# DESCRIPTION
|
||
|
||
*service* is a tool that starts, stops, lists, queries, creates or removes system services.
|
||
*service* abstracts their configuration and handles their dependencies to one another.
|
||
|
||
Some general concepts about WeirdOS’ services management and boot procedure can be found in *service*(7).
|
||
|
||
# USAGE
|
||
|
||
## Identifying Services
|
||
|
||
service show <id>
|
||
|
||
service status [-v|--verbose] [id [id [...]]]
|
||
|
||
Service ids are the name of a service, that may be prefixed by the name of their environment and a slash ('/').
|
||
|
||
*service show* shows all of a service’s relationship to other services as well as its full configuration as handled by `service`.
|
||
|
||
*service status* shows the status of one or multiple services, including whether they are currently running or not.
|
||
If no parameter is provided to the `status` command, it will show the status of all services.
|
||
If the `--verbose` flag is provided, informations about what tokens a service produces or consumes, as well as the ports it reserves, will be displayed as well.
|
||
|
||
## Starting Services
|
||
|
||
service start <id>
|
||
|
||
When *service* starts services, it also starts their dependencies.
|
||
|
||
If a service is depended on by a non-runnable service, the non-runnable services will have their configuration and deployable files generated once its last dependency is started.
|
||
An example for this is a static website that depends on a web server: if the web server is started, the static website’s files and possible configuration will be generated or installed where they will be served.
|
||
|
||
To force a service the use of a particular provider, the syntax token_id=service_id can be used.
|
||
If providers are guessed, those from the same environment as the service to be created are used first, if any.
|
||
Services from the *root* environment are tried next.
|
||
To force *not* using a token, the token_id=none syntax can be used.
|
||
|
||
The type=service_type syntax can be used to specify what kind of service is to be created if its name does not match a known service definition.
|
||
|
||
The domain=example.tld syntax can be used to specify domain names when creating services that require one.
|
||
|
||
## Stopping Services
|
||
|
||
service stop <id>
|
||
|
||
## Adding Services
|
||
|
||
service add <id> [options]
|
||
|
||
The *service add* command can be used to create a service.
|
||
Only services that have been “added” to the list of known services can be started.
|
||
|
||
It takes as first parameter the *id* of the service to create.
|
||
|
||
The service type defaults to the name of the service to be created.
|
||
|
||
## Removing Services
|
||
|
||
service del <id> [options]
|
||
|
||
The *service del* command removes a service from the system.
|
||
Be careful, as this command also removes its configuration and data.
|
||
|
||
*service del* will not let you remove services that are being depended on unless you provide a `--force` flag.
|
||
|
||
*service del* will stop services before removing them.
|
||
|
||
# EXAMPLES
|
||
|
||
## Starting a Service
|
||
|
||
service start gitea
|
||
|
||
## Registering a Single Service
|
||
|
||
service add postgresql
|
||
|
||
service start postgresql
|
||
|
||
## Registering Multiple Services with Dependencies
|
||
|
||
service add nginx
|
||
|
||
service add postgresql
|
||
|
||
service add gitea http=nginx postgresql=postgresql domain=gitea.test
|
||
|
||
In this example, the dependencies of the “gitea” service could have been guessed automatically.
|
||
The following example does the exact same thing but lets *service* guess dependencies.
|
||
|
||
service add nginx
|
||
|
||
service add postgresql
|
||
|
||
service add gitea domain=gitea.test
