chef-solo with capistrano
chef-solo を capistrano で実行する例
前提
- chef-solo が各ホストにインストール済み
- capistrano をするホストから各ホストに ssh でログインできる
設定
config/deploy.rb でファイルを配置するディレクトリを指定。
set :chef_dir, "/root/chef"
json/base.json で定義された hosts に対して実行される。
{
"hosts": {
"web01": "192.168.1.101",
"app01": "192.168.1.102"
},
"nameservers": [ "192.168.1.1", "8.8.8.8" ]
"run_list": [
"os-defaults"
]
}
json/{hostname}.json が、base.json に上書きされてそれぞれのホストで chef-solo が実行される。
- run_list は base.json + {hostname}.json の内容が連結される
- それ以外の key が重複した場合は {hostname}.json の内容が使用される
特定のホストのみ実行したい場合は cap -S hosts=web01,web02 chef のように引数 -S hosts に "," 区切りの値を指定する。
