"""Configure RubyGems to use the configured RubyRepository entries as its
|
|
gem sources, replacing the default (rubygems.org).
|
|
|
|
RubyGems' own HTTPS client (Net::HTTP, backed by OpenSSL) already trusts
|
|
whatever the `certificates` module installs into the system CA store, so no
|
|
separate certificate configuration is needed here, unlike npm's.
|
|
|
|
Written to RubyGems' system-wide config file, `Gem::ConfigFile::SYSTEM_WIDE_CONFIG_FILE`
|
|
- `$sysconfdir/gemrc`, where `$sysconfdir` is Ruby's own configured
|
|
sysconfdir, not necessarily `/etc`. The official Ruby Docker image builds
|
|
Ruby with `--prefix=/usr/local`, giving `/usr/local/etc/gemrc` (confirmed
|
|
empirically, since Debian's own `sysconfdir` convention of `/etc` does not
|
|
apply to a from-source build). Also written to the more conventional
|
|
`/etc/gemrc`, for any Ruby built with the Debian/`sysconfdir=/etc`
|
|
convention instead (e.g. a distro-packaged `ruby` rather than the official
|
|
image) - harmless to write in both places, since only whichever one a given
|
|
Ruby build actually treats as its sysconfdir is ever read. Unlike a config
|
|
dropped in one specific user's home (`~/.gemrc`, RubyGems' separate "per
|
|
user" level), this applies regardless of which user invokes `gem`.
