1 month ago To resolve the Docker compose build failure related to fetch failing with ECONNREFUSED on ::1:8000, ensure that the service trying to connect to ::1:8000 (the IPv6 loopback address) is correctly configured to connect to the appropriate service within the Docker network.
Here are the steps to troubleshoot and resolve the issue:
-
Check Service Dependencies: Ensure that the service trying to connect to
::1:8000is correctly configured to wait for theserverservice to be up and running. Use thedepends_ondirective, but also consider implementing a health check or a retry mechanism. You can use thewait-for-it.shscript included in yourserverDockerfile to wait for theserverservice to be ready before starting dependent services. -
Update Connection URL: Ensure that any configuration files or environment variables specify the correct service name and port within the Docker network. Instead of
http://localhost:8000orhttp://::1:8000, usehttp://server:8000. -
Network Configuration: Ensure that all services are on the same Docker network.
Here is an example of how you might update an environment variable in your .env file or configuration to use the correct service name:
# .env file for the client or any other service trying to connect to the server
API_URL=http://server:8000If you are using a configuration file, update the URL accordingly:
{
"apiUrl": "http://server:8000"
}Additionally, ensure that your server service is properly set up to expose port 8000 and is using the wait-for-it.sh script to handle dependencies. Here is an example of how your server/Dockerfile might look:
# Use an official Python runtime as a parent image
FROM python:3.11-slim
# Set the working directory in the container
WORKDIR /app
# Install system dependencies
RUN apt-get update && apt-get install -y --no-install-recommends \
build-essential \
curl \
make \
&& apt-get clean \
&& rm -rf /var/lib/apt/lists/*
# Install Poetry
RUN curl -sSL https://install.python-poetry.org | python3 -
RUN apt-get update && apt-get install netcat-openbsd -y
# Add Poetry to PATH
ENV PATH="/root/.local/bin:$PATH"
# Copy the current directory contents into the container at /app
COPY . /app
RUN poetry lock --no-update
# Install Python dependencies
RUN poetry install --no-root
# Add wait-for-it.sh script to the container
COPY wait-for-it.sh /wait-for-it.sh
RUN chmod +x /wait-for-it.sh
# Make port 8000 available to the world outside this container
EXPOSE 8000
# Copy entrypoint script to the container
COPY startup.sh /startup.sh
RUN chmod +x /startup.sh
# Run the entrypoint script
CMD ["/startup.sh"]By ensuring that the services communicate using the correct Docker network service names and that dependencies are properly managed, you should be able to resolve the ECONNREFUSED error [1].
