-# General IaaS infrastructure demo
-
-Assuming you are added into a group project and you can log in via [MetaCentrum OpenStack cloud dashboard](https://cloud.metacentrum.cz/) using one of supported federations (e-INFRA CZ, EGI CHeck-in, ...).
-
-We recommend to build custom cloud infrastructure with Terraform or openstack client rather than using [MetaCentrum OpenStack cloud Horizon UI dashboard](https://dashboard.cloud.muni.cz).
-
-Below demos show in detail how to do so.
-
-## [Terraform `general` demo](./terraform)
-
-Terraform demo shows how to automate building highly scalable IaaS infrastructure.
-
-## [OpenStack client `general` demo](./commandline)
-
-OpenStack shell script demo shows how to automate small IaaS infrastructure which does not need additional scalability.

openstack-infrastructure-as-code-automation/clouds/g1/brno/general/commandline/README.md

-# Build OpenStack infrastructure from command-line using openstack client
-
-## Pre-requisites
- * Linux/Mac/WSL2 terminal
- * BASH shell
- * installed openstack client ([how?](https://docs.fuga.cloud/how-to-use-the-openstack-cli-tools-on-linux))
- * MetaCentrum OpenStack cloud [group project granted](https://docs.e-infra.cz/compute/openstack/technical-reference/brno-site/get-access/#group-project).
- * downloaded application credentials from OpenStack Horizon dashboard ([how?](https://docs.cloud.muni.cz/cloud/cli/#getting-credentials)) and store as text file `project_openrc.sh.inc`.
-
-## How to use the script
-```sh
-# in bash shell
-source project_openrc.sh.inc
-EXTRA_VOLUME_SIZE_GB=10 ./cmdline-demo.sh basic-infrastructure-1
-```
-See [linked reference execution](./cmdline-demo.sh.log).
-
-## Infrastructure schema
-How does the basic infrastructure looks like?
-* single VM (ubuntu-jammy)
-  * VM firewall opening port 22
-  * VM SSH keypair generated locally and pubkey uploaded to cloud
-  * attached additional volume (size 10GB)
-* private subnet and network
-* router to external internet
-* public floating ip address

-
-This Terraform module creates up to two kind of VMs:
- - public facing small bastion VM
- - private VM farm
-
-Cloud-init add following:
- - Add ssh keys, disable SSH password auth
- - Create partition and filesystemand mount extra data from extra volume
-
-## Infrastructure schema
-
-### Two tier infrastructure: public bastion and private VM farm
-

-
-### Single tier infrastructure: public VM farm

-
-## Create Infrastructure
-
-1. Clone the repository.
-1. Load you OpenStack application credentials to environment variables `source project_openrc.sh.inc`
-1. Override any infrastructure variables in [main.tf](main.tf) file if needed. Full set of variables can be found in [modules/2tier_public_bastion_private_vm_farm/variables.tf](modules/2tier_public_bastion_private_vm_farm/variables.tf) or [modules/1tier-public-vm-farm/variables.tf](modules/1tier-public-vm-farm/variables.tf).
-1. In the [terraform root directory](/clouds/g1/brno/general/terraform) run following commands to initiate and validate environment
-   * `terraform init`
-   * `terraform validate`
-1. In the [same directory](/clouds/g1/brno/general/terraform) run commands to deploy cloud infrastructure
-   * `terraform plan --out plan`
-   * `terraform apply plan`
-1. Once you need to change the infrastructure, first modify the infrastructure declaration and repeat above steps to deploy changes.
-1. Similarly for resource teardown, once you want to clean-up cloud resources issue `terraform destroy`.
-
-
-Detailed terminal transcript can be found in [terminal-transcript.log](./terminal-transcript.log).
-
-
-## Access to the VM nodes
-
-In single tier infrastructure you access directly the individual VM nodes via SSH on public IP addresses.
-Two tier infrastructure requires the access following way:
-1. Establish the connection with bastion
-```sh
-sshuttle -r ubuntu@<bastion-ip>
-```
-1. Connect directly to VM nodes via SSH on private IP addresses:
-```sh
-ssh  ubuntu@<vm-node-ip-from-10.10.10.0/24>
-```
