DnsPolicy

class aws_cdk.aws_batch.DnsPolicy(value)

Bases: Enum

The DNS Policy for the pod used by the Job Definition.

See:: https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/#pod-s-dns-policy

Attributes

CLUSTER_FIRST: Any DNS query that does not match the configured cluster domain suffix, such as "www.kubernetes.io", is forwarded to an upstream nameserver by the DNS server. Cluster administrators may have extra stub-domain and upstream DNS servers configured.

CLUSTER_FIRST_WITH_HOST_NET

For Pods running with hostNetwork, you should explicitly set its DNS policy to CLUSTER_FIRST_WITH_HOST_NET.

Otherwise, Pods running with hostNetwork and CLUSTER_FIRST will fallback to the behavior of the DEFAULT policy.

DEFAULT: The Pod inherits the name resolution configuration from the node that the Pods run on.
