By default, LangSmith will pull images from our public Docker registry. However, if you are running LangSmith in an environment that does not have internet access, or if you would like to use a private Docker registry, you can mirror the images to your own registry and then configure your LangSmith installation to use those images.

​
Requirements

  • Authenticated access to a Docker registry that your Kubernetes cluster/machine has access to.
  • Docker installed on your local machine or a machine that has access to the Docker registry.
  • A Kubernetes cluster or a machine where you can run LangSmith.

​
Mirroring the images

For your convenience, we have provided a script that will mirror the images for you. You can find the script in the LangSmith Helm Chart repository To use the script, you will need to run the script with the following command specifying your registry and platform: 
bash mirror_images.sh <your-registry> [<platform>]
Where <your-registry> is the URL of your Docker registry (e.g. myregistry.com) and <platform> is the platform you are using (e.g. linux/amd64, linux/arm64, etc.). If you do not specify a platform, it will default to linux/amd64. For example, if your registry is myregistry.com, your platform is linux/arm64, and you want to use the latest version of the images, you would run: 
bash mirror_langsmith_images.sh --registry myregistry --platform linux/arm64 --version 0.10.66
Note that this script will assume that you have Docker installed and that you are authenticated to your registry. It will also push the images to the specified registry with the same repository/tag as the original images. Alternatively, you can pull, mirror, and push the images manually. The images that you will need to mirror are found in the values.yaml file of the LangSmith Helm Chart. These can be found here: LangSmith Helm Chart values.yaml Here is an example of how to mirror the images using Docker: 
# Pull the images from the public registry
docker pull langchain/langsmith-backend:latest
docker tag langchain/langsmith-backend:latest <your-registry>/langsmith-backend:latest
docker push <your-registry>/langsmith-backend:latest
You will need to repeat this for each image that you want to mirror.

​
Configuration

Once the images are mirrored, you will need to configure your LangSmith installation to use the mirrored images. You can do this by modifying the values.yaml file for your LangSmith Helm Chart installation or the .env file for your Docker installation. Replace tag with the version you want to use, e.g. 0.10.66 for the latest version at the time of writing.

  imagePullSecrets: [] # Add your image pull secrets here if needed
  registry: "" # Set this to your registry URL if you mirrored all images to the same registry using our script. Then you can remove the repository prefix from the images below.

Additional images for Agent Builder and Insights

If you are using Agent Builder or Insights, the LangGraph operator dynamically creates Redis and PostgreSQL (pgvector) pods for each deployment. These pods use images defined in operator templates that require separate configuration. You must mirror these additional images:
  • docker.io/redis:7
  • docker.io/pgvector/pgvector:pg15
Then override the operator templates in your values.yaml to use your mirrored images: 
operator:
  templates:
    redis: |
      apiVersion: apps/v1
      kind: Deployment
      metadata:
        name: ${service_name}
        namespace: ${namespace}
      spec:
        replicas: 1
        selector:
          matchLabels:
            app: ${service_name}
        template:
          metadata:
            labels:
              app: ${service_name}
          spec:
            enableServiceLinks: false
            containers:
            - name: redis
              image: (your-registry)/redis:7
              ports:
              - containerPort: 6379
                name: redis
              livenessProbe:
                exec:
                  command:
                  - redis-cli
                  - ping
                initialDelaySeconds: 30
                periodSeconds: 10
              readinessProbe:
                tcpSocket:
                  port: 6379
                initialDelaySeconds: 10
                periodSeconds: 5
    db: |
      apiVersion: apps/v1
      kind: StatefulSet
      metadata:
        name: ${service_name}
      spec:
        serviceName: ${service_name}
        selector:
          matchLabels:
            app: ${service_name}
        persistentVolumeClaimRetentionPolicy:
          whenDeleted: Delete
          whenScaled: Retain
        template:
          metadata:
            labels:
              app: ${service_name}
          spec:
            containers:
            - name: postgres
              image: (your-registry)/pgvector/pgvector:pg15
              ports:
              - containerPort: 5432
              command: ["docker-entrypoint.sh"]
              args:
                - postgres
                - -c
                - max_connections=${max_connections}
              env:
              - name: PGDATA
                value: /var/lib/postgresql/data/pgdata
              volumeMounts:
              - name: postgres-data
                mountPath: /var/lib/postgresql/data
            enableServiceLinks: false
        volumeClaimTemplates:
        - metadata:
            name: postgres-data
          spec:
            accessModes: ["ReadWriteOnce"]
            resources:
              requests:
                storage: "${storage_gi}Gi"
Replace (your-registry) with your registry URL. The template variables (${service_name}, ${namespace}, ${max_connections}, ${storage_gi}) are replaced by the operator at runtime and must be kept as-is. Once configured, you will need to update your LangSmith installation. You can follow our upgrade guide here: Upgrading LangSmith. If your upgrade is successful, your LangSmith instance should now be using the mirrored images from your Docker registry.
