这是我试图推送到 docker hub 的图像
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
smiduthu/has_test latest 2e0d0ba5412a 27 minutes ago 765.4 MB
我在做docker push smiduthu/has_test。
尝试推送图片时出现以下错误
The push refers to a repository [smiduthu/has_test] (len: 1)
2e0d0ba5412a: Image push failed
FATA[0002] Error pushing to registry: token auth attempt for registry https://registry-1.docker.io/v2/: https://auth.docker.io/
=repository%3Asmiduthu%2Fhas_test%3Apull%2Cpush&service=registry.docker.io request failed with status: 401 Unauthorized
问题是什么 ？
