The connection docker hub is correct. I just reenter the credentials and Azure pipeline validate it successfully.

The problem seams to be with the path, according to this post, but i can't find a way to specify my docker hub name within this task.

Answer 1

推送是指存储库 [docker.io/library/azuretp]

根据此错误消息行，似乎任务是将映像推送到 Docker 集线器的根级别，这是不允许的。

要解决它，请将任务从更改0.*为2.*

然后，使用以下格式输入您在Docker 存储库页面中列出的 docker 存储库名称dockerhub_namespace/RepositoryName：

对于 YAML，请使用以下示例：

steps:
- task: Docker@2
  displayName: push
  inputs:
    containerRegistry: {service connection name}
    repository: {dockerhub_namespace/RepositoryName}
    command: push
