dockerイメージでpyenvをインストールしたい

$ packer build container.json を実行して、amazonlinuxのdockerイメージを作成しています。

↑を実行した後に、aws/pip/pyenv のコマンドが含まれるスクリプトを実行すると、

aws: command not found

というエラーが出ます。（container.jsonの中でpip install awscliしています）

一時的な対処として、ターミナル上から$ yum install awscliを実行して↑のエラーは解消されても今度は

pyenv: command not found
pip: command not found

というエラーが出ます。

おそらく、container.jsonの

git clone https://github.com/yyuu/pyenv.git {{user `pyenv_dir`}}

でpyenvのインストールができていないのかなと思っています。
（Pythonのバージョンもcontainer.jsonで3.6を指定してインストールしていますが、python --versionでpython 2.7が出力されました。）

いろいろ調べましたがpyenvがインストールできないので、教えていただけると嬉しいです。。

補足：5年ほど前は問題ありませんでしたが、今動かしてみるとエラーが出てしまいます（container.jsonのコードは一部自分で調べて修正しています）。

追記：buildした後に下記のdocker runコマンドでコンテナを起動していますが、cannot execute binary fileというエラーが出たので、7行目のbashをコメントアウトしたのですが、それが影響しているでしょうか？

docker にわざわざ pyenv を入れる意味が分かりません。使いたいバージョンの python イメージを使えば良いのでは…。

パッと見で eval "$(pyenv init --path)" をしてないなと思ったのですが、 {{user `pyenv_dir`}}/shims/pip とパスを直接指定しているし、 pyenv: command not found となるのとは関係ないな、という感想です。 pyenvの初期化の仕方が標準的ではないと思うのですが、それが意図的でやりたいことに対して必要なことだけをしたからこうなっているのか、pyenvのバージョンアップに追随してないだけなのか（そしてそれがエラーの原因になっているのか）、そのあたりの判断が第三者にはできない質問になっていると感じます。
