docker勉強

ブログを書くのは本当に久しぶりのwebシステム担当です^^

 

と言っても阿波銘木の仕事もぼちぼちしています。

今は僕が東京の現場で仕事をしているので思うようには出来ませんが。。。

 

このブログシステムも僕が作りました(ナイショ)。

 

まぁ、エンジニアなんてそんなもんだろうと思うワケですw

 

今日はdockerの勉強をしていました。

OSはCentOSを指定したのですが、まさかまさかのsystemctlで怒られるという、とんでも事件に巻き込まれていますwww

 

いつもはvagrantで開発していたのですがGCPがdockerとの連携を強めたので、これはやらないとダメだと^^;

 

以下はDockerfile

systemctlさえ問題なければすぐに開発環境の構築に成功するのですが、こう言ったアプリケーションはなんだかんだでうまくいかないものです^^;

大きな問題ではないですが。

 

これからはvagrantよりdockerのほうが主流になると信じてdockerで環境を作ろうと思っています。

 

こぼれ話で今までJavaとPHPの開発環境で使用していたVagrantfileも載せておきます。

-----/Vagrantfile-----

 

これだけでは動きません。実際にはvagrantにログインしてサーバ設定してます。

 

 

参考になる方はどうぞ使って下さいwww

 

東京は今日は19度まで上がりました。

 

いよいよ春ですね。

GWに北海道に帰省したら何しようかな^^
