"""Configure NuGet to use the configured NuGetRepository entries as its
|
|
package sources, replacing the default (nuget.org).
|
|
|
|
NuGet's own HTTPS client (.NET's HttpClient, backed by OpenSSL on Linux)
|
|
already trusts whatever the `certificates` module installs into the system
|
|
CA store, so no separate certificate configuration is needed here, unlike
|
|
npm's.
|
|
|
|
Microsoft documents a "Computer"-wide config file for this purpose,
|
|
`/etc/opt/NuGet/Config` on Linux (or `$NUGET_COMMON_APPLICATION_DATA/NuGet/Config`
|
|
should that variable be set) - but the .NET SDK does not actually read it in
|
|
practice (confirmed empirically; a known, still-open upstream gap, see
|
|
dotnet/sdk#12674), so it would silently have no effect. This instead writes
|
|
the "user" level config, `~/.nuget/NuGet/NuGet.Config` (the location the
|
|
.NET CLI itself uses; Mono/NuGet.exe use `~/.config/NuGet/NuGet.Config`
|
|
instead). This tool targets Docker images, which are built and run as root,
|
|
so `~` is assumed to be `/root`, exactly like a fresh dotnet install does
|
|
when not overridden - the same tradeoff the `php` module's Composer config
|
|
already accepts. A `<clear />` element is included so the configured
|
|
sources fully replace nuget.org rather than being merged alongside it,
|
|
matching every other package-manager module's behaviour.
|
|
|
|
The same file is additionally written under each configured `--user`'s own
|
|
home directory (`context.users`), since a non-root user invoking `dotnet`
|
|
reads its config from there instead.
