Extending Spin with a trigger and application

Manually

To test:

• cargo build --release
• Copy: cp ./target/release/trigger-timer .
• tar czvf trigger-timer.tar.gz trigger-timer
• Update the plugin manifest (trigger-timer.json):
  • Get the SHA: shasum -a 256 trigger-timer.tar.gz and copy it into the sha256 field
  • Update os and arch with values for your OS/Arch
  • Update the URL too, to reflect the directory where the tar file is
• spin plugin install --file ./trigger-timer.json --yes

Then you should be able to spin build --up the guest.

Pluginify

To test:

• create a spin-pluginify.toml file as follows:

name= "trigger-timer"
description= "Run Spin components at timed intervals"
homepage= "https://github.com/spinframework/spin/tree/main/examples/spin-timer"
version= "0.1.0"
spin_compatibility= ">=2.0"
license= "Apache-2.0"
package= "./target/release/trigger-timer"

• cargo build --release
• If pluginify plugin is not already installed run spin plugin install pluginify.
• spin pluginify --install

Then you should be able to spin build --up the guest.
