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. Copy orchestra SSH key to the servers to be managed (you can use <span title="`orchestra@panel:~ ssh-copy-id root@server.address`">`ssh-copy-id`</span>: ), then Add the servers to be managed by orchestra into the servers section `/admin/orchestration/servers`, then copy orchestra's SSH pubkey to them
|
||||
|
||||
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
|
||||
|
||||
1. Copy orchestra SSH key to the servers to be managed, you can use `ssh-copy-id`:
|
||||
```bash
|
||||
orchestra@panel:~ ssh-copy-id root@server.address
|
||||
```
|
||||
Then add the servers to orchestra using the web interface `/admin/orchestration/servers`, check that the SSH connection is working and Orchestra can report the uptime of the servers.
|
||||
|
||||
2. Now configure service by service (domains, databases, webapps, websites, ...):
|
||||
1. Add the route via `/admin/orchestration/route/`
|
||||
2. Configure related settings on `/admin/settings/setting/`
|
||||
3. If required, configure related resources like Account disc limit, VPS traffic, etc `/resources/resource/`
|
||||
3. Test that everything works as expected by creating and deleting service instances
|
||||
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
|
||||
|
||||
3. Configure billing by adding services `/admin/services/service/add/` and plans `/admin/plans/plan/`. Once a service is created hit the *Update orders* button to create the orders for the existing service instances.

|

|
||||
### 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

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]
|
||||
```
|
||||
from django.db import models
|
||||
|
||||
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)
|
||||
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, refere to [Django Admin documentation](https://docs.djangoproject.com/en/1.9/ref/contrib/admin/) for further customization.
|
||||
```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):

|

verbose_name = _("UNIX cron")
|
||||
model = 'crons.CronTab'
|

def prepare(self):
|

super(UNIXCronBackend, self).prepare()
|

self.accounts = set()
|

for crontab in account.crontabs.all():

self.append("
|
||||
# if crontab is None:
|
||||
# self.append("rm -f %(crontab_path)s" % context)
