吊舱活动/准备状态错误

我的吊舱的活动/准备状态错误。我已经将其与其他豆荚进行了比较。

破碎的豆荚看起来像这样：

Liveness:   http-get http://:http/login delay=90s timeout=5s period=10s #success=1 #failure=12
Readiness:  http-get http://:http/login delay=60s timeout=1s period=10s #success=1 #failure=3

工作舱如下：

Liveness:    tcp-socket :8200 delay=0s timeout=1s period=10s #success=1 #failure=3
Readiness:   tcp-socket :8200 delay=0s timeout=1s period=10s #success=1 #failure=3

这是我的豆荚豆

我遇到的问题是我的詹金斯（Jenkins）吊舱无法获取插件，因此吊舱无法启动。

我在豆荚的日志中看到了这个

更新：

我试图在其他工作正常的吊舱上设置就绪/活跃度。

        readinessProbe:
          failureThreshold: 3
          periodSeconds: 10
          successThreshold: 1
          tcpSocket:
            port: 8200
          timeoutSeconds: 1

和

        livenessProbe:
          failureThreshold: 3
          periodSeconds: 10
          successThreshold: 1
          tcpSocket:
            port: 8200
          timeoutSeconds: 1

日志仍然看起来一样。

我还尝试了编辑部署，因此根本没有设置就绪/活跃性，但日志中的输出仍然相同。

如果我的理解正确-这也不是from PyQt5 import QtCore, QtGui, QtWidgets, QtChart from PyQt5.QtCore import * from PyQt5.QtChart import * data = ((0, 7380, 7520, 7380, 7510, 7324), (1, 7520, 7580, 7410, 7440, 7372), (2, 7440, 7650, 7310, 7520, 7434), (3, 7450, 7640, 7450, 7550, 7480), (4, 7510, 7590, 7460, 7490, 7502), (5, 7500, 7590, 7480, 7560, 7512), (6, 7560, 7830, 7540, 7800, 7584)) mas = [7380, 7520, 7440, 7450, 7510, 7500, 7560] x = len(mas) class MainWindow(QtWidgets.QMainWindow): def __init__(self, parent=None): super().__init__(parent) central_widget = QtWidgets.QWidget() self.setCentralWidget(central_widget) self.open_btn = QtWidgets.QPushButton("Open") self.open_btn.clicked.connect(self.add_chartview) self.close_btn = QtWidgets.QPushButton("Close") self.close_btn.clicked.connect(self.remove_chartview) hbox = QtWidgets.QHBoxLayout() hbox.addWidget(self.open_btn) hbox.addWidget(self.close_btn) series = QCandlestickSeries() tm = [] for num, o, h, l, c, m in data: series.append(QCandlestickSet(o, h, l, c)) tm.append(str(num)) self.chart = QChart() self.chart.addSeries(series) self.chart.createDefaultAxes() self.chart.legend().hide() self.chart_view = QChartView(self.chart) self.chart.axisX(series).setCategories(tm) self.splitter = QtWidgets.QSplitter(QtCore.Qt.Vertical) self.splitter.addWidget(self.chart_view) self.lay = QtWidgets.QVBoxLayout(central_widget) self.lay.insertLayout(0, hbox) self.lay.addWidget(self.splitter, stretch=1) self.resize(640, 480) def add_chartview(self): chart_view = self.splitter.widget(0) chart = chart_view.chart() self.scatter = QtChart.QScatterSeries() self.scatter.append(float(3), mas[3]) self.scatter.append(float(5), mas[5]) chart.addSeries(self.scatter) chart_view.setChart(chart) self.splitter.addWidget(chart_view) axisX = QValueAxis() chart.addAxis(axisX, Qt.AlignBottom) self.scatter.attachAxis(axisX) chart.axisX(self.scatter).setRange(0, 6) def remove_chartview(self): chart_view = self.splitter.widget(0) chart = chart_view.chart() r = chart.series() if len(r) > 1: delete = r[1] delete.deleteLater() if __name__ == "__main__": import sys app = QtWidgets.QApplication(sys.argv) w = MainWindow() w.show() sys.exit(app.exec_()) ，也没有readinessProbe问题。 例如，有可能在github上找到仍未解决的问题

Jenkins init container cannot resolve dns或stable/jenkins 1.9.17 plugins not found 404 #20738

对于那些在代理后面的人-必须在部署之前在helm / jenkins-values.yml中添加代理。我知道那不是你的情况。

默认情况下，Jenkins将尝试在安装时安装一系列插件，如果失败/超时，将导致安装未完成且失败。您可以尝试做的是添加一个空的安装插件列表。为此，您可以在部署之前将空的livenessProbe添加到installPlugins:中。

jenkins/values.yaml example

尝试一下，让我知道您是否至少能够启动吊舱。
