Docker

TigerBeetle can be run using Docker. However, it is not recommended.

TigerBeetle is distributed as a single, small, statically-linked binary. It should be easy to run directly on the target machine. Using Docker as an abstraction adds complexity while providing relatively little in this case.

Image​

The Docker image is available from the Github Container Registry:

https://github.com/tigerbeetle/tigerbeetle/pkgs/container/tigerbeetle

Format the Data File​

When using Docker, the data file must be mounted as a volume:

docker run --security-opt seccomp=unconfined \
     -v $(pwd)/data:/data ghcr.io/tigerbeetle/tigerbeetle \
    format --cluster=0 --replica=0 --replica-count=1 /data/0_0.tigerbeetle
info(io): creating "0_0.tigerbeetle"...
info(io): allocating 660.140625MiB...

Run the Server​

docker run -it --security-opt seccomp=unconfined \
    -p 3000:3000 -v $(pwd)/data:/data ghcr.io/tigerbeetle/tigerbeetle \
    start --addresses=0.0.0.0:3000 /data/0_0.tigerbeetle
info(io): opening "0_0.tigerbeetle"...
info(main): 0: cluster=0: listening on 0.0.0.0:3000

Run a Multi-Node Cluster Using Docker Compose​

Format the data file for each replica:

docker run --security-opt seccomp=unconfined -v $(pwd)/data:/data ghcr.io/tigerbeetle/tigerbeetle format --cluster=0 --replica=0 --replica-count=3 /data/0_0.tigerbeetle
docker run --security-opt seccomp=unconfined -v $(pwd)/data:/data ghcr.io/tigerbeetle/tigerbeetle format --cluster=0 --replica=1 --replica-count=3 /data/0_1.tigerbeetle
docker run --security-opt seccomp=unconfined -v $(pwd)/data:/data ghcr.io/tigerbeetle/tigerbeetle format --cluster=0 --replica=2 --replica-count=3 /data/0_2.tigerbeetle

Note that the data file stores which replica in the cluster the file belongs to.

Then, create a docker-compose.yml file:

version: "3.7"

##
# Note: this example might only work with linux + using `network_mode:host` because of 2 reasons:
#
# 1. When specifying an internal docker network, other containers are only available using dns based routing:
#    e.g. from tigerbeetle_0, the other replicas are available at `tigerbeetle_1:3002` and
#    `tigerbeetle_2:3003` respectively.
#
# 2. Tigerbeetle performs some validation of the ip address provided in the `--addresses` parameter
#    and won't let us specify a custom domain name.
#
# The workaround for now is to use `network_mode:host` in the containers instead of specifying our
# own internal docker network
##

services:
  tigerbeetle_0:
    image: ghcr.io/tigerbeetle/tigerbeetle
    command: "start --addresses=0.0.0.0:3001,0.0.0.0:3002,0.0.0.0:3003 /data/0_0.tigerbeetle"
    network_mode: host
    volumes:
      - ./data:/data
    security_opt:
      - "seccomp=unconfined"

  tigerbeetle_1:
    image: ghcr.io/tigerbeetle/tigerbeetle
    command: "start --addresses=0.0.0.0:3001,0.0.0.0:3002,0.0.0.0:3003 /data/0_1.tigerbeetle"
    network_mode: host
    volumes:
      - ./data:/data
    security_opt:
      - "seccomp=unconfined"

  tigerbeetle_2:
    image: ghcr.io/tigerbeetle/tigerbeetle
    command: "start --addresses=0.0.0.0:3001,0.0.0.0:3002,0.0.0.0:3003 /data/0_2.tigerbeetle"
    network_mode: host
    volumes:
      - ./data:/data
    security_opt:
      - "seccomp=unconfined"

And run it:

docker-compose up
docker-compose up
Starting tigerbeetle_0   ... done
Starting tigerbeetle_2   ... done
Recreating tigerbeetle_1 ... done
Attaching to tigerbeetle_0, tigerbeetle_2, tigerbeetle_1

... and so on ...

Troubleshooting​

error: PermissionDenied​

If you see this error at startup, it is likely because you are running Docker 25.0.0 or newer, which blocks io_uring by default. Set --security-opt seccomp=unconfined to fix it.

exited with code 137​

If you see this error without any logs from TigerBeetle, it is likely that the Linux OOMKiller is killing the process. If you are running Docker inside a virtual machine (such as is required on Docker or Podman for macOS), try increasing the virtual machine memory limit.

Alternatively, in a development environment, you can lower the size of the cache so TigerBeetle uses less memory. For example, set --cache-grid=256MiB when running tigerbeetle start.

Debugging panics​

If TigerBeetle panics and you can reproduce the panic, you can get a better stack trace by switching to a debug image (by using the :debug Docker image tag).

docker run -p 3000:3000 -v $(pwd)/data:/data ghcr.io/tigerbeetle/tigerbeetle:debug \
    start --addresses=0.0.0.0:3000 /data/0_0.tigerbeetle

On MacOS​

error: SystemResources​

If you get error: SystemResources when running TigerBeetle in Docker on macOS, you will need to do one of the following:

  1. Run docker run with --cap-add IPC_LOCK
  2. Run docker run with --ulimit memlock=-1:-1
  3. Or modify the defaults in $HOME/.docker/daemon.json and restart the Docker for Mac application:
{
  ... other settings ...
  "default-ulimits": {
    "memlock": {
      "Hard": -1,
      "Name": "memlock",
      "Soft": -1
    }
  },
  ... other settings ...
}

If you are running TigerBeetle with Docker Compose, you will need to add the IPC_LOCK capability like this:

... rest of docker-compose.yml ...

services:
  tigerbeetle_0:
    image: ghcr.io/tigerbeetle/tigerbeetle
    command: "start --addresses=0.0.0.0:3001,0.0.0.0:3002,0.0.0.0:3003 /data/0_0.tigerbeetle"
    network_mode: host
    cap_add:       # HERE
      - IPC_LOCK   # HERE
    volumes:
      - ./data:/data

... rest of docker-compose.yml ...
