Modules

flavors

Kaniko integration flavors.

Classes
KanikoImageBuilderConfig(warn_about_plain_text_secrets: bool = False, **kwargs: Any)

Bases: BaseImageBuilderConfig

Kaniko image builder configuration.

The env, env_from, volume_mounts and volumes attributes will be used to generate the container specification. They should be used to configure secrets and environment variables so that the Kaniko build container is able to push to the container registry (and optionally access the artifact store to upload the build context).

Attributes:

Name Type Description
kubernetes_context str

The Kubernetes context in which to run the Kaniko pod.
kubernetes_namespace str

The Kubernetes namespace in which to run the Kaniko pod. This namespace will not be created and must already exist.
executor_image str

The image of the Kaniko executor to use.
pod_running_timeout PositiveInt

The timeout to wait until the pod is running in seconds. Defaults to 300.
env List[Dict[str, Any]]

env section of the Kubernetes container spec.
env_from List[Dict[str, Any]]

envFrom section of the Kubernetes container spec.
volume_mounts List[Dict[str, Any]]

volumeMounts section of the Kubernetes container spec.
volumes List[Dict[str, Any]]

volumes section of the Kubernetes pod spec.
service_account_name Optional[str]

Name of the Kubernetes service account to use.
store_context_in_artifact_store bool

If True, the build context will be stored in the artifact store. If False, the build context will be streamed over stdin of the kubectl process that runs the build. In case the artifact store is used, the container running the build needs read access to the artifact store.
executor_args List[str]

Additional arguments to forward to the Kaniko executor. See https://github.com/GoogleContainerTools/kaniko#additional-flags for a full list of available arguments. Example: ["--compressed-caching=false"]

Modules

Kaniko image builder flavor.

Classes
KanikoImageBuilderConfig(warn_about_plain_text_secrets: bool = False, **kwargs: Any)

Bases: BaseImageBuilderConfig

Kaniko image builder configuration.

The env, env_from, volume_mounts and volumes attributes will be used to generate the container specification. They should be used to configure secrets and environment variables so that the Kaniko build container is able to push to the container registry (and optionally access the artifact store to upload the build context).

Attributes:

Name Type Description
kubernetes_context str

The Kubernetes context in which to run the Kaniko pod.
kubernetes_namespace str

The Kubernetes namespace in which to run the Kaniko pod. This namespace will not be created and must already exist.
executor_image str

The image of the Kaniko executor to use.
pod_running_timeout PositiveInt

The timeout to wait until the pod is running in seconds. Defaults to 300.
env List[Dict[str, Any]]

env section of the Kubernetes container spec.
env_from List[Dict[str, Any]]

envFrom section of the Kubernetes container spec.
volume_mounts List[Dict[str, Any]]

volumeMounts section of the Kubernetes container spec.
volumes List[Dict[str, Any]]

volumes section of the Kubernetes pod spec.
service_account_name Optional[str]

Name of the Kubernetes service account to use.
store_context_in_artifact_store bool

If True, the build context will be stored in the artifact store. If False, the build context will be streamed over stdin of the kubectl process that runs the build. In case the artifact store is used, the container running the build needs read access to the artifact store.
executor_args List[str]

Additional arguments to forward to the Kaniko executor. See https://github.com/GoogleContainerTools/kaniko#additional-flags for a full list of available arguments. Example: ["--compressed-caching=false"]
