openshift4.3でYAMLからプロジェクトを作成する②(失敗)

# はじめに

前回、openshift4.3.1から出力したテンプレートをそのままYAMLでAddしようとしたらエラーとなった件
試しにカタログからアクセスできるSample repositoryのテンプレートで試してみることにしました。

前回の失敗談:
　- [openshift4.3でYAMLからプロジェクトを作成する(失敗)](https://qiita.com/imp555sti/items/d615d32fc4d4378950aa)

# カタログのPHPからSample repositoryにアクセスする

＋AddのFrom CatalogからPHPテンプレートを呼び出します。

## Sample repositoryにアクセスする
ではSample repositoryにアクセスしてみましょう。

Sample repository:
　- [https://github.com/sclorg/cakephp-ex.git](https://github.com/sclorg/cakephp-ex.git)

## テンプレート(YAML/JSON)を確認する

Sample repositoryにある`openshift/templates`にアクセスします。
これをRAWでCopyしてopenshiftのYAMLでインポートしてみます。
