## Summary
`langgraph deploy` now pins images by digest when handing the URI to the
LangGraph host backend. After `docker push`, the CLI reads the manifest
digest from the local Docker daemon's `RepoDigests` and sends
`registry/repo@sha256:<hex>` to the host backend instead of the
tag-based reference. Mutable tags cause downstream inconsistency — the
same revision can refer to different images over time.
The image is still pushed under the user-supplied `--tag` (default
`:latest`) so it stays discoverable by tag in the registry — only the
URI persisted with the revision changes.
## Behavior on failure
If the digest can't be resolved (empty `RepoDigests`, or no entry
matching the just-pushed repo), the CLI warns and falls back to the
tag-based reference. Deploys never fail on a digest-resolution issue.
## Test plan
- [x] `make test` passes (new `TestResolvePushedImageDigest` cases
included)
- [x] `--verbose` deploy shows the `docker image inspect` call resolving
the digest
- [x] Deploy with a clean Docker daemon (no matching `RepoDigests`)
emits the fallback warning and still completes successfully

Today, pre-release versions aren't supported for the `api_version`
config parameter in langgraph.json. This adds support for them to enable
latest and rc images going forward.
# Description
Supports deploying to langsmith from langgraph studio
Adds the following to the langgraph deploy command:
- json event output
- non-interactive mode
## Summary
Adds native uv workspace/lockfile support to the LangGraph CLI's Docker
build pipeline. Instead of listing dependencies manually, users can
point at their existing `uv.lock` and the CLI will:
1. Discover workspace packages and their dependency graph
2. Export locked requirements via `uv export --package <name> --frozen`
3. Copy only the necessary workspace closure into the container
4. Install packages in dependency order with `--no-deps` for
reproducibility
5. Rewrite all import paths (graphs, auth, encryption, etc.) to
container paths
### New config field: `source`
Rather than using `pip` or `uv pip`, we add a new `uv_lock` installer.
The previous installers should still remain unchanged.
To avoid ambiguity, we discriminate by "source" field and **do not
permit** other arbitrary "dependencies". In this mode, we will treat the
provided root (defaults to the current directory) as the source of
truth.
This also would natively support uv workspaces, so you can specify the
target package within a larger workspace.
**Simple single-package project:**
```json
{
"python_version": "3.11",
"graphs": {
"agent": "./agent.py:graph"
},
"source": {
"kind": "uv"
}
}
```
**Multi-package workspace with explicit package:**
```json
{
"python_version": "3.11",
"graphs": {
"agent": "../../apps/agent/src/agent/graph.py:graph"
},
"source": {
"kind": "uv",
"root": "../..",
"package": "agent"
}
}
```
**Traditional pip deployment (unchanged):**
```json
{
"python_version": "3.11",
"dependencies": ["langgraph", "my-package"],
"graphs": {
"agent": "./agent.py:graph"
}
}
```
Config validation enforces mutual exclusivity. you must use either
`dependencies` or `source`, not both.

Allow users to deploy to langsmith deployments from the langgraph-cli.
This PR makes the following changes:
1. Add a simple host backend client with httpx
2. Adjust `progress.py` to show elapsed time for commands, and also use
threading.Event to stop the spinner
3. Adjust `_build` to allow arbitrary command so we can pass `docker
buildx build` and default to `docker build`
4. Add new `deploy` command, this re-uses a lot of the `langgraph build`
functionality, and then uses the new host-backend client to push the
built image to langsmith deployments.

**Description:**
This PR adds the Python SDK types necessary for langgraph platform users
to inject their own custom encryption-at-rest functions. See [docs
PR](https://github.com/langchain-ai/docs/pull/1715) for more details.
note: this PR adds a starlette dev dependency so that custom encryption
can access BaseUser information.
**Issue:**
required for LSD-172
**Dependencies:**
- [depended upon by associated langgraph-api
changes](https://github.com/langchain-ai/langgraph-api/pull/1773)(this
PR must merge before that one)
- [docs PR](https://github.com/langchain-ai/docs/pull/1715)
**TODO:**
- [x] move docs to docs repo
- [x] bump package versions before merge

**Description:** Adds the syntax directive to generated dockerfile for
langgraph builds if we have additional contexts
**Issue:** fixes issue with python monorepo builds failing
**Dependencies:** N/A
**Description**
As part of this PR #6156, local deps are no longer installed in editable
mode. This change reverts that behaviour and ensures local packages are
installed in editable mode.
**Issue:** fixes#6288
some of these changes were obvious, and some were less obvious. In a few
spots, it felt like a judgement call if we should be saying LangSmith
Deployment of LangGraph Server. But hopefully either works.
This adds a configuration option in `HttpConfig` that allows LangGraph
Platform users to apply custom authentication hooks before (other)
custom middleware. Currently, the order is fixed (custom middleware is
always evaluated before custom auth).
(Apologies for the noise in
[de187a9](https://github.com/langchain-ai/langgraph/pull/6179/commits/de187a989e807c5687c22db1fc065d24030fa6b7),
apparently from the forced application of new linter rules.)
### Description
Added unit tests for util.py.
Authored by @oumizx. Had to copy #6113 into this separate PR because
langgraph/libs/cli was having issues with secrets.
Description:
Corrects _parse_version to support Docker versions with SemVer build
metadata (e.g., 28.1.1+1), resolving #5965. Adds comprehensive unit
tests for version parsing, including normal, v-prefixed, prerelease,
build metadata, combined prerelease/build metadata, and edge cases with
missing components.
Issue:
Closes#5965
Dependencies:
None

We previously errored when a user had prerelease dependencies, this PR
passes the `--prereleases=allow` flag to our `uv pip install` call.
This PR also adds a test to verify that said deployments will build and
run as expected.
This PR introduces the `--build-command` and `--install-command`
arguments to `langgraph build`.
`--install-command` is a custom install command. If passed, it will be
run from wherever the `langgraph build` call was made, i.e. NOT where
the langgraph.json file lives (except if these are the same place). This
will override the detected install command that we previously used.
`--build-command` is a custom build command. This will run from wherever
the langgraph.json file lives, and will be done after the install has
been run.
You don't need to provide both. Just providing one will make the install
(detected or supplied) run in the directory from where `langgraph build
was called` and then have the build command (if one exists) run in the
directory where langgraph.json exists.
I think we should probably allow configuring the directories from which
these commands get run, but I don't think this needs to be part of the
MVP.

* Generate one `--build-context` for each dependency in the `docker build` command.
* Try and fix test
---------
Co-authored-by: Nuno Campos <nuno@langchain.dev>
* Migrate to `uv`
* Format `pyproject.toml` files properly
* Remove upper bounds on dependencies, and bounds on dev dependencies
(we should be using latest)
* Move to hatch for packaing
In the future we should:
* Set up dependabot / automate lockfile updates and tests
* Add tests for min compatible versions (I'll do this right after merge)
* Use dynamic versioning
* Bump `pydantic` to v2.11.4 in the lockfile, we have some tests failing
