| """" |
| 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_wim_actions |
| Several vim_wim_actions can refer to the same element at VIM (flavor, network, ...). This is somethng to avoid if RO |
| is migrated to a non-relational database as mongo db. Each vim_wim_actions reference a different instance_Xxxxx |
| In this case "related" colunm contains the same value, to know they refer to the same vim. In case of deletion, it |
| there is related tasks using this element, it is not deleted, The vim_info needed to delete is transfered to other task |
| |
| 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 |
| MD datacenter_vim_id: should contain the uuid of the VIM managed by this thread |
| MD vim_id: id of the vm,net,etc at VIM |
| MD item: database table name, can be instance_vms, instance_nets, TODO: datacenter_flavors, datacenter_images |
| MD item_id: uuid of the referenced entry in the previous table |
| MD action: CREATE, DELETE, FIND |
| MD status: SCHEDULED: action need to be done |
| BUILD: not used |
| DONE: Done and it must be polled to VIM periodically to see status. ONLY for action=CREATE or FIND |
| FAILED: It cannot be created/found/deleted |
| FINISHED: similar to DONE, but no refresh is needed anymore. Task is maintained at database but |
| it is never processed by any thread |
| SUPERSEDED: similar to FINSISHED, but nothing has been done to completed the task. |
| MD extra: text with yaml format at database, dict at memory with: |
| 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. |
| interfaces: used for VMs. Each key is the uuid of the instance_interfaces entry at database |
| iface_id: uuid of intance_interfaces |
| sdn_port_id: |
| sdn_net_id: |
| vim_info |
| created_items: dictionary with extra elements created that need to be deleted. e.g. ports, volumes,... |
| created: False if the VIM element is not created by other actions, and it should not be deleted |
| vim_status: VIM status of the element. Stored also at database in the instance_XXX |
| vim_info: Detailed information of a vm/net from the VIM. Stored at database in the instance_XXX but not at |
| vim_wim_actions |
| M depends: dict with task_index(from depends_on) to dependency task |
| M params: same as extra[params] |
| MD error_msg: descriptive text upon an error.Stored also at database instance_XXX |
| MD created_at: task creation time. The task of creation must be the oldest |
| MD modified_at: next time task need to be processed. For example, for a refresh, it contain next time refresh must |
| be done |
| MD related: All the tasks over the same VIM element have same "related". Note that other VIMs can contain the |
| same value of related, but this thread only process those task of one VIM. Also related can be the |
| same among several NS os isntance-scenarios |
| MD worker: Used to lock in case of several thread workers. |
