WCS can be used in Docker with official Docker image since build 5.2.458

Docker deployment example

To deploy the simple WebRTC streaming server in Docker, do the followin steps:

1. Pull the latest WCS image from Docker Hub

sudo docker pull flashphonerofficial/webcallserver

2. Set up docker bridge network

sudo docker network create \
 --subnet 192.168.1.1/24 \
 --gateway=192.166.1.1 \
 --driver=bridge \
 --opt com.docker.network.bridge.name=br-testnet testnet

3. Start WCS docker container with your own trial or commercial license number

docker run \
-e PASSWORD=password \
-e LICENSE=license_number \
-e LOCAL_IP=192.168.1.10 \
--net testnet --ip 192.168.1.10 \
--name wcs-docker-test --rm -d flashphonerofficial/webcallserver:latest

4. Check if the container available by SSH

ssh root@192.168.1.10

5. Open Two Way Streaming example in local browser, publish a stream

6. Close the page, stop the container

sudo docker stop wcs-docker-test

Docker container configuration

Networking issues

By default, IP address will be set dynamically to the container. So if you suppose to use fixed IP address, you should set it with docker run options and pass to the container using LOCAL_IP variable:

docker run -e LICENSE=license_number -e PASSWORD=secret \
 -e LOCAL_IP=static_ip \
 --net your-docker-network \
 --ip static_ip \
 --name webcallserver-instance -d webcallserver:latest

If your docker host is behind NAT, and your WCS is supposed to be available from outside, you should set external IP address to EXTERNAL_IP variable:

docker run -e LICENSE=license_number -e PASSWORD=secret \
 -e LOCAL_IP=static_ip \
 -e EXTERNAL_IP=external_ip \
 --net your-docker-network \
 --ip static_ip \
 --name webcallserver-instance -d webcallserver:latest

Environment variables reference

The following environment variables can be passed to the container:

  • PASSWORD - SSH password to access the container. If this variable is not defined, container will not be accessible by SSH using password
  • LICENSE - Web Call Server license number. If this variable is not defined, license can be entered on first web interface logon
  • LOCAL_IP - local IP address to set to ip_local parameter in flashphoner.properties configuration file. If this variable is not defined, container IP address will be detected automatically.
  • EXTERNAL_IP - external IP address to set to ip parameter in flashphoner.properties configuration file. If this variable is not defined and LOCAL_IP is not defined, external IP address will be detected automatically.
  • CDN_ROLE - container role in CDN. If this variable is not defined, container will act as standalone server
  • CDN_ENTRY_POINT - CDN entry point server address for the container. If this variable is not defined, CDN entry point will not be set
  • CDN_GROUPS - CDN groups to which the container should belong. If this variable is not defined, the container will not belong to any CDN group

Volumes reference

The following docker volumes can be mounted to the container

  • /conf - additional configuration files folder. This volume can be mounted as read-only
  • /usr/local/FlashphonerWebCallServer/hls - HLS segments folder. This volume must be mounted with write access
  • /usr/local/FlashphonerWebCallServer/logs - logging folder. This volume must be mounted with write access
  • /usr/local/FlashphonerWebCallServer/media - media files for VOD playback folder. This volume can be mounted as read-only. This volume can be shared with another Web Call Server instances
  • /usr/local/FlashphonerWebCallServer/records - stream recoding files folder. This volume must be mounted with write access. This volume can be shared with another Web Call Server instances

The container launch example with all the volumes mounted:

docker run -e LICENSE=license_number -e CDN_ROLE=origin \
 -v /opt/wcs/conf:/conf \
 -v /opt/wcs/logs:/usr/local/FlashphonerWebCallServer/logs \
 -v /opt/wcs/hls:/usr/local/FlashphonerWebCallServer/hls \
 -v /opt/wcs/media:/usr/local/FlashphonerWebCallServer/media \
 -v /opt/wcs/records:/usr/local/FlashphonerWebCallServer/records \
 --name webcallserver-instance -d webcallserver:latest

Additional instance configuration

The following additional configuration files can be placed to the host folder mounted as /conf volume:

  • id_rsa.pub - public SSH access key. If this file is found during the container start, the container will be accessible with corresponding private key. Otherwise, if PASSWORD variable is defined, the container will be accesible by password. If neiher key, nor password are defined, SSH daemon will not be started.
  • flashphoner.properties - main server configuration file. It can be used for detailed Web Call Server instance configuration
  • wcs-core.properties - Java configuration file. It can be used for memory tuning and JMC connection configuration
  • log4j.properties - logging configuration file
  • wss.jks - SSL certificates key storage file. This file can be prepared with keytool
  • cdn_profiles.yml - CDN transcoding profiles configuration file
  • database.yml - user accounts and REST hook applications configuration
  • *.sdp - SDP settings files

All those files can be used for example to restore Web Call Server instance configuration from backup and automatic deployment. The files will be copied to the container 'as is', except flashphoner.properties:

  • ip and ip_local parameters will be changed (see IP_LOCAL variable description above)
  • if CDN_ROLE variable is set, but the file contains no CDN settings, the default settings will be added

Container ports

The following ports are available by default:

  • 22/tcp - SSH (this port is active only if password or key access is set)
  • 554/tcp - RTSP server port
  • 1935/tcp - RTMP server port
  • 1935/udp - RTMFP server port
  • 2001/tcp - server CLI port
  • 7777/tcp - server monitoring port
  • 8080-8084/tcp - WS, HTTP, CDN ports
  • 8443-8445/tcp - WSS, HTTPS ports
  • 8888/tcp - HTTPS port (for older versions compatibility)
  • 9091/tcp - HTTP port (for older versions compatibility)
  • 30000-35000/tcp - TCP media ports
  • 30000-35000/udp - UDP media ports
  • 50999/tcp - JMX port

The ports can be changed using docker run --expose parameters if necessary. In this case, the actual port values should be set to flashphoner.properties and wcs-core.properties files, see description above
