Check for compatibility between Airflow versions

Apache Airflow Upgrade Check

This package aims to easy the upgrade journey from Apache Airflow 1.10 to 2.0.

While we have put a lot of effort in to making this upgrade as painless as possible, with many changes providing upgrade path (where the old code continues to work and prints out a deprecation warning) there were unfortunately some breaking changes where we couldn't provide a compatibility shim.

The recommended upgrade path to get to Airflow 2.0.0 is to first upgrade to the latest release in the 1.10 series (at the time of writing: 1.10.14) and to then run this script.

pip install apache-airflow-upgrade-check
airflow upgrade_check

This will then print out a number of action items that you should follow before upgrading to 2.0.0 or above.

The exit code of the command will be 0 (success) if no problems are reported, or 1 otherwise.

For example:

============================================= STATUS =============================================

Legacy UI is deprecated by default......................................................SUCCESS
Users must set a kubernetes.pod_template_file value.....................................FAIL
Changes in import paths of hooks, operators, sensors and others.........................FAIL
Remove airflow.AirflowMacroPlugin class.................................................SUCCESS
Jinja Template Variables cannot be undefined............................................SUCCESS
Fernet is enabled by default............................................................FAIL
Logging configuration has been moved to new section.....................................SUCCESS
Connection.conn_id is not unique........................................................SUCCESS
GCP service account key deprecation.....................................................SUCCESS
Users must delete deprecated configs for KubernetesExecutor.............................FAIL
Changes in import path of remote task handlers..........................................SUCCESS
Chain between DAG and operator not allowed..............................................SUCCESS
SendGrid email uses old airflow.contrib module..........................................SUCCESS
Connection.conn_type is not nullable....................................................SUCCESS
Found 16 problems.

======================================== RECOMMENDATIONS =========================================

Users must set a kubernetes.pod_template_file value
---------------------------------------------------
In Airflow 2.0, KubernetesExecutor Users need to set a pod_template_file as a base
value for all pods launched by the KubernetesExecutor


Problems:

  1.  Please create a pod_template_file by running `airflow generate_pod_template`.
This will generate a pod using your aiflow.cfg settings

...

Additionally you can use "upgrade config" to:

• specify rules you would like to ignore
• extend the check using custom rules

For example:

airflow upgrade_check --config=/files/upgrade.yaml

the configuration file should be a proper yaml file similar to this one:

ignored_rules:
  - LegacyUIDeprecated
  - ConnTypeIsNotNullableRule
  - PodTemplateFileRule

custom_rules:
  - path.to.upgrade_module.VeryCustomCheckClass
  - path.to.upgrade_module.VeryCustomCheckClass2
