Salt Master Events

These events are fired on the Salt Master event bus. This list is not comprehensive.

Authentication events

salt/auth

Fired when a minion performs an authentication check with the master.

变量:
  • id -- The minion ID.
  • act -- The current status of the minion key: accept, pend, reject.
  • pub -- The minion public key.

注解

Minions fire auth events on fairly regular basis for a number of reasons. Writing reactors to respond to events through the auth cycle can lead to infinite reactor event loops (minion tries to auth, reactor responds by doing something that generates another auth event, minion sends auth event, etc.). Consider reacting to salt/key or salt/minion/<MID>/start or firing a custom event tag instead.

Start events

salt/minion/<MID>/start

Fired every time a minion connects to the Salt master.

变量:id -- The minion ID.

Key events

salt/key

Fired when accepting and rejecting minions keys on the Salt master.

变量:
  • id -- The minion ID.
  • act -- The new status of the minion key: accept, pend, reject.

警告

If a master is in auto_accept mode, salt/key events will not be fired when the keys are accepted. In addition, pre-seeding keys (like happens through Salt-Cloud) will not cause firing of these events.

Job events

salt/job/<JID>/new

Fired as a new job is sent out to minions.

变量:
  • jid -- The job ID.
  • tgt -- The target of the job: *, a minion ID, G@os_family:RedHat, etc.
  • tgt_type -- The type of targeting used: glob, grain, compound, etc.
  • fun -- The function to run on minions: test.ping, network.interfaces, etc.
  • arg -- A list of arguments to pass to the function that will be called.
  • minions -- A list of minion IDs that Salt expects will return data for this job.
  • user -- The name of the user that ran the command as defined in Salt's Publisher ACL or external auth.
salt/job/<JID>/ret/<MID>

Fired each time a minion returns data for a job.

变量:
  • id -- The minion ID.
  • jid -- The job ID.
  • retcode -- The return code for the job.
  • fun -- The function the minion ran. E.g., test.ping.
  • return -- The data returned from the execution module.
salt/job/<JID>/prog/<MID>/<RUN NUM>

Fired each time a each function in a state run completes execution. Must be enabled using the state_events option.

变量:
  • data -- The data returned from the state module function.
  • id -- The minion ID.
  • jid -- The job ID.

Presence events

salt/presence/present

Events fired on a regular interval about currently connected, newly connected, or recently disconnected minions. Requires the presence_events setting to be enabled.

变量:present -- A list of minions that are currently connected to the Salt master.
salt/presence/change

Fired when the Presence system detects new minions connect or disconnect.

变量:
  • new -- A list of minions that have connected since the last presence event.
  • lost -- A list of minions that have disconnected since the last presence event.

Cloud Events

Unlike other Master events, salt-cloud events are not fired on behalf of a Salt Minion. Instead, salt-cloud events are fired on behalf of a VM. This is because the minion-to-be may not yet exist to fire events to or also may have been destroyed.

This behavior is reflected by the name variable in the event data for salt-cloud events as compared to the id variable for Salt Minion-triggered events.

salt/cloud/<VM NAME>/creating

Fired when salt-cloud starts the VM creation process.

变量:
  • name -- the name of the VM being created.
  • event -- description of the event.
  • provider -- the cloud provider of the VM being created.
  • profile -- the cloud profile for the VM being created.
salt/cloud/<VM NAME>/deploying

Fired when the VM is available and salt-cloud begins deploying Salt to the new VM.

变量:
  • name -- the name of the VM being created.
  • event -- description of the event.
  • kwargs -- options available as the deploy script is invoked: conf_file, deploy_command, display_ssh_output, host, keep_tmp, key_filename, make_minion, minion_conf, name, parallel, preseed_minion_keys, script, script_args, script_env, sock_dir, start_action, sudo, tmp_dir, tty, username
salt/cloud/<VM NAME>/requesting

Fired when salt-cloud sends the request to create a new VM.

变量:
  • event -- description of the event.
  • location -- the location of the VM being requested.
  • kwargs -- options available as the VM is being requested: Action, ImageId, InstanceType, KeyName, MaxCount, MinCount, SecurityGroup.1
salt/cloud/<VM NAME>/querying

Fired when salt-cloud queries data for a new instance.

变量:
  • event -- description of the event.
  • instance_id -- the ID of the new VM.
salt/cloud/<VM NAME>/tagging

Fired when salt-cloud tags a new instance.

变量:
  • event -- description of the event.
  • tags -- tags being set on the new instance.
salt/cloud/<VM NAME>/waiting_for_ssh

Fired while the salt-cloud deploy process is waiting for ssh to become available on the new instance.

变量:
  • event -- description of the event.
  • ip_address -- IP address of the new instance.
salt/cloud/<VM NAME>/deploy_script

Fired once the deploy script is finished.

变量:event -- description of the event.
salt/cloud/<VM NAME>/created

Fired once the new instance has been fully created.

变量:
  • name -- the name of the VM being created.
  • event -- description of the event.
  • instance_id -- the ID of the new instance.
  • provider -- the cloud provider of the VM being created.
  • profile -- the cloud profile for the VM being created.
salt/cloud/<VM NAME>/destroying

Fired when salt-cloud requests the destruction of an instance.

变量:
  • name -- the name of the VM being created.
  • event -- description of the event.
  • instance_id -- the ID of the new instance.
salt/cloud/<VM NAME>/destroyed

Fired when an instance has been destroyed.

变量:
  • name -- the name of the VM being created.
  • event -- description of the event.
  • instance_id -- the ID of the new instance.
