When deploying to large numbers of hosts, you might prefer not to restart your services on every host at the same time.
MRSK's default is to boot new containers on all hosts in parallel. But you can control this by configuring `group_limit` and `group_wait` as boot options:
MRSK's default is to boot new containers on all hosts in parallel. But you can control this by configuring `boot/limit` and `boot/wait` as options:
```yaml
service: myservice
boot:
group_limit: 10 # Can also specify as a percentage of total hosts, such as "25%"
group_wait: 2
limit: 10 # Can also specify as a percentage of total hosts, such as "25%"
wait: 2
```
When `group_limit` is specified, containers will be booted on, at most, `group_limit` hosts at once. MRSK will pause for `group_wait` seconds between batches.
When `limit` is specified, containers will be booted on, at most, `limit` hosts at once. MRSK will pause for `wait` seconds between batches.
These settings only apply when booting containers (using `mrsk deploy`, or `mrsk app boot`). For other commands, MRSK continues to run commands in parallel across all hosts.
