GroundWork 8 has default settings that will work for most environments, but 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. These various settings can be specified in the following configuration files in the gw8 directory.
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.
America/New_York America/Chicago America/Denver America/Phoenix America/Los_Angeles etc.
For example, to set the time zone to the West Coast of the USA, change the line to say:
NoMa sendEmail SMTP
SMTPSERVER_* - settings for NoMa (and, in 8.1.0 and above, Nagios) sendEmail SMTP server configuration. The default is the docker host port 25 if not set. For more detailed information see How to enable sendEmail with TLS with NoMa.
SMTPSERVER_SERVERPORT=<server>:<port> SMTPSERVER_TLS=<auto|yes|no> SMTPSERVER_AUTHUSER=<username> SMTPSERVER_AUTHPASS=<password>
SMTPSERVER_SERVERPORT=smtp.gmail.com:587 SMTPSERVER_TLS=yes SMTPSERVER_AUTHUSERemail@example.com SMTPSERVER_AUTHPASS=mygmailapppassword
Subnet used by the GW8 containersThe 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.ymlfile by specifying the subnet used by the GW8 containers. See the comments in the file for details. This file is in the
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:
After making changes to
docker-compose-override.yml, you must restart the GroundWork containers with:
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.
