Pre-requisites
Build environment
- Maven 3.6.3
- OpenJDK 11 (11.0.8+)
- Docker (20.10+)
- docker-compose (1.25.4+)
Multicast Controller and rec.client
- Docker (20.10+)
- docker-compose (1.25.4+)
Hardware Server
- OpenJDK 11 (11.0.8+)
rec.web (recommended only for testing locally)
- Docker (20.10+)
- docker-compose (1.25.4+)
Preparation steps
First checkout the project from github:
$ git clone https://github.com/linkareti/rec-project.git
(FIXME) Then we need to switch to jdk11-migration branch:
$ git checkout jdk11-migration
To create a pendulum experiment, the script create_pendulum_experiment.sh helps to create a base experiment for a brand new pendulum
experiments/create_pendulum_experiment.sh
Mandatory arguments: * 1st argument: Name of the experiment (e.g. worldpendulum) * 2nd argument: ID of the experiment (e.g. ELAB_WORLD_PENDULUM) * 3rd argument: Pendulum location (e.g. Faro)
Optional arguments: * 4th argument: URL to the video (e.g. rtsp://elabmc.ist.utl.pt:80/wp_ccalg.sdp) * 5th argument: Pendulum serial device location (default: /dev/ttyS0)
Sample script execution to create pendulum:
$ ./create_pendulum_experiment.sh wpalentejo ELAB_WP_ALENTEJO Alentejo rtsp://elabmc.ist.utl.pt:80/wp_alentejo.sdp /dev/ttyS0
Build
Configure the following properties based on your environment:
build_pendulum.properties:
- pendulum.experiment.list: Name of the experiment(s) to build, comma (,) delimited.
- pendulum.multicast.controller.host: Hostname where Multicast controller is going to be installed (default: elab-multicast)
- pendulum.multicast.controller.port: Listen CORBA port used to recieve connections from Hardware Server, rec.web and rec.client (default: 9001)
- pendulum.rec.multicastcontroller.jmxremote.port: Listen JMX port used to recieve connections from rec.web (default: 25001)
- install.dir: Base directory where Multicast Controller is going to be installed (default: /home/elab)
- deployment.subdir: Sub directory where Multicast Controller is going to be installed (default: /rec-deployment)
docker-compose-pendulum.yml:
- WEBSWING_PUBLIC_URL: URL where webswing is accessible (e.g. https://elab-dev.vps.tecnico.ulisboa.pt/)
Package everything:
$ mvn clean package -Dmaven.test.skip=true -Djarsigner.alias="REC" -Dbuild.environment=pendulum -Dpack.docker.images
Copy resulting packages to destination servers:
- Multicast Server
$ scp deployment/images/target/*.tar multicast-server-name:/tmp/ $ scp deployment/compose/target/docker-compose-{pendulum,template}.yml multicast-server-name:/tmp/
- Hardware Server
$ scp dist/java/*HardwareServer*.zip hardware-server-name:/tmp/
Install
ReC Client and Multicast Controller
- Create user elab
$ sudo useradd --create-home --shell /bin/false --expiredate 1 elab
- Add user to docker group
$ sudo usermod -a -G docker elab
- Load ReC client image
$ sudo -u elab docker load --input /tmp/webswing.tar
- Load Multicast Controller image
$ sudo -u elab docker load --input /tmp/multicast.tar
- Load ReC client admin console image
$ sudo -u elab docker load --input /tmp/webswing-admin.tar
- Load Reverse Proxy image
$ sudo -u elab docker load --input /tmp/reverse-proxy.tar
- Copy docker-compose-template.yml and docker-compose-pendulum.yml to elab user home
$ sudo -u elab cp /tmp/docker-compose-{pendulum,template}.yml /home/elab/
- Start ReC client, ReC client Administration Console, ReC Multicast Controller and Reverse Proxy
$ sudo -u elab docker-compose -f /home/elab/docker-compose-template.yml -f /home/elab/docker-compose-pendulum.yml up -d
Hardware Server
- Replace wpexperiment with your experiment name
$ export experiment=wpexperiment
- Create user elab
$ sudo useradd --create-home --shell /bin/false --expiredate 1 elab
- Create experiment directory
$ sudo -u elab mkdir /home/elab/rec-deployment/${experiment}
- Unpack experiment package to experiment directory
$ sudo -u elab unzip /tmp/${experiment}HardwareServer*.zip -d /home/elab/rec-deployment/${experiment}
- Start experiment
$ sudo -u elab /home/elab/rec-deployment/${experiment}/${experiment}Daemon.sh start
