Fluvio - Java connector with docker compose

Java connector with docker compose

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

Dockerfile

FROM openjdk:11

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

# Installing Fluvio CLI for creating topics in example
RUN curl -fsS https://hub.infinyon.cloud/install/install.sh | bash
ENV PATH=/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/fluvio/.fluvio/bin

# Copy your Java project and run it
COPY --chown=$USER:$USER fluvio-java .
CMD ./gradlew run

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

docker-compose.yml

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

Run example

$ docker compose build

$ docker compose run example
