我想开发一个名为" backup"在cloudify中使用我自己的插件,但是当我运行该工作流时,出现以下错误
'backup' workflow execution failed: RuntimeError: Workflow failed: Task failed 'script_runner.tasks.run' -> Missing cloudify_agent runtime information. This most likely means that the Compute node never started successfully
我不明白为什么,有人能解决我这个问题吗? 这是我的主要蓝图代码和插件代码
我的主要蓝图
tosca_definitions_version: cloudify_dsl_1_2
imports:
- plugins/backup.yaml
- types/types.yaml
node_templates:
mynode:
type: cloudify.nodes.Compute
properties:
ip: "ip"
agent_config:
install_method: none
user: "user"
key: "key_uri"
myapp:
type: cloudify.nodes.ApplicationModule
interfaces:
test_platform_backup:
backup:
implementation: scripts/backup.sh
inputs:
port: 6969
post_backup:
implementation: scripts/post_backup.sh
relationships:
- type: cloudify.relationships.contained_in
target: mynode
我的插件代码:
from cloudify.decorators import workflow
from cloudify.workflows import ctx
from cloudify.workflows.tasks_graph import forkjoin
@workflow
def backup(operation, type_name, operation_kwargs, is_node_operation, **kwargs):
graph = ctx.graph_mode()
send_event_starting_tasks = {}
send_event_done_tasks = {}
for node in ctx.nodes:
if type_name in node.type_hierarchy:
for instance in node.instances:
send_event_starting_tasks[instance.id] = instance.send_event('Starting to run operation')
send_event_done_tasks[instance.id] = instance.send_event('Done running operation')
for node in ctx.nodes:
if type_name in node.type_hierarchy:
for instance in node.instances:
sequence = graph.sequence()
if is_node_operation:
operation_task = instance.execute_operation(operation, kwargs=operation_kwargs)
else:
forkjoin_tasks = []
for relationship in instance.relationships:
forkjoin_tasks.append(relationship.execute_source_operation(operation))
forkjoin_tasks.append(relationship.execute_target_operation(operation))
operation_task = forkjoin(*forkjoin_tasks)
sequence.add(
send_event_starting_tasks[instance.id],
operation_task,
send_event_done_tasks[instance.id])
for node in ctx.nodes:
for instance in node.instances:
for rel in instance.relationships:
instance_starting_task = send_event_starting_tasks.get(instance.id)
target_done_task = send_event_done_tasks.get(rel.target_id)
if instance_starting_task and target_done_task:
graph.add_dependency(instance_starting_task, target_done_task)
return graph.execute()

您的虚拟机似乎没有启动。
从你的代码中我无法理解你想要做什么。 您没有安装和代理,并且您没有与VM的结构连接,但您正在尝试在VM上运行操作。
您应该安装代理,例如删除“install_method:none”,或者将虚拟机连接添加到虚拟机并使用它运行操作。
