SoftwareConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)Specifies the selection and configuration of software inside the environment.

|---|---|
| Name | Description |
image_version |
str
The version of the software running in the environment. This encapsulates both the version of Cloud Composer functionality and the version of Apache Airflow. It must match the regular expression composer-([0-9]+(\.[0-9]+\.[0-9]+(-preview\.[0-9]+)?)?|latest)-airflow-([0-9]+(\.[0-9]+(\.[0-9]+)?)?).
When used as input, the server also checks if the provided
version is supported and denies the request for an
unsupported version.
The Cloud Composer portion of the image version is a full
semantic version __, or an alias in
the form of major version number or latest. When an
alias is provided, the server replaces it with the current
Cloud Composer version that satisfies the alias.
The Apache Airflow portion of the image version is a full
semantic version that points to one of the supported Apache
Airflow versions, or an alias in the form of only major or
major.minor versions specified. When an alias is provided,
the server replaces it with the latest Apache Airflow
version that satisfies the alias and is supported in the
given Cloud Composer version.
In all cases, the resolved image version is stored in the
same field.

airflow_config_overrides |
MutableMapping[str, str]
Optional. Apache Airflow configuration properties to override. Property keys contain the section and property names, separated by a hyphen, for example "core-dags_are_paused_at_creation". Section names must not contain hyphens ("-"), opening square brackets ("["), or closing square brackets ("]"). The property name must not be empty and must not contain an equals sign ("=") or semicolon (";"). Section and property names must not contain a period ("."). Apache Airflow configuration property names must be written in snake_case __.
Property values can contain any character, and can be
written in any lower/upper case format.
Certain Apache Airflow configuration property values are
blocked __,
and cannot be overridden.

pypi_packages |
MutableMapping[str, str]
Optional. Custom Python Package Index (PyPI) packages to be installed in the environment. Keys refer to the lowercase package name such as "numpy" and values are the lowercase extras and version specifier such as "==1.12.0", "[devel,gcp_api]", or "[devel]>=1.8.2, <1.9.2". to="" specify="" a="" package="" without="" pinning="" it="" to="" a="" version="" specifier,="" use="" the="" empty="" string="" as="" the="" value.=""> |
env_variables |
MutableMapping[str, str]
Optional. Additional environment variables to provide to the Apache Airflow scheduler, worker, and webserver processes. Environment variable names must match the regular expression `` a-zA-Z_][a-zA-Z0-9_]*``. They cannot specify Apache
Airflow software configuration overrides (they cannot match
the regular expression AIRFLOW__[A-Z0-9_]+__[A-Z0-9_]+),
and they cannot match any of the following reserved names:
- AIRFLOW_HOME
- C_FORCE_ROOT
- CONTAINER_NAME
- DAGS_FOLDER
- GCP_PROJECT
- GCS_BUCKET
- GKE_CLUSTER_NAME
- SQL_DATABASE
- SQL_INSTANCE
- SQL_PASSWORD
- SQL_PROJECT
- SQL_REGION
- SQL_USER

python_version |
str
Optional. The major version of Python used to run the Apache Airflow scheduler, worker, and webserver processes. Can be set to '2' or '3'. If not specified, the default is '3'. Cannot be updated. This field is only supported for Cloud Composer environments in versions composer-1.\ *.*-airflow-*.*.*. Environments in newer versions always use Python major version 3. |
scheduler_count |
int
Optional. The number of schedulers for Airflow. This field is supported for Cloud Composer environments in versions composer-1.\ *.*-airflow-2.*.*. |
