使用dotnet publish -t:PublishContainer推送镜像至DigitalOcean私有仓库遇错

操作背景 #

尝试不通过Docker，直接使用dotnet publish命令将容器镜像推送到DigitalOcean私有镜像仓库。

第一次尝试及报错 #

执行命令：

dotnet publish -t:PublishContainer -p:ContainerRepository=myregistry/imagename -p:ContainerRegistry=registry.digitalocean.com

返回错误：

/Users/user1/.dotnet/sdk/8.0.404/Containers/build/Microsoft.NET.Build.Containers.targets(243,5): error CONTAINER1016: Unable to access the repository 'myregistry/imagename in the registry 'registry.digitalocean.com'. Please confirm your credentials are correct and that you have access to this repository and registry. [/Users/user1/git/myapp/Myproj.csproj]

认证有效性验证 #

已通过docker login registry.digitalocean.com完成仓库认证，且能通过podman成功拉取该仓库内的镜像，证明认证有效：

podman pull registry.digitalocean.com/myregistry/imagename
Trying to pull registry.digitalocean.com/myregistry/imagename:latest...

第二次尝试及报错 #

更换命令参数组合后执行：

dotnet publish -t:PublishContainer -p:ContainerRepository=imagename -p:ContainerRegistry=registry.digitalocean.com/myregistry

返回错误：
