結論
exec $SHELL -l の代わりに、 . ~/.bash_profile とか . ~/.bashrc を適宜やろう。
. <FilePath> ってなんぞ
. （ドット1文字）っていうコマンドがあります。
bash の場合は、 sourceのエイリアスです。
Vagrant を使う際に、 Shell Provision で、 exec $SHELL -l したいときありますよね。 「anyenv を使って Node.js とかインストールしたい」とか「dotfiles をインストールして、それを読み込んだ前提で何か書きたい」っていうときです。
でも、 各種Provision のなかで exec $SHELL -l しても、 .bash_profile とかの更新分は、反映されません。exec $SHELL したところで、その分の Shell プロビジョンが終了します。
exec $SHELL -l との違い
exec $SHELL -l は、現在のログインシェルを再起動する に近いです。（解説は『シェルを再起動させる簡単な方法』とか読むといいです。）
それに対して、 source は、読み込むファイルを明示しなければいけないので、シェルの起動プロセスとかを把握してないと使えないです。
- 使用する shell に応じて、
sourceするファイルを変える - /etc/profile.d に追加するとかの場合は、そっちを
sourceする
Shell プロビジョンが終了することの確認
以下のようなファイルを準備して、検証しました。
要するに、 Shell プロビジョン内で exec $SHELL はしてはいけない っぽいです。
Vagrantfile
Vagrant.configure("2") do |config|
config.vm.box = "centos/7"
# PID 確認
config.vm.provision :shell, inline: 'ps -f | egrep "$$|PID"'
config.vm.provision :shell, inline: 'ps -f | egrep "$$|PID"'
# anyenv で git 使う
config.vm.provision :shell, inline: "yum -y -q install git"
config.vm.provision :shell, "privileged": false, path: "./anyenv.sh"
###
config.vm.provision :shell, "privileged": false, path: "./nodenv.sh"
