Use Fluvio in Docker

Docker Compose + Fluvio

You can run Fluvio Clusters in a Docker Compose setup, for a local proof of concept or development.

To run a Fluvio Cluster through Docker, you will need to run Fluvio components separately, we can use Docker Compose services to achieve this.

Services

• sc: Streaming Controller
• sc-setup: Post-Initialization Commands
• spu: Streaming Processing Unit

To learn more about Fluvio architecture, please refer to Fluvio Documentation.

Running

Copy the docker-compose.yaml and Dockerfile to a directory.

Or clone the Fluvio repo git clone https://github.com/infinyon/fluvio.git and cd into ./fluvio/examples/docker-compose

docker-compose.yaml:

version: "3"
services:
  sc:
    image: infinyon/fluvio:stable
    container_name: sc
    hostname: sc
    ports:
      - "9103:9003"
    environment:
      - RUST_LOG=info
    command: "./fluvio-run sc --local /fluvio/metadata"
    volumes:
      - ./fluvio-metadata:/fluvio/metadata
  sc-setup:
    build:
      context: .
      dockerfile: Dockerfile
    container_name: sc-setup
    environment:
      - RUST_LOG=info
    entrypoint: >
      /bin/sh -c "
      fluvio profile add docker sc:9003 docker;
      fluvio cluster spu register --id 5001 -p 0.0.0.0:9110 --private-server spu:9011;
      exit 0;
      "
    depends_on:
      - sc
  spu:
    image: infinyon/fluvio:stable
    container_name: spu
    hostname: spu
    volumes:
      - ./fluvio-data:/fluvio/data
    environment:
      - RUST_LOG=info
    ports:
      - "9110:9010"
      - "9111:9011"
    command: "./fluvio-run spu -i 5001 -p spu:9010 -v spu:9011 --sc-addr sc:9004 --log-base-dir /fluvio/data"
    depends_on:
      - sc

Dockerfile:

FROM ubuntu:20.04

RUN apt-get update
RUN apt-get install -y curl unzip
RUN curl -fsS https://hub.infinyon.cloud/install/install.sh?ctx=dc | bash

ENV PATH "$PATH:/root/.fluvio/bin"
ENV PATH "$PATH:/root/.fvm/bin"

Run docker compose up.

Optionally you can run on detached mode docker compose up -d so Fluvio runs in the background.

Then use the Fluvio CLI to connect to the cluster running in Docker, to do that you must set the Fluvio Profile to point to Docker's container SC:

If you dont have the Fluvio CLI installed on your local machine, run the following command curl -fsS https://hub.infinyon.cloud/install/install.sh | bash. Refer to Fluvio CLI Reference for more details.

fluvio profile add docker 127.0.0.1:9103 docker

Fluvio Streaming Controller (SC) usually runs on port 9003 but given that our SC is running in a Docker Container, internal port 9003 is mapped to 9103 in your system's network.

With the profile set, you are now able to perform Fluvio Client operations like listing topics:

fluvio topics list

Teardown

In order to shutdown the Fluvio Cluster running in Docker, you must issue the following compose command:

docker compose down

Remember to run this command in the same directory as the docker-compose.yml file.
