Error when generating Dockerfile

Describe the problem/bug When executing the build.sh file an error emerges that does not let me create the Dockerimage.

Additional information I have tried to run it with the following .NET versions:

• 2.1
• 2.2
• 3.1

Logs (if applicable)

/usr/local/share/dotnet/sdk/2.1.804/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.TargetFrameworkInference.targets(137,5): error NETSDK1045: El SDK de .NET actual no admite el destino .NET Core 3.1. Use el destino .NET Core 2.1 u otro inferior, o bien una versión del SDK de .NET que admita .NET Core 3.1. [/Users/sokardys/workspace/rookielabs/btcpayserver/BTCPayServer.Data/BTCPayServer.Data.csproj]

To Reproduce Steps to reproduce the behavior:

1. Clone the repo
2. Run thebuild.sh file
3. See error

Expected behavior Dockerimageis generated without errors.

Actual behavior It pops up an error. No Dockerimage is generated

For example:

# Build btcpayserver
# https://raw.githubusercontent.com/btcpayserver/btcpayserver/v1.0.3.164/amd64.Dockerfile
DOCKERFILE="amd64.Dockerfile"
# https://raw.githubusercontent.com/btcpayserver/btcpayserver/v1.0.3.164/arm32v7.Dockerfile
[[ "$(uname -m)" == "armv7l" ]] && DOCKERFILE="arm32v7.Dockerfile"
# https://raw.githubusercontent.com/btcpayserver/btcpayserver/v1.0.3.164/arm64v8.Dockerfile
[[ "$(uname -m)" == "aarch64" ]] && DOCKERFILE="arm64v8.Dockerfile"
echo "Building btcpayserver/btcpayserver:1.0.3.164"
git clone https://github.com/btcpayserver/btcpayserver btcpayserver
cd btcpayserver
git checkout v1.0.3.164
cd "$(dirname $DOCKERFILE)"
docker build -f "$DOCKERFILE" -t "btcpayserver/btcpayserver:1.0.3.164" .
cd - && cd ..

You can check the relevant dockerfile directly to see how to build each image in details outside of docker if you need to.

On the check and cross marks we link to each dockerfile on https://github.com/btcpayserver/btcpayserver-docker#support

@NicolasDorier Maybe I am not expressing well the issue. My end-goal is being able to generate a Dockerfile in the same conditions as https://hub.docker.com/r/btcpayserver/btcpayserver.

What are the steps to successfully execute docker build.

Side note

How can I reach to the point where I can compile these 3 architectural builds?

1. https://github.com/btcpayserver/btcpayserver/blob/master/arm64v8.Dockerfile

2. https://github.com/btcpayserver/btcpayserver/blob/master/arm32v7.Dockerfile

3. https://github.com/btcpayserver/btcpayserver/blob/master/amd64.Dockerfile

Build.sh does not create a docker image.

docker build -f amd64.Dockerfile . is all it takes. No dependency on dotnet either when doing this.
