Dockerized Raintank Collector

Original non dockerized Raintank Collector is complicated (node + go installation), so I've prepared quicker (~10sec) deployment option. Quick start:

docker run \
    -d \
    -p 8284:8284 \
    -e "RAINTANK_apiKey=<RAINTANK API KEY>" \
    -e "RAINTANK_collector_name=<COLLECTOR NAME>" \
    monitoringartist/raintank-collector:latest

Configuration

You can use environment variables to configure Raintank collector container:

Environment variable	Default value	Note
RAINTANK_apiKey		use your API key
RAINTANK_collector_name	<random string>
RAINTANK_logLevel	ERROR	Options: OFF, FATAL, ERROR, WARN, INFO, DEBUG, TRACE, ALL
RAINTANK_numCPUs	1
RAINTANK_probeServerPort	8284	use some free port
RAINTANK_serverUrl	https://controller.raintank.io

Example:

docker run \
    -d \
    --name raintank-collector \
    -p 8284:8284 \
    -e "RAINTANK_apiKey=<RAINTANK API KEY>" \
    -e "RAINTANK_collector_name=<COLLECTOR NAME>" \
    -e "RAINTANK_numCPUs=1" \
    -e "RAINTANK_logLevel=ALL" \
    -e "RAINTANK_probeServerPort=8284" \
    monitoringartist/raintank-collector:latest

Troubleshooting

Always set up RAINTANK_logLevel=ALL and then check docker container logs, for example:

# docker logs -f raintank-collector
