Assets
======
This directory contains tooling for managing assets used by the bots. The
primary entry point is assets.py, which allows a user to add, remove, upload,
and download assets.
Assets are stored in Google Storage, named for their version number.
Individual Assets
-----------------
Each asset has its own subdirectory with the following contents:
* VERSION: The current version number of the asset.
* [optional] create.py: Script which creates the asset, implemented by the user and called by `sk asset upload`.
* [optional] create\_and\_upload.py: User-implemented convenience script which wraps `sk asset upload` in whatever way makes sense for the asset.
Examples
-------
As with all uses of `sk asset`, the following will only work if you have a
google.com account and have authenticated with
`gcloud auth application-default login`.
Add a new asset and upload an initial version.
```
$ sk asset add myasset
Do you want to add a creation script for this asset? (y/n): n
$ sk asset upload --in ${MY_ASSET_LOCATION} myasset
$ git commit
```
Add an asset whose creation can be automated.
```
$ sk asset add myasset
Do you want to add a creation script for this asset? (y/n): y
Created infra/bots/assets/myasset/create.py; you will need to add implementation before uploading the asset.
$ vi infra/bots/assets/myasset/create.py
(implement the create_asset function)
$ sk asset upload myasset
$ git commit
```
Update an asset.
```
(update the create.py script)
$ sk asset upload myasset
(assuming infra/bots/assets/myasset/VERSION has been updated by the previous
command, regenerate tasks.json per infra/bots/README:)
$ make -C infra/bots train
$ git commit
```
