Terraform files for creating a Ceph cluster on OTC with oneprovider supporting a space

Configuring

In order to build your Ceph cluster you need to:

• run ssh-agent and add your key. It will further be used to login into the created VMs.
• provide your openstack credentials by editting parameter.tvars. The username should be the same as shown in the OTC console. You can not use the email or mobile number, which can also be used to login to the OTC web console.
• eventually change values in varaibles.tf according to the comments in this file.

In order to configure oneprovider and oneclient you need to:

• have a registered Internet domain which uses (delegates to) the following nameservers:
  • ns1.open-telekom-cloud.com.
  • ns2.open-telekom-cloud.com.
• have a support token from your onezone
• have an access token from your onezone

Edit variables.tf and set at least the following vars:

• dnszone - your registered Internet domain
• email - your email
• onezone - onezone URL
• support_token - request space support token
• access_token - access token
• project - project name. It is used to prefix VM names. It should be unique among OTC as it is used to create names of VMs. The provider will have the following FQDN: ${project}-op-01.${dnszone} publicly accessible.

The variables can also be provided interactively or set as command line args. For example:

terraform apply -var project=example_project -var [email protected] ....

Running

Build your Ceph cluster issuing:

terraform init
terraform apply -var-file parameter.tvars

The oneprovider credentials are displayed in green somewhere in the ugly output of terraform/ansible. The same output is stored in ~/onedatify.stdout on the oneprovider node.

Accessing your Ceph cluster

After a successful built the public IP of the cluster management node is displayed. Use it to login:

ssh -A ubuntu@THE_IP

Check that Ceph is running:

sudo ceph -s

Example command flow

eval `ssh-agent`
ssh-key
git clone https://github.com/darnik22/ceph-tf.git
cd ceph-tf
vi parameter.tvars
vi variables.tf
terraform init
terraform apply -var-file parameter.tvars
ssh -A ubuntu@THE_IP_OF_MGT_NODE
sudo ceph -s
ssh ${project}-client-01
cd onedata/YOUR_SPACE
ls
