RubyMine 2026.2: Selecting Per‑Developer Docker SDKs vs. Shared Docker Compose for Zero‑Downtime Migration

RubyMine 2026.2 Remote SDKs

RubyMine 2026.2 lets you configure a remote Ruby interpreter backed by Docker or Docker Compose. A Rails project can run inside a containerized environment while the IDE remains local.

Per‑Developer Docker SDK vs. Shared Docker Compose Stack

Developers can each run a lightweight Docker SDK or all share a single Docker Compose stack that includes database, cache, and other services. The IDE supports both, but the choice impacts debug‑gem compatibility, image rebuild frequency, and team consistency.

Debug‑Gem Compatibility

Debugging inside a container requires the same ruby‑debug‑ide and debase gem versions that RubyMine bundles. A mismatch between the container’s Ruby version and the IDE’s expected gems can silently break breakpoints.

Gemfile Lock Synchronization

With a remote SDK, bundler runs inside the image. Keeping the image’s gem set in sync with Gemfile.lock usually requires rebuilding the image rather than installing gems from the IDE.

Unresolved Decision Points

Which model—per‑developer Docker SDKs or a shared Docker Compose stack—provides the most reliable zero‑downtime migration and consistent debug‑gem compatibility across the team?

What strategy ensures that the container image’s gem set remains synchronized with the project’s Gemfile.lock during iterative development?

How can teams mitigate network latency or firewall issues that may cause breakpoints to miss when debugging through a remote Docker SDK?
