Research direction

Use the linked install-LXD and ceph-csi documentation as references, and inspect the repository's documentation structure to determine where this tutorial belongs. Validate the provided Juju, Kubernetes, LXD, and Ceph commands in sequence; done means the production-ready environment tutorial covers the proposed setup end to end.

Written by the indexing model from the issue text.

Description

Using ck8s 1.32 charm + virt-type=virtual-machine + ceph-csi.

Potential starting point:

sudo snap install juju --channel=3.6/stable
sudo sysctl -w fs.inotify.max_user_instances=1024
sudo sysctl -w fs.inotify.max_user_watches=1048576

# Disable IPv6
echo "net.ipv6.conf.all.disable_ipv6=1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.default.disable_ipv6=1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.lo.disable_ipv6=1" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

lxd init --auto
juju bootstrap lxd
juju add-model ck8s

# https://documentation.ubuntu.com/canonical-kubernetes/latest/charm/howto/install/install-lxd/
juju deploy k8s --channel=1.33/beta --revision=1024 --constraints='cores=8 mem=16G root-disk=40G virt-type=virtual-machine'

# https://documentation.ubuntu.com/canonical-kubernetes/latest/charm/howto/ceph-csi/
juju deploy -n 1 ceph-mon \
    --constraints "cores=2 mem=4G root-disk=16G" \
    --config monitor-count=1 \
    --config expected-osd-count=1

juju deploy -n 1 ceph-osd \
    --constraints "cores=2 mem=4G root-disk=16G virt-type=virtual-machine" \
    --storage osd-devices=1G,1 --storage osd-journals=1G,1

juju integrate ceph-osd:mon ceph-mon:osd

CEPH_NS=ceph-ns  # kubernetes namespace for the ceph driver
juju deploy ceph-csi \
  --config provisioner-replicas=1 \
  --config namespace="${CEPH_NS}" \
  --config create-namespace=true
juju integrate ceph-csi k8s:ceph-k8s-info
