Sequentially recreating instances in a group

If you do not have the Yandex Cloud CLI yet, install and initialize it.

The folder used by default is the one specified when creating the CLI profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also specify a different folder for any command using --folder-name or --folder-id. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

1. See the description of the CLI command for recreating an instance group:

   yc compute instance-group rolling-recreate --help
   

2. Get a list of folders in the default cloud:

   yc resource-manager folder list
   

   Result:

   +----------------------+--------------------+------------------+--------+
   |          ID          |        NAME        |      LABELS      | STATUS |
   +----------------------+--------------------+------------------+--------+
   | b1gd129pp9ha******** | my-folder          |                  | ACTIVE |
   | b1g66mft1vop******** | default            |                  | ACTIVE |
   +----------------------+--------------------+------------------+--------+
   

3. Get a list of instance groups in the selected folder by specifying its name:

   yc compute instance-group list \
     --folder-name <folder_name>
   

   Result:

   +----------------------+-----------------------+--------+------+
   |          ID          |         NAME          | STATUS | SIZE |
   +----------------------+-----------------------+--------+------+
   | amc65sbgfqeq******** | first-instance-group  | ACTIVE |    4 |
   +----------------------+-----------------------+--------+------+
   

4. Recreate VM instances in the instance group:

   yc compute instance-group rolling-recreate --all \
     --name <instance_group_name> \
     --folder-name <folder_name>
   

   Where:

   • --name: Instance group name.
   • --folder-name: Name of the folder the instance group belongs to.

   Instance Groups will start recreating all instances in the group one by one. The recreated instances will change their status to Running.

   Result:

   done (2m43s)
   id: amc65sbgfqeq********
   ...
   status: ACTIVE
   application_load_balancer_state: {}
   

   To recreate individual instances in a group, get a list of instances in that group:

   yc compute instance-group list-instances \
     --name <instance_group_name> \
     --folder-name <folder_name>
   

   Where:

   • --name: Instance group name.
   • --folder-name: Name of the folder the instance group belongs to.

   Result:

   +----------------------+---------------------------+----------------+--------------+------------------------+----------------+
   |     INSTANCE ID      |           NAME            |  EXTERNAL IP   | INTERNAL IP  |         STATUS         | STATUS MESSAGE |
   +----------------------+---------------------------+----------------+--------------+------------------------+----------------+
   | epdl7gdvb69f******** | cl17k72ehu54********-amyk | 130.193.**.*** | 192.168.0.33 | RUNNING_ACTUAL [8m]    |                |
   | epdjtb04efcf******** | cl17k72ehu54********-oper | 84.201.***.*** | 192.168.0.17 | RUNNING_ACTUAL [6m]    |                |
   | epd3anghn4vb******** | cl17k72ehu54********-axec | 84.201.***.*** | 192.168.0.14 | RUNNING_ACTUAL [1m50s] |                |
   | epdbt0c7o6d3******** | cl17k72ehu54********-ihez | 51.250.***.*** | 192.168.0.29 | RUNNING_ACTUAL [1m0s]  |                |
   +----------------------+---------------------------+----------------+--------------+------------------------+----------------+
   

   Recreate the VM instances in question:

   yc compute instance-group rolling-recreate \
     --instance-ids <VM_instance_IDs> \
     --name <instance_group_name> \
     --folder-name <folder_name>
   

   Where:

   • --instance-ids: Comma-separated IDs of instances to recreate. For example, to recreate the first and third instances from those listed, specify --instance-ids epdl7gdvb69f********,epd3anghn4vb********.
   • --name: Instance group name.
   • --folder-name: Name of the folder the instance group belongs to.

   Instance Groups will start recreating the specified instances in the group one by one. The recreated instances will change their status to Running.
