Flyway optionally supports loading configuration via environment variables.
The following environment variables are supported:
|FLYWAY_CONFIG_FILES||Comma-separated list of configuration files to load|
|FLYWAY_CONFIG_FILE_ENCODING||The encoding to use when loading configuration files|
|FLYWAY_URL||The jdbc url to use to connect to the database|
|FLYWAY_DRIVER||The fully qualified classname of the JDBC driver to use to connect to the database|
|FLYWAY_USER||The user to use to connect to the database|
|FLYWAY_PASSWORD||The password to use to connect to the database|
|FLYWAY_SCHEMAS||Comma-separated case-sensitive list of schemas managed by Flyway.
The first schema in the list will be automatically set as the default one during the migration. It will also be the one containing the schema history table.
|FLYWAY_TABLE||The name of Flyway's schema history table.
By default (single-schema mode) the schema history table is placed in the default schema for the connection provided by the datasource.
When the flyway.schemas property is set (multi-schema mode), the schema history table is placed in the first schema of the list.
|FLYWAY_LOCATIONS||Comma-separated list of locations to scan recursively for migrations. The location type is determined by its prefix.
Unprefixed locations or locations starting with
Locations starting with
|FLYWAY_JAR_DIRS||Comma-separated list of directories containing JDBC drivers and Java-based migrations|
|FLYWAY_SQL_MIGRATION_PREFIX||The file name prefix for Sql migrations|
|FLYWAY_REPEATABLE_SQL_MIGRATION_PREFIX||The file name prefix for repeatable Sql migrations|
|FLYWAY_SQL_MIGRATION_SEPARATOR||The file name separator for Sql migrations|
|FLYWAY_SQL_MIGRATION_SUFFIX||The file name suffix for Sql migrations|
|FLYWAY_MIXED||Whether to allow mixing transactional and non-transactional statements within the same migration|
|FLYWAY_GROUP||Whether to group all pending migrations together in the same transaction when applying them (only recommended for databases with support for DDL transactions)|
|FLYWAY_ENCODING||The encoding of Sql migrations|
|FLYWAY_PLACEHOLDER_REPLACEMENT||Whether placeholders should be replaced|
|FLYWAY_PLACEHOLDERS_<NAME>||Placeholders to replace in SQL migrations. For example to replace a placeholder named
|FLYWAY_PLACEHOLDER_PREFIX||The prefix of every placeholder|
|FLYWAY_PLACEHOLDER_SUFFIX||The suffix of every placeholder|
|FLYWAY_RESOLVERS||Comma-separated list of fully qualified class names of custom MigrationResolver implementations to be used in addition to the built-in ones for resolving Migrations to apply.|
|FLYWAY_SKIP_DEFAULT_RESOLVERS||Whether default built-in resolvers (sql, jdbc and spring-jdbc) should be skipped. If true, only custom resolvers are used.|
|FLYWAY_CALLBACKS||Comma-separated list of fully qualified class names of FlywayCallback implementations to use to hook into the Flyway lifecycle.|
|FLYWAY_SKIP_DEFAULT_CALLBACKS||Whether default built-in callbacks (sql) should be skipped. If true, only custom callbacks are used.|
|FLYWAY_TARGET||The target version up to which Flyway should consider migrations. Migrations with a higher version number will be ignored. The special value
|FLYWAY_OUT_OF_ORDER||Allows migrations to be run "out of order".
If you already have versions 1 and 3 applied, and now a version 2 is found, it will be applied too instead of being ignored.
|FLYWAY_VALIDATE_ON_MIGRATE||Whether to automatically call validate or not when running migrate.
For each sql migration a CRC32 checksum is calculated when the sql script is executed. The validate mechanism checks if the sql migration in the classpath still has the same checksum as the sql migration already executed in the database.
|FLYWAY_CLEAN_ON_VALIDATION_ERROR||Whether to automatically call clean or not when a validation error occurs.
This is exclusively intended as a convenience for development. Even tough we strongly recommend not to change migration scripts once they have been checked into SCM and run, this provides a way of dealing with this case in a smooth manner. The database will be wiped clean automatically, ensuring that the next migration will bring you back to the state checked into SCM.
Warning ! Do not enable in production !
|FLYWAY_IGNORE_MISSING_MIGRATIONS||Ignore missing migrations when reading the schema history table. These are migrations that were performed by an older deployment of the application that are no longer available in this version. For example: we have migrations available on the classpath with versions 1.0 and 3.0. The schema history table indicates that a migration with version 2.0 (unknown to us) has also been applied. Instead of bombing out (fail fast) with an exception, a warning is logged and Flyway continues normally. This is useful for situations where one must be able to deploy a newer version of the application even though it doesn't contain migrations included with an older one anymore.|
|FLYWAY_IGNORE_FUTURE_MIGRATIONS||Ignore future migrations when reading the schema history table. These are migrations that were performed by a newer deployment of the application that are not yet available in this version. For example: we have migrations available on the classpath up to version 3.0. The schema history table indicates that a migration to version 4.0 (unknown to us) has already been applied. Instead of bombing out (fail fast) with an exception, a warning is logged and Flyway continues normally. This is useful for situations where one must be able to redeploy an older version of the application after the database has been migrated by a newer one.|
|FLYWAY_CLEAN_DISABLED||Whether to disable clean. This is especially useful for production environments where running clean can be quite a career limiting move.|
|FLYWAY_BASELINE_ON_MIGRATE||Whether to automatically call baseline when migrate is executed against a non-empty schema with no metadata
This schema will then be baselined with the
This is useful for initial Flyway production deployments on projects with an existing DB.
Be careful when enabling this as it removes the safety net that ensures Flyway does not migrate the wrong database in case of a configuration mistake!
|FLYWAY_BASELINE_VERSION||The version to tag an existing schema with when executing baseline|
|FLYWAY_BASELINE_DESCRIPTION||The description to tag an existing schema with when executing baseline|
|FLYWAY_INSTALLED_BY||The username that will be recorded in the schema history table as having applied the migration|
