APRS Dashboard

Service API to record and query for Automated Position Reporting System (APRS) messages.

Installation

APRS Dashboard is designed to run in a Docker container. Hopefully you've come to know and love the flexibility and ease that comes with using Docker. APRS Dashboard Docker images are available on DockerHub.

APRS messages are stored in a Redis database. The Dynamic Redis fork is used so that geo searches by latitude-longitude can be performed on Redis data. These instructions make use of a Docker image for the Dynamic Redis server.

docker pull urlgrey/dynamic-redis
docker pull urlgrey/aprs-dashboard

# Run Redis container
sudo docker run --name aprs_db -d -p 6379:6379 -v /home/skidder/git/docker-dynamic-redis/redis.conf:/usr/local/etc/redis/redis.conf urlgrey/dynamic-redis:latest redis-server /usr/local/etc/redis/redis.conf

# Run APRS Dashboard, linking it to the Redis container
sudo docker run -d --link aprs_db:db -p 3000:3000 urlgrey/aprs-dashboard:latest

Note: To limit access to the PUT API, optionally set the APRS_API_TOKENS environment variable with a comma-separated list of API tokens. Default behavior is to allow access without the use of a token.

sudo docker run -d --link aprs_db:db -e APRS_API_TOKENS="secret123" -p 3000:3000 urlgrey/aprs-dashboard:latest

API

Record an APRS Message

Send an APRS message in the following JSON format:

Field	Required?	Type	Description
data	yes	string	ASCII-encoded APRS message
is_ax25	yes	boolean	Indicates whether the message is AX.25 encoded

Sample Payload

{
    "data": "WX4GSO-9>APN382,qAR,WD4LSS:!3545.18NL07957.08W#PHG5680/R,W,85NC,NCn Mount Shepherd Piedmont Triad NC",
    "is_ax25": false
}

Example

curl -X PUT -H "Content-Type: application/json" http://127.0.0.1:3000/api/v1/message -d @examples/sample_message.json

If access is limited by API token (see "Run" section), then include an X-API-KEY header:

curl -X PUT -H "X-API-KEY: secret123" -H "Content-Type: application/json" http://127.0.0.1:3000/api/v1/message -d @examples/sample_message.json

Observe output resembling the following in the APRS Dashboard console output:

[martini] Started PUT /api/v1/message for 127.0.0.1:63695
[martini] Completed 200 OK in 297.553us
