Maintenance Mode
When in maintenance mode, Cloudify Manager activity is suspended. It rejects all requests, and does not perform any action other than to display the status of the Manager and it’s version, and to execute sub-commands of the maintenance mode.
Cloudify Manager has three maintenance states, activated, activating, and deactivated. To view the current maintenance state of the Manager, run cfy maintenance-mode status
. The state is also displayed when you run cfy status
(so long as the state is not deactivated
).
- Activated
Cloudify Manager is in maintenance mode. It ignores all requests except forcfy status
,cfy --version
and sub-commands ofcfy maintenance-mode
. - Activating
An intermediate state in which the Cloudify Manager is not fully in maintenance mode. Only requests that trigger executions are blocked. This state enables active executions to complete and prevents new executions from being started. - Deactivated
Cloudify Manager operates normally. No requests are blocked.
Usage and Flow
By default, the maintenance mode state is deactivated
.
To activate maintenance mode, run cfy maintenance-mode activate
. Cloudify Manager either enters the activated
or activating
state.
To view the current status of the maintenance mode, run cfy maintenance-mode status
.
Following the activation request, if there are no active executions (running, pending, cancelling etc.), maintenance mode is activated.
The output of cfy maintenance-mode status
for the activated
state is as follows.
Maintenance Mode Status:
Status: activated
Activated At: <time of activation>
Activation Requested At: <time of activation request>
If there are active executions, the Manager enters the activating
state.
Maintenance Mode Status:
Status: activating
Activation Requested At: <time of activation request>
Cloudify Manager currently has <number of active executions> running or pending executions. Waiting for them to finish before activating.
After all executions have completed, the Manager enters the ‘activated’ state.
If you run the maintenance mode status command in verbose mode, you can view detailed information about the current active executions.
Run cfy maintenance-mode deactivate
to deactivate maintenance mode.
