Postgres

Drone comes with support for Postgres as an alternate database engine. To enable Postgres, you should specify the following environment variables:

DATABASE_DRIVER="postgres"
DATABASE_CONFIG="postgres://root:pa55word@127.0.0.1:5432/postgres"

Postgres configuration

The following is the standard URI connection scheme:

postgres://[username:password@]host[:port]/[dbname][?options]

The components of this string are:

• postgres:// required prefix
• username:password@ optional. Use these credentials when connecting to the Postgres instance.
• host server address to connect to. It may be a hostname, IP address, or UNIX domain socket.
• :port optional. The default value is :5432 if not specified.
• dbname name of the database to connect to
• ?options connection specific options

This is an example connection string:

postgres://root:pa55word@127.0.0.1:5432/postgres

Postgres options

This section lists all connection options used in the connection string format. Connection options are pairs in the following form: name=value. The value is always case sensitive. Separate options with the ampersand (i.e. &) character:

• sslmode initiates the connection with TLS/SSL (disable, require, verify-ca, verify-full)
• connect_timeout maximum wait for connection, in seconds.
• sslcert cert file location. The file must contain PEM encoded data.
• sslkey key file location. The file must contain PEM encoded data.
• sslrootcert location of the root certificate file. The file must contain PEM encoded data.
