| MK | 2 | |
| 3 | A simple deplyoment creating a bastion host and two worker nodes. It can't get simpler ... | |
| 4 | ||
| 5 | ### Environment variables | |
| 6 | ||
| 7 | Deployment is controlled by two configuration files: | |
| 8 | ||
| 9 | * env_vars.yml | |
| 10 | * sample_vars.yml | |
| 11 | ||
| 12 | `env_vars.yml` defines all configuration parameters that COULD be modified, whereas `sample_vars.yml` is a *template* for all environment specific values that HAVE to be changed. | |
| 13 | ||
| 14 | Start by creating a copy of `sample_vars.yml` and rename it (e.g. `my_sample_vars.yml`). Then modifiy all parameters to match your environment. | |
| 15 | ||
| 16 | #### Secrets | |
| 17 | ||
| 18 | Some deployments need **secrets** e.g. your AWS credentials or API tokens. | |
| 19 | ||
| 20 | DO NOT add these to git ! | |
| 21 | ||
| 22 | Instead create a file called e.g. `./ansible/my_secret_vars.yml` and store all secrets etc. there. This file can also be reused for other deplyoments. | |
| 23 | ||
| 24 | NOTE: | |
| 25 | ||
| 26 | Both `my_sample_vars.yml` `my_secret.vars.yml` are in the `.gitignore` configuration which SHOULD protect you from adding them to git! | |
| 27 | ||
| 28 | ### Run the Ansible playbooks | |
| 29 | ||
| 30 | Run follwoing commands from the `./ansible` folder: | |
| 31 | ||
| 32 | #### Install | |
| 33 | ||
| 34 | ```shell | |
| 35 | ansible-playbook main.yml -e @configs/simple-example/my_sample_vars.yml -e @my_secret_vars.yml | |
| 36 | ``` | |
| 37 | ||
| 38 | #### Uninstall | |
| 39 | ||
| 40 | ```shell | |
| 41 | ansible-playbook destroy.yml -e @configs/simple-example/my_sample_vars.yml -e @my_secret_vars.yml | |
| 42 | ``` | |
