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)

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

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。
