ubuntu - Docker.io init.d 脚本在启动容器上不起作用

Question

我有一个带有 odoo 的容器在目录“/opt/odoo/”上。

“/etc/init.d/odoo-server”上的初始化脚本

#!/bin/bash
### BEGIN INIT INFO
# Provides:          odoo
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Start openerp daemon at boot time
# Description:       Enable service provided by daemon.
# X-Interactive:     true
### END INIT INFO
## more info: http://wiki.debian.org/LSBInitScripts

PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin
DAEMON=/opt/odoo/openerp-server
NAME=odoo
DESC=odoo
CONFIG=/etc/odoo-server.conf
LOGFILE=/var/log/odoo/odoo-server.log
PIDFILE=/var/run/${NAME}.pid
USER=odoo
export LOGNAME=$USER

test -x $DAEMON || exit 0
set -e

function _start() {
    start-stop-daemon --start --quiet --pidfile $PIDFILE --chuid $USER:$USER --background --make-pidfile --exec $DAEMON -- --config $CONFIG --logfile $LOGFILE
}

function _stop() {
    start-stop-daemon --stop --quiet --pidfile $PIDFILE --oknodo --retry 3
    rm -f $PIDFILE
}

function _status() {
    start-stop-daemon --status --quiet --pidfile $PIDFILE
    return $?
}


case "$1" in
        start)
                echo -n "Starting $DESC: "
                _start
                echo "ok"
                ;;
        stop)
                echo -n "Stopping $DESC: "
                _stop
                echo "ok"
                ;;
        restart|force-reload)
                echo -n "Restarting $DESC: "
                _stop
                sleep 1
                _start
                echo "ok"
             ;;
        status)
                echo -n "Status of $DESC: "
                _status && echo "running" || echo "stopped"
                ;;
        *)
                N=/etc/init.d/$NAME
                echo "Usage: $N {start|stop|restart|force-reload|status}" >&2
                exit 1
                ;;
esac

exit 0

那我做

root@cca438c81a87:/# update-rc.d odoo-server defaults
 Adding system startup for /etc/init.d/odoo-server ...
   /etc/rc0.d/K20odoo-server -> ../init.d/odoo-server
   /etc/rc1.d/K20odoo-server -> ../init.d/odoo-server
   /etc/rc6.d/K20odoo-server -> ../init.d/odoo-server
   /etc/rc2.d/S20odoo-server -> ../init.d/odoo-server
   /etc/rc3.d/S20odoo-server -> ../init.d/odoo-server
   /etc/rc4.d/S20odoo-server -> ../init.d/odoo-server
   /etc/rc5.d/S20odoo-server -> ../init.d/odoo-server

当我使用 docker start 启动 docker 时，odoo-server 没有启动，当我在 docker/etc/init.d/odoo-server start 内部运行时，它可以正常工作...

发生了什么？

Docker 容器通常没有正常运行的初始化系统。如果您只是运行一个服务——只需启动它。

如果您需要更复杂的东西，请查看 supervisord或 runit .

容器不是虚拟机。
