This role install consul-template and configure a service to automate renewal of TLS certificates for Hashicorp Vault on **debian-based** distributions.
Available variables are listed below, along with default values. A sample file for the default values is available in `default/renew_vault_certificates.yml.sample` in case you need it for any `group_vars` or `host_vars` configuration.
This variable defines where the files for the role are stored (consul-template configuration + templates).
```yaml
renew_vault_certificates_vault_user: vault # by default, set to vault
```
This variable defines the user that'll be running the certificate renewal service. Defaults to `vault`, and should be present on the host prior to playing this role (ideally when installing vault).
```yaml
renew_vault_certificates_vault_group: vault # by default, set to vault
```
This variable defines the group that'll be running the certificate renewal service. Defaults to `vault`, and should be present on the host prior to playing this role (ideally when installing vault).
```yaml
renew_vault_certificates_vault_addr: https://127.0.0.1:8200 # by default, set to https://127.0.0.1:8200
```
This variable defines the address the consul-template service will query to get the new certificates. Defaults to localhost, but can be changed if vault isnt reachable on localhost (because of missing certificates SANs for example).
```yaml
renew_vault_certificates_vault_token: mysupersecretvaulttokenthatyoushouldchange # by default, set to a dummy string
```
This variable defines the vault token top use to access vault and renew the certificate. Default is a dummy string to pass unit tests.
```yaml
renew_vault_certificates_vault_token_unwrap: false # by default, set to false
```
Defines whether or not the token is wrapped and should be unwrapped (this is an enterprise-only feature of vault at the moment).
```yaml
renew_vault_certificates_vault_token_renew: true # by default, set to true
```
This variable defines whether or not to renew the vault token. It should probably be `true`, and you should have a periodic token to handle this.
```yaml
renew_vault_certificates_cert_dest: /opt/vault/tls/cert.pem # by default, set to /opt/vault/tls/cert.pem
```
This variable defines where to copy the certificates upon renewal. Default to `/opt/vault/tls/cert.pem` but should be changed depending on where you store the certificates.
```yaml
renew_vault_certificates_key_dest: /opt/vault/tls/key.pem # by default, set to /opt/vault/tls/cert.pem
```
This variable defines where to copy the private keys upon renewal. Default to `/opt/vault/tls/key.pem` but should be changed depending on where you store the keys.
```yaml
renew_vault_certificates_info: # by default, set to:
This variable defines the path on vault to retrieve the certificates, as well as the common name and TTL to use for it. It can also include vault aliases in case you have registered vault services in a consul cluster (`active.vault.service.consul,` `standby.vault.service.consul`, `vault.service.consul`).
```yaml
renew_vault_certificates_consul_service_name: vault.service.consul # by default, set to vault.service.consul
```
This variable defines the vault service name in consul. Default is `vault.service.consul`
```yaml
renew_vault_certificates_start_service: false
```
This variable defines whether or not to start the service after creating it. By default, it is only enabled, but not started, in case you're building golden images (in which case you probably don't want a certificate generated during the build process).
This role has a task that installs its own dependencies located in `task/prerequisites.yml`, so that you don't need to manage them. This role requires both `ednxzu.manage_repositories` and `ednxzu.manage_apt_packages` to install consul-template.
