Application Commands and Helm OverridesΒΆ

Use StarlingX system application and system helm-override commands to manage containerized applications provided as part of StarlingX.

Procedure

  • Use the following command to list all containerized applications provided as part of StarlingX.

    ~(keystone_admin)]$ system application-list [--nowrap]
    

    where:

    nowrap

    Prevents line wrapping of the output.

    For example:

    ~(keystone_admin)]$ system application-list --nowrap
    
    +-------------+---------+---------------+---------------+----------+-----------+
    | application | version | manifest name | manifest file | status   | progress  |
    +-------------+---------+---------------+---------------+----------+-----------+
    | platform-   | 1.0-7   | platform-     | manifest.yaml | applied  | completed |

  • To show the overrides for a particular chart, use the following command. System overrides are displayed in the system_overrides section of the Property column.

    ~(keystone_admin)]$ system helm-override-show
    usage: system helm-override-show <app_name> <chart_name> <namespace>
    

    where the following are positional arguments:

    <app_name>

    The name of the application.

    < chart_name>

    The name of the chart.

    <namespace>

    The namespace for chart overrides.

    For example:

    ~(keystone_admin)]$ system helm-override-show stx-openstack glance openstack
    
  • To modify service configuration parameters using user-specified overrides, use the following command. To update a single configuration parameter, you can use --set. To update multiple configuration parameters, use the --values option with a yaml file.

    ~(keystone_admin)]$ system helm-override-update
    usage: system helm-override-update <app_name> <chart_name> <namespace> --reuse-values --reset-values --values <file_name> --set <commandline_overrides>
    

    where the following are positional arguments:

    <app_name>

    The name of the application.

    <chart_name>

    The name of the chart.

    <namespace>

    The namespace for chart overrides.

    and the following are optional arguments:

    reuse-values

    Reuse existing Helm chart user override values. This argument is ignored if reset-values is used.

    reset-values

    Replace any existing Helm chart overrides with the ones specified.

    values

    Specify a yaml file containing Helm chart override values. You can specify this value multiple times.

    set

    Set Helm chart override values using the command line. Multiple override values can be specified with multiple set arguments. These are processed after files passed through the values argument.

    For example, to enable the glance debugging log, use the following command:

    ~(keystone_admin)]$ system helm-override-update stx-openstack glance openstack --set conf.glance.DEFAULT.DEBUG=true
    +----------------+-------------------+
    | Property       | Value             |
    +----------------+-------------------+
    | name           | glance            |
    | namespace      | openstack         |
    | user_overrides | conf:             |
    |                |   glance:         |
    |                |     DEFAULT:      |
    |                |       DEBUG: true |
    +----------------+-------------------+
    

    The user overrides are shown in the user_overrides section of the Property column.

    Note

    To apply the updated Helm chart overrides to the running application, use the system application-apply command.

  • To enable or disable the installation of a particular Helm chart within an application manifest, use the helm-chart-attribute-modify command. This command does not modify a chart or modify chart overrides, which are managed through the helm-override-update command.

    ~(keystone_admin)]$ system helm-chart-attribute-modify [--enabled <true/false>] <app_name> <chart_name> <namespace>
    

    where the following is an optional argument:

    The name of the application.

    <chart_name>

    The name of the chart.

    <namespace>

    The namespace for chart overrides.

    Note

    To apply the updated Helm chart attribute to the running application, use the system application-apply command.

  • To delete all the user overrides for a chart, use the following command:

    ~(keystone_admin)]$ system helm-override-delete
    usage: system helm-override-delete <app_name> <chart_name> <namespace>
    

    where the following are positional arguments:

    <app_name>

    The name of the application.

    <chart_name>

    The name of the chart.

    <namespace>

    The namespace for chart overrides.

    For example:

    ~(keystone_admin)]$ system helm-override-delete stx-openstack glance openstack
    Deleted chart overrides glance:openstack for application stx-openstack
    
  • Use the following command to apply or reapply an application, making it available for service.

    ~(keystone_admin)]$ system application-apply [-m | --mode] <mode> <app_name>
    

    where the following is an optional argument:

    mode

    An application-specific mode controlling how the manifest is applied. This option is used to delete and restore the stx-openstack application.

    and the following is a positional argument:

    <app_name>

    The name of the application to apply.

    For example:

    ~(keystone_admin)]$ system application-apply stx-openstack

    | progress      | None                             |
    | status        | applying                         |

    Please use 'system application-list' or 'system application-show
    stx-openstack' to view the current progress.
    
  • Use the following command to abort the current application.

    ~(keystone_admin)]$ system application-abort <app_name>
    

    where:

    <app_name>

    The name of the application to abort.

    For example:

    ~(keystone_admin)]$ system application-abort stx-openstack
    Application abort request has been accepted. If the previous operation has not
    completed/failed, it will be cancelled shortly.
    

    Use application-list to confirm that the application has been aborted.

  • Use the following command to update the deployed application to a different version.

    ~(keystone_admin)]$ system application-update [-n | --app-name] <app_name> [-v | --app-version] <version> <tar_file>
    

    where the following are optional arguments:

    <app_name>

    The name of the application to update.

    You can look up the name of an application using the application-list command:

    ~(keystone_admin)]$ system application-list
    +--------------------------+----------+-------------------------------+---------------------------+----------+-----------+
    | application              | version  | manifest name                 | manifest file             | status   | progress  |

    and the following is a positional argument which must come last:

    <tar_file>

    The tar file containing the application manifest, Helm charts and configuration file.

  • Use the following command to remove an application from service. Removing an application will clean up related Kubernetes resources and delete all of its installed Helm charts.

    ~(keystone_admin)]$ system application-remove <app_name>
    

    where:

    <app_name>

    The name of the application to remove.

    For example:

    +---------------+----------------------------------+
    Please use 'system application-list' or 'system application-show
    stx-openstack' to view the current progress.
    

    This command places the application in the uploaded state.

  • Use the following command to completely delete an application from the system.

    ~(keystone_admin)]$ system application-delete <app_name>
    

    where:

    <app_name>
