Mastering Service Mesh

Round-robin traffic

Traffic can be split in a round-robin fashion by specifying a 50-50 weight for both services, as follows:

# Script: 15-service-splitter-round-robin.hcl...splits = [  {    weight = 50,    service_subset = "v1"  },  {    weight = 50    service_subset = "v2"  }]

1. Create service-splitter for api by assigning a 50-50 weight to each subset using 15-service-splitter-round-robin.hcl:

$ consul config write 15-service-splitter-round-robin.hcl$ consul config list -kind service-splitterapi

2. Repeat the same curl command 10 times. You will notice that the traffic is split equally between the api-v1 and api-v2 pods:

$ curl -s http://localhost:30145?[1-10] | grep "Pod Name.*api"Pod Name : api-v1-7fcf5d98d4-tgqrkPod Name : api-v1-7fcf5d98d4-tgqrkPod ...
