This is thread that interacts with a VIM. It processes TASKs sequentially against a single VIM.
-The tasks are stored at database in table vim_actions
+The tasks are stored at database in table vim_wim_actions
The task content is (M: stored at memory, D: stored at database):
MD instance_action_id: reference a global action over an instance-scenario: database instance_actions
MD task_index: index number of the task. This together with the previous forms a unique key identifier
params: list with the params to be sent to the VIM for CREATE or FIND. For DELETE the vim_id is taken from other related tasks
find: (only for CREATE tasks) if present it should FIND before creating and use if existing. Contains the FIND params
depends_on: list with the 'task_index'es of tasks that must be completed before. e.g. a vm creation depends on a net creation
+ can contain an int (single index on the same instance-action) or str (compete action ID)
sdn_net_id: used for net.
tries:
interfaces: used for VMs. Each key is the uuid of the instance_interfaces entry at database
vim_status: VIM status of the element. Stored also at database in the instance_XXX
M depends: dict with task_index(from depends_on) to task class
M params: same as extra[params] but with the resolved dependencies
- M vim_interfaces: similar to extra[interfaces] but with VIM information. Stored at database in the instance_XXX but not at vim_actions
- M vim_info: Detailed information of a vm,net from the VIM. Stored at database in the instance_XXX but not at vim_actions
+ M vim_interfaces: similar to extra[interfaces] but with VIM information. Stored at database in the instance_XXX but not at vim_wim_actions
+ M vim_info: Detailed information of a vm,net from the VIM. Stored at database in the instance_XXX but not at vim_wim_actions
MD error_msg: descriptive text upon an error.Stored also at database instance_XXX
MD created_at: task creation time
MD modified_at: last task update time. On refresh it contains when this task need to be refreshed
