### Quick start
|
||||
0. Install orchestra following any of these methods:
|
||||
1. [PIP-only, Fast deployment setup (demo)](README.md#fast-deployment-setup)
|
||||
2. [Docker container (development)](INSTALLDEV.md)
|
||||
3. [Install on current system (production)](INSTALL.md)
|
||||
1. Add the servers that you want to manage on `/admin/orchestration/servers` and copy orchestra's SSH pubkey to them
|
||||
`orchestra@panel:~ ssh-copy-id root@server.address`
|
||||
2. Now configure service by service (domains, databases, webapps, websites...):
|
||||
1. Add the route through `/admin/orchestration/route/`
|
||||
2. Check and configure related settings on `/admin/settings/setting/`
|
||||
3. Configure related resources if needed `/resources/resource/`, like Account Disc limit and traffic.
|
||||
3. Test that everything works by creating and deleting services
|
||||
4. Do the same for the other services
|
||||
3. Configure billing by adding services `/admin/services/service/add/` and plans `/admin/plans/plan/`
|
||||
1. Once a service is created hit the *Update orders* button
|
||||
|
||||
|
||||
### Architecture
|
||||
Orchestration
|
||||
Orders
|
||||
|
||||
|
||||
### Creating new services
|
||||
1. Think about if the service can fit into one of the existing models like: SaaS or WebApps, refere to the related documentation if that is the case.
|
||||
2. Create a new django app using startapp management command. For ilustrational purposes we will create a crontab services that will allow orchestra to manage user-based crontabs.
|
||||
`python3 manage.py startapp crontabs`
|
||||
3. Add the new *crontabs* app to the `INSTALLED_APPS` in your project's `settings.py`
|
||||
3. Create a `models.py` file with the data your service needs to keep in order to be managed by orchestra
|
||||
```python
|
||||
from django.db import models
|
||||
|
||||
class CrontabSchedule(models.Model):
|
||||
account = models.ForeignKey('accounts.Account', verbose_name=_("account"))
|
||||
minute = models.CharField(_("minute"), max_length=64, default='*')
|
||||
hour = models.CharField(_("hour"), max_length=64, default='*')
|
||||
day_of_week = models.CharField(_("day of week"), max_length=64, default='*')
|
||||
day_of_month = models.CharField(_("day of month"), max_length=64, default='*')
|
||||
month_of_year = models.CharField(_("month of year"), max_length=64, default='*')
|
||||
|
||||
class Meta:
|
||||
ordering = ('month_of_year', 'day_of_month', 'day_of_week', 'hour', 'minute')
|
||||
|
||||
def __str__(self):
|
||||
rfield = lambda f: f and str(f).replace(' ', '') or '*'
|
||||
return "{0} {1} {2} {3} {4} (m/h/d/dM/MY)".format(
|
||||
rfield(self.minute), rfield(self.hour), rfield(self.day_of_week),
|
||||
rfield(self.day_of_month), rfield(self.month_of_year),
|
||||
)
|
||||
|
||||
class Crontab(models.Model):
|
||||
account = models.ForeignKey('accounts.Account', verbose_name=_("account"))
|
||||
schedule = models.ForeignKey(CrontabSchedule, verbose_name=_("schedule"))
|
||||
description = models.CharField(_("description"), max_length=256, blank=True)
|
||||
command = models.TextField(_("content"))
|
||||
|
||||
def __str__(self):
|
||||
return (self.description or self.command)[:32]
|
||||
```
|
||||
|
||||
4. Create a `admin.py` to enable the admin interface
|
||||
```python
|
||||
from django.contrib import admin
|
||||
from .models import CrontabSchedule, Crontab
|
||||
|
||||
class CrontabScheduleAdmin(admin.ModelAdmin):
|
||||
pass
|
||||
|
||||
class CrontabAdmin(admin.ModelAdmin):
|
||||
pass
|
||||
|
||||
admin.site.register(CrontabSchedule, CrontabScheduleAdmin)
|
||||
admin.site.register(Crontab, CrontabAdmin)
|
||||
|
||||
|
||||
5. Create a `api.py` to enable the REST API.
|
||||
6. Create a `backends.py` fiel with the needed backends for service orchestration and monitoring
|
||||
```python
|
||||
import os
|
||||
import textwrap
|
||||
from django.utils.translation import ugettext_lazy as _
|
||||
from orchestra.contrib.orchestration import ServiceController, replace
|
||||
from orchestra.contrib.resources import ServiceMonitor
|
||||
|
||||
class UNIXCronBackend(ServiceController):
|
||||
"""
|
||||
Basic UNIX cron support.
|
||||
"""
|
||||
verbose_name = _("UNIX cron")
|
||||
model = 'crons.CronTab'
|
||||
|
||||
def prepare(self):
|
||||
super(UNIXCronBackend, self).prepare()
|
||||
self.accounts = set()
|
||||
|
||||
def save(self, crontab):
|
||||
self.accounts.add(crontab.account)
|
||||
|
||||
def delete(self, crontab):
|
||||
self.accounts.add(crontab.account)
|
||||
|
||||
def commit(self):
|
||||
for account in self.accounts:
|
||||
crontab = None
|
||||
self.append("echo '' > %(crontab_path)s" % context)
|
||||
chown
|
||||
for crontab in account.crontabs.all():
|
||||
self.append("
|
||||
# if crontab is None:
|
||||
# self.append("rm -f %(crontab_path)s" % context)
|
||||
```
|
||||
7. Configure the routing
|
||||
|
||||
|
||||
|
||||
|
||||
# TODO save serialized versions ob backendoperation.instance in order to allow backend reexecution of deleted objects
