Description

When I run `airflow upgrade` when upgrading from 1.10.1 to 1.10.4, this is the error that I get:

 

```

sqlalchemy.exc.IntegrityError: (_mysql_exceptions.IntegrityError) (1215, 'Cannot add foreign key constraint')sqlalchemy.exc.IntegrityError: (_mysql_exceptions.IntegrityError) (1215, 'Cannot add foreign key constraint')[SQL: CREATE TABLE task_reschedule ( id INTEGER NOT NULL AUTO_INCREMENT,  task_id VARCHAR(250) NOT NULL,  dag_id VARCHAR(250) NOT NULL,  execution_date TIMESTAMP(6) NOT NULL,  try_number INTEGER NOT NULL,  start_date TIMESTAMP(6) NOT NULL,  end_date TIMESTAMP(6) NOT NULL,  duration INTEGER NOT NULL,  reschedule_date TIMESTAMP(6) NOT NULL,  PRIMARY KEY (id),  CONSTRAINT task_reschedule_dag_task_date_fkey FOREIGN KEY(task_id, dag_id, execution_date) REFERENCES task_instance (task_id, dag_id, execution_date))

```

 

Database: Managed Mysql on Azure

Airflow webserver, scheduler and worker are containerized using an Ubuntu docker image.

To upgrade, I stopped the containers, then started one container with `bash` as the foreground process.

 

```

pip install apache-airflow==1.10.4

airflow upgradedb

```
