salt.modules.swarm.joinswarm(remote_addr=<class 'int'>, listen_addr=<class 'int'>, token=<class 'str'>)

Join a Swarm Worker to the cluster

remote_addr

The manager node you want to connect to for the swarm

listen_addr

Listen address used for inter-manager communication if the node gets promoted to manager, as well as determining the networking interface used for the VXLAN Tunnel Endpoint (VTEP)

token

Either the manager join token or the worker join token. You can get the worker or manager token via salt '*' swarm.swarm_tokens

CLI Example:

salt '*' swarm.joinswarm remote_addr=192.168.50.10 listen_addr='0.0.0.0'             token='SWMTKN-1-64tux2g0701r84ofq93zppcih0pe081akq45owe9ts61f30x4t-06trjugdu7x2z47j938s54il'

salt.modules.swarm.leave_swarm(force=<class 'bool'>)

Force the minion to leave the swarm

force

Will force the minion/worker/manager to leave the swarm

CLI Example:

salt '*' swarm.leave_swarm force=False

salt.modules.swarm.node_ls(server=<class 'str'>)

Displays Information about Swarm Nodes with passing in the server

server

The minion/server name

CLI Example:

salt '*' swarm.node_ls server=minion1

salt.modules.swarm.remove_node(node_id=<class 'str'>, force=<class 'bool'>)

Remove a node from a swarm and the target needs to be a swarm manager

node_id

The node id from the return of swarm.node_ls

force

Forcefully remove the node/minion from the service

CLI Example:

salt '*' swarm.remove_node node_id=z4gjbe9rwmqahc2a91snvolm5 force=false

salt.modules.swarm.remove_service(service=<class 'str'>)

Remove Swarm Service

service

The name of the service

CLI Example:

salt '*' swarm.remove_service service=Test_Service

salt.modules.swarm.service_create(image=<class 'str'>, name=<class 'str'>, command=<class 'str'>, hostname=<class 'str'>, replicas=<class 'int'>, target_port=<class 'int'>, published_port=<class 'int'>)

Create Docker Swarm Service Create

image

The docker image

name

Is the service name

command

The docker command to run in the container at launch

hostname

The hostname of the containers

replicas

How many replicas you want running in the swarm

target_port

The target port on the container

published_port

port thats published on the host/os

CLI Example:

salt '*' swarm.service_create image=httpd name=Test_Service             command=None hostname=salthttpd replicas=6 target_port=80 published_port=80

salt.modules.swarm.swarm_init(advertise_addr=<class 'str'>, listen_addr=<class 'int'>, force_new_cluster=<class 'bool'>)

Initalize Docker on Minion as a Swarm Manager

advertise_addr

The ip of the manager

listen_addr

Listen address used for inter-manager communication, as well as determining the networking interface used for the VXLAN Tunnel Endpoint (VTEP). This can either be an address/port combination in the form 192.168.1.1:4567, or an interface followed by a port number, like eth0:4567

force_new_cluster

Force a new cluster if True is passed

CLI Example:

salt '*' swarm.swarm_init advertise_addr='192.168.50.10' listen_addr='0.0.0.0' force_new_cluster=False

salt.modules.swarm.swarm_service_info(service_name=<class 'str'>)

Swarm Service Information

service_name

The name of the service that you want information on about the service

CLI Example:

salt '*' swarm.swarm_service_info service_name=Test_Service

salt.modules.swarm.swarm_tokens()

Get the Docker Swarm Manager or Worker join tokens

CLI Example:

salt '*' swarm.swarm_tokens

salt.modules.swarm.update_node(availability=<class 'str'>, node_name=<class 'str'>, role=<class 'str'>, node_id=<class 'str'>, version=<class 'int'>)
