I'm new to docker and I'm trying to run h2o in docker and then use python to connect to it. I have folder with: model-generator folder in which I have the python script and Dockerfile to build an image h2o-start folder in which I have h2o.jar file and Dockerfile to start that jar docker-compose.yml file with:
version: "3"
services:
h2o-start:
image: milanpanic2/h2o-start
build:
context: ./h2o-start
restart: always
model-generator:
image: milanpanic2/model-generator
build:
context: ./model-generator
restart: always
My python script contains:
import h2o
h2o.connect(ip='172.19.0.3', port='54321')
When I run docker-compose up it gives me an error that python can't connect, because there isn't anything on 172.19.0.3
Dockerfile for python
FROM python:2.7-slim
WORKDIR /app
ADD . /app
RUN pip install > --trusted-host pypi.python.org -r requirements.txt
EXPOSE 80
ENV NAME World
CMD ["python", "passhash.py"]
Dockerfile for h2o
FROM openjdk:8
ADD h2o.jar h2o.jar
EXPOSE 54321 EXPOSE 54322
ENTRYPOINT ["java", "-jar", "h2o.jar"]
Try to start container exposing port 54321: add to your h2o-start:
in docker-compose file:
ports:
- "54321:54321"
- "54322:54322"
