AspNetCore:2.1 not found

Question

Created a new .NET CORE 2.1 (preview) web app. Running it in local docker with Linux container I am getting compiler error:

Error Building blobtest
Service 'blobtest' failed to build: manifest for microsoft/aspnetcore:2.1 not found.

My dotnetversion
C:\WINDOWS\system32>dotnet --version 2.1.300-preview2-008530

Answer 1

I had this issue as well. I thought I'd update this post to show the fix here. Thanks to Marius Bidireac for the link to the resource.

Here is an excerpt from the original docker file

FROM microsoft/aspnetcore:2.0 AS base

FROM microsoft/aspnetcore-build:2.0 AS build

Here is an excerpt from the corrected docker file

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base

FROM microsoft/dotnet:2.1-sdk AS build

Answer 2

They have changed the repo for .NET Core 2.1 onwards to microsoft/dotnet. Change your FROM statement to reference microsoft/dotnet using the following tags:

• 2.1-sdk
• 2.1-aspnetcore-runtime
• 2.1-runtime
