It performs the following actions: 4 | 5 | 1. Create network and subnet 6 | 2. Create router 7 | 3. Create keypair 8 | 4. Create security group 9 | 5. Create VM instance with non-ephemeral disk 10 | 6. Apply cloud config which creates a new user and installs nginx 11 | 7. Assign Floating IP to the instance 12 | 8. Execute bootstrap scrpits during instance provisioning over ssh 13 | 14 | Optionally, you can enable cloud config by uncommenting corresponding line in the main.tf 15 | 16 | 17 | ## File structure 18 | | Name | Description | 19 | |------|-------------| 20 | README.md | This file, obviously 21 | demo_rsa, demo_rsa.pub | SSH keypair, only to be used for this demonstration 22 | terraform.tf | The terraform manifest with all defined resources 23 | variables.tf | Variables that you can change or set default values 24 | terraform-openrc.sh | should be run initially to setup username, tenant and password 25 | terraform.tfstate, terraform.tfstate.backup | tfstate and tfstate.backup so that terraform can keep track on changes 26 | 27 | 28 | ## How to use 29 | 30 | 1. Make sure you have installed [Terraform](https://www.terraform.io/) 31 | 2. Get your OpenStack API credentials by requesting them at [https://help.mail.ru/mcs/support]()https://help.mail.ru/mcs/support) 32 | 3. Run the terraform-openrc.sh script. It will ask about username, tenant and password. 33 | 4. Then run "terraform plan". If that fails, make sure you've used the correct credentials (run terraform-openrc.sh again) 34 | 5. Last, run "terraform apply" to install all the infrastructure, described in the terraform.tf 35 | 36 | ```bash 37 | $ ./terraform-openrc.sh 38 | [...] 39 | $ terraform init (if it is the first time you run terraform) 40 | $ terraform plan 41 | $ terraform apply 42 | ``` 43 | 44 | You should now have a fully working environment with everything described in the beginning of this README. 45 |
