LangSmith upgrades may include database migrations and other changes that are not backward-compatible. If you need to roll back to a previous version, contact [support](mailto:support@langchain.dev) for guidance. If you don't have the repo added, run the following command to add it: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} helm repo add langchain https://langchain-ai.github.io/helm/ ``` Update your local helm repo ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} helm repo update ``` Update your helm chart config file with any updates that are needed in the new version. These will be detailed in the release notes for the new version. Run the following command to upgrade the chart (replace `version` with the version you want to upgrade to): If you are using a namespace other than the default namespace, you will need to specify the namespace in the `helm` and `kubectl` commands by using the `-n Find the latest version of the chart. You can find this in the [LangSmith Helm Chart GitHub repository](https://github.com/langchain-ai/helm/releases) or by running the following command: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} helm search repo langchain/langsmith --versions ``` You should see output similar to this: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} langchain/langsmith 0.10.14 0.10.32 Helm chart to deploy the langsmith application ... langchain/langsmith 0.10.13 0.10.32 Helm chart to deploy the langsmith application ... langchain/langsmith 0.10.12 0.10.32 Helm chart to deploy the langsmith application ... langchain/langsmith 0.10.11 0.10.29 Helm chart to deploy the langsmith application ... langchain/langsmith 0.10.10 0.10.29 Helm chart to deploy the langsmith application ... langchain/langsmith 0.10.9 0.10.29 Helm chart to deploy the langsmith application ... ``` Choose the version you want to upgrade to (generally the latest version is recommended) and note the version number: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} helm upgrade langchain/langsmith --version --values --wait --debug ``` Verify that the upgrade was successful: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} helm status ``` All pods should be in the `Running` state. Verify that ClickHouse is running and that both `migrations` jobs have completed. ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} kubectl get pods NAME READY STATUS RESTARTS AGE langsmith-backend-95b6d54f5-gz48b 1/1 Running 0 15h langsmith-pg-migrations-d2z6k 0/1 Completed 0 5h48m langsmith-ch-migrations-gasvk 0/1 Completed 0 5h48m langsmith-clickhouse-0 1/1 Running 0 26h langsmith-frontend-84687d9d45-6cg4r 1/1 Running 0 15h langsmith-hub-backend-66ffb75fb4-qg6kl 1/1 Running 0 15h langsmith-playground-85b444d8f7-pl589 1/1 Running 0 15h langsmith-queue-d58cb64f7-87d68 1/1 Running 0 15h ``` ## Validate your deployment 1. Run `kubectl get services` Output will be similar to: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 172.20.0.1 443/TCP 27d langsmith-backend ClusterIP 172.20.22.34 1984/TCP 21d langsmith-clickhouse ClusterIP 172.20.117.62 8123/TCP,9000/TCP 21d langsmith-frontend LoadBalancer 172.20.218.30 80:30093/TCP,443:31130/TCP 21d langsmith-platform-backend ClusterIP 172.20.232.183 1986/TCP 21d langsmith-playground ClusterIP 172.20.167.132 3001/TCP 21d langsmith-postgres ClusterIP 172.20.59.63 5432/TCP 21d langsmith-redis ClusterIP 172.20.229.98 6379/TCP 20d ``` 2. Curl the external ip of the `langsmith-frontend` service: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} curl /api/info {"version":"0.5.7","license_expiration_time":"2033-05-20T20:08:06","batch_ingest_config":{"scale_up_qsize_trigger":1000,"scale_up_nthreads_limit":16,"scale_down_nempty_trigger":4,"size_limit":100,"size_limit_bytes":20971520}} ``` Check that the version matches the version you upgraded to. 3. Visit the external IP for the `langsmith-frontend` service on your browser. The LangSmith UI should be visible and operational. LangSmith UI ***
