Golang如何处理CI/CD流水线失败重试

func doWithRetry() error {
    operation := func() error {
        resp, err := http.Get("https://api.example.com/health")
        if err != nil {
            return err // 可重试
        }
        defer resp.Body.Close()
        if resp.StatusCode != http.StatusOK {
            return fmt.Errorf("status not ok")
        }
        return nil // 成功，不再重试
    }
    return backoff.Retry(operation, backoff.WithMaxRetries(backoff.NewExponentialBackOff(), 3))
}

retry() {
  local n=1
  local max=3
  while ! "$@"; do
    if (( n >= max )); then
      echo "Command failed after $n attempts."
      return 1
    fi
    echo "Attempt $n failed. Retrying in 5 seconds..."
    sleep 5
    ((n++))
  done
}

retry go test -v ./...

TEST_RETRY_COUNT ?= 3

test-retry:
	@for i in $$(seq $(TEST_RETRY_COUNT)); do \
		echo "Running tests (attempt $$i)..."; \
		if go test -v ./...; then \
			exit 0; \
		fi; \
		sleep 5; \
	done; \
	echo "Tests failed after $(TEST_RETRY_COUNT) attempts"; \
	exit 1
