Update

Update an existing sysctl parameter on a target host. The value is rewritten to /etc/sysctl.d/osapi-{key}.conf and applied immediately via sysctl -p. Fails if the key is not currently managed -- use create first:

$ osapi client node sysctl update --target web-01 \
    --key net.ipv4.ip_forward --value 0

  Job ID: 550e8400-e29b-41d4-a716-446655440000

  KEY                   CHANGED
  net.ipv4.ip_forward   true

If the parameter already has the requested value, changed: false is returned and the file is not rewritten:

$ osapi client node sysctl update --target web-01 \
    --key net.ipv4.ip_forward --value 0

  Job ID: 550e8400-e29b-41d4-a716-446655440000

  KEY                   CHANGED
  net.ipv4.ip_forward   false

Broadcast to all hosts at once:

$ osapi client node sysctl update --target _all \
    --key vm.swappiness --value 20

  Job ID: 550e8400-e29b-41d4-a716-446655440000

  HOSTNAME  KEY           CHANGED
  web-01    vm.swappiness  true
  web-02    vm.swappiness  true

JSON Output

Use --json to get the full API response:

$ osapi client node sysctl update --target web-01 \
    --key vm.swappiness --value 20 --json
{"results":[{"hostname":"web-01","key":"vm.swappiness","changed":true,"status":"ok"}],"job_id":"..."}
