A typical database instance could be your on-premises MySQL instance, a PostgreSQL cluster, an AWS RDS instance etc. Each Database Instance belongs to an Environment.
Go to Instances and Add Instance.
For Host or socket, the screenshot assumes you run Bytebase inside Docker and try to connect to a database instance on the same host, thus it uses 
By default, Bytebase doesn’t automatically sync the instance schema. You can set a Scan Interval to ask Bytebase to sync the schema periodically.
Prerequisites
- Workspace Admin or Workspace DBA role
Add instance
If you choose to use sample data during onboarding, Bytebase will start two embedded sample PostgreSQL instances accessible from
/tmp:8083 and /tmp:8084.
For Host or socket, the screenshot assumes you run Bytebase inside Docker and try to connect to a database instance on the same host, thus it uses host.docker.internal. Check out Instance Connection Configuration for the detailed guide.
Sync instance schema
After instance is added, click Sync Now to synchronize the instance schema such as its containing databases to Bytebase.
By default, Bytebase doesn’t automatically sync the instance schema. You can set a Scan Interval to ask Bytebase to sync the schema periodically.
