- cp simulator.tar.gz to a special folder
- unzip simulator.tar.gz
- cd simulator
- modify application.properties
...
5. run the command： java -jar simulator-0.0.1-SNAPSHOT.jar >/dev/null &
Start by docker-compose（Updated in H release）

1. Extract the downloaded cn-nssmf-simulator-docker-compose.tar.gz
tar xf cn-nssmf-simulator-docker-compose.tar.gz -C .
cd cn-nssmf-simulator-docker-compose
2. modify application.properties
# vi application.properties
server.port=11111
notifyurl=http://192.168.235.25:30472/v1/pm/notification
ftppath=sftp://root:oom@192.168.235.25:22/home/ubuntu/dcae/PM.tar.gz
fixeddelay=900000
#Configure the output files generated in docker.
filepath=/app/dcae
amffilepath=/app/dcae/AMF.xml.gz
upffilepath=/app/dcae/UPF.xml.gz
3. modify docker-compose.yml
# vi docker-compose.yml
version: '3'
services:
cn-simulator-docker-compose:
image: openjdk:8-jre-slim
container_name: cn-simulator-test-1
ports:
- "11111:11111"
restart: always
# mount the cn-nssmf-simulator-docker-compose directory of the host machine to the /app directory of the container
# If you need to modify the simulator's configuration file application.properties later,
# you can directly modify the host's cn-nssmf-simulator-docker-compose/application.properties to synchronize to the container
volumes:
- ./:/app
working_dir: /app
entrypoint: java -jar simulator-0.0.1-SNAPSHOT.jar
...
4. start up the application by running " docker-compose up "
Customize the helm charts to suit use case(from the kubernetes directory):
> rm -rf cds/charts/cds-command-executor/
> rm -rf sdc/charts/sdc-dcae-be/
> rm -rf sdc/charts/sdc-dcae-dt/
...
5. Register sndc info in AAI-ESR-GUI:
K8S='172.19.0.50' # depned on your k8s
THIRDPARTY_SDNC_ID='12345' # dont' care, anyting ok
ESR_SYSTEM_INFO_ID='12345' # dont' care, anyting ok
VENDER='HW' # only HW
TYPE='cn' # only cn
SIM_IP='172.19.0.11' # depned on your sim
