Deployment Overview of Curiosity on Server¶

Prerequisites and Basic Requirements¶

The deployment of Curiosity requires a Linux environment based on the Debian or Ubuntu distribution. The installation process involves system-level package updates and the installation of specific dependencies.

Operating System: Debian or Ubuntu.
Privileges: Root access or sudo privileges are required to execute package updates and install the application.
Network Connectivity: The server must have access to the internet to download the application package from GitHub and update system repositories.
Required Packages: The following system libraries and tools are installed as part of the deployment:
wget
curl
libc-dev
libsnappy1v5

Application Installation Process¶

The Curiosity application is installed as a native Debian package (.deb). The deployment script automatically retrieves the latest release version from the official GitHub repository and installs it using the apt package manager.

System Update: The installation begins by updating the APT cache and upgrading existing system packages to their latest versions.
Dependency Installation: Essential tools (wget, curl) and development libraries (libc-dev, libsnappy1v5) are installed if not already present.
Package Retrieval: The script dynamically fetches the latest .deb file from the curiosity-ai/curiosity-app-linux repository on GitHub.
Installation: The retrieved package is installed using the apt command.
Cleanup: Temporary installation files located in /tmp are removed immediately after the installation is complete.

File and Directory Structure¶

The application is installed as a system package, placing binaries and configuration files in standard Linux directories.

Temporary Download Location: /tmp (used transiently during installation).
System Package Location: Managed by the dpkg/apt system (typically /usr/bin, /usr/lib, or /etc depending on the package definition).
Configuration Files: Located in standard system configuration directories as defined by the Debian package.
Data Storage: Application data is stored in locations defined by the installed package, typically under /var/lib or user-specific directories.

Access Rights and Security¶

The installation process requires elevated privileges to modify system packages and libraries.

User Privileges: The installation must be run with root or sudo permissions.
Firewall: No specific firewall rules are defined in the provided configuration; standard server firewall policies apply.
Package Integrity: The application is installed via the official apt package manager, ensuring dependency resolution and integrity checks.

Starting, Stopping, and Updating¶

As Curiosity is installed as a native Debian package, service management is handled through standard Linux service commands or the apt package manager.

Update System Packages:
```
sudo apt update && sudo apt upgrade
```
Update Curiosity: To update the application to the latest version, the .deb package must be re-downloaded and re-installed using apt.
```
sudo apt install --reinstall curiosity
```
Service Management: If the package installs a systemd service, standard commands apply:
```
sudo systemctl start curiosity
sudo systemctl stop curiosity
sudo systemctl status curiosity
```
Note: Specific service names depend on the internal configuration of the installed .deb package.
