2 hours ago we can also use kubernetes as a reference for naming the commands.
Based on Kubernetes commands, here's a proposed set of Sugar commands that map to both Docker Swarm and Docker Compose commands. This unified command set aims to provide a consistent interface inspired by Kubernetes, allowing users to manage services across different orchestration platforms seamlessly.

Additional Notes
- Configuration Files: Sugar can use Docker Compose YAML files as configuration, similar to Kubernetes manifest files.
- Context Awareness: Sugar can determine whether to use Docker Compose or Docker Swarm based on the context or a specified flag (e.g.,
--orchestrator [compose|swarm]). - Error Handling: Commands not supported by an orchestrator should provide informative messages.
- Extensibility: Additional Kubernetes-inspired commands can be added as needed, with careful mapping to Docker functionalities.
- Consistency: Using Kubernetes command patterns helps users familiar with Kubernetes to adapt quickly to Sugar.
By aligning Sugar's command set with Kubernetes commands, you provide users with a familiar interface that abstracts the underlying differences between Docker Swarm and Docker Compose. This approach simplifies container orchestration and improves developer productivity.
In order to support docker swarm, we need to rewrite the CLI commands to something more generic and create a map for docker compose and swarm.
Here's a proposal for a new Sugar CLI API that abstracts common container orchestration commands, mapping them to both Docker Compose and Docker Swarm. This unified API aims to provide a consistent user experience regardless of the underlying orchestration tool.
this should be done before #124

Configuration File Detection: Sugar can detect whether to use Docker Compose or Docker Swarm based on a configuration flag or the presence of Swarm-specific settings.
Context Flag: Introduce a global
--contextflag to specify the orchestration tool (e.g.,--context composeor--context swarm).Error Handling: Provide informative errors when a command isn't supported in the current context.
Extended Commands: For Swarm-specific features like rolling updates, health checks, and secret management, extend Sugar with additional commands as needed.
Aliases and Shortcuts: Allow for command aliases to make the CLI more intuitive.
Example Usage
Deploy Services
Scale a Service
View Logs
Execute Command in a Service
Update a Service
Stop Services
By defining these commands, Sugar provides a unified interface that abstracts away the differences between Docker Compose and Docker Swarm. This allows users to manage their containerized applications seamlessly, regardless of the underlying orchestration platform.
