 # triton-moirai
+
+This repository is part of the Triton Data Center project. See the [contribution
+guidelines](https://github.com/TritonDataCenter/triton/blob/master/CONTRIBUTING.md)
+and general documentation at the main
+[Triton project](https://github.com/TritonDataCenter/triton) page.
+
+Moirai is an HAProxy based load balancer for Triton.
+
+## Features
+
+* Automatic certificate generation via [triton-dehydrated][1]
+* Automatic configuration of backends
+
+[1]: https://github.com/TritonDataCenter/triton-dehydrated
+
+## Backend configuration
+
+Moirai supports the following keys:
+
+* `cloud.tritoncompute:loadbalancer` - This must be set to `true` and will be
+   used by node-triton and/or CloudAPI at a later date.
+* `cloud.tritoncompute:portmap` - This configures the listening ports to
+  backend mappings. This is comma separated list of service designations.
+  See below for service designation syntax.
+* `cloud.tritoncompute:max_rs` - By default up to 32 backend servers are
+  supported. If you need to scale larger than 32 backend instances, set this
+  to the desired value.
+* `cloud.tritoncompute:certificate_name` - Comma separated list of certificate
+  subjects. The first in the list will be the subject `CN`. The rest of the
+  names will be Subject Alternate Names (SAN).
+
+Metadata keys can be added post-provision. The load balancer will reconfigure
+itself shortly after the metadata is updated.
+
+All other metadata keys used by Triton are also supported (e.g.,
+`triton.cns.services`, `tritoncli.ssh.proxy`, etc.).
+
+## Service Designations
+
+The `cloud.tritoncompute:portmap` metadata key is a list of service designations
+separated by commas or spaces.
+
+A service designation uses the following syntax:
+
+    <type>://<listen port>:<backend name>[:<backend port>]
+
+* `type` - Must be one of `http`, `https`, or `tcp`.
+  * `http` - Configures a Layer-7 proxy using the HTTP protocol. The backend
+    server(s) must not use SSL/TLS. `X-Forwarded-For` header will be added to
+    requests.
+  * `https` - Configures a Layer-7 proxy using the HTTP protocol. The backend
+    server(s) must use SSL/TLS. The backend certficate will not be verified. The
+    front end services will use a certificate issued by Let's Encrypt if
+    the `cloud.tritoncompute:certificate_name` metadata key is also provided.
+    Otherwise, a self-signed certificate will be generated. `X-Forwarded-For`
+    header will be added to requests.
+  * `tcp` - Configures a Layer-4 proxy. The backend can use any port. If SSL/TLS
+    is desired, the backend must configure its own certificate.
+* `listen port` - This designates the front end listening port.
+* `backend name` - This is a DNS name that must be resolvable. This **SHOULD**
+  be a CNS name, but can be any fully qualified DNS domain name.
+* `backend port` - Optional. This designates the back end port that servers will
+  be listening on. If provided, the back end will be configured to use A record
+  lookups. If a not provided then the back end will be configured to use SRV
+  record lookup.
+
+Examples:
+
+    http://80:my-backend.svc.my-login.us-west-1.cns.example.com:80
+    https://443:my-backend.svc.my-login.us-west-1.cns.example.com:8443
+    tcp://636:my-backend.svc.my-login.us-west-1.cns.example.com
+
+## Certificate setup
+
+In order to properly generate a certificate you must have DNS CNAME records
+pointing to the load balancer instance's CNS records. See the
+[`triton-dehydrated`][2] documentation for how to properly configure this.
+
+[2]: https://github.com/TritonDataCenter/triton-dehydrated?tab=readme-ov-file#how-to-use-inside-a-user-container-on-triton
+
+## Development
+
+Typically development is done by:
+
+* making edits to a clone of triton-moirai.git on a Mac (likely Linux too, but
+  that's untested) or a SmartOS development zone,
+
+        git clone [email protected]:TritonDataCenter/triton-moirai.git
+        cd triton-moirai
+        git submodule update --init   # not necessary first time
+        vi
+
+* building:
+
+        make all
+        make check
+
+* then testing changes.
+
+## Notes
+
+* Once a named certificate is used, the load balancer instance can't go back to
+  a self-signed certificate. Continue to use the expired certificate or
+  deploy a replacement loadbalancer.
+
+## Testing
+
+* Prerequisites:
+  * Set up fabrics on the Triton deployment.
+  * Ensure there are no existing NAT zones provisioned.
+  * Execute `sdcadm post-setup dev-headnode-prov`.
+
+* To sync local changes to a running COAL and run the test suite there use:
+
+    make test-coal
+
+* To run tests while logged into a running VMAPI instance:
+
+    /opt/smartdc/vmapi/test/runtests
