Clustered configuration

Running ./start.sh will perform some cleanup then start the containers in a clustered configuration. When running, the system looks like this:

Note that the load balancer is configured to be less flappy, with the flappiness controlled by the nginx config, simulating simple round-robin DNS load balancing. Ports from individual servers are exposed and can be hit directly.

Openfire is configured with the following XMPP domain:

xmpp.localhost.example

Openfire is configured with the following hostnames:

xmpp1.localhost.example
xmpp2.localhost.example
xmpp3.localhost.example

The following users are configured:

user1 password
user2 password

The following MUC rooms are configured:

muc1
muc2

The federated domain

The start script will also instantiate a second XMPP domain that consists of one Openfire server. This will result in the following components to be added to the system as described above:

                   +------------------------+
                   |       172.60.0.110     |

                   +------172.60.0.0/24-----+

The additional Openfire is configured with the following XMPP domain:

otherxmpp.localhost.example

Openfire is configured with the following hostname:

otherxmpp.localhost.example

The following users are configured:

user1 password
user2 password

The following MUC rooms are configured:

muc1
muc2

Note that users and MUC rooms on the additional Openfire domain have a similar name to those on the cluster. This does not lead to collisions, as the domain-part of their JIDs will differ.

Network

The Docker compose file defines a custom bridge network with a single subnet of 172.60.0.0/24 for the clustered configuration.

Removing a node from the network

To remove a node from the network run the following command:

docker network disconnect NETWORK-NAME CONTAINER-NAME

For example:

docker network disconnect openfire-testing_openfire-federated-net openfire-testing_xmpp1_1

Adding a node to the network

To add a node to the network fun the following command:

docker network connect NETWORK-NAME CONTAINER-NAME
