Resolve ungraceful docker-compose stop

[mdr0id]

During stopping procedures to update/restart nodes, it was noticed that the mutli exporter does not gracefully shutdown:

$ docker-compose stop
Stopping ecc_zcashd_exporter_zcashd_1              ... 
Stopping ecc_zcashd_exporter_ecc_zcashd_exporter_1 ... 
Stopping ecc_zcashd_exporter_grafana_1             ... done
Stopping ecc_zcashd_exporter_prometheus_1          ... done
Stopping ecc_zcashd_exporter_loki_1                ... 
Stopping monitoring_node_exporter                  ... done

ERROR: for ecc_zcashd_exporter_loki_1  UnixHTTPConnectionPool(host='localhost', port=None): Read timed out. (read timeout=70)

ERROR: for ecc_zcashd_exporter_zcashd_1  UnixHTTPConnectionPool(host='localhost', port=None): Read timed out. (read timeout=70)

ERROR: for ecc_zcashd_exporter_ecc_zcashd_exporter_1  UnixHTTPConnectionPool(host='localhost', port=None): Read timed out. (read timeout=70)
ERROR: An HTTP request took too long to complete. Retry with --verbose to obtain debug information.
If you encounter this issue regularly because of slow network conditions, consider setting COMPOSE_HTTP_TIMEOUT to a higher value (current value: 60).

To resolve, set your local session var accordly, or update vi /etc/profile and source /etc/profile

export COMPOSE_HTTP_TIMEOUT=500

After updating above to your environment's preference, docker-compose stop should now shutdown all pods gracefully:

$ docker-compose stop
Stopping ecc_zcashd_exporter_zcashd_1              ... done
Stopping ecc_zcashd_exporter_ecc_zcashd_exporter_1 ... done
Stopping ecc_zcashd_exporter_grafana_1             ... done
Stopping ecc_zcashd_exporter_prometheus_1          ... done
Stopping ecc_zcashd_exporter_loki_1                ... done
Stopping monitoring_node_exporter                  ... done
