config-auto-healing

Description

Configure auto-healing for a VKS cluster. Auto-healing automatically replaces unhealthy nodes to keep the cluster in a working state.

Synopsis

grn vks config-auto-healing
    --cluster-id <value>
    --enable-auto-healing
    [--max-unhealthy <value>]
    [--unhealthy-range <value>]
    [--timeout-unhealthy <value>]

Options

--cluster-id (required) : The ID of the cluster.

--enable-auto-healing (required) : Whether to enable auto-healing. Pass --enable-auto-healing to enable, or --enable-auto-healing=false to disable.

--max-unhealthy (optional) : Maximum number (or percentage) of unhealthy nodes tolerated, e.g. 30%.

--unhealthy-range (optional) : The unhealthy range threshold.

--timeout-unhealthy (optional) : Time in seconds a node may stay unhealthy before it is replaced.

Examples

Enable auto-healing with default thresholds:

grn vks config-auto-healing \
  --cluster-id cls-abc12345-6789-def0-1234-abcdef012345 \
  --enable-auto-healing

Enable auto-healing with custom thresholds:

grn vks config-auto-healing \
  --cluster-id cls-abc12345-6789-def0-1234-abcdef012345 \
  --enable-auto-healing \
  --max-unhealthy 30% \
  --timeout-unhealthy 300

Disable auto-healing:

grn vks config-auto-healing \
  --cluster-id cls-abc12345-6789-def0-1234-abcdef012345 \
  --enable-auto-healing=false
