Open5Gs on K8s

Deploying the core

One UPF

To deploy the core with one UPF the following parameters are required on deployment:

• amf.lbIP="THE AMF IP"
• upf.upf1IP="THE UPF IP"
• dnn.upf1="dnn1"

Two UPFs

To deploy the core with two UPFs the following parameters are required on deployment:

• amf.lbIP="THE AMF IP"
• upf.upfs="2"
• upf.upf1IP="THE FIRST UPF IP"
• upf.upf2IP="THE SECOND UPF IP"
• dnn.upf1="dnn1"
• dnn.upf2="dnn2"

Deploying the UPF

To deploy a UPF the following parameters are required on deployment:

• upf.config="1|2 (upf 1 or upf 2)"
• upf.lbIP="the UPF IP we want from the LB"
• upf.tun="tun subnet number - 45, 46, ..."
• upf.dnn="dnn"

Examples

Example 1 UPF

Deploying using Helm

helm install -n open5gs-hack -f values.yaml 5gcore ./ --set amf.lbIP="10.10.10.221",upf.upf1IP="10.10.10.222",dnn.upf1="dnn1"
helm install -n open5gs-hack -f values.yaml upf1 ./ --set upf.config="1",upf.lbIP="10.10.10.222",upf.tun="45",upf.dnn="internet"

Deploying using OSM (--config)

		"member-vnf-index": "1",
		"additionalParamsForKdu": [{

Example 2 UPFs (one at the central DC and one at the edge)

Deploying using Helm

# On main cluster
helm install -n open5gs-hack -f values.yaml 5gcore ./ --set amf.lbIP="10.10.10.221",upf.upfs="2",upf.upf1IP="10.10.10.222",upf.upf2IP="172.16.100.161",dnn.upf1="internet",dnn.upf2="work"
helm install -n open5gs-hack -f values.yaml upf1 ./ --set upf.config="1",upf.lbIP="10.10.10.222",upf.tun="45",upf.dnn="internet"

# On edge cluster
helm install -n open5gs-hack -f values.yaml upf2 ./ --set upf.config="2",upf.lbIP="172.16.100.161",upf.tun="46",upf.dnn="work"

UPF 2 (on edge cluster)

{

}

If the deployment goes into a CrashLoopBackoff run:

helm -n open5gs-hack ls

Get the chart name and run:

helm -n open5gs-hack uninstall chart-name
