Docker image

[agneevX]

Hello,

An official multi-arch Docker image would make deployments very easy.

But the deployment is already easy: a single installer command.

Where are you deploying this to?

I'm deploying to both local and remote servers that run Docker.

Quick and dirty, could probably be improved to use alpine, but this works.

# Use a base image with curl installed
FROM ubuntu:latest

# Set the working directory
WORKDIR /app

# Download the DNS proxy server
RUN apt-get update && \
    apt-get install -y curl ca-certificates iproute2  && \
    rm -rf /var/lib/apt/lists/*

# Download the DNS proxy server
RUN curl -L -o ctrld https://assets.controld.com/ctrld/linux/amd64/ctrld && \
    chmod +x ctrld

# Expose the required ports
EXPOSE 53/tcp 53/udp

# Start the DNS proxy server with the supplied argument
CMD ["sh", "-c", "./ctrld run --listen=0.0.0.0:53 --primary_upstream=$arg"]

Then

docker build -t docker-ctrld .

Then

docker run -d --name=ctrld -p 53:53/tcp -p 53:53/udp -e arg=https://freedns.controld.com/p2 docker-ctrld
