Nuget 在 Docker 从私人订阅源恢复

Question

I have my application defined by this Dockerfile

FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build

COPY ["MyCertificate.cer", "/usr/local/share/ca-certificates/cacert.crt"]
RUN update-ca-certificates

WORKDIR /src
COPY ["nuget.config", "MyApplication.API/"]
COPY ["MyApplication.API/MyApplication.API.csproj", "MyApplication.API/"]
RUN dotnet restore --configfile MyApplication.API/nuget.config MyApplication.API/MyApplication.API.csproj -v d

COPY . .
WORKDIR "/src/MyApplication.API"
RUN dotnet build "MyApplication.API.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "MyApplication.API.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "MyApplication.API.dll"]

this is my nuget.config

when I try to restore my project that contains 1 package that is coming from my private feed I have this error:

error :   The remote certificate is invalid because of errors in the certificate chain: UntrustedRoot

it looks like that the certificate added into

/usr/local/share/ca-certificates/

it's not recognized. I have tried also different locations:

• /usr/share/ca-certificates/
• /etc/ssl/certs/ca-certificates/

but it does not work.

The certificate that I am using (MyCertificate.cer) I have exported from Chrome and added into my application project tree. The fingerprint into the nuget.config it's also the one that I could see checking the certificate properties.

Answer 1

you need to install the root CA that signed your private Nuget repository public SSL certificate in the container.

PAY ATTENTION 1 make sure that the certificate that you're trying to add to the container (the one that signed your private repository public certificate with) is the one you extract from chrome and save to the container.

PAY ATTENTION 2 also notice that some distributions may need a specific certificate format and so you might need to also convert your .cer file to .crt format (they basically have the same data but are a bit different nevertheless ). Some explanation and here's an example on how to convert the between the files.

To do so for your container (which uses Debian GNU/Linux 10 (buster) ) you need to:

1. copy the rootCA to /usr/local/share/ca-certificates/
2. run in the container update-ca-certificates
