English | 中文

The Volcaengine Kubernetes Engine supports the CLB reuse mechanism in k8s. Different SVCs can use different ports of the same CLB. Therefore, the Volcengine-CLB network plugin will record the port allocation corresponding to each CLB. For the specified network type as Volcengine-CLB, the Volcengine-CLB network plugin will automatically allocate a port and create a service object. Wait for the svc ingress field. After the public network IP is successfully created, the GameServer network is in the Ready state and the process is completed.

Volcengine-CLB configuration

plugin configuration

[volcengine]
enable = true
[volcengine.clb]
#Fill in the free port segment that clb can use to allocate external access ports to pods, The maximum port range is 200.
max_port = 700
min_port = 500

Parameter

ClbIds

• Meaning：fill in the id of the clb. You can fill in more than one. You need to create the clb in [Volcano Engine].
• Value：each clbId is divided by , . For example: clb-9zeo7prq1m25ctpfrw1m7,clb-bp1qz7h50yd3w58h2f8je,...
• Configurable：Y

PortProtocols

• Meaning：the ports and protocols exposed by the pod, support filling in multiple ports/protocols
• Value：port1/protocol1,port2/protocol2,... The protocol names must be in uppercase letters.
• Configurable：Y

AllocateLoadBalancerNodePorts

• Meaning：Whether the generated service is assigned nodeport, this can be set to false only in clb passthrough mode
• Value：false / true
• Configurable：Y

Fixed

• Meaning：whether the mapping relationship is fixed. If the mapping relationship is fixed, the mapping relationship remains unchanged even if the pod is deleted and recreated.
• Value：false / true
• Configurable：Y

AllowNotReadyContainers

• Meaning：the container names that are allowed not ready when inplace updating, when traffic will not be cut.
• Value：{containerName_0},{containerName_1},... eg：sidecar
• Configurable：It cannot be changed during the in-place updating process.

Annotations

• Meaning：the anno added to the service
• Value：key1:value1,key2:value2...
• Configurable：Y
