Deploy 3-node ceph cluster in HETZNER-CLOUD

Hi.
With this repo I learn how to use Terraform on Hetzner-Cloud
and deploy a ceph 3-Node cluster with bash script's

terraform and bash scripts 
are deployed with python3 to the VM's

Processes are: ceph-mon, ceph-osd, ceph-mgr, ceph-crush

problems: processes mon,osd,mgr does not start or exit fast witout any error messages
solution: chmod,chown of keyring in /var/lib/ceph/[mon,osd,mgr]/keyring

first deploy VM's with terraform

# cd into terraform subdir hz or hz-min
cd hz

# set hcloud_token , terraform.tfvars (option)

terraform init # one time

# create ssh-keys and deploy terraform
python3 deploy.py
cd ..

second deploy bash-scripts to VM's

python3 deploy-ceph.py

# check ceph-cluster
python3 terra-ssh.py 'ceph -s' # timeout ?
python3 terra-ssh 'ceph/run-ps.sh'

Explain

• deploy the node's

python3 deploy.py

• subdir ceph/run-* -> ssh -> vm
• apt install ceph
• generate CEPH config+key in first-vm
• copy config from first node to other nodes
• run ceph-mon@$node

check the nodes with

python3 terra-ssh.py 'md5sum /tmp/*'
python3 terra-ssh.py 'source ./host.conf; echo $node'
python3 terra-ssh 'ceph/run-ps.sh'
python3 terra-ssh.py 'ceph -s' # timeout ?
