collective(1) -- Check and manage a confluent collective
|
||
|
|
==============================
|
||
|
|
|
||
|
|
## SYNOPSIS
|
||
|
|
|
||
|
|
`collective invite <server>`
|
||
|
|
`collective join <server> [-i TOKEN]`
|
||
|
|
`collective show`
|
||
|
|
`collective gencert`
|
||
|
|
|
||
|
|
|
||
|
|
## DESCRIPTION
|
||
|
|
|
||
|
|
**collective** helps manage the collective mode of confluent, where multiple
|
||
|
|
confluent servers are linked together to act as one. For example, the procedure to set up
|
||
|
|
a collective to run on three servers called mgt1, mgt2, and mgt3, first install and start
|
||
|
|
confluent as usual on the three servers. On mgt1, run `collective invite mgt2` and an
|
||
|
|
invitation token will be output. On mgt2, either run `collective join mgt1` to paste
|
||
|
|
the token interactively, or `collective join mgt1 -i <token>`. At this point, either
|
||
|
|
mgt1 or mgt2 can bring in mgt3. For example on mgt2 run `collective invite mgt3` and
|
||
|
|
on mgt3 run `collective join mgt2 -i <token>`
|
||
|
|
|
||
|
|
This can be linked together in the following manner with ssh:
|
||
|
|
on mgt1:
|
||
|
|
`# ssh mgt2 collective join mgt1 -i $(collective invite mgt2)`
|
||
|
|
|
||
|
|
Note that a collective is only redundant with 3 or more members. The collective
|
||
|
|
will function so long as more than half of the members are online. A collective
|
||
|
|
of two members is supported, but without redundancy.
|
||
|
|
|
||
|
|
Also note that the collective leader role is dynamic, but has no impact on interacting
|
||
|
|
with confluent. It is merely an internal role that can dynamically change depending
|
||
|
|
on circumstances.

## OPTIONS
|
||
|
|
|
||
|
|
* `-i`:
|
||
|
|
Provide the token as an argument rather than interactively.
|
||
|
|
|
||
|
|
## EXAMPLES
|
||
|
|
* Inviting a server called mgt2:
|
||
|
|
`# collective invite mgt2`
|
||
|
|
`bWd0MkA+BNQ6XAxMXlqJJa+EQRlihL/k9xCXnasgSQXZr989Pa1/ln7G3e1Ncxx6BMzMqqreHJVkPr2FrzjNit/UgHlg`
|
||
|
|
|
||
|
|
* On mgt2, joining mgt1:
|
||
|
|
`# collective join mgt1 -i bWd0MkA+BNQ6XAxMXlqJJa+EQRlihL/k9xCXnasgSQXZr989Pa1/ln7G3e1Ncxx6BMzMqqreHJVkPr2FrzjNit/UgHlg`
|
||
|
|
`Success`
|
||
|
|
|
||
|
|
* Showing the collective state:
|
||
|
|
`# collective show`
|

|
|
`Quorum: True`
|
||
|
|
`Leader: mgt1`
|
