| `alertmanager_version` | 0.21.0 | Alertmanager package version. Also accepts `latest` as parameter. |
| `alertmanager_binary_local_dir` | "" | Allows to use local packages instead of ones distributed on github. As parameter it takes a directory where `alertmanager` AND `amtool` binaries are stored on host on which ansible is ran. This overrides `alertmanager_version` parameter |

| `alertmanager_checksums_url` | `https://github.com/prometheus/alertmanager/releases/download/v{{ alertmanager_version }}/sha256sums.txt` | URL of the alertmanager checksums file |
| `alertmanager_web_listen_address` | 0.0.0.0:9093 | Address on which alertmanager will be listening |
| `alertmanager_web_external_url` | http://localhost:9093/ | External address on which alertmanager is available. Useful when behind reverse proxy. Ex. example.org/alertmanager |
