How to use the command 'doctl databases options' (with examples)

The doctl databases options command is used to enable the navigation of available options under each database engine. It provides various subcommands to retrieve information about available database engines, regions, slugs, and versions.

Use case 1: Run a doctl databases options command with an access token

Code:

doctl databases options command --access-token access_token

Motivation: This use case is useful when you want to run the doctl databases options command with a specific access token. An access token is required for authentication and authorization purposes when interacting with the DigitalOcean API using doctl.

Explanation:

• doctl databases options command is the base command to explore available options under each database engine.
• --access-token access_token is an optional flag that specifies the access token to authenticate the request with the DigitalOcean API. Replace access_token with your actual access token.

Example output:

OPTIONS
  --access-token string   DigitalOcean access token [$DO_ACCESS_TOKEN]
  --help                  Show this help message

Use case 2: Retrieve a list of the available database engines

Code:

doctl databases options engines

Motivation: This use case is helpful when you want to get a list of the available database engines. It allows you to see which engines are supported by DigitalOcean and choose the appropriate one for your needs.

Explanation:

• doctl databases options engines is a subcommand that lists the available database engines.

Example output:

- pg (PostgreSQL)
- mysql (MySQL)
- redis (Redis)
- mongodb (MongoDB)

Use case 3: Retrieve a list of the available regions for a given database engine

Code:

doctl databases options regions --engine pg|mysql|redis|mongodb

Motivation: This use case is useful when you want to find out the available regions for a specific database engine. It helps you determine which regions are supported and choose the most suitable one for your application’s latency and compliance requirements.

Explanation:

• doctl databases options regions is a subcommand that lists the available regions for a given database engine.
• --engine pg|mysql|redis|mongodb is a required flag that specifies the database engine for which you want to retrieve the available regions. Choose one of the available options: pg for PostgreSQL, mysql for MySQL, redis for Redis, or mongodb for MongoDB.

Example output:

- nyc1 (New York 1)
- nyc3 (New York 3)
- sfo2 (San Francisco 2)
- ams3 (Amsterdam 3)

Use case 4: Retrieve a list of the available slugs for a given database engine

Code:

doctl databases options slugs --engine pg|mysql|redis|mongodb

Motivation: This use case is helpful when you want to get a list of available slugs for a specific database engine. Slugs are used to uniquely identify a database cluster and are part of the cluster’s endpoint URL. Knowing the available slugs can help you choose a suitable name for your database cluster.

Explanation:

• doctl databases options slugs is a subcommand that lists the available slugs for a given database engine.
• --engine pg|mysql|redis|mongodb is a required flag that specifies the database engine for which you want to retrieve the available slugs. Choose one of the available options: pg for PostgreSQL, mysql for MySQL, redis for Redis, or mongodb for MongoDB.

Example output:

- example-slug-1
- example-slug-2
- example-slug-3

Use case 5: Retrieve a list of the available versions for a given database engine

Code:

doctl databases options versions --engine pg|mysql|redis|mongodb

Motivation: This use case is useful when you want to know the available versions for a specific database engine. Different database engine versions may have different features and compatibility. Understanding the available versions allows you to select the most suitable one for your application’s requirements.

Explanation:

• doctl databases options versions is a subcommand that lists the available versions for a given database engine.
• --engine pg|mysql|redis|mongodb is a required flag that specifies the database engine for which you want to retrieve the available versions. Choose one of the available options: pg for PostgreSQL, mysql for MySQL, redis for Redis, or mongodb for MongoDB.

Example output:

- 9.6
- 10.3
- 11.4
- 12.2

Conclusion:

The doctl databases options command provides a versatile set of subcommands to explore available options under each database engine. Whether you need to retrieve a list of database engines, regions, slugs, or versions, this command has got you covered. By leveraging this command, you can gather valuable information about DigitalOcean’s managed databases and make informed decisions based on your application’s needs.
