Then define `sync` steps and optional `run` triggers; during initial sync, untriggered `run` steps execute and triggered ones execute only when synced files match. Examples: ``` live_update=[ initial_sync(), sync('./src', '/app/src'), run('npm install', trigger=['./src/package.json']), ] ``` - why_it_matters: Use a pre-built image in a Tiltfile and sync local files into its container on start or restart. - sources: , , - gotchas: "Version: v0.37.3"; "initial_sync(): Must be first if provided. Takes no arguments; uploads files from `sync` paths when Tilt first observes a running container and whenever it restarts."; "sync(local_path, remote_path) (required): Local file or directory path and destination path in the container."; "run(cmd, trigger) (required): `cmd` runs in the container. Optional `trigger` is a filepath or list of filepaths; the command runs if synced files match. Without a trigger, it runs after initial sync completes."; "live_update (required): List of live update steps supplied when building or deploying an image; `initial_sync` precedes `sync`, which precedes `run`."; "Prerequisite: The image or deploy must be sufficient to start a running container without relying on synced files or `run` commands."; "Prerequisite: `sync` paths must be within the watched build context (or custom build dependencies)."; "`initial_sync()` must be first in the list."; "No compression; tested with gzip, but CPU overhead exceeded network savings for typical workloads (~20k files, ~90MB in under 20s to remote EKS)."; "No changes to existing `live_update` behavior."; "Docs conflict: The release note describes `initial_sync(ignore=..., dockerignore=...)`, but the current official reference says `initial_sync()` takes no arguments and describes exclusions through the image or custom deploy's file-watching controls. Do not use the release-note parameters based on this page. The official reference's current content may be newer than v0.37.3." ### tilt alpha tree-view displays dependency resources (2026-03-04) - slug: tilt-alpha-tree-view-displays-dependency-resources-9d7ed8818e36 - score: 0.97 How to use it: When you need to find resources blocking readiness, run `tilt alpha tree-view --blockers` to show blocked resources and their root blockers. The tree is organized by dependencies from the root Tiltfile; use `--dedupe` to show repeated subtrees only once. Examples: ``` tilt alpha tree-view --blockers ``` ``` tilt alpha tree-view --dedupe ``` - why_it_matters: Inspect a Tilt environment's dependency tree to find resources blocking readiness. - sources: , , - gotchas: "Version: v0.37.0"; "Availability: alpha"; "--blockers: Show only blocked resources and their root blockers."; "--dedupe: Deduplicate resources with multiple parents; show subtrees only once with annotations."; "The tree starts from the root Tiltfile." ### Tilt update_settings adds k8s_server_side_apply (2026-03-04) - slug: tilt-update-settings-adds-k8s-server-side-apply-c8fcf2db6855 - score: 0.96 How to use it: To control server-side apply for Kubernetes updates, set `k8s_server_side_apply` in the Tiltfile’s `update_settings` call to `"true"`, `"false"`, or `"auto"`. Examples: ``` update_settings(k8s_server_side_apply="true") ``` - why_it_matters: Configure whether Tilt uses Kubernetes server-side apply for resources in an environment. - sources: , , - gotchas: "Version: v0.37.0"; "k8s_server_side_apply: String controlling whether Kubernetes applies use server-side apply. Accepted values are `true`, `false`, and `auto`; default is `auto`."; "The option accepts only the stated values: `\"true\"`, `\"false\"`, or `\"auto\"`." ### tilt logs adds time, tail, and JSON output flags (2026-01-20) - slug: tilt-logs-adds-time-tail-and-json-output-flags-e950e36a23d5 - score: 0.97 How to use it: When debugging an application running through Tilt, use `tilt logs` to inspect its logs; add `--since=` for recent logs, `--tail=` to limit lines, or `--json` for JSON Lines output. Examples: ``` tilt logs --since=5m ``` ``` tilt logs --tail=100 ``` ``` tilt logs --json ``` - why_it_matters: Inspect Tilt logs while debugging an application running through Tilt. - sources: , - gotchas: "Version: v0.36.1"; "--since : Show logs only from the specified duration ago, such as `5m`, `1h`, or `30s`."; "--tail : Number of lines to show from the end; `-1` means all lines and is the default."; "--json: Output logs in JSON Lines format."; "Prerequisite: A Tilt instance must be running; `tilt logs` connects to localhost:10350 by default."
