Amtool allows a config file to specify some options for convenience. The default config file paths are `$HOME/.config/amtool/config.yml` or `/etc/amtool/config.yml`
An example configfile might look like the following:
```
# Define the path that amtool can find your `alertmanager` instance at
alertmanager.url: "http://localhost:9093"

To create a highly available cluster of the Alertmanager the instances need to
be configured to communicate with each other. This is configured using the
`-mesh.*` flags.
`--cluster.*` flags.
- `--mesh.peer-id` string: mesh peer ID (default "<hardware-mac-address>")
- `--mesh.listen-address` string: mesh listen address (default "0.0.0.0:6783")
- `--mesh.nickname` string: mesh peer nickname (default "<machine-hostname>")
- `--mesh.peer` value: initial peers (repeat flag for each additional peer)
- `--cluster.listen-address` string: cluster listen address (default "0.0.0.0:9094")
- `--cluster.advertise-address` string: cluster advertise address
- `--cluster.peer` value: initial peers (repeat flag for each additional peer)
- `--cluster.peer-timeout` value: peer timeout period (default "15s")
- `--cluster.gossip-interval` value: cluster message propagation speed
(default "200ms")
- `--cluster.pushpull-interval` value: lower values will increase
convergence speeds at expense of bandwidth (default "1m0s")
- `--cluster.settle-timeout` value: maximum time to wait for cluster
connections to settle before evaluating notifications.
The `mesh.peer-id` flag is used as a unique ID among the peers. It defaults to
the MAC address, therefore the default value should typically be a good option.
The same applies to the default of the `mesh.nickname` flag, as it defaults to
the hostname.
The chosen port in the `mesh.listen-address` flag is the port that needs to be
specified in the `mesh.peer` flag of the other peers.
The chosen port in the `cluster.listen-address` flag is the port that needs to be
specified in the `cluster.peer` flag of the other peers.
To start a cluster of three peers on your local machine use `goreman` and the
Procfile within this repository.
