Question

我通常发现自己出于开发目的而制作docker-compose环境。

但是，当我使用docker-compose up -d启动服务时，要做的一件令人讨厌的事情是每次所有服务崩溃时都必须运行docker-compose logs -f。

我希望能够运行一个尝试来运行docker-compose logs -f的脚本，然后一旦成功，就可以照常运行。然后，一旦服务关闭，请继续尝试运行，直到再次启动。

这有意义吗？我已经尝试过使用watch了，但是这并不符合我的要求，尝试使用sleep命令执行循环也不会产生任何有用的结果。

如果要循环运行命令，只需：

var path="http://www.example.com/fileread.php"
    $.get(path, function(data){
    content= data;
    alert(content);
    //then do whatever you need to with content...
    };

它将每秒运行import javax.swing.*; import java.awt.*; import java.awt.geom.*; import java.awt.event.*; public class Main extends JPanel { public static void main(String args[]) throws Exception { JFrame f = new JFrame("Shapes"); f.setSize(600, 600); f.setLocation(300, 300); f.setResizable(true); JPanel p = new JPanel() { int x2 = 250; int y2 = 175; //for line int x1 = 315; int y1 = 115; int ex2 = 315; int ey2 = 115; //Middle Positive Sign private Shape lineMp = null; private Shape lineMn = null; //Border Positive Sign private Shape lineBp = null; private Shape lineBn = null; //Line private Shape line = null; { //Middle positive lineMn = new Line2D.Double(235,175,265,175); lineMp = new Line2D.Double(250,160,250,190); //Border sign lineBn = new Line2D.Double(300,115,330,115); lineBp = new Line2D.Double(315,115,315,130); //Line line = new Line2D.Double(x1,y1,x2,y2); MouseAdapter mouseAdapter = new MouseAdapter() { private Point prevPoint; @Override public void mousePressed(MouseEvent e) { prevPoint = e.getPoint(); System.out.println("Prev Point=" + prevPoint.toString()); repaint(); } @Override public void mouseDragged(MouseEvent e) { int dx = 0; int dy = 0; dx = (int) (prevPoint.x - e.getPoint().getX()); dy = (int) (prevPoint.y - e.getPoint().getY()); //Middle Positive sign Line2D shapeMn = (Line2D) lineMn; Line2D shapeMp = (Line2D) lineMp; //Border sign Line2D shapeBn = (Line2D) lineBn; Line2D shapeBp = (Line2D) lineBp; //Line Line2D shapeline = (Line2D) line; //Middle Positive sign int nx1 = (int) (shapeMn.getX1() - dx); int ny1 = (int) (shapeMn.getY1() - dy); int nx2 = (int) (shapeMn.getX2() - dx); int ny2 = (int) (shapeMn.getY2() - dy); int px1 = (int) (shapeMp.getX1() - dx); int py1 = (int) (shapeMp.getY1() - dy); int px2 = (int) (shapeMp.getX2() - dx); int py2 = (int) (shapeMp.getY2() - dy); //Border sign int Bnx1 = (int) (shapeBn.getX1() - dx); int Bny1 = (int) (shapeBn.getY1() - dy); int Bnx2 = (int) (shapeBn.getX2() - dx); int Bny2 = (int) (shapeBn.getY2() - dy); int Bpx1 = (int) (shapeBp.getX1() - dx); int Bpy1 = (int) (shapeBp.getY1() - dy); int Bpx2 = (int) (shapeBp.getX2() - dx); int Bpy2 = (int) (shapeBp.getY2() - dy); //Line int x2 = (int) (shapeline.getX2() - dx); int y2 = (int) (shapeline.getY2() - dy); int ex1 = (int) (shapeline.getX1() - dx); int ey1 = (int) (shapeline.getY1() - dy); Point startPointMn = new Point(nx1, ny1); Point endPointMn = new Point(nx2, ny2); Point startPointMp = new Point(px1, py1); Point endPointMp = new Point(px2, py2); Point startPointBn = new Point(Bnx1, Bny1); Point endPointBn = new Point(Bnx2, Bny2); Point startPointBp = new Point(Bpx1, Bpy1); Point endPointBp = new Point(Bpx2, Bpy2); Point startPoint = new Point((int)shapeline.getX1(), (int)shapeline.getY1()); Point endPoint = new Point(x2, y2); Point estartPoint = new Point(ex1, ey1); Point eendPoint = new Point((int)shapeline.getX2(), (int)shapeline.getY2()); GeneralPath Mp = new GeneralPath(); Mp.append(lineMn, false); Mp.append(lineMp, false); if (Mp.getBounds().contains(prevPoint)) { shapeline.setLine(startPoint,endPoint); shapeMn.setLine(startPointMn, endPointMn); shapeMp.setLine(startPointMp, endPointMp); prevPoint = e.getPoint(); repaint(); return; } GeneralPath Bp = new GeneralPath(); Bp.append(lineBn, false); Bp.append(lineBp, false); if (Bp.getBounds().contains(prevPoint)) { shapeline.setLine(estartPoint, eendPoint); shapeBn.setLine(startPointBn, endPointBn); shapeBp.setLine(startPointBp, endPointBp); prevPoint = e.getPoint(); repaint(); return; } } @Override public void mouseReleased(MouseEvent e) { repaint(); } }; addMouseListener(mouseAdapter); addMouseMotionListener(mouseAdapter); } public void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g; g2d.setPaint(Color.BLUE); g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); if (lineMn != null){ g2d.draw(line); g2d.draw(lineBn); g2d.draw(lineBp); g2d.draw(lineMn); g2d.draw(lineMp); } }}; f.add(p); p.setLayout(null); f.setVisible(true); } }。

while sleep 1; do docker-compose logs -f; done每个时段都会清除屏幕，因此您将看不到所有消息。

服务关闭时重新尝试docker-compose日志-f？
