+The following arguments must be provided in addition to the arguments provided in ![on-premise agent](README.md). You can configure multiple bitbuckets by including multiple entries with different indices. The private key of each index must match up with the host for that index.

+* `moderne_agent_bitbucket[{index}]_host` - fully-qualified hostname of running bucketbucket instance. example: `bitbucket.org`
