gel migration apply​
Once the migration scripts are in place the changes can be applied to the database by this command:
gel migration apply [options]The tool will find all the unapplied migrations in
dbschema/migrations/ directory and sequentially run them on the
target instance.
Gel Cloud CI users and scripters
When scripting a migrate/migration apply for a Gel Cloud
instance, do not use gel login to authenticate. Instead, you should
generate a secret key in the Gel Cloud UI or by running
gel cloud secretkey create and set the
GEL_SECRET_KEY environment variable to your secret key. Once this
variable is set to your secret key, logging in is no longer required.
Options​
The migration apply command runs on the database it is connected
to. For specifying the connection target see connection options.
- --quiet
-
Do not print any messages, only indicate success by exit status.
- --schema-dir=schema-dir
-
Directory where the schema files are located. Defaults to
./dbschema. - --to-revision=to-revision
-
Upgrade to a specified revision.
Unique prefix of the revision can be specified instead of full revision name.
If this revision is applied, the command is no-op. The command ensures that this revision present, but it's not an error if more revisions are applied on top.
- --dev-mode
-
Apply the current schema changes on top of the current migration history, without having created a new migration. This works the same way as gel watch but without starting a long-running watch task.
