dotnet error [The specified framework 'Microsoft.AspNetCore.App', version '2.2.0' was not found.] & [NETSDK1061]－FIVE

以下文章為我遇到把dotent core webapi專案包成docker出現的問題

我原本的CI build code如下

# 輸入 rhel.7-x64 Docker Image
> dotnet restore -r rhel.7-x64
> dotnet publish --no-restore -f netcoreapp2.2 -c Release -r rhel.7-x64 --self-contained false /p:PublishWithAspNetCoreTargetManifest=false
> docker build -t pushproxy:v1 .

但是執行後，卻出現如下情況....

The specified framework 'Microsoft.AspNetCore.App', version '2.2.0' was not found.
- Check application dependencies and target a framework version installed at:
/opt/rh/rh-dotnet22/root/usr/lib64/dotnet/
- Installing .NET Core prerequisites might help resolve this problem:
http://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409
- The .NET Core framework and SDK can be installed from:
https://aka.ms/dotnet-download
It was not possible to find any compatible framework version

真是見鬼了!!

完全按照openshift官網的說明文字居然會執行失敗

經過半天的努力後....我放棄了晚上先去打球

今天早上重新整理思緒~~

使用 dotnet --info 去查CI SDK docker image的環境到底是?

microsoft/dotnet:2.2-sdk

$ dotnet --info
.NET Core SDK (reflecting any global.json):

  Microsoft.AspNetCore.App 2.2.1 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 2.2.1 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

然後再看一下我自己電腦內的SDK環境

dotnet --info

似乎發現原因了!!!

總之就重新到官網下載最新的sdk

然後問題就解決啦

才怪

restore指令過關

但publish反而就發生錯誤囧

dotnet publish --no-restore -f netcoreapp2.2 -c Release -r rhel.7-x64

感謝網路上中國人的幫忙

.csproj檔案加入以下資訊，強制使用最新的SDK去執行

節錄.csproj內容

<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>netcoreapp2.2</TargetFramework>
<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
<TargetLatestRuntimePatch>true</TargetLatestRuntimePatch>
