For managing default parameters for Blender and FFmpeg, as well as for
|
||||
mixed-platform render farms, Flamenco uses *variables*.
|
||||
Flamenco Manager reads its configuration from `flamenco-manager.yaml`, located
|
||||
next to the `flamenco-manager` executable. The previous chapters
|
||||
([Shared Storage][storage] and [Variables][variables]) also described parts of
|
||||
that configuration file.
|
||||
|
||||
Each variable consists of:
|
||||
[storage]: {{< ref "shared-storage" >}}
|
||||
[variables]: {{< ref "usage/variables/multi-platform" >}}
|
||||
|
||||
- Its **name**: just a sequence of letters, like `blender` or `whateveryouwant`.
|
||||
- Its **values**: per *platform* and *audience*, described below.
|
||||
## Example Configuration
|
||||
|
||||
The variables are configured in `flamenco-manager.yaml`.
|
||||
|
||||
Here is an example `blender` variable:
|
||||
This is an example `flamenco-manager.yaml` file:
|
||||
|
||||
```yaml
|
||||
_meta:
|
||||
version: 3
|
||||
manager_name: Flamenco Manager
|
||||
database: flamenco-manager.sqlite
|
||||
listen: :8080
|
||||
autodiscoverable: true
|
||||
local_manager_storage_path: ./flamenco-manager-storage
|
||||
shared_storage_path: /path/to/storage
|
||||
shaman:
|
||||
enabled: true
|
||||
garbageCollect:
|
||||
period: 24h0m0s
|
||||
maxAge: 744h0m0s
|
||||
extraCheckoutPaths: []
|
||||
task_timeout: 10m0s
|
||||
worker_timeout: 1m0s
|
||||
blocklist_threshold: 3
|
||||
task_fail_after_softfail_count: 3
|
||||
variables:
|
||||
blender:
|
||||
values:
|
||||
- platform: linux
|
||||
value: /home/sybren/Downloads/blenders/blender-3.2.2-release/blender
|
||||
value: blender
|
||||
- platform: windows
|
||||
value: B:\Downloads\blenders\blender-3.2.2-release\blender.exe
|
||||
value: blender
|
||||
- platform: darwin
|
||||
value: /home/sybren/Downloads/blenders/blender-3.2.2-release/blender
|
||||
value: blender
|
||||
blenderArgs:
|
||||
values:
|
||||
- platform: all
|
||||
value: -b -y
|
||||
```
|
||||
|
||||
Whenever a Worker gets a task that contains `{blender}`, that'll be replaced by
|
||||
the appropriate value for that worker.
|
||||
|
||||
## Platform
|
||||
|
||||
**The goal of the variables system is to cater for different platforms.**
|
||||
Blender will very likely be installed in different locations on Windows and
|
||||
Linux. It might even require some different parameters for your farm, depending
|
||||
on the platform. The variables system allows you to configure this.
|
||||
|
||||
The platform can be `windows`, `linux`, or `darwin` for macOS. Other platforms
|
||||
are also allowed, if you happen to use them in your farm.
|
||||
|
||||
## Two-way Variables for Mixed-platform Farms
|
||||
|
||||
Variables are not just used to point to specific things, like `blender` above.
|
||||
They can also tell Flamenco that the path `/media/shared/flamenco` on Linux is
|
||||
the same as `S:\flamenco` on Windows, or `/Volumes/shared/flamenco` on macOS.
|
||||
This is documented further in [Two-way Variables for Multi-Platform Support][two-way].
|
||||
|
||||
## Custom Job Types
|
||||
|
||||
This documentation section focuses on pre-existing variables, `blender` and
|
||||
`blenderArgs`. There is nothing special about these. Apart from being part of
|
||||
Flamenco's default configuration, that is. When you go the more advanced route
|
||||
of creating your own [custom job types][jobtypes] you're free to create your own
|
||||
set of variables to suit your needs.
|
||||
|
||||
[jobtypes]: {{< ref "usage/job-types" >}}
|
||||
[two-way]: {{< ref "usage/variables/multi-platform" >}}
|
||||
|
||||
## Advanced: Audience
|
||||
|
||||
The audience of a value is who that value is for: `workers`, `users`, or `all`
|
||||
if there is no difference in value for workers and users.
|
||||
|
||||
This is an advanced feature, and was introduced for in-the-cloud render farms.
|
||||
In such situations, the location where the workers store the rendered frames
|
||||
might be different from where users go to pick them up.
|
||||
|
||||
- `all`: values that are used for all audiences. This is the default, and is
|
||||
what's used in the above example (because there is no `audience` mentioned).
|
||||
- `users`: values are used when submitting jobs from Blender and showing them in
|
||||
the web interface.
|
||||
- `workers`: values that are used when sending tasks to workers.
|
||||
The usual way to create a configuration file is simply by starting Flamenco
|
||||
Manager. If there is no config file yet, it will start the setup assistant to
|
||||
create one. If for any reasons the setup assistant is not usable for you, you
|
||||
can use the above example to create `flamenco-manager.yaml` yourself.
