bundle.lock and production deploy

the application along with the specific versions used. This means your
app will only use the versions mentioned here and no others, even if
updates for those gems are available. When you are deploying your
application to staging or production, your application is going on a
separate server so you want to make sure all the same versions of the
gems are installed there as your local development system, so you
should use bundle lock in this situation. So does that mean when you
use capistrano to do a production deploy, and you always run bundle
install during a deploy, should you run "bundle lock" before you run
"bundle install" during the deploy process to production to make sure
that gems aren't updated in production if they are not updated in
development computer?

Bundle lock was deprecated something like 3 years ago. Bundle install does it for you
