Using sling conns

Here are examples of setting a connection named MARIADB. We must provide the type=mariadb property:

$ sling conns set MARIADB type=mariadb host=<host> user=<user> database=<database> password=<password> port=<port> 

# OR use url
$ sling conns set MARIADB url="mariadb://myuser:[email protected]:3306/mydatabase?tls=skip-verify"

Environment Variable

export MARIADB='mariadb://myuser:[email protected]:3306/mydatabase?tls=skip-verify'
export MARIADB='{ type: mariadb, user: "myuser", password: "mypass", host: "host.ip", port: 3306, database: "mydatabase", tls: "skip-verify" }'

Sling Env File YAML

See here to learn more about the sling env.yaml file.

connections:
  MARIADB:
    type: mariadb
    host: <host>
    user: <user>
    port: <port>
    database: <database>
    schema: <schema>
    password: <password>

  MARIADB_URL:
    url: "mariadb://myuser:[email protected]:3306/mydatabase?tls=skip-verify"

Database user creation

To allow Sling to access your database, we need to create a user with the proper privileges. Please follow the steps below:

1. First you'll need to login as a user with CREATE USER and GRANT OPTION privileges. Create a user sling (or whatever you prefer) by running :

   CREATE USER 'sling'@'%' IDENTIFIED BY '<password>';

2. If you are planning to load data into this connection, you need to grant the following privileges to that user so we can create tables in schema sling:

   CREATE SCHEMA sling;
   GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, CREATE TEMPORARY TABLES, CREATE VIEW ON sling.* TO 'sling'@'%';

3. If you are planning to extract data from this connection, you need to give permission to read the tables you'd like Sling to extract.

   -- To give read access to all tables in a specific schema
   GRANT SELECT ON <schema_name>.* TO  'sling'@'%';
