The scalability of StarlingX is awesome, that it can be functional with only 3 nodes and scale to 100+ nodes in the future. This is perfect for devops use case. A new project might only have a few servers at the beginning and need to scale it in the future.

This wiki assumes that the user already deployed a StarlingX and wants to practice devops for their projects. It will share some BKMs and provide an example StarlingX App for such use case.

Install StarlingX

Refer to: StarlingX R2.0 Installation

CephFs Setup

DevOps App will use Cephfs for persistent volumes. It needs to setup CephFS on starlingx before install App.

• Create Ceph user and key

ceph auth get-or-create client.stx-devops mon 'allow r' mds 'allow r, allow rw path=/stx-devops' osd 'allow rw'

• Create Cephfs pools

ceph osd pool create fs_data 2048
ceph osd pool create fs_metadata 256
ceph fs new cephfs fs_metadata fs_data

• Start mds manually

# on controller-0
/usr/bin/ceph-mds --cluster ceph --id controller-0 --hot-standby 0
# on controller-1
/usr/bin/ceph-mds --cluster ceph --id controller-1 --hot-standby 0

• init folders for stx-devops

sudo mkdir -p /mnt/mycephfs
sudo mount -t ceph controller-0:6789:/ /mnt/mycephfs
sudo mkdir -p -m 777 /mnt/mycephfs/stx-devops/jenkins-master
sudo mkdir -p -m 777 /mnt/mycephfs/stx-devops/pub
sudo mkdir -p -m 777 /mnt/mycephfs/stx-devops/registry
sudo mkdir -p -m 777 /mnt/mycephfs/stx-devops/docker-io-mirror
