Gitea installation with Docker -- rootless or normal

Choosing between Docker rootless and Docker normal for installing Gitea depends on several factors related to security, ease of use, and your specific use case. Here's a comparison to help you decide:

Docker Normal Installation

Pros:

1. Performance: Generally, it has better performance since it runs as the root user and has fewer restrictions.
2. Compatibility: More likely to be compatible with a wider range of applications and tools without needing special configuration.
3. Ease of Use: Simpler setup process with fewer limitations compared to rootless Docker.

Cons:

1. Security: Running Docker with root privileges poses a higher security risk. If the Docker daemon or any container is compromised, it can potentially affect the entire host system.
2. Resource Access: Full access to system resources, which can be dangerous if not managed properly.

Use Case:

• Suitable for environments where performance is critical, and security concerns can be managed or are less of a priority.
• Ideal for development environments or controlled environments where the security risks are mitigated.

Docker Rootless Installation

Pros:

1. Security: Running Docker in rootless mode enhances security by isolating the Docker daemon from the root user. Even if a container is compromised, it has limited access to the host system.
2. User-Level: Can be run by a non-root user, reducing the attack surface and preventing privilege escalation.

Cons:

1. Performance: May have slightly reduced performance due to the additional security layers and limitations on resource access.
2. Compatibility: Not all features and tools may be compatible or as straightforward to use in rootless mode. Some configurations might require additional steps.

Use Case:

• Suitable for environments where security is a top priority, such as multi-user systems or public servers.
• Ideal for production environments where minimizing security risks is crucial.

Decision Factors

1. Security Requirements: If security is a primary concern, especially in production environments, Docker rootless is the better choice.
2. Performance Needs: If performance and compatibility are more critical, and you can manage security risks effectively, Docker normal might be preferable.
3. User Privileges: If you need to run Docker without root privileges, such as in a shared hosting environment, Docker rootless is necessary.
4. Environment: Consider the environment where Gitea will be running. For a personal or small-scale project with low risk, Docker normal might be more convenient. For larger or public-facing projects, Docker rootless provides additional security.

Recommendation for Gitea Installation

If you are planning to run Gitea in a production environment or on a server accessible by multiple users, Docker rootless is generally the safer option. However, if you are setting up Gitea for personal use, development, or in a controlled environment where performance is critical, Docker normal might be more suitable.
