Summary: Error initialising airflow DB with MySQL non-boolean
check constraint
Key: AIRFLOW-4995
URL: https://issues.apache.org/jira/browse/AIRFLOW-4995
Project: Apache Airflow
Issue Type: Bug
Components: database
Affects Versions: 1.10.3
Reporter: pemontto
I'm currently unable to configure Airflow with a MySQL backend due to an error
during DB initialisation.
Error message while running airflow initdb:
{code:java}
An expression of non-boolean type specified to a check constraint
'kube_resource_version_one_row_id'."{code}
Triggered from this statement:
{code:java}
CREATE TABLE kube_resource_version (
one_row_id BOOL NOT NULL DEFAULT true,
resource_version VARCHAR(255),
PRIMARY KEY (one_row_id),
CONSTRAINT kube_resource_version_one_row_id CHECK (one_row_id),
CHECK (one_row_id IN (0, 1))
){code}
Airflow version: v1.10.3
MySQL:
{code:java}
mysql> SELECT @@version;
+-----------+
