Node connector with docker compose

This example Dockerfile packages our example Node Fluvio project into a connector image.



FROM node:18

# Run as the `fluvio` user instead of root
ENV USER=fluvio
RUN useradd --create-home "$USER"
WORKDIR /home/fluvio 

# Copy your Node project
COPY --chown=$USER:$USER *.ts ./
COPY --chown=$USER:$USER *.json ./

# Install dependencies
RUN mkdir -p ~/.local/bin && \
   npm config set prefix '~/.local/' && \
   npm init -y && \
   npm install -D typescript ts-node @types/node && \
   npm install -S @fluvio/client

# Run your Node project
CMD npx ts-node example.ts

This docker-compose.yml used with docker compose CLI starts our previously built connector image as a local connector



version: "3"
   build: .
   network_mode: "host"
     - $HOME/.fluvio/config:/home/fluvio/.fluvio/config:ro
     - $HOME/.kube:/home/fluvio/.kube:ro

Run example

$ docker compose build
$ docker compose run example
