Cause<\/th>\nExplanation<\/th>\n<\/tr>\n<\/thead>\n
\ud83d\udd12 Private Image<\/strong><\/td>\nYou’re trying to pull an image from a private repo on Docker Hub or another registry, and you’re not authenticated.<\/td>\n<\/tr>\n
\u274c Typo in Image Name<\/strong><\/td>\nThe image name is incorrect or doesn\u2019t exist (e.g., myimage<\/code> instead of username\/myimage<\/code>).<\/td>\n<\/tr>\n
\ud83d\udd10 Not Logged In<\/strong><\/td>\nYou’re trying to access a private registry (Docker Hub, GitHub Packages, AWS ECR, etc.) without running docker login<\/code>.<\/td>\n<\/tr>\n
\ud83c\udf10 Network Issues<\/strong><\/td>\nDocker can’t reach the registry due to firewalls or connectivity problems.<\/td>\n<\/tr>\n

\u2705 How to Fix It<\/span><\/h2>\n

\u2705 1. Check Image Name<\/strong><\/span><\/h3>\n

Make sure the image exists and the name is correct.<\/p>\n

Example of correct public image<\/strong>:<\/p>\n

\n
docker pull nginx
\ndocker pull ubuntu:20.04
\n<\/code><\/div>\n<\/div>\n

Example of correct private image<\/strong>:<\/p>\n

\n
docker pull username\/private-image
\n<\/code><\/div>\n<\/div>\n

If you’re using a custom registry:<\/p>\n

\n
docker pull myregistry.com\/myuser\/myimage:tag
\n<\/code><\/div>\n<\/div>\n
