链接器：设置失败应计时出现crashloopbackoff kubernetes pod错误

Question

Configured my yml with failure accrual circuit breaking, with below config as reference. https://github.com/linkerd/linkerd-examples/blob/master/failure-accrual/linkerd.yml

client:
    failureAccrual:
      kind: io.l5d.consecutiveFailures
      failures: 5
      backoff:
        kind: constant
        ms: 10000

After applying the changes, I see the pods in crashloopbackoff state.

kubectl  apply -f ./linkerd-fa.yml

Answer 1

Crashloopbackoff means that the process is failing to start. If you use kubectl logs pod/$POD_ID l5d , you should see an error message. I'm guessing there's a formatting issue with your configuration that is causing linkerd to error out during startup.

Answer 2

Linkerd provides failure accrual by default as part of each of your client configurations. The default failure accrual configuration is 5 consecutive failures, which is also what you've pasted in the YAML snippet with your question. So in this case you could omit the failureAccrual setting altogether from your config and the behavior will be the same.

Answer 3

我认为您应该删除Pod，它是Crashloopbackoff ，然后运行kubectl get pods 。
