Application for automatically updating prometheus targets file.
To configure the application, use environment variable DISCOVERY_CONFIG with such format:
{
"outputFile": "targets.json", // output targets file path
"checkEverySeconds": 10, // check interval in seconds
"jobs": {
"jobName": { // prometheus job name
"type": "fargate",
"cluster": "my-cluster", // name of the cluster
"targetPort": 9999 // metrics port of the target application
}
}
}At the moment only fargate detection is supported. This application should run alongside prometheus so that it can access the targets file.
Intended usage is running as side-cart inside the same container as prometheus does.
