I am opening this as a Draft PR to verify the following.
For more details, please refer to the changes.

Note - The test to create infrastructure on AWS in MapUI has passed.

@seokho-son
Is it okay to upgrade to Spider v0.12.37?

@powerkimhub
I suggest improving environment variables to prevent special character encoding errors.
Is this possible?

(As-Is)

- SPIDER_METADB_URL=postgresql://${SP_POSTGRES_USER:-spider}:${SP_POSTGRES_PASSWORD:-spider}@cb-spider-postgres:5432/${SP_POSTGRES_DB:-cb_spider}

(To-Be)

- SPIDER_POSTGRES_ENDPOINT=cb-spider-postgres:5432
- SPIDER_POSTGRES_DATABASE=${SP_POSTGRES_DB:-cb_spider}
- SPIDER_POSTGRES_USER=${SP_POSTGRES_USER:-spider}
- SPIDER_POSTGRES_PASSWORD=${SP_POSTGRES_PASSWORD:-spider}

@seokho-son
Please, review the script changes.

The updates are to resolve the following issue.

From Spider v0.12.38, MetaDB can be configured in three modes.
Please refer to the following options and guides.

• Default Mode: SQLite
• PostgreSQL URL Mode
• PostgreSQL Key-Value Mode

Reference guides:

• setup.env

• CB-Spider Server Configuration

• Start with PostgreSQL Meta DB (Key-value Mode)

@powerkimhub FYI, Spider v0.12.38 seems not available yet. I am waiting for it.
