chefを利用するのにbundle installを辞めて、chefDKを採用

environment

Chef Development Kit: 3.8.14
chef-client version: 14.10.9
berks version: 7.0.7
kitchen version: 1.24.0
inspec version: 3.6.6

background

chefを利用するのに bundle install して利用していたが、依存関係で嵌ると沼から抜け出せない事が多かった。
例えば、 Gemfile で利用したいgemをバージョン固定して、 bundle install 。

bundle install

Bundler could not find compatible versions for gem "chef-zero":
  In Gemfile:
    chef-zero (= 13.0)

    chef (= 14.7.17) was resolved to 14.7.17, which depends on
      chef-zero (>= 13.0)

Bundler could not find compatible versions for gem "mixlib-log":
  In Gemfile:
    chef (= 14.7.17) was resolved to 14.7.17, which depends on
      mixlib-log (>= 2.0.3, ~> 2.0)

    chef-zero (= 13.0) was resolved to 13.0.0, which depends on
      mixlib-log (~> 1.3)

Bundler could not find compatible versions for gem "net-ssh":
  In Gemfile:
    chef (= 14.7.17) was resolved to 14.7.17, which depends on
      net-ssh (~> 4.2)

    chef (= 14.7.17) was resolved to 14.7.17, which depends on
      net-sftp (>= 2.1.2, ~> 2.1) was resolved to 2.1.2, which depends on
        net-ssh (>= 2.6.5)

    chef (= 14.7.17) was resolved to 14.7.17, which depends on
      serverspec (~> 2.7) was resolved to 2.41.3, which depends on
        specinfra (~> 2.72) was resolved to 2.76.9, which depends on
          net-ssh (>= 2.7)

Resolving dependencies... なので、依存関係のgemもバージョン指定しつつ Gemfile へ追加。再度 bundle install 。。。出力されたエラー内容は変わらない。少しずつマイナーバージョンを下げつつ試行錯誤。これは時間が勿体無さすぎる。。

alias張れば良いが、毎回 bundle exec knife とかやるのも何とかしたい。

chefDK

about chefDK

chef-client、Ruby、RubyGems、OpenSSL、Test Kitchen等各種ツールが含まれたDevelopment Kit。
公式に利用が推奨されている(gem installよりも)。
/opt/chefdk C:/opscode/chefdk 等特定ディレクトリに配置し、chefDKのコンポーネントが他アプリケーションへ干渉しないようにする。
gem依存関係が衝突する可能性を減らす。

尚、現時点では 3.8.14 を利用している。

install

f:id:hrt0kmt:20190319212828p:plain

https://downloads.chef.io/chefdk

私は MacOS 10.14 のinstallerをdownload。

chef -v
Chef Development Kit Version: 3.8.14
chef-client version: 14.10.9
berks version: 7.0.7
kitchen version: 1.24.0
inspec version: 3.6.6

set PATH

私は ~/.zshrc にてknifeにalias張ってた為、コメントアウトしてPATH追加。

#alias knife="bundle exec knife"

export PATH=/opt/chefdk/embedded/bin:$PATH

exec zsh

which gem
/opt/chefdk/embedded/bin/gem

which knife
/opt/chefdk/embedded/bin/knife

問題なくknifeも動く。
