* if variable to bind an exporter container to a host port is set, have matrix-domain.conf (nginx) support this * manipulate some variables to account for just port numbers or 0.0.0.0 IPs * Make sure to use the right variable in the init.yml files * Update roles/matrix-prometheus-node-exporter/tasks/init.yml Co-authored-by: Slavi Pantaleev <slavi@devture.com> * Update roles/matrix-prometheus-postgres-exporter/tasks/init.yml Co-authored-by: Slavi Pantaleev <slavi@devture.com> * remove extraneous variables and whitespace Co-authored-by: Luca Bilke <luca@gmail.com> Co-authored-by: Slavi Pantaleev <slavi@devture.com>
