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.

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.
|

This variable defines where to copy the certificate authority upon renewal. Default to `/opt/consul/tls/ca.pem` but should be changed depending on where you store the certificate authority.

|
||||
ttl: 90d
|
||||
is_server: false
|
||||
include_consul_service: false
|
||||
```
|
||||
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`).
|
||||
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 consul aliases in case you have registered consul services in itself (`consul.service.consul`). It also handles whether or not to append the server.yourdc.consul SAN, in case you're enforcing hostname checking.
|

|
||||
```yaml
|
||||
renew_vault_certificates_consul_service_name: vault.service.consul # by default, set to vault.service.consul
|
||||
renew_consul_certificates_consul_dc_name: dc1.consul # by default, set to dc1.consul
|
||||
```
|
||||
This variable defines the vault service name in consul. Default is `vault.service.consul`
|
||||
In case you enforce hostname checking, set this variable to your desired dc and consul domain. This is used to forge the SAN that will be checked by consul to only allow specific nodes to be managers.
|
||||
|
||||
```yaml
|
||||
renew_vault_certificates_start_service: false
|
||||
renew_consul_certificates_consul_service_name: consul.service.consul # by default, set to consul.service.consul

This variable defines the consul service name in consul. Default is `consul.service.consul`
|
||||
|
||||
```yaml
|
||||
renew_consul_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).
