+# MongoDB ReplicaSet Setup
+
+This repository contains the necessary scripts and configurations to set up a MongoDB ReplicaSet using Docker. The setup
+includes initializing the ReplicaSet, creating a database user, and configuring MongoDB to run with authentication and a
+key file for secure communication between replica set members.
+
+## Table of Contents
+
+- [Prerequisites](#prerequisites)
+- [Configuration](#configuration)
+- [Usage](#usage)
+- [Scripts](#scripts)
+- [Dockerfile](#dockerfile)
+
+## Prerequisites
+
+- Docker installed on your machine.
+- A Docker registry to push the built image (optional).
+- Environment variables configured for MongoDB setup.
+
+## Configuration
+
+The following environment variables are required for the setup:
+
+| Variable                          | Type   | Description                                                         |
+|-----------------------------------|--------|---------------------------------------------------------------------|
+| `MONGO_DOMAIN`                    | string | The domain or IP address of the MongoDB instance.                   |
+| `MONGO_PORT`                      | number | The port on which MongoDB will run.                                 |
+| `MONGO_REPLICA_SET_NAME`          | string | The name of the MongoDB ReplicaSet.                                 |
+| `MONGO_INITDB_DATABASE`           | string | The initial database to create.                                     |
+| `MONGO_INITDB_ROOT_USERNAME_FILE` | secret | Path to the file containing the root username.                      |
+| `MONGO_INITDB_ROOT_PASSWORD_FILE` | secret | Path to the file containing the root password.                      |
+| `MONGO_PROJECTDB_USERNAME_FILE`   | secret | Path to the file containing the project database username.          |
+| `MONGO_PROJECTDB_PASSWORD_FILE`   | secret | Path to the file containing the project database password.          |
+| `MONGO_KEY_FILE_PATH`             | secret | Path to the key file for MongoDB authentication.                    |
+| `MONGO_KEY_FILE_TARGET_PATH`      | secret | Target path where the key file will be copied inside the container. |
+
+## Usage
+
+1. **Clone the repository:**
+   ```bash
+   git clone https://git.n08i40k.ru/n08i40k/mongodb-replset.git
+   cd mongodb-replset
+   ```
+
+2. **Build the Docker image:**
+   ```bash
+   docker build -t mongodb-replset .
+   ```
+
+3. **Run the Docker container:**
+   ```bash
+   docker run -d \
+     --name mongodb-replset \
+     -e MONGO_DOMAIN=mongodb.example.tdl \
+     -e MONGO_PORT=27017 \
+     -e MONGO_REPLICA_SET_NAME=rs0 \
+     -e MONGO_INITDB_DATABASE=example \
+     -e MONGO_INITDB_ROOT_USERNAME_FILE=/run/secrets/db_root_username \
+     -e MONGO_INITDB_ROOT_PASSWORD_FILE=/run/secrets/db_root_password \
+     -e MONGO_PROJECTDB_USERNAME_FILE=/run/secrets/db_username \
+     -e MONGO_PROJECTDB_PASSWORD_FILE=/run/secrets/db_password \
+     -e MONGO_KEY_FILE_PATH=/run/secrets/db_key_file \
+     -e MONGO_KEY_FILE_TARGET_PATH=/root/db_key_file \
+     mongodb-replset
+   ```
+
+## Scripts
+
+### `rs-init.sh`
+
+This script initializes the MongoDB ReplicaSet and creates a user with read-write permissions on the specified database.
+
+### `start.sh`
+
+This script is the entry point for the Docker container. It checks if the ReplicaSet is already initialized and, if not,
+initializes it using `rs-init.sh`. It also copies the key file to the specified location and starts the MongoDB instance
+with the appropriate configuration.
+
+## Dockerfile
+
+The `Dockerfile` is based on the official MongoDB image and includes the necessary scripts and configurations to set up
+a MongoDB ReplicaSet. It sets the working directory, copies the scripts, and defines the entry point and command to
+start MongoDB with the required options.
