10. Docker or Kubernetes?
• Docker is about containerization
• Kubernetes is about orchestrating containers.
Docker containers are the building blocks. A small deployment has a minimum
number of containers to create a solution that allows users to collaborate, but
without scalability, load balancing, etc. If you are deploying for a small group
and do not require scalability.
Kubernetes builds on base containers and allows them to scale automatically;
load balancing between multiple physical or virtual hosts.
• The dock can support up to 200 concurrent users. Meeting records are CPU
intensive. A Docker instance can record a maximum of 2 appointments at a
time!

What is Docker?
Docker is an open-source lightweight containerization technology. It allows you to
automate the deployment of applications in lightweight and portable containers and
ship it all out as one package. It also allows you to run multiple Operating systems on
the same host.

Additional configuration options
57

59. HCL Sametime Meetings – Additional configuration options
Configuration files for Docker:
.env
• Guest access
• STUN server configuration
• SIP configuration settings for Dial out
• Single Sign On
• Meeting Server Timezone
custom.env
• Information about the Sametime Proxy server
• Docker Host Address
• MongoDB Connection
• IDP URL
• Days Recordings remain on server
• Meeting server Fully Qualified Hostname 58

60. HCL Sametime Meetings – Additional configuration options
• How to enable "host" access to the Meetings server (default enabled):
- in polices.user.xml enable in the „anonymous“ section im.meetingsEnabled=1
- in file .env enable ENABLE_GUESTS=1 (0 disable)
• How o change Time zone Meetings server
- on file .env change
# System time zone.
TZ=Europe/Prague (for example)
• How to enable meeting recording and meeting recording retention time
- in file .env for enable ENABLE_RECORDING=1
- in file custom.env set the number of days in the line EXPIRES_IN_DAYS=number of day (default 3)
• How to limit the maximum number of meeting participants:
- in the docker-compose.yml file : MAX_OCCUPANTS=počet
Currently, the maximum number of users supported per meeting is 50..
59

61. HCL Sametime Meetings – Additional configuration options
New: TCP instead of UDP for audio and video streams
By default, Sametime 11.5 Meetings only supports UDP for audio and video.
When streaming audio and video, UDP has a performance advantage over TCP because of the overhead
that is part of the TCP protocol than UDP. UDP transmits small bits of data transfer is relatively faster
than TCP. UDP is recommended for best performance.
There are situations where users cannot use UDP and therefore Meetings do not work properly for them.
The Sametime Meetings server can be configured to stream media over TCP.
60

62. HCL Sametime Meetings – TCP instead of UDP for A/V streams
Use these settings to enable both UDP and TCP
The client tries UDP first, and if it fails, TCP is used.
• Open .env file, find configuration „JVB_TCP_HARVESTER_DISABLED“and change the value to false :
JVB_TCP_HARVESTER_DISABLED = false
• In .env file find the item for the field JVB_TCP_PORT.
Remove # comments
JVB_TCP_PORT = 4443
• Open docker-compose.yaml file. Add the JVB_TCP_PORT section for the JVB component:
# Video most
jvb:
ports:
- '$ {JVB_PORT}: $ {JVB_PORT} / udp'
- '$ {JVB_TCP_PORT}: $ {JVB_TCP_PORT}'
61

63. HCL Sametime Meetings – TCP instead of UDP for A/V streams
Use these settings to enable only TCP
• Open .env file, find configuration „JVB_TCP_HARVESTER_DISABLED“and change the value to false :
JVB_TCP_HARVESTER_DISABLED = false
• In .env file find the item for the field JVB_TCP_PORT.
Remove # comments
JVB_TCP_PORT = 4443
• Open docker-compose.yaml file. Add the JVB_TCP_PORT section for the JVB component:
# Video bridge
jvb:
ports:
# - '$ {JVB_PORT}: $ {JVB_PORT} / udp'
- '$ {JVB_TCP_PORT}: $ {JVB_TCP_PORT}'
62

64. Step 9
Problem solving
63

65. HCL Sametime Meetings – problem solving
• Audio and video do not work
- check your firewall to see if you have bidirectionally enabled UDP port 10000 for
Google STUN servers: stun.l.google.com:19302,stun1.l.google.com:19302,stun2.l.google.com:19302
Why STUN: Simply put, STUN is a tool that helps to determine the public IP address of individual meeting
participants and to be able to connect to each other. However, not everyone has a public IP address.
When you try to join a meeting, you only see: "Loading meeting ..."
- check IP address DOCKER_HOST_ADDRESS - in .env file
• You need to reinstall the Meeting server or make a configuration change
- always remember to delete the directory ./jitsi-config
