我希望你能帮助我.这需要一些解释......
TLDR问题:为什么线程进程会从解释器中按预期运行(分离的python线程),myprocess.start()但是当从终端运行时阻塞子线程python myprocess.py?
背景:我threading.Thread为我的类子类化,它也调用了另外两个Thread类型的子类.看起来像:
class Node(threading.Thread):
def __init__(self, gps_device):
threading.Thread.__init__(self)
self.daemon = False
logging.info("Setting up GPS service")
self.gps_svc = gps.CoordinateService(gps_device)
self.gps_svc.daemon = True
logging.info("Setting up BLE scanning service")
# TODO: This is blocking when run in terminal (aka how we do on Raspberry Pi)
self.scan_svc = scan.BleMonitor()
self.scan_svc.daemon = True
logging.info("Node initialized - ready for start")
def run(self):
self.gps_svc.start()
self.scan_svc.start() # blocks here in terminal

我正在尝试使用 Docker 和Docker Compose创建一个容器化应用程序。我有一个 PubNub 帐户,它允许我为不同的环境(开发、测试、生产)使用不同的 API 密钥。为了帮助我为此构建图像,我尝试使用带有env_file 的构建参数集。
它不起作用。

太长了;我找不到在 docker 容器中启动 NiFi 并仍然访问 UI 的正确方法。这是我尝试过的(8小时):

我去localhost:8080/nifi- 超时。同样的127.0.0.1。
docker inspect nifi- IP网关是172.20.0.1具有实际IP的172.0.0.2。Invalid Host Header和超时。
开始随机尝试一些东西:
