[redmine][slack]redmineとslackの連携機能を検証する（その１）

最近、slackの利用を考えて、機能の検証を実行することにしました。
他のタイムライン共有/チャットツールに比べ、他のツールとの連携機能が充実しているところがポイントです。

はじめは、redmineです。

まずは、pluginの導入です。
説明を読むと、バージョン３．２は未対応のようなので、まずはbitnami-redmineのバージョン２の最新版（2.6.9)をdockerコンテナで作成し、稼働検証です。
（こんなとき、dockerは便利ですね！）

（bitnami-redmine-stackを変更すれば利用できます）
githubからpluginをcloneしてrakeしますが、上手く行きません。

rake aborted!
LoadError: No such file to load -- httpclient
・・・

bundle installで実行しても、結果は同じ。

[root@docker-con htdocs]# bundle install

いろいろとGoogle先生に聞きながら、
1.htdocsのGemfileにgem "httpclient"を追記
2.yum install gcc -y -qの実行：bitnai-stackでは開発ツールが省略されている
3.bundle install --no-deployment --without development testの実行
で行けることを確認

[root@dokcer-con htdocs]# vi Gemfile

Warning: this Gemfile contains multiple primary sources. Using `source` more than once without a block is a security risk, and may result in installing unexpected gems. To resolve this warning, use a block to indicate which gems should come from the secondary source. To upgrade this warning to an error, run `bundle config disable_multisource true`.
Your Gemfile lists the gem httpclient (>= 0) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of just one of them later.
Warning: the running version of Bundler is older than the version that created the lockfile. We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

これで、bitnami-redmine-stackを再起動して、pluginを確認したスクリーンショットが最初のもの。

その後、slackとの連携を設定して稼働確認して、まずは第一段階終了。
