Open Telekom Cloud (OTC) is a public cloud service based on OpenStack powered by Deutsche Telekom. [1]
Sometimes people ask: is it OpenStack? Or not? The answer is: Of course,yes. No. Maybe. I'm afraid.
One thing is certain: #OTC #RunsOnOpenstack
Technology is provided by Huawei, one of the Top 4 contributor in OpenStack [2]. So you have core technology with slightly different services in OTC. Now there are different ways to connect to the cloud:
1. The openstack client
Doing a
Shell
apt-get -y install curl git ansible python-openstackclient |
to install. Further there is a standard way to store configuraton data: os-client-config [3] Doing some shell commands:
Shell
mkdir -p ~/.config/openstack | |
touch ~/.config/openstack/clouds.yml | |
chmod 600 ~/.config/openstack/clouds.yml | |
vi ~/.config/openstack/clouds.yml |
clouds.yml
Shell
clouds: | |
otc.10000: | |
auth: | |
auth_url: https://iam.eu-de.otc.t-systems.com:443/v3 | |
username: xxxxxx | |
password: xxxxxx | |
project_name: eu-de | |
project_domain_name: Default | |
user_domain_name: OTC-EU-DE-00000000001000010000 | |
region_name: eu-de | |
otc.19720: | |
auth: | |
auth_url: https://iam.eu-de.otc.t-systems.com:443/v3 | |
username: xxxxx | |
password: xxxxx | |
project_name: eu-de | |
project_domain_name: Default | |
user_domain_name: OTC-EU-DE-00000000001000019720 | |
region_name: eu-de |
For multiple mandants are multiple chapter. Configure username, password and user_domain_name.
Test:
Shell
openstack --os-cloud otc.19720 server list |
2. Python OTC-Client
The tool is similar built like the openstack client. From the feeling you have the same usage. Installation:
Shell
apt-get -y install python-pip | |
pip install python-otcclient |
And configuration:
Shell
mkdir -p ~/.otc | |
touch ~/.otc/config | |
chmod 600 ~/.otc/config | |
vi ~/.otc/config |
config
Shell
[otc] | |
# otc_access_key_id = yyyyy | |
# otc_secret_access_key = yyyyy | |
username = xxxxx | |
apikey = xxxxx | |
domain = OTC-EU-DE-00000000001000019720 |
apikey means here password. There were some changes in the authorization in the past.
Test
Shell
otc ecs describe_instances |
3. Bash OTC-Tools
This was the first developement of a cli tool for OTC and it's still supported. OpenStack environment variables are used but the usage of the tool is very different.
Installation:
Shell
apt-get -y install curl git libs3-2 jq | |
git clone https://github.com/OpenTelekomCloud/otc-tools.git | |
touch ~/.otc_env.sh | |
chmod 600 ~/.otc_env.sh | |
vi ~/.otc_env.sh |
otc_env.sh
Shell
OS_USERNAME=xxxxx | |
OS_PASSWORD=xxxxx | |
OS_USER_DOMAIN_NAME=OTC-EU-DE-00000000001000019720 | |
OS_PROJECT_NAME=eu-de | |
OS_AUTH_URL=https://iam.eu-de.otc.t-systems.com/v3 |
Test connection:
Shell
cd otc-tools | |
./otc.sh ecs list | |
cd ~ |
4. Ansible for Open Telekom Cloud
Ansible is more an tool for automation things or machine to machine connection. But also operator can run task on OTC.
Installation:
Shell
add-apt-repository -y ppa:ansible/ansible | |
apt-get update | |
apt-get -y install curl git ansible python-jmespath python-netaddr libs3-2 | |
git clone https://github.com/eumel8/ansible-otc.git | |
cd ansible-otc | |
cp secrets.yml _secrets.yml | |
cp ecs_secrets.yml _ecs_secrets.yml | |
cp elb_secrets.yml _elb_secrets.yml | |
ansible-vault edit _secrets.yml --vault-password-file vaultpass.txt |
Configuration:
Shell
USERNAME: "xxxxx" | |
PASSWORD: "xxxxx" | |
DOMAIN: "OTC-EU-DE-00000000001000019720" |
Test connection
Shell
ansible-playbook -i hosts ecs.yml --vault-password-file vaultpass.txt |
