Storj metrics missing when is custom name for storagenode is used

[Samgarr]

Hello, i think easiest option instalation doesn't export storagenode metrics if storagenode using custom name for container.

CONTAINER ID   IMAGE                          COMMAND                  CREATED              STATUS              PORTS                                                  NAMES
e25e997bebc2   storjlabs/storagenode:latest   "/entrypoint"            13 hours ago         Up 13 hours         127.0.0.1:14002->14002/tcp, 0.0.0.0:28967->28967/tcp   storj32

Docker container for storj-exporter have "STORJ_HOST_ADDRESS=storagenode", which does not exists.

"Env": [               
  "PATH=/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",
  "LANG=C.UTF-8",

  "PYTHON_GET_PIP_SHA256=6e0bb0a2c2533361d7f297ed547237caf1b7507f197835974c0dd7eba998c53c",
  "STORJ_HOST_ADDRESS=storagenode",
  "STORJ_API_PORT=14002",
  "STORJ_EXPORTER_PORT=9651"
],

After fixing this ENV variable everything works. It would be nice mention this directly in README.

Thanks, I will update the readme to make it more clear and add some examples for multiple nodes.

Currently STORJ_HOST_ADDRESS is mentioned here along with other env vars which you can set on the docker command line with -e STORJ_HOST_ADDRESS=<ip or name of storagenode container>" to override the default
