coversd interfaces with and wraps the mirror cover conroller.
covers is a commandline utility for controlling the covers.
Configuration is read from json files that are installed by default to /etc/coversd.
A configuration file is specified when launching the server, and the covers frontend will search this location when launched.
The configuration options are:
{
"daemon": "onemetre_covers", # Run the server as this daemon. Daemon types are registered in `rockit.common.daemons`.
"log_name": "coversd@onemetre", # The name to use when writing messages to the observatory log.
"control_machines": ["OneMetreDome", "OneMetreTCS"], # Machine names that are allowed to control (rather than just query) state. Machine names are registered in `rockit.common.IP`.
"serial_port": "/dev/covers",
"serial_baud": 9600,
"serial_timeout": 5,
"move_timeout": 30
}The automated packaging scripts will push 4 RPM packages to the observatory package repository:
| Package | Description |
|---|---|
| rockit-covers-server | Contains the coversd server and systemd service file. |
| rockit-covers-client | Contains the covers commandline utility for controlling the covers server. |
| python3-rockit-covers | Contains the python module with shared code. |
| rockit-covers-data-onemetre | Contains the json configuration for the W1m. |
After installing packages, the systemd service should be enabled:
sudo systemctl enable --now coversd@<config>
where config is the name of the json file for the appropriate telescope.
Now open a port in the firewall:
sudo firewall-cmd --zone=public --add-port=<port>/tcp --permanent
sudo firewall-cmd --reload
where port is the port defined in rockit.common.daemons for the daemon specified in the config.
New RPM packages are automatically created and pushed to the package repository for each push to the master branch.
These can be upgraded locally using the standard system update procedure:
sudo yum clean expire-cache
sudo yum update
The daemon should then be restarted to use the newly installed code:
sudo systemctl restart coversd@<config>
The camera server and client can be run directly from a git clone:
./coversd onemetre.json
COVERSD_CONFIG_PATH=./onemetre.json ./covers status
