# Deploying a Nomad cluster
|
|
|
|
This documentation explains each steps necessary to successfully deploy a Nomad cluster using the ednz_cloud.hashistack ansible collection.
|
|
|
|
## Prerequisites
|
|
|
|
You should, before attempting any deployment, have read through the [Quick Start Guide](./quick_start.md). These steps are necessary in order to ensure smooth operations going forward.
|
|
|
|
## Variables
|
|
|
|
### Basics
|
|
|
|
First, in order to deploy a nomad cluster, you need to enable it.
|
|
|
|
```yaml
|
|
enable_nomad: "yes"
|
|
```
|
|
|
|
Selecting the nomad version to install is done with the `nomad_version` variable.
|
|
|
|
```yaml
|
|
nomad_version: latest
|
|
```
|
|
|
|
The vault version can either be `latest` or `X.Y.Z`.
|
|
|
|
For production deployment, it is recommended to use the `X.Y.Z` syntax.
|
|
|
|
### General settings
|
|
|
|
First, you can change some general settings for nomad, like the dc and region options.
|
|
|
|
```yaml
|
|
nomad_datacenter: dc1
|
|
nomad_region: global
|
|
```
|
|
|
|
### ACLs settings
|
|
|
|
By default, ACLs are enabled on nomad, and automatically bootstrapped.
|
|
You can change this by editing the `nomad_acl_configuration` variable:
|
|
|
|
```yaml
|
|
nomad_acl_configuration:
|
|
enabled: true
|
|
token_ttl: 30s
|
|
policy_ttl: 60s
|
|
role_ttl: 60s
|
|
```
|
|
|
|
### Consul integration settings
|
|
|
|
By default, if consul if also enabled, nomad will use it to register itself as a consul service and also use consul to automatically join the cluster.
|
|
|
|
```yaml
|
|
nomad_enable_consul_integration: "{{ enable_consul | bool }}"
|
|
nomad_consul_integration_configuration:
|
|
address: "127.0.0.1:{{ hashicorp_consul_configuration.ports.https if consul_enable_tls else hashicorp_consul_configuration.ports.http }}"
|
|
auto_advertise: true
|
|
ssl: "{{ consul_enable_tls | bool }}"
|
|
token: "{{ _credentials.consul.tokens.nomad.server.secret_id if nomad_enable_server else _credentials.consul.tokens.nomad.client.secret_id}}"
|
|
tags: []
|
|
```
|
|
|
|
Optionally, you can add tags to you nomad services, or disable the consul integration if you don't plan on using it.
|
|
|
|
### Vault integration settings
|
|
|
|
Vault integration for nomad is by default disabled, as it requires some vault configuration that is out of the scope of this collection.
|
|
|
|
You can, once you have deployed and configured vault (or if you are using an external vault not managed by the collection), enable the integration
|
|
|
|
```yaml
|
|
nomad_enable_vault_integration: false
|
|
nomad_vault_integration_configuration: {}
|
|
```
|
|
|
|
For configuration options, please refer to the [Official Documentation](https://developer.hashicorp.com/nomad/docs/configuration/vault)
