branch-4.1: [opt](cloud) Support multiple config files in start.sh #63924#65162
Merged
Conversation
### What problem does this PR solve?
Support loading cloud start environment variables from multiple config
files without forcing deployments to rely on `process_name` as the only
config file name.
This keeps the default behavior of loading `${process_name}.conf`, and
adds support for `CONF_FILES` with comma-separated or
whitespace-separated entries, glob patterns, and absolute paths. Config
files are loaded in order, later files can override earlier files, while
variables already set before config loading keep priority.
Issue Number: close #xxx
Related PR: #xxx
Problem Summary: `cloud/script/start.sh` previously loaded only
`${process_name}.conf`, which made multi-instance or layered config
deployments harder to express.
### Release note
Support specifying multiple cloud config files through `CONF_FILES` in
`cloud/script/start.sh`.
