exec

The exec step type hands full process ownership to another command, so your workflows can launch terminal-native tools — interactive sessions, REPLs, or port-forwards — exactly as if you had run them yourself.

steps:
  - name: session
    type: exec
    command: aws ssm start-session --target i-0123456789abcdef0

Fields

command

Required. Command to execute.

working_directory

Optional directory where the command starts.

env

Optional environment variables for the command.

Because the process is replaced, an exec step must be the final step. Later workflow steps cannot run after process replacement.
