MongoSync Deployment

This project sets up a MongoSync deployment using Docker and Kubernetes.

Prerequisites

• Docker
• Kubernetes cluster
• kubectl configured to interact with your cluster

Dockerfile

The Dockerfile is based on Ubuntu and installs MongoSync. It exposes port 27182 and sets up the MongoSync command with the necessary arguments.

FROM ubuntu:latest
WORKDIR /tmp

ARG VERSION=1.6.1
ARG SRC_URI
ARG DST_URI
EXPOSE 27182

RUN apt-get update && apt-get install -y curl
RUN curl https://fastdl.mongodb.org/tools/mongosync/mongosync-ubuntu2004-x86_64-${VERSION}.tgz -o mongosync-ubuntu2004-x86_64-${VERSION}.tgz
RUN tar -xvzf mongosync-ubuntu2004-x86_64-${VERSION}.tgz
RUN cp mongosync-ubuntu2004-x86_64-${VERSION}/bin/mongosync /usr/local/bin/
RUN mongosync -v

CMD mongosync --cluster0 ${SRC_URI} --cluster1 ${DST_URI}

Deployment

The Kubernetes deployment is defined in deployment.yml. It creates a single replica of the MongoSync container, exposing port 27182 and setting environment variables for the source and destination URIs.

            limits:
              cpu: 1
              memory: 4Gi
      restartPolicy: Always
      terminationGracePeriodSeconds: 30

Building the Docker Image

To build the Docker image, run the following command:

docker build -t yourusername/mongosync:1.6.1 .

Deploying to Kubernetes

To deploy the application to your Kubernetes cluster, run:

kubectl apply -f deployment.yml

Environment Variables

• DST_URI: The URI of the destination MongoDB cluster.

Exposed Ports

• 27182: The port on which MongoSync listens.

Resources

• CPU Requests: 200m
