Hooks

hooks are set of commands and actions that are run before (pre) and after (post) sandbox creation. They are wrappers around tc create command. The hooks are defined per topology in it’s corresponding infra dir (INFRA_DIR/TOPOLOGY/hooks.json)

Example:

{
  "pre": [
    {
      "command": "tc build --kind extension",
      "dir": "./extensions/bg-task",
      "on_failure": "exit"
    }
  ],
  "post": [
    {
      "command": "tc test -s {{sandbox}} -e {{env}}",
      "on_failure": "exit"
    }
  ]
}

In the above, building an extension is run before creating the topology and test is run after creating the topology in a sandbox. The hooks are run sequentially. on_failure specifies a command to run or identifiers like exit, notify etc.
