Run Grafana Agent in flow mode in a Docker container

Grafana Agent is available as a Docker container image on the following platforms:

Before you begin

  • Install Docker on your computer.

  • Create and save a Grafana Agent River configuration file on your computer, for example:

    river 
    logging {
  level  = "info"
  format = "logfmt"
}

Run a Linux Docker container

To run Grafana Agent in flow mode as a Linux Docker container, run the following command in a terminal window:

shell 
docker run \
  -e AGENT_MODE=flow \
  -v CONFIG_FILE_PATH:/etc/agent/config.river \
  -p 12345:12345 \
  grafana/agent:latest \
    run --server.http.listen-addr=0.0.0.0:12345 /etc/agent/config.river

Replace CONFIG_FILE_PATH with the path of the configuration file on your host system.

You can modify the last line to change the arguments passed to the Grafana Agent binary. Refer to the documentation for run for more information about the options available to the run command.

Note

Make sure you pass --server.http.listen-addr=0.0.0.0:12345 as an argument as shown in the example above. If you don’t pass this argument, the debugging UI won’t be available outside of the Docker container.
