plane.watch Border Control

How plane.watch receives data from feeders.

Designed to be horizontally scalable, sat behind TCP load balancer(s).

plane.watch Border Control

Overview

Terminates incoming stunnel'd BEAST and MLAT connections from feeders
- bordercontrol expects the SSL SNI sent from the client to be the feeder's "API key" (a UUID)
- SNIs in incoming connections are checked against a list of valid UUIDs pulled from ATC.
- Connections with invalid SNIs are rejected.
Builds and starts regional MLAT servers (muxes)
Builds and manages "feed-in" container image
When feeders connect:
- A "feed-in" container is automatically created and started for the specific feeder, which:
  - Runs pw_ingest which receives and decodes BEAST and puts the position data into NATS
- BEAST data is sent to the "feed-in" container
- MLAT connections are proxied to mlat-server instances

Configuring the environment

In the root of the repository, create a .env file containing the following:

Environment Variable	CLI Flag Equiv.	R/O	Description	Example
`ATC_UPDATE_FREQ`	`--atcupdatefreq`	O	Frequency (in minutes) for valid feeder updates from ATC	1
`ATC_URL`	`--atcurl`	R	URL to ATC API	`http://10.0.6.2:3000`

`BC_VERBOSE`	`--verbose`	O	Change default log level from Info to Debug
`FEED_IN_BUILD_CONTEXT`	`--feedinimagecontext`	O	Feed-in-image build context	`/opt/feed-in/`
`FEED_IN_BUILD_DOCKERFILE`	`--feedinimagedockerfile`	O	Feed-in image build Dockerfile (relative to context)	`Dockerfile.feeder`
`FEED_IN_CONTAINER_PREFIX`	`--feedincontainerprefix`	O	Feed-in container prefix	`feed-in-`
`FEED_IN_CONTAINER_NETWORK`	`--feedincontainernetwork`	O	Feed-in container network	`bordercontrol_feeder`

`PW_INGEST_SINK`	`--pwingestpublish`	R	URL passed through to `pw_ingest` in feed-in containers	`nats://nats-ingest.plane.watch:4222`
`NATS`	`--natsurl`	O	NATS URL for stats/control	`nats://nats-ingest.plane.watch:4222`
`NATS_INSTANCE`	`--natsinstance`	O	NATS instance identifier for this instance of Bordercontrol	`prod-bordercontrol-01`

Note: O = Optional, R = Required.

Example:

# ATC API connection details
ATC_URL=http://atc.yourdomain.tld:3000
ATC_USER=REDACTED
ATC_PASS=REDACTED
# SSL Key/Cert
BC_CERT_FILE=/path/to/fullchain.pem
BC_KEY_FILE=/path/to/privkey.pem
# pw_ingest
PW_INGEST_SINK=nats://nats-ingest.youdomain.tld:4222
NATS=nats://nats-ingest.youdomain.tld:4222

Create a the docker-compose-local.yml file (see the example), under services: -> bordercontrol:, ensure the path holding SSL certs/keys is mapped as a volume.

Operation

Starting the environment

From the root of the repository, run docker compose up -d --build.

This will build the images, containers and launch bordercontrol.

Stopping the environment

From the root of the repository, run docker compose down.

This will stop and remove multiplexer and bordercontrol containers. After approximately 10 minutes, the feed-in containers will stop and be removed.

Rebuilding the environment

From the root of the repository, run docker compose build --pull && docker compose up -d.

Any updated containers will be rebuilt and recreated.

Updating just feed-in containers

This can be done via rebuilding the feed-in-builder container, or a NATS request to pw_bordercontrol.feedinimage.rebuild with the body containing the NATS instance or wildcard (*) for all instances:

From the root of the repository, run: docker compose build --pull feed-in-builder; or
via NATS: nats req --timeout=2m pw_bordercontrol.feedinimage.rebuild "*"

For the feed-in containers, bordercontrol checks these every 5 minutes. Containers are updated one at a time. After updating a container, bordercontrol waits 30 seconds, to hopefully prevent any visible impact on the web UI. These timeouts/sleeps can be skipped by sending a SIGUSR1 signal to bordercontrol. This is shown in the logs:

Mon Nov  6 20:51:43 UTC 2023 INF caught signal, proceeding immediately goroutine=checkFeederContainers signal="user defined signal 1"
Mon Nov  6 20:51:43 UTC 2023 INF out of date container being killed for recreation container=feed-in-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx goroutine=checkFeederContainers

Re-reading SSL certificates

Bordercontrol will non-disruptively re-read SSL certificate(s) if it receives a SIGHUP, or a NATS request to pw_bordercontrol.stunnel.reloadcertkey with the body containing the NATS instance or wildcard (*) for all instances.

via SIGHUP: docker exec bordercontrol pkill -HUP bordercontrol
via NATS: nats req pw_bordercontrol.stunnel.reloadcertkey "*"

Kicking a Feeder

If the need arises to kick a feeder, this can be done via NATS:

Subject	Header	Body	Description
`pw_bordercontrol.feeder.kick`	Ignored	Feeder API Key	Immediately removes the feed-in container associated with the feeder.

