ActionRunner ActionRunner是Action的执行环境， Action Runner实际上就是一系列的工作进程，ActionRunner根据StackStorm调度来进行执行Action，可以通过命令查询到进程： # st2ctl status ##### st2 components status ##### st2actionrunner PID: 36192 st2actionrunner PID: 36194 st2api PID: 39436 st2api PID: 39443 st2stream PID: 36236 st2auth PID: 36243 st2workflowengine PID: 36294 st2scheduler PID: 36301 ActionRunner StackStorm支持不同类型的执行方式，比如Shell脚本，Python脚本或者HTTP调用等等，这些是以插件的形式存在的，StackStorm内置了基本的一些Action Runner，如下表所示。除了StackStorm的内置类型ActionRunner，当然也可以自定义ActionRunner。 local-shell-cmd This is the local runner. This runner executes a Linux command on the same host where StackStorm components are running. local-shell-script This is the local runner. Actions are implemented as scripts. They are executed on the same hosts where StackStorm components are running. remote-shell-cmd This is a remote runner. This runner executes a Linux command on one or more remote hosts provided by the user. remote-shell-script This is a remote runner. Actions are implemented as scripts. They run on one or more remote hosts provided by the user. python-script This is a Python runner. Actions are implemented as Python classes with arun method. They run locally on the same machine where StackStorm components are running. http-request HTTP client which performs HTTP requests for running HTTP actions. action-chain This runner supports executing simple linear work-flows. mistral-v2 Those runners are built on top of the Mistral OpenStack project and support executing complex work-flows. cloudslang This runner is built on top of the CloudSlang project and supports executing complex workflows. inquirer This runner provides the core logic of the :doc:Inquiries </inquiries> feature.
