Atlassian Stash is the Git code management solution for enterprise teams. It allows everyone in your organisation to easily collaborate on your Git repositories, while providing enterprise-grade support for:

• ユーザー認証
• リポジトリのセキュリティ
• 既存のデータベースと開発環境を統合します。

This page describes best practice for using Stash in enterprise environments, that is with 500+ user licenses. Of course, much of this information is also applicable to other Stash installations.

Stash をホストするためのプラットフォーム要件

Stash は Windows、Linux および Mac システム上で実行できますが、エンタープライズ用には Linux のみを推奨し、サポートしています。この推奨は、Stash を使用した当社独自のテストや経験に基づいています。

See the Supported platforms page for details of the supported versions of Java, external databases, web browsers and Git.

Stash に関するパフォーマンスの考慮事項

一般的に、Stash は非常に安定性が高く、メモリ消費量が低い製品です。Git ホスト操作 (特に複製) 以外、スケーラビリティの制限はありません。当社ではこれが製品のスケーラビリティの制限であると把握しています。制限は、システムのコアの数に比例します。

As an example, data collected from an internal Stash instance indicate that for a team of approximately 50 developers, with associated continuous integration infrastructure, we see a peak concurrency of 30 simultaneous clone operations and a mean of 2 simultaneous clone operations. We conservatively expect that a customer with similar usage patterns would be capable of supporting 1000 users on a machine with 40 cores and a supporting amount of RAM. While we expect a peak concurrency larger than 40, Stash is designed to queue incoming requests so as to avoid overwhelming the server. See Stash production server data for data from the Stash production instance we run internally at Atlassian.

See Scaling Stash for more information about Stash performance and hardware requirements.

See Scaling Stash for Continuous Integration performance for information specific to Stash performance when CI tools poll Stash for changes.

Stash を使用した高可用性

If Stash is a critical part of your development workflow, maximizing Stash availability becomes an important consideration. Please see High availability for Stash for the background information you need to set up Stash in a highly available configuration. 

Setting up Stash in a production environment

Stash を本番環境またはエンタープライズ環境でセットアップするときは、以下の項目の設定を強く推奨します:

Stash を専用ユーザーとして実行する

• 本番環境の場合、Stash は権限が制限された専用ユーザーアカウントから実行する必要があります。「専用ユーザーで Stash を実行する」を参照してください。

Stash をサービスとしてインストールする

• See Running Stash as a Linux service or Running Stash as a Windows service.

外部データベースを使用する

• For production environments Stash should use an external database, rather than the embedded database. Set up your external DBMS (for example MySQL) before starting Stash for the first time. This allows you to connect Stash to that DBMS using the Setup Wizard that launches when you first run Stash. See Connecting Stash to an external database.

既存のユーザーディレクトリへ接続する

• Connect Stash to your existing user directory (for example Active Directory). See External user directories.

Stash ホームディレクトリを保護する

• For production environments the Stash home directory should be secured against unauthorised access. See Stash home directory.

Stash を HTTPS で保護する

• Access to Stash should be secured using HTTP over SSL, especially if your data is sensitive and Stash is exposed to the internet. See Securing Stash with HTTPS.

Git リポジトリへの SSH アクセスを有効にする

• Enable SSH access for your Stash users to Git repositories in Stash so that they can add their own SSH keys to Stash, and then use those SSH keys to secure Git operations between their computer and the Stash server.  See Enabling SSH access to Git repositories in Stash.

Stash へのコンテキストパスを変更する

• If you are running Stash behind a proxy, or you have another Atlassian application (or any Java web application), available at the same hostname and context path as Stash, then you should set a unique context path for Stash. See Moving Stash to a different context path.

本番環境で Stash を管理する

Stash のアップグレード

• For production environments we recommend that you test the Stash upgrade on a QA server before deploying to production. See the Stash upgrade guide.

バックアップとリカバリ

• We highly recommend that you establish a data recovery plan that is aligned with your company's policies. See Data recovery and backups for information about tools and backup strategies for Stash.

ログ

• Stash server logs can be found in <STASH_HOME>/log. Logs for the bundled Tomcat webserver can be found in <Stash installation directory>/log. See Stash debug logging.
• Stash displays recent audit events for each repository and project (only visible to Stash admins and system admins), and also creates full audit log files that can be found in the <Stash home directory >/audit/logs directory. Note that Stash has an upper limit to the number of log files it maintains, and deletes the oldest file when a new file is created – we recommend an automated backup of log files. See Audit logging in Stash.
