- Filter out user-specific env vars (HOME, USER, LOGNAME, SHELL, etc.)
from template default_env so they don't override envd's per-user
resolution. Fixes bash sourcing /root/.bashrc as wrenn-user.
- Keep WRENN_SANDBOX (legitimate runtime flag), only filter per-sandbox
IDs (WRENN_SANDBOX_ID, WRENN_TEMPLATE_ID).
- Add "127.0.0.1 sandbox" to /etc/hosts in wrenn-init.sh so sudo can
resolve the hostname. Fixes "unable to resolve host sandbox" error.
- Move capsule lifecycle buttons (Pause/Resume/Snapshot/Destroy) to the
same row as Stats/Files/Terminal tabs.
- Show vCPU/Memory for all template types with Required/Recommended
tooltips on the user templates page.
Implement three new recipe commands for the admin template builder:
- USER <name>: creates the user (adduser + passwordless sudo), switches
execution context so subsequent RUN/START commands run as that user
via su wrapping. Last USER becomes the template's default_user.
- COPY <src> <dst>: copies files from an uploaded build archive
(tar/tar.gz/zip) into the sandbox. Source paths validated against
traversal. Ownership set to the current USER.
- ENV persistence: accumulated env vars stored in templates.default_env
(JSONB) and injected via PostInit when sandboxes are created from the
template, mirroring Docker's image metadata approach.
Supporting changes:
- Pre-build creates wrenn-user as default (via USER command)
- WORKDIR now creates the directory if it doesn't exist (mkdir -p)
- Per-step progress updates (ProgressFunc callback) for live UI
- Multipart form support on POST /v1/admin/builds for archive upload
- Proto: default_user/default_env fields on Create/ResumeSandboxRequest
- Host agent: SetDefaults calls PostInitWithDefaults on envd
- Control plane: reads template defaults, passes on sandbox create/resume
- Frontend: file upload widget, recipe copy button, keyword colors for
USER/COPY, fixed Svelte whitespace stripping in step display
- Admin panel defaults to /admin/templates instead of /admin/hosts
- Migration adds default_user and default_env to templates and
template_builds tables
