# terraform
|
|
|
|
The terraform code for my small personal infrastructure.
|
|
|
|
## Resources
|
|
|
|
Currently, this will provision:
|
|
* DNS entries on Namecheap
|
|
* Alpine VPS on Linode
|
|
* OpenBSD VPS on Vultr
|
|
|
|
## Bootstrapping
|
|
|
|
This repo alone wouldn't be able to bootstrap all of its resources by itself.
|
|
If I had to start again from scratch I'd need to bootstrap some things
|
|
manually.
|
|
|
|
For instance, I use `caladan` as an http(s) proxy when applying the plans,
|
|
because `caladan` has a static IP that I can whitelist one Namecheap's and
|
|
Vultr's APIs.
|
|
My home internet does not have a static IP.
|
|
So I can't really apply the infrastructure in this repo before `caladan` is
|
|
already provisioned and configured.
|
|
|
|
So, this repo is mostly as documentation for myself and most of the time I
|
|
create resources manually and import them later to terraform.
|
|
|
|
## Wrapper scripts
|
|
|
|
I run Terrafrom through two wrapper scripts: `scripts/init.sh` and
|
|
`scripts/run_terraform`.
|
|
|
|
`scripts/init.sh` is used just to run `terraform init`. It fetches the
|
|
PostgreSQL password (from `pass`) and it passes the connection string manually
|
|
to the partially-configured pg backend.
|
|
|
|
`scripts/run_terraform` is used to run other terraform commands. It sets up the
|
|
`HTTP_PROXY` and `HTTPS_PROXY` variables to use `caladan` as a proxy. It also
|
|
fetches the secrets (from `pass`) and exports the variables for api keys and
|
|
tokens needed by the different providers.
|
|
|
|
Additionally, I also wrote a simple `Makefile` to init/plan/apply quickly.
|
|
|
|
## Backend
|
|
|
|
I use the pg backend on a PostgreSQL hosted on my NAS.
|
|
|
|
### Initializing the backend (only the first time)
|
|
|
|
Create the user (named `terraform`) and database (`terraform_backend`). The
|
|
user's password is managed with `pass`.
|
|
|
|
```sh
|
|
pass generate pg.monotremata.xyz/terraform
|
|
psql --host pg.monotremata.xyz
|
|
```
|
|
|
|
```sql
|
|
CREATE USER terraform WITH ENCRYPTED PASSWORD '****';
|
|
|
|
CREATE DATABASE terraform_backend;
|
|
GRANT ALL PRIVILEGES ON DATABASE terraform_backend TO terraform;
|
|
|
|
CREATE DATABASE terraform_lan;
|
|
GRANT ALL PRIVILEGES ON DATABASE terraform_lan TO terraform;
|
|
```
