Docker image quick reference

Launch a primary instance

docker run --name some-sqld -p 8080:8080 -ti \
    -e SQLD_NODE=primary \
    ghcr.io/tursodatabase/libsql-server:latest

Launch a replica instance

docker run --name some-sqld-replica -p 8081:8080 -ti
    -e SQLD_NODE=replica \
    -e SQLD_PRIMARY_URL=https://<host>:<port> \
    ghcr.io/tursodatabase/libsql-server:lastest

Running on Apple Silicon

docker run --name some-sqld  -p 8080:8080 -ti \
    -e SQLD_NODE=primary \
    --platform linux/amd64 \
    ghcr.io/tursodatabase/libsql-server:latest

Note: the latest images for arm64 are available under the tag ghcr.io/tursodatabase/libsql-server:latest-arm, however for tagged versions, and stable releases please use the x86_64 versions via Rosetta.

How to extend this image

Data Persistance

Database files are stored in the /var/lib/sqld in the image. To persist the database across runs, mount this location to either a docker volume or a bind mount on your local disk.

docker run --name some-sqld -ti \
    -v $(pwd)/sqld-data:/var/lib/sqld \ # you can mount local path
    -e SQLD_NODE=primary \
    ghcr.io/tursodatabase/libsql-server:latest

docker run --name some-sqld -ti \
    -v sqld-data:/var/lib/sqld \ # or create named volume
    -e SQLD_NODE=primary \
    ghcr.io/tursodatabase/libsql-server:latest

docker run --name some-sqld -ti \
    -v sqld-data:/data/sqld \ # to mount data in different directory set SQLD_DB_PATH env var
    -e SQLD_NODE=primary \
    -e SQLD_DB_PATH=/data/sqld \
    ghcr.io/tursodatabase/libsql-server:latest

Authentication

SQLD_HTTP_AUTH

Specifies legacy HTTP basic authentication. The argument must be in format basic:$PARAM, where $PARAM is base64-encoded string $USERNAME:$PASSWORD.

SQLD_AUTH_JWT_KEY_FILE

Path to a file with a JWT decoding key used to authenticate clients in the Hrana and HTTP APIs. The key is either a PKCS#8-encoded Ed25519 public key in PEM, or just plain bytes of the Ed25519 public key in URL-safe base64.

You can also pass the key directly in the env variable SQLD_AUTH_JWT_KEY.

Environment variables

SQLD_NODE

default: primary

The SQLD_NODE environment variable configures the type of the launched instance. Possible values are: primary (default), replica, and standalone. Please note that replica instances also need the SQLD_PRIMARY_URL environment variable to be defined.

SQLD_PRIMARY_URL

The SQLD_PRIMARY_URL environment variable configures the gRPC URL of the primary instance for replica instances.

See: SQLD_NODE environment variable

SQLD_DB_PATH

default: iku.db

The location of the db file inside the container. Specifying only a filename will place the file in the default directory inside the container at /var/lib/sqld.

SQLD_HTTP_LISTEN_ADDR

default: 0.0.0.0:8080

Defines the HTTP listen address that sqld listens on and clients will connect to. Recommended to leave this on the default port and remap ports at the container networking level.

SQLD_GRPC_LISTEN_ADDR

default: 0.0.0.0:5001

Defines the GRPC listen address and port for sqld. Primarily used for inter-node communication. Recommended to leave this on default.

Docker Compose

Simple docker compose for local development:

version: "3"
services:
  db:
    image: ghcr.io/tursodatabase/libsql-server:latest
    platform: linux/amd64
    ports:
      - "8080:8080"
      - "5001:5001"
    # environment:
    #   - SQLD_NODE=primary
    volumes:
      - ./data/libsql:/var/lib/sqld
