Language packs can be used to extend Knative Functions to support additional runtimes, function signatures, operating systems, and installed tooling for functions. Language Packs are distributed through Git repositories or as a directory on a disc.
For more information see the language pack documentation.
Using external Git repositories¶
When creating a new function, a Git repository can be specified as the source for the template files. The Knative Sandbox maintains a set of example templates which can be used during project creation.
For example, you can run the following command to use the
metacontroller template for Node.js:
func create myfunc -l nodejs -t metacontroller --repository https://github.com/knative-sandbox/func-tastic
Installing language packs locally¶
Language packs can be installed locally by using the
func repository command.
For example, to add the Knative Sandbox example templates, you can run the following command:
func repository add knative https://github.com/knative-sandbox/func-tastic
After the Knative Sandbox example templates are installed, you can use the
metacontroller template by specifying the
knative prefix in the
func create -t knative/metacontroller -l nodejs my-controller-function
