[Improvement] Suggestions for Playground Startup Script Improvements

[orenccl]

Mainly suggested by @xunliu

1. Update Usage Prompt

Change the usage prompt in the startup script from:

echo "Usage: $0 [start | status | stop]"

to:

echo "Usage: $0 [start|stop|status]"

2. Optimize Port Status Output

Update the current port status output to display on a single line. For example:

• Current output: Port 8090 is ok.
• Suggested output: Port 8090, 9001 is ok.

3. Optimize Port In-Use Warning

Similarly, consolidate the port in-use warnings to a single line:

• Current output: xx is in use. Please check it.
• Suggested output: x1, x2 are in use. Please check them.

4. Remove Unnecessary Confirmation Prompt

Remove the following confirmation prompt to streamline the user experience:

Confirm the requirement is available in your OS [Y/n]:Y

5. Specify Tag for hello-world Image

Currently, the script includes the following command:

docker run --pull always hello-world >/dev/null 2>&1

To avoid unnecessary image downloads due to changes in the latest tag, specify a tag explicitly (e.g., 3.2.1).

6. Check Docker Resource Availability

The script includes a resource requirement message:

The playground requires 2 CPU cores, 8 GB of RAM, and 25 GB of disk storage to operate efficiently.

Currently, this is a text-based prompt. Consider using Docker commands to verify actual resource availability, especially ensuring that available disk space meets the 25GB requirement, to help ensure the Playground can operate smoothly.

I would like to work on this.
