+# MySQL Backup Docker Container
+
+This Docker container is designed to backup MySQL databases and upload the backups to Google Cloud Storage. It also handles the management of a Cloud SQL Proxy connection to securely connect to Google Cloud SQL instances without having to expose them publicly.
+
+## Features
+
+- **Database Backups**: Supports backing up multiple databases configured via environment variables.
+- **Google Cloud Storage**: Uploads database backups directly to a configured GCS bucket.
+- **Cloud SQL Proxy Management**: Handles the lifecycle of a Cloud SQL Proxy connection to secure database connections.
+
+## Prerequisites
+
+- A Google Cloud account and a configured GCS bucket.
+- Access to a Google Cloud SQL instance or any MySQL server.
+- Docker installed on your machine or Kubernetes cluster.
+
+## Configuration
+
+### Environment Variables
+
+This container uses the following environment variables:
+
+- `MYSQL_HOST`: The hostname of the MySQL server.
+- `MYSQL_USER`: The username for the MySQL database.
+- `MYSQL_PASSWORD`: The password for the MySQL database (use Kubernetes secrets for Kubernetes deployments).
+- `MYSQL_DATABASES`: Comma-separated list of databases to backup.
+- `GCS_BUCKET`: The Google Cloud Storage bucket where backups will be stored.
+- `PROXY_PORT`: The port on which the MySQL server or proxy is accessible (default is 3306).
+- `PROXY_QUIT_URL`: URL to send the quit command to Cloud SQL Proxy.
+
+### Volumes
+
+- `/backup`: This directory is where the database dumps are temporarily stored before being uploaded to GCS.
+
+## Using the Docker Container
+
+### Running Locally
+
+```sh
+docker run -e MYSQL_HOST='your-mysql-host' -e MYSQL_USER='user' -e MYSQL_PASSWORD='password' \
+-e MYSQL_DATABASES='db1,db2' -e GCS_BUCKET='your-gcs-bucket' \
+-e PROXY_QUIT_URL='http://localhost:9091/quitquitquit' \
+-v your-local-backup-dir:/backup \
+your-docker-image
+```
+
+### Deployment in Kubernetes
+
+You can deploy this container in a Kubernetes cluster as part of a CronJob. Refer to the included `kubernetes-cronjob.yaml` file for a sample deployment configuration.
+
+## Building the Docker Image
+
+To build this image from the Dockerfile:
