Clustered configuration
Running ./start.sh will perform some cleanup then start the containers in a clustered configuration.
When running, the system looks like this:
+--------------------------------------------------+
| 172.60.0.99 |

| | |+--------------+ |

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.examplexmpp2.localhost.examplexmpp3.localhost.example
The following users are configured:
user1passworduser2password
The following MUC rooms are configured:
muc1muc2
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 |
| +------------+ |

| | | |

| 172.60.0.111 |
| |
+------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:
user1passworduser2password
The following MUC rooms are configured:
muc1muc2
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.
When the -6 argument to ./start.sh is provided, then an additional subnet of fd23:0d79:d076::/64 is configured.
Then, IPv6 is preferred for internal networking. Note that the IPv4 network remains in place, as Docker does not support
IPv6-only containers.
When running with the optional -6 flag (that adds IPv6 support) the system looks like this:
+--------------------------------------------------+

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
For example:
docker network connect openfire-testing_openfire-federated-net openfire-testing_xmpp1_1
