# svc
|
|
## Goals
|
|
|
|
- Standardize service deployments to have _one_ syntax and _one_ function for the following:
|
|
1. Deployment
|
|
2. Checking the status of a deployed service
|
|
3. Killing off an old instance of the service
|
|
|
|
- Create a command line tool that deploys a service to a given provider
|
|
given configuration in a simple yaml manifest (see example [here](https://github.com/Xe/tools/tree/master/svc/sample))
|
|
|
|
- Persist a mapping of service names -> identifier for keeping track of past deployments
|
|
|
|
## Subcommands
|
|
|
|
| cmd | what it does |
|
|
|:--- |:------------ |
|
|
| `spawn` | Launches a new instance of the given service name on the given backend |
|
|
| `ps` | Inquires the status of all known deployed services and displays them in a clever little grid |
|
|
| `create` | Creates a directory hierarchy at $SVCROOT for a new service by name |
|
|
| `remove` | Stops a service and undeploys it from a given backend |
|
|
| `cycle` | Pulls the latest image and restarts the service with the new image |
|
|
| `inspect` | Inspects a single service, outputting its state in json |
|
|
|
|
### `spawn`
|
|
|
|
Launches a new instance of the given service name on the given backend
|
|
|
|
Usage: `svc spawn [options] <servicename> <backend>`
|
|
|
|
Options:
|
|
|
|
| option | type | effect |
|
|
|:------ |:---- |:------ |
|
|
| `-kahled` | bool | Creates another instance of this service if one exists on any backend, fails if service is exclusive and already spawned |
|
|
|
|
### `ps`
|
|
|
|
Inquires the status of all known deployed services and displays them in a clever little grid
|
|
|
|
Usage `svc ps [options] [servicename]`
|
|
|
|
Options:
|
|
|
|
| option | type | effect |
|
|
|:------ |:---- |:------ |
|
|
| `-backend` | string | If set, only show results for services running on the given backend |
|
|
| `-match` | string | If set, regex-match on service details |
|
|
| `-format` | string | Pretty-print container status using a Go template |
|
|
|
|
### `create`
|
|
|
|
Creates a directory hierarchy at $SVCROOT for a new service by name
|
|
|
|
Usage: `svc create <servicename>`
|
|
|
|
### `remove`
|
|
|
|
Stops a service and removes it from a given backend
|
|
|
|
Usage: `svc remove <servicename>`
|
|
|
|
### `cycle`
|
|
|
|
Pulls the latest image and restarts the service with the new image
|
|
|
|
This command ***NEVER*** stops the old container until the new container is running and passes
|
|
healthchecks.
|
|
|
|
Usage: `svc cycle <servicename>`
|
|
|
|
### `inspect`
|
|
|
|
Inspects a single service from a single backend, outputting its state in json
|
|
|
|
By default this will output a list of the inspect state of all matching instances of a service
|
|
running on a particular backend.
|
|
|
|
Usage: `svc inspect <servicename> <backend>`
