The Juju team is proud to release Juju 2.7.3!
This is primarily a bug fix release of the stable 2.7 channel, with some additional useful tweaks.
Highlights
Provider-specific
VMware vSphere: custom root folder fix
There was an issue with the support for custom root folders which landed in 2.7.2.
This release addresses an issue where an attempt was made (and rejected due to permissions) to read the datacenter/vm root folder even if a custom folder had been specified.
Kubernetes improvements
Additional Custom Resource Definition attributes supported
CustomResourceDefinitions (CRDs) now support conversion and preserveUnknownFields attributes.
Validating webhook resources
Charms can now ask to create validating webhook resources. This extends the functionality implemented within Juju 2.7.2 to support for dynamically mutating webhook resources.
Add YAML like this to the k8s specific YAML passed to Juju via the pod-spec-set hook tool:
kubernetesResources:
validatingWebhookConfigurations:
pod-policy.example.com:
- name: "pod-policy.example.com"
rules:
- apiGroups: [""]
apiVersions: ["v1"]
operations: ["CREATE"]
resources: ["pods"]
scope: "Namespaced"
clientConfig:
service:
namespace: "example-namespace"
name: "example-service"
caBundle: "YXBwbGVz"
admissionReviewVersions: ["v1", "v1beta1"]
sideEffects: None
timeoutSeconds: 5
hostNetwork support
The hostNetwork attribute is now supported.
eg
kubernetesResources:
pod:
restartPolicy: OnFailure
activeDeadlineSeconds: 10
terminationGracePeriodSeconds: 20
securityContext:
runAsNonRoot: true
supplementalGroups: [1,2]
readinessGates:
- conditionType: PodScheduled
dnsPolicy: ClusterFirstWithHostNet
hostNetwork: true
