# Gitea with Let's Encrypt Using Docker Compose

# The complete installation guide is available on my website https://www.heyvaldemar.com/install-gitea-using-docker-compose/

# Change variables in the `.env` to meet your requirements.
# Note that the `.env` file should be in the same directory as `gitea-traefik-letsencrypt-docker-compose.yml`.

# Create networks for your services before deploying the configuration using the commands:
# `docker network create traefik-network`
# `docker network create gitea-network`

# Deploy Gitea using Docker Compose:
# `docker compose -f gitea-traefik-letsencrypt-docker-compose.yml -p gitea up -d`

# Backups
# The `backups` container in the configuration is responsible for the following:
# 1. **Database Backup**: Creates compressed backups of the PostgreSQL database using pg_dump.
# Customizable backup path, filename pattern, and schedule through variables like `POSTGRES_BACKUPS_PATH`, `POSTGRES_BACKUP_NAME`, and `BACKUP_INTERVAL`.
# 2. **Application Data Backup**: Compresses and stores backups of the application data on the same schedule. Controlled via variables such as `DATA_BACKUPS_PATH`, `DATA_BACKUP_NAME`, and `BACKUP_INTERVAL`.
# 3. **Backup Pruning**: Periodically removes backups exceeding a specified age to manage storage.
# Customizable pruning schedule and age threshold with `POSTGRES_BACKUP_PRUNE_DAYS` and `DATA_BACKUP_PRUNE_DAYS`.
# By utilizing this container, consistent and automated backups of the essential components of your instance are ensured.
# Moreover, efficient management of backup storage and tailored backup routines can be achieved through easy and flexible configuration using environment variables.

# # gitea-restore-database.sh Description
# This script facilitates the restoration of a database backup.
# 1. **Identify Containers**: It first identifies the service and backups containers by name, finding the appropriate container IDs.
# 2. **List Backups**: Displays all available database backups located at the specified backup path.
# 3. **Select Backup**: Prompts the user to copy and paste the desired backup name from the list to restore the database.
# 4. **Stop Service**: Temporarily stops the service to ensure data consistency during restoration.
# 5. **Restore Database**: Executes a sequence of commands to drop the current database, create a new one, and restore it from the selected compressed backup file.
# 6. **Start Service**: Restarts the service after the restoration is completed.
# To make the `gitea-restore-database.shh` script executable, run the following command:
# `chmod +x gitea-restore-database.sh`
# Usage of this script ensures a controlled and guided process to restore the database from an existing backup.

# # gitea-restore-application-data.sh Description
# This script is designed to restore the application data.
# 1. **Identify Containers**: Similarly to the database restore script, it identifies the service and backups containers by name.
# 2. **List Application Data Backups**: Displays all available application data backups at the specified backup path.
# 3. **Select Backup**: Asks the user to copy and paste the desired backup name for application data restoration.
# 4. **Stop Service**: Stops the service to prevent any conflicts during the restore process.
# 5. **Restore Application Data**: Removes the current application data and then extracts the selected backup to the appropriate application data path.
# 6. **Start Service**: Restarts the service after the application data has been successfully restored.
# To make the `gitea-restore-application-data.sh` script executable, run the following command:
# `chmod +x gitea-restore-application-data.sh`
# By utilizing this script, you can efficiently restore application data from an existing backup while ensuring proper coordination with the running service.
