docker reported Unable to find image 'image-name:tag' locallydocker: Error response from daemon: pull acces​

Yesterday while working with Docker, I encountered problems with pulling images failing. One of the error messages was "Unable to find image 'image-name:tag' locally [docker](/search?q=docker): Error response from daemon: pull access denied for image-name, repository does not exist or may require 'docker login': denied: requested access to the resource is denied. Requested access to the resource is denied". Today I will share how to resolve this issue.

Step 1: Check the mirror name and label
First of all, you need to make sure that the name and label of the mirror you want to pull are correct. Use the following command to check the mirror name and label:

 
    docker images

Make sure that the mirror you want to pull appears in the list and that there are no spelling errors in the name and label.

Step 2: Check Network Connection
If you are experiencing problems when pulling mirrors, it may be due to an unstable network connection. Make sure your network connection is working and try to test it using the following command:

 
    ping google.com

If the network connection is working, you will receive a ping response.

Step 3: Try docker login
Sometimes you will need to login in order to pull a specific image. Try to login using the following command:

 
    docker login

Follow the prompts to enter your username and password, and then try to pull the mirror again.

Step 4: Checking Permissions for Pulling Mirrors
If you are pulling images from a private repository, you may need authorization to access them. Make sure you have the correct permissions. You can try contacting your administrator to get the appropriate authorization.

Step 5: Check the Docker Hub or repository source
If you are unable to pull public images, it may be due to an issue with the Docker Hub or repository source. Make sure that the Docker Hub or repository source is not down and can be accessed normally. You can try visiting the relevant website in your browser to confirm its availability.

Step 6: Check the availability of mirrors
Sometimes, you may not be able to pull a specific version of a mirror. Make sure that the version of the mirror you want to pull exists and is available. You can find this information in the documentation of Docker Hub or repository sources.

To summarize: you can successfully solve the problem of pulling image failure by checking the image name and label, network connection, performing login, checking permissions, checking the repository source and the availability of the image.
