Docker

It is suggested to be familiar with the various kinds of roles for the on-premise deployment.

1. Hardware required for Docker Swarm

Below is the list of hardware required that you will need to provision.

Minimum CPU	Minimum RAM	Minimum Storage	Requires Public IP	VM	Open Public Ports
master	8 core	32GB	250GB	Yes	TCP: 80,443
storage1	8 core	32GB	250GB	No
storage2	8 core	32GB	250GB	No
calling	8 core	32GB	50GB	Yes	TCP: 80,443, 10000-20000 UDP: 10000-20000
websocket	8 core	32GB	50GB	Yes	TCP: 80,443,7070,5222,5223
node1	4 core	8GB	50GB	No
node2	4 core	8GB	50GB	No
extensions	4 core	8GB	50GB	Yes	TCP: 80, 443

2. Once the hardware and public IP’s are ready

Please inform us of the IP’s so that we can complete the required DNS record changes and configurations.

Ensure that the machines can connect to one another.

3. Install docker, docker compose are installed on all machines

Ensure that a recent docker (version 3.7) with docker-compose is installed on all machines.

4. Download the On-Prem shared by CometChat

Which will be shared with you.

5. Begin bootstrapping master

This will be shared with you, and restricts the deployment by number. of attempts, the IP’s , your customer metadata, billing and renewal with CometChat Pro.

cd cometchatpro-onprem-dockerswarm-1.0.0
._master_bootstrap.sh

Expected Logs

Step 1: Please paste the CometChat Pro On-Premise Token shared with you                                                           
Password:                                                                                                                        
Login Succeeded                                                                                                                   
Step 2: Starting Docker Swarm for CometChat Pro On-Premise
Swarm initialized: current node (....) is now a manager.

To add a worker to this swarm, run the following command:

    docker swarm join --token ...

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

Step 3: Please run the above from node1 and node2

You are now ready to bootstrap the other machines. Once they are all bootstrapped, we will come back to master to complete the bootstrap.

6. Bootstrapping other machines

Docker, docker-compose and the CometChat Folder must be available.

# see step2 of bootstrap master
docker swarm join...

cd cometchatpro-onprem-dockerswarm-1.0.0

#on calling
._calling_bootstrap.sh

#on websocket
._calling_bootstrap.sh

#on node1, node2
._node_bootstrap.sh

#on extensions
._extensions_bootstrap.sh
