go-zero出现retrying of unary invoker failed或者Auto sync endpoints failed

看看是不是docker-compose.yaml 的环境变量ETCD_ADVERTISE_CLIENT_URLS=http://etcd:2399这个配置错了，这个端口要跟对外暴露端口一致。etcd指服务ip，可以配置一个主机名etcd

{
    "level":"warn",
    "ts":"2022-01-29T10:51:48.408+0800",
    "logger":"etcd-client",
    "caller":"v3@v3.5.1/retry_interceptor.go:62",
    "msg":"retrying of unary invoker failed",
    "target":"etcd-endpoints://0xc0003c0000/etcd:2399",
    "attempt":0,
    "error":"rpc error: code = DeadlineExceeded desc = latest balancer error: last connection error: connection closed before server preface received"
}

{
    "level":"info",
    "ts":"2022-01-29T10:51:48.409+0800",
    "logger":"etcd-client",
    "caller":"v3@v3.5.1/client.go:207",
    "msg":"Auto sync endpoints failed.",
    "error":"context deadline exceeded"
}
