Volcano is a batch system built on Kubernetes.
It provides a suite of mechanisms that are commonly required by many classes of batch & elastic workload including: machine learning/deep learning, bioinformatics/genomics and other "big data" applications. These types of applications typically run on generalized domain frameworks like TensorFlow, Spark, Ray, PyTorch, MPI, etc, which Volcano integrates with.

The suite of Volcano charms can be deployed within any kubernetes cluster so long as one has a valid admin token in a kubeconfig.
If deploying to an existing machine based juju controller, you'll first need to add a kubernetes-cloud with add-k8s
KUBECONFIG=path/to/my/kubeconfig juju add-k8s k8s-cloudNext, create a kubernetes namespace for volcano with a juju model
juju add-model volcano-systemThen deploy the bundle from charmhub
juju deploy volcano --trustjuju add-model volcano-system
juju deploy volcano-admission --trust
juju deploy volcano-controllers --trust
juju deploy volcano-scheduler --trustThe volcano admission service is exposed as a service on port 443 for internal communication and comes by default with self-signed certificates for this service. Its possible to relate to a certificate provider and have its certs generated by a trusted third-party like vault or easyrsa.
CERT_MODEL=<name of certificate model>
juju switch $CERT_MODEL
juju offer <certificate-application>:client certificates
juju switch volcano-system
juju consume admin/${CERT_MODEL}.certificates
juju relate volcano-admission:certificates certificates-
