Dockerでアプリケーションを一貫して実行

3月 9, 2026
IDEでのDockerデプロイで、開発者が開発ワークスペースから直接コンテナ化されたアプリケーションを構築、実行、デバッグすることが可能

Docker deployment in Integrated Development Environments (IDEs) refers to the capability to build, configure, and run applications inside Docker containers directly from the development workspace. Through built-in Docker integration, developers can package an application together with its required libraries, runtime, and operating system dependencies into a container image, then deploy and execute that container on local or remote Docker hosts. This approach allows developers to test and run applications in consistent, reproducible environments that mirror production systems, reducing configuration differences between development, testing, and deployment stages while simplifying container management tasks such as building images, running containers, and updating services.

Several IDEs offer support for Docker deployment including:

  • Rider by JetBrains lets you build, run, and debug applications in Docker containers directly from the IDE with integrated tooling.
  • RemObjects Elements by RemObjects Software allows you to leverage host IDE Docker tools to containerize, build, and run compiled applications within consistent environments.
  • Microsoft Visual Studio Professional allows you to build images, deploy, run, and debug applications in Docker containers from integrated container tools.

IDE内でのコード品質を向上

最新のIDEには包括的なテストツールが含まれており、チームが早期に変更を検証し、信頼性が高く保守可能なアプリケーションを維持可能

Integrated Development Environments (IDEs) are comprehensive software applications that provide developers with a unified workspace for writing, editing, compiling, debugging, and managing source code across one or more programming languages. In addition to core coding features such as syntax highlighting, intelligent code completion, and version control integration, most modern IDEs include built-in testing functionality that supports popular testing frameworks for unit, integration, and sometimes end-to-end testing. These environments typically allow developers to create and organize test projects, run tests directly from the editor, view structured test results, and quickly navigate from failed tests to the relevant source code. Many IDEs also offer advanced capabilities such as code coverage analysis, test discovery, continuous test execution, and debugging tools that work seamlessly within test cases, helping development teams maintain code quality and detect issues early in the development lifecycle.

Common testing features include:

  • Code Coverage measures which parts of the codebase are executed during tests, highlighting untested areas to improve reliability and maintainability.
  • Issue Tracker Integration connects test results with issue tracking systems, enabling teams to link failures to defects and manage resolution processes efficiently.
  • Test Explorer provides a centralized interface within the IDE to discover, organize, run, and monitor automated tests and review detailed results.
  • Unit Testing supports the creation and execution of isolated tests for individual components or units of source code, validating functionality early and reducing regression risks.

AIエージェントを直接IDE内で閲覧・インストール

2月 17, 2026
JetBrains AI Assistantには新しいACPエージェントレジストリが含まれており、設定ステップを削減し、エージェントのコーディング実験を容易に

JetBrains AI Assistant - AI Pro is a plugin for JetBrains IDEs that uses large language models to enhance your coding experience. It can answer your questions about code, suggest completions and refactorings, and even help you write documentation and commit messages. It analyzes the context of your project to provide the most relevant suggestions, and you can chat with it directly within the IDE. JetBrains AI Assistant is a powerful tool for programmers looking to boost their productivity.

Agent Client Protocol (ACP) Agent Registry is now available in JetBrains IDEs, making it simple to browse a curated list of ACP-compatible coding agents and install them with a single click. There is no manual configuration required, so developers can quickly try different agents for different tasks and move between them as needed, all within the same chat interface. The registry also removes barriers to entry making experimentation and adoption more accessible across teams.

JetBrains AI Assistant is licensed per user as a commercial annual subscription. To use it, you must have a compatible JetBrains IDE. We can supply new subscriptions, subscription renewals, lapsed subscription renewals, and additional developer licenses. See our JetBrains AI Assistant licensing page for full details.

RubyMine 2025.3は、ネストされたクラス名やモジュール名のファジィ検索機能を追加し、複雑な名前空間での作業を容易に

RubyMine by JetBrains is a Integrated Development Environment (IDE) specifically designed for Ruby and Ruby on Rails development. It offers a comprehensive suite of features to improve your coding efficiency, including smart code completion, syntax highlighting, code refactoring tools, built-in debugging and testing frameworks, and integration with popular libraries and databases. Whether you're a seasoned Rails developer or just starting out, RubyMine's intuitive interface and robust features can help you write cleaner, more maintainable code and accelerate your development.

The RubyMine 2025.3 release enhances code completion for qualified constants by introducing fuzzy search across namespaces. This lets developers type partial names, such as "FoBa", and receive accurate suggestions like "Foo::Bar", even when dealing with deeply nested structures. The update helps speed up navigation and code writing in projects with large or hierarchically organized modules, making it easier to locate and use the right constants with minimal input.

To see a full list of what's new in version 2025.3, see our release notes.

RubyMine is licensed per user, and is available as a commercial annual subscription license. We can supply new subscriptions, subscription renewals, lapsed renewals, and additional user licenses. See our RubyMine licensing page for full details.
