SandboxTemplatesAPI
Week of April 19 – April 26

​
New features

  • Update internet access on running sandboxes. The sandbox network endpoint now accepts allow_internet_access. Toggling it on a running sandbox blocks (or restores) all egress without recreating it. See internet access.
  • FUSE in sandboxes for non-root users. Templates can now mount FUSE filesystems from non-root accounts. user_allow_other is enabled by default and /dev/fuse is accessible without sudo. See building templates.
  • Manual template builds. You can now trigger a template build manually after creating it, decoupling build-time from create-time. See build templates.

​
Updates

  • Clearer template-not-found errors. When you create a sandbox or build from a base template, the API now distinguishes between a missing alias, an unbuilt tag, and access errors — and shows the name and tag you actually requested instead of an opaque internal ID. See template names and tags.
  • Finer-grained sandbox memory metrics. Sandbox metrics now report per-sample peak memory instead of a lifetime maximum, so memory spikes show up immediately. See sandbox metrics.

​
Fixes

  • Killing a sandbox during pause no longer errors. If a kill request lands while the sandbox is being paused, it now waits for the pause to complete and returns success once the sandbox is gone, instead of failing with a not-found error.
  • Restored sandboxes stay reachable after envd restarts. A transient envd crash inside the sandbox no longer leaves the service in a failed state across pause/resume — it now restarts indefinitely so the sandbox keeps responding. See auto-resume.
  • Bun-based templates no longer leak .env.local during install. Template installs using Bun now ignore .env.local so unintended environment variables don’t make it into the build.
  • Stability fix in the network pool. Resolved a rare race that could panic the orchestrator’s network pool during shutdown, reducing dropped sandboxes under load.
