Mastering Service Mesh

Shifting traffic permanently

If it has been determined that 100% of the traffic should now be shifted to v2 of api after testing it successfully, the weight can be defined as 100% to subset v2. This can be done with the following code:

# Script: 16-service-splitter-100-shift.hcl...splits = [  {    weight = 0,    service_subset = "v1"  },  {    weight = 100    service_subset = "v2"  }]

1. Create service-splitter for the Consul service api using the Consul CLI using 16-service-splitter-100-shift.hcl:

$ consul config write 16-service-splitter-100-shift.hcl$ consul config list -kind service-splitterapi

2. Repeat the same curl command 10 times, like so:

$ curl -s http://localhost:30145?[1-10] | grep "Pod Name.*api"Pod Name : api-v2-5d64d5f8ff-zlcp6Pod Name : api-v2-5d64d5f8ff-zlcp6 ...
