UCP: Support specify configuration file of TiDB/TiKV/PD when starting playground

[lonng]

Description

Currently, we cannot specify the configuration file for the internal component of the playground, we should support this feature.

e.g tiup playground --db.config ~/conf/db.config.toml --kv.config ~/conf/kv.config.toml

Hi, i'd like to check some points here.

I think we just need to specify host, port, status port and number of TiDB/TiKV/pd in the configuration file. Is that right?

Hi @chenlx0, thanks for your interesting in this issue.

The configuration file is specified by the user, eg:

tiup playground --kv 3 --db 3 --pd 3 --pd.config ~/custom.pd.toml

This task allows the users to specify the configuration file for the specific component.