Example:

# nats req pw_bordercontrol.feeder.kick <Feeder API Key>
13:33:35 Sending request on "pw_bordercontrol.feeder.kick"
13:33:35 Received with rtt 254.043895ms
+ACK

Feed-In Container Health

Healthchecks are run within the feed-in containers.

The healthcheck will check the following:

Checks BEAST connection inbound from bordercontrol
Checks NATS connection outbound

If any of the above checks fail, the container is marked as unhealthy.

If the feed-in container has been unhealthy for longer than 10 minutes, the container will terminate.

As the containers are launched via bordercontrol with "autoremove" enabled, the stopped container will be removed automatically.

This ensures that only containers of active feeders are started and running.

Statistics

NATS

Bordercontrol will report statistics via NATS.

On all replies, the bordercontrol instance is returned as a header, so the instance the feeder is connected to can be identified if needed.

Per-feeder

Subject	Header	Body	Description
`pw_bordercontrol.feeder.connected.beast`	Ignored	Feeder API Key	Returns `true` if feeder matching API Key has a BEAST protocol connection.
`pw_bordercontrol.feeder.connected.mlat`	Ignored	Feeder API Key	Returns `true` if feeder matching API Key has a MLAT protocol connection.
`pw_bordercontrol.feeder.metrics`	Ignored	Feeder API Key	Returns JSON containing metrics for all connections. Eg: `{"feeder_code":"YPPH-0003","label":"Bayswater2","beast_connected":true,"beast_bytes_in":10120,"beast_bytes_out":0,"beast_connection_time":"2024-01-04T15:14:03.892056108Z","mlat_connected":true,"mlat_bytes_in":140,"mlat_bytes_out":458,"mlat_connection_time":"2024-01-04T15:13:44.397506876Z"}`
`pw_bordercontrol.feeder.metrics.beast`	Ignored	Feeder API Key	Returns JSON containing metrics for BEAST connection. Eg: `{"bytes_in":305177,"bytes_out":0,"connection_time":"2024-01-04T14:37:47.87329718Z"}`
`pw_bordercontrol.feeder.metrics.mlat`	Ignored	Feeder API Key	Returns JSON containing metrics for MLAT connection. Eg: `{"bytes_in":29172,"bytes_out":744,"connection_time":"2024-01-04T14:37:27.133693249Z"}`

If the requested feeder is not connected to bordercontrol, bordercontrol will silently ignore the message. This ensures that in scale-out environments, you can simply use the first (and hopefully only) reply. It is suggested to use a short timeout too (100ms should be plenty).

All Feeders

Subject	Header	Body	Description
`pw_bordercontrol.feeders.metrics`	Ignored	Ignored	Returns JSON containing metrics for all feeders, all connections. Eg: `{"<feeder api key redacted>":{"feeder_code":"YPPH-0003","label":"Bayswater2","beast_connected":true,"beast_bytes_in":258,"beast_bytes_out":0,"beast_connection_time":"2024-01-04T15:28:28.697372348Z","mlat_connected":true,"mlat_bytes_in":140,"mlat_bytes_out":458,"mlat_connection_time":"2024-01-04T15:28:10.295874658Z"}}`

Human Readable

Bordercontrol will display a simple HTML table of feeders with statistics at http://dockerhost:8080

API

Bordercontrol supports the following API calls to http://dockerhost:8080:

Query Type	URL Path	Returns
`GET`	`/api/v1/feeder/<UUID>`	Statistics for single feeder by UUID
`GET`	`/api/v1/feeders/`	Statistics for all feeders

These queries return a JSON object with keys Data and Error. If Error == "", then the Data key should contain the requested data. If Error != "", then the error details are contained within Error and any data in Data should be discarded.

Prometheus Metrics

Prometheus metrics are published at http://dockerhost:8080/metrics.

NATS Detail

`pw_bordercontrol.ping`
