Let’s get to the good stuff. You can spin up an EdgeDB instance with a single command.
$
edgedb instance create my_instanceThis creates a new instance named my_instance that runs the latest stable
version of EdgeDB. (EdgeDB itself will be automatically installed if it isn’t
already.) Alternatively you can specify a specific version with
--version.
$
edgedb instance create my_instance --version 2.1$
edgedb instance create my_instance --version nightlyWe can execute a query against our new instance with edgedb query. Specify
which instance to connect to by passing an instance name into the -I flag.
$
edgedb query "select 3.14" -I my_instance3.14
A single EdgeDB instance can contain multiple databases. Upon creation, an
instance contains a single database called edgedb. All queries and CLI
commands are executed against this database unless otherwise specified.
To create a new database:
$
edgedb database create newdb -I my_instanceWe can now execute queries against this new database by specifying it with the
--database/-d flag.
$
edgedb query "select 3.14" -I my_instance -d newdb3.14
Instances can be stopped, started, restarted, and destroyed.
$
edgedb instance stop -I my_instance$
edgedb instance start -I my_instance$
edgedb instance restart -I my_instance$
edgedb instance destroy -I my_instanceTo list all instances on your machine:
$
edgedb instance list┌────────┬──────────────────┬──────────┬────────────────┬──────────┐ │ Kind │ Name │ Port │ Version │ Status │ ├────────┼──────────────────┼──────────┼────────────────┼──────────┤ │ local │ my_instance │ 10700 │ 2.x+8421216 │ active │ │ local │ my_instance_2 │ 10701 │ 2.x+8421216 │ active │ │ local │ my_instance_3 │ 10702 │ 2.x+8421216 │ active │ └────────┴──────────────────┴──────────┴────────────────┴──────────┘
