如何通过 Chef 配置 Bundler？

Question

We use Chef to setup and execute Bundler. We previously run bundle install , in an bash resource with the user and group attributes set to target_user (the bundler operation is intended to be run as this user).

Due to the deprecation of some options (ie. --deployment , --path and --without ), we now need to configure them via bundle config .

However, it seems that when using the same resource configuration, Bundle doesn't work as intended; we get Bundler::SudoNotPermittedError: Bundler requires sudo access to install... , which I suppose is because the configuration file is not stored in the proper place, and/or read.

How should the execute resource be configured? Currently, it's:

# Simplified version
bash "Install gems" do
  code <<~EOF
    bundle config --local deployment true &&
    bundle config --local path /path/to/gems_dir &&
    bundle install --gemfile=/path/to/Gemfile
  EOF

  user "target_user"
  group "target_user"
end

Answer 1

You have this bash resource run as target_user , that's why the error. I think you have 2 options here:

1. Remove the user and group from the resource, then it will be run as root.
2. Add sudo before the every bundle command in the code , and make sure target_user is sudoer with no password.

Answer 2

It turns out that Chef doesn't export the environment (variables) when setting user / group , so if one wants to have a fully preset environment, some variables need to be set manually, via the env attribute.

A minimum preset that accomplishes the task is the following:

bash "Bundle..." do
  code "bundle ..."
  user "user"
  group "user"
  env({
    "HOME"     => "/home/user",
    "USER"     => "user",
    "USERNAME" => "user",
    "PWD"      => "/home/user",
  })
end

There are other variables, but I suppose they aren't significant for the vast majority of the commands.
