Self Hosted Cloud Services

This repository includes information about my own Self Hosted Cloud Services based open source software running on Kubernetes on Raspberry PI cluster:

Tasks done and things to do

The current project status can be check in the Kanban board. The below information includes the configuration details.

Things to Do:

  • K3S
  • MetalLB
  • PiHole
  • Minio
  • OpenFaas
  • OpenVPN
  • NextCloud
  • Selfhosted apps
  • TOR Gateway
  • OpenHub

Tasks Done:

  • Router configuration
  • DNS1 = 192.168.1.100 / DNS2 = 8.8.8.8
  • Install Raspbian Lite
sudo apt-get update && sudo apt-get upgrade -y
  • Configure a management and service static IP addresses in the /etc/dhcpcd.conf file
interface eth0
static ip_address=192.168.42.42/24
interface wlan0
static ip_address=192.168.1.42/24
static routers=192.168.1.1
static domain_name_servers=8.8.8.8
  • Current configuration
Node Name Management IP Service IP
node0 192.168.42.42 192.168.1.42
node1 192.168.42.43 192.168.1.43
node2 192.168.42.44 192.168.1.44
  • Set hostnames, change pi user password, set wifi SSID and enable SSH
raspi-config
  • Disable password login
ssh-keygen
ssh-copy-id pi@192.168.1.xx
  • Enable container features add the following to the end of the file /boot/cmdline.txt
cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory
  • Set local DNS resolution in /etc/hosts
192.168.1.42	node0
192.168.1.43	node1
192.168.1.44	node2
  • NFS Storage
  • Find the disks name in the PI node0
fdisk -l
  • Create the mirror raid in the PI node0
mdadm --create --verbose /dev/md0 --level=mirror --raid-devices=2 /dev/sda1 /dev/sdb1
  • Check the raid status and run a config backup in the PI node0
cat /proc/mdstat
mdadm --detail /dev/md0
mdadm --readwrite /dev/md0
mdadm --detail --scan | sudo tee -a /etc/mdadm/mdadm.conf

cat /etc/mdadm/mdadm.conf
ARRAY /dev/md/0 metadata=1.2 name=node0:0 UUID=8d257fb4:26471052:6f05906b:3beff53f
  • Create the partitions in the PI node0
mkfs -t ntfs --fast /dev/md0
mkfs -t ntfs --fast /dev/sdc1
  • Automatically mount the disk on the boot process in the PI node0
blkid
/dev/md0: UUID="09719E230BFFEE00" TYPE="ntfs" PTTYPE="dos"
/dev/sdc1: UUID="5C36A84D6703C10E" TYPE="ntfs" PTTYPE="dos" PARTUUID="a6cd6b56-01"

vi /etc/fstab

UUID=5C36A84D6703C10E /mnt/raid0/ ntfs defaults,noatime,nofail 0 1
  • Mount and check in the PI node0
mkdir /mnt/raid0
mkdir /mnt/raid1
mount -a

df -Th
...
/dev/md0       fuseblk   7.7G   44M  7.6G   1% /mnt/raid1
/dev/sdc1      fuseblk   466G   84M  466G   1% /mnt/raid0

  • Configure the NFS Server in the PI node0
apt-get install nfs-kernel-server -y

vi /etc/exports
/mnt/raid0 *(rw,no_root_squash,insecure,async,no_subtree_check,anonuid=1000,anongid=1000)
/mnt/raid1 *(rw,no_root_squash,insecure,async,no_subtree_check,anonuid=1000,anongid=1000)

exportfs -ra
  • Configure the NFS Client in the PI node1 and node2
apt-get install nfs-common -y

mkdir /mnt/raid0
mkdir /mnt/raid1

vi /etc/fstab
