Qdrant

Since v0.29.0

Introduction

The Testcontainers module for Qdrant.

Adding this module to your project dependencies

Please run the following command to add the Qdrant module to your Go dependencies:

go get github.com/testcontainers/testcontainers-go/modules/qdrant

Usage example

Creating a Qdrant container

ctx := context.Background()

qdrantContainer, err := qdrant.Run(ctx, "qdrant/qdrant:v1.7.4")
defer func() {
    if err := testcontainers.TerminateContainer(qdrantContainer); err != nil {
        log.Printf("failed to terminate container: %s", err)
    }
}()
if err != nil {
    log.Printf("failed to start container: %s", err)
    return
}

Module Reference

Run function

Info

The RunContainer(ctx, opts...) function is deprecated and will be removed in the next major release of Testcontainers for Go.

The Qdrant module exposes one entrypoint function to create the Qdrant container, and this function receives three parameters:

func Run(ctx context.Context, img string, opts ...testcontainers.ContainerCustomizer) (*QdrantContainer, error)
  • context.Context, the Go context.
  • string, the Docker image to use.
  • testcontainers.ContainerCustomizer, a variadic argument for passing options.

Image

Use the second argument in the Run function to set a valid Docker image. In example: Run(context.Background(), "qdrant/qdrant:v1.7.4").

Container Options

When starting the Qdrant container, you can pass options in a variadic way to configure it.

The following options are exposed by the testcontainers package.

Basic Options

Lifecycle Options

Files & Mounts Options

Build Options

Logging Options

Image Options

Networking Options

Advanced Options

Experimental Options

Container Methods

The Qdrant container exposes the following methods:

REST Endpoint

This method returns the REST endpoint of the Qdrant container, using the default 6333 port.

Get REST endpoint

restEndpoint, err := ctr.RESTEndpoint(ctx)

Web UI Endpoint

This method returns the Web UI endpoint of the Qdrant container (/dashboard), using the default 6333 port.

Get Web UI endpoint

webUI, err := ctr.WebUI(ctx)

gRPC Endpoint

This method returns the gRPC endpoint of the Qdrant container, using the default 6334 port.

Get gRPC endpoint

grpcEndpoint, err := ctr.GRPCEndpoint(ctx)

Full Example

Here you can find a full example on how to use the qdrant-go module to perform operations with Qdrant, as seen in the examples provided by the module itself:

Full Example

qdrantContainer, err := qdrant.Run(context.Background(), "qdrant/qdrant:v1.7.4")
defer func() {
    if err := testcontainers.TerminateContainer(qdrantContainer); err != nil {
        log.Printf("failed to terminate container: %s", err)
    }
}()
if err != nil {
    log.Printf("failed to start container: %s", err)
    return
}

grpcEndpoint, err := qdrantContainer.GRPCEndpoint(context.Background())
if err != nil {
    log.Printf("failed to get gRPC endpoint: %s", err)
    return
}

// Set up a connection to the server.
conn, err := grpc.NewClient(grpcEndpoint, grpc.WithTransportCredentials(insecure.NewCredentials()))
if err != nil {
    log.Printf("did not connect: %v", err)
    return
}
defer conn.Close()

    return
}

// 2. Contact the server and print out its response.

    CollectionName: collectionName,
    FieldName:      fieldIndex2Name,
    FieldType:      &fieldIndex2Type,
