Adds `--image-uri <uri>` to `langgraph deploy` so self-hosted LangSmith customers can build, push, and deploy in one command without needing to script the three steps manually. When `--image-uri` is provided the CLI: - Builds the image tagged to the provided URI (same Docker build path as the local build flow) - Pushes using whatever Docker credentials are already in the environment (e.g. WIF, `aws ecr get-login-password`) — no auth handling in the CLI - PATCHes the deployment with `source_revision_config.image_uri` (no `revision_source`, which the self-hosted control plane rejects for `external_docker` deployments) Also fixes two self-hosted-specific issues uncovered during testing: - `LANGSMITH_ENDPOINT` is now used as a fallback when `LANGGRAPH_HOST_URL` isn't set — the CLI strips the `/api/v1` path and appends `/api-host` to reach the control plane - The httpx client now builds full URLs via string concatenation rather than relying on httpx base_url merging, which silently dropped the `/api-host` path prefix when paths started with `/` - The "Check status at" URL after a deploy now correctly points to the self-hosted LangSmith UI instead of `smith.langchain.com` **How did you verify your code works?** Tested end-to-end against a self-hosted LangSmith instance using ECR as the registry. `langgraph deploy --image-uri <ecr-uri>` successfully built, pushed, and triggered a deployment revision. Confirmed the existing SaaS flow (`langgraph deploy` without `--image-uri`) is unaffected — the new flag is opt-in and the `LANGSMITH_ENDPOINT` fallback only activates when `LANGGRAPH_HOST_URL` is unset and `LANGSMITH_ENDPOINT` is present. --------- Co-authored-by: Hari Dhanushkodi <hari-dhanushkodi@users.noreply.github.com> Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> Co-authored-by: Hugo Durand <hugo.durand@langchain.dev>
