docker containers, or

• Missing the fully qualified name of your docker while performing docker operations.

Resolutions

Please login to the correct Docker hub account

docker login <registry-url>

Validate authentication or permissions while pulling or pushing an image from or to a container registry

For any additional issues please perform the below,

Create a TAG that refers to the Source TAG

Let’s first check the available images in your local and then tag them appropriately.

Above I have an image “thecodebuzzapp” with TAG as “latest“.

This image I would like to push this to the docker hub.

Let’s use the below command to tag our target image with the source tag below

Command – Create a TAG

docker tag local-image:tagname new-repo:tagname

Where,

• local-image – Is the name or Id of the local image. In the above example “thecodebuzzapp” is the image name.

• tagname – TAG name used for the local image. In the above example “latest” is the TAG name.

• new-repo – This is the target/remote repository name where you would like to push the docker local image

• tagname – TAG name used for target/remote image

Before you can push an image to your docker registry, you must tag it with the

fully qualified name of your docker login server.

Example – Associate TAG

docker tag thecodebuzzapp:latest firstthecodebuzz/myfirstapp:coolapp

To avoid any issues, keep the names in lowercase and try using fully qualified name of docker login server

Push the image to the remote Docker Hub

Let’s now push the image to the docker repository using the below command,

Command – Push Image to Remote docker

docker push new-repo:tagname

Example -Push Image to Remote docker

docker push firstthecodebuzz/myfirstapp:coolapp

Finally, you shall see your docker image successfully pushed,

Still an issue – Additional checks

• Check the necessary access permissions on the container registry are acquired. Ensure that you have the appropriate permissions based on your intended actions (pull or push).

• Verify Registry URL: Ensure that you are using the correct URL for the container registry.

• Check for Proxy Settings (if applicable): If you are behind a corporate firewall or using a proxy server, check if Docker is configured to work with the proxy.

• Clear Docker Cache: Sometimes, Docker cache can cause authentication issues. Try clearing the Docker cache
