GroundWork 8 has default settings that will work for most environments, however there are some adjustment you can make, and may need to make, to allow it to be used in one or more of your networks. Various settings can be specified in the following configuration files in the gw8 directory.

gw8.env

Timezone

  • The TZ  variable sets the timezone for the cron job schedule. The default is Etc/UTC if not set. The format is the same as the Linux Timezone setting, e.g.,:

    America/New_York
America/Chicago
America/Denver
America/Phoenix
America/Los_Angeles

  • For example, to set the time zone to the West Coast of the USA, from the gw8 directory change the line in gw8.env file to:

    GW8_TZ=America/Los_Angeles

docker-compose.override.yml

Subnet used by the GW8 containers

  • The networking settings are designed to avoid conflicts in your networking setup. If you use the 172.16.0.0/12 subnet anywhere internally, you will want to make sure there isn't a conflict with the subnet used by Docker. You may not be able to use the system until you correct this conflict. You may adjust it in the docker-compose.override.yml file by specifying the subnet used by the GroundWork 8 containers. See the comments in the file for details. This file is in the gw8 directory.

Postgres InfluxDB ports

  • GroundWork Monitor 8.1.0 and later will ship with only ports 80, 443, and 5667 NSCA open. In some cases you may want direct access to postgres and/or InfluxDB, for example if you want to use InfluxDB for reporting data from a reporting designer. Port settings are specified in the docker-compose.yml file, but editing this file is not supported, and in fact is highly discouraged. To close or open InfluxDB or PostgreSQL ports, edit the docker-compose.override.yml file in the gw8 directory. Removing # will open the indicated ports:

    influxdb:
   # ports:
     # - "8086:8086"   # InfluxDB
    pg:
  # ports:
     # - "5432:5432"   # PostgreSQL

  • After making changes to docker-compose-override.yml, you must restart the GroundWork containers with the following: 

    docker-compose down
    CODE 
    docker-compose up -d
    CODE

    If you expose these ports, you should be prepared to manage the PostgreSQL/InfluxDB security administration. This primarily means password and identity management on these databases, which you can do as you would any postgres or influxdb system. In some cases it may require configuring firewalls on the host or its network.
