mesos-proxy

Access logs of Marathon tasks from the command line.

main.go A proxy server to access files from a Mesos slaves sandbox.

logs works with main.go allowing you to retrieve stdout / stderr from a running Marathon task.

Install

Build the server component

make

Install the binary on an accessible http server so that it's accessible @ https://web-mesos-proxy.${HOST}

If you have Marathon configured to expose services through a web server, you can deploy mesos-proxy using the following config.

{
  "id": "/mesos-proxy/web",
  "instances": 1,
  "cpus": 0.1,
  "mem": 100,
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "mongey/mesos-proxy:latest",
      "network": "BRIDGE",
      "portMappings": [
        {
          "containerPort": 8181,
          "protocol": "tcp",
          "name": "http"
        }
      ]
    }
  },
  "healthChecks": [
    {
      "protocol": "TCP",
      "portIndex": 0,
      "gracePeriodSeconds": 30,
      "intervalSeconds": 30,
      "timeoutSeconds": 10,
      "maxConsecutiveFailures": 3,
      "ignoreHttp1xx": false
    }
  ]
}

To retrieve logs you will need ruby installed, and to install the httparty gem

gem install httparty

Usage

The logs script assumes that marathon is accessible via https://marathon.${HOST} and that mesos-log-proxy is available at https://web-mesos-proxy.${HOST}

HOST=my-host.com ./logs

Combine it with fzf to search through marathon tasks

export HOST=my-host.com
logs $(./logs | fzf)
