推送镜像到DockerHub

我们推送镜像到DockerHub时会遇到没有访问资源权限的问题

requested access to the resource is deni
ed

这是因为dockerhub不知道是谁推送的镜像，所以推送不上去。
解决这个问题：
1.检查有没有登录dockerhub

D:\study\ispp-return>docker login
Authenticating with existing credentials...
Login Succeeded

Logging in with your password grants your terminal complete access to your accou

For better security, log in with a limited-privilege personal access token. Lear

2.给自己的镜像打tag并推送

docker tag ffcs/springboot_demo 19950805/springboot_demo:01
docker push 19950805/springboot_demo:01

打tag的格式为
docker tag [镜像] [dockerhub的用户名]/[仓库里的镜像名]:[标签]
现在就可以推送了
docker push 19950805/springboot_demo:01
