Question

我正在关注Restcomm Docker Quick Start Guide。我正在尝试在我安装了docker的“大型”VM（8GB内存和4vCPU）上启动restcomm connect。我是一个公司的http代理，因此开箱即用“docker-compose up”是不够的。我创建了自己的restcomm / restcomm docker镜像：我克隆了Restcomm-Docker git项目并进行了一些更改：

我在Dockerfile和scripts / {restcomm_autoconf.sh，restcomm_sslconf.sh}中添加了http_proxy和https_proxy ENV指令，以便所有wgets都能正常工作。

我在RCBCONF_STATIC_ADDRESS的Restcomm-Connect / docker-compose.yml中配置了VM IP地址。

当我构建“自定义”docker镜像时，我在apt-get安装步骤中有一些错误消息：

docker build -t restcomm/restcomm:latest -f Dockerfile .
...
Setting up x11-common (1:7.7+13ubuntu3) ...

insserv: can not remove(../rc0.d/K01hwclock.sh): No such file or directory
insserv: can not remove(../rc0.d/K01sendsigs): No such file or directory
...

所以我检查了您依赖的原始docker图像（phusion / baseimage）并找到了那些奇怪的文件：

run -it phusion/baseimage bash

对不起，这可能是一个非常常见的问题，但在谷歌上没有发现任何明显的问题。

然后，当我运行docker-compose时，我有以下错误消息：

restcomm_1  | *** Running /etc/my_init.d/restcomm6.sh...
restcomm_1  | mv: cannot remove '/etc/service/cron/run': No such file or directory
restcomm_1  | mv: cannot remove '/etc/service/sshd/down': No such file or directory

restcomm_1  | mv: cannot remove '/etc/service/syslog-forwarder/run': No such file or directory
restcomm_1  | mv: cannot remove '/etc/service/syslog-ng/run': No such file or directory

然后循环中出现以下错误消息：

restcomm_1  | *** Running /etc/rc.local...
restcomm_1  | *** Booting runit daemon...
restcomm_1  | *** Runit started as PID 281
restcomm_1  | runsv syslog-ng: fatal: unable to start ./run: file does not exist

restcomm_1  | runsv cron: fatal: unable to start ./run: file does not exist
restcomm_1  | runsv sshd: fatal: unable to start ./run: file does not exist

我认为这与我在构建docker镜像时遇到的问题有关，但我并不是百分之百确定。

我在Docker镜像中将Restcomm-Docker / scripts / restcomm-runlevels.sh中的以下行添加为/etc/my_init.d/restcomm6.sh：

cp -pR /etc/service/* /etc/runit/runsvdir/current/

这可能是以前错误消息的来源。它应该只添加正确的脚本吗？

编辑1： 我在Restcomm-Docker / scripts / restcomm-runlevels.sh中注释掉了以下块：

#cd /etc/runit/runsvdir
#ln -s default /etc/runit/runsvdir/current
#cp -pR /etc/service/* /etc/runit/runsvdir/current/
#mv -f /etc/service /service.old && ln -s /etc/runit/runsvdir/current /etc/service

现在restcomm服务启动但我觉得有些东西多次启动（由于我的更改，可能是不合适的runit监控？）：我可以在不同的线程中看到以下行和后续日志块两次：

Initializing RVD. Project version: 1.13

然后以绑定异常结束：

Answer 1

我发现了问题的来源。它与docker / var / lib / docker底层文件系统有关。我有一个xfs文件系统，它没有使用d_type支持格式化。我将一个新卷附加到我的（openstack）VM，使用d_type参数对其进行格式化并且它有效！实际上，没有这个选项，它会混淆phusion / baseimage，然后间接地依赖于这个图像的restcomm图像。

以下是详细信息：

# docker info
...
Storage Driver: overlay
 Backing Filesystem: xfs
 Supports d_type: false
...
WARNING: overlay: the backing xfs filesystem is formatted without d_type support, which leads to incorrect behavior.
         Reformat the filesystem with ftype=1 to enable d_type support.
         Running without d_type support will not be supported in future releases.

这就是我发现问题的方法。用xfs_info确认：ftype = 0，应为1

[root@yohann telestax]# xfs_info /
meta-data=/dev/vda1              isize=256    agcount=10, agsize=524224 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=0        finobt=0 spinodes=0
data     =                       bsize=4096   blocks=5240950, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=0
log      =internal               bsize=4096   blocks=2560, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0
[root@yohann telestax]#

在openstack上创建了一个新卷

将此卷附加到正在运行的实例

（创建的设备是/ dev / vdb）

使用“fdisk / dev / vdb”创建分区

命令：n，p，1和默认

然后“w”写分区表

使用正确的参数在此分区上创建xfs文件系统：

[root@yohann centos]# mkfs.xfs -n ftype=1 /dev/vdb1
meta-data=/dev/vdb1              isize=512    agcount=4, agsize=655296 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=1        finobt=0, sparse=0
data     =                       bsize=4096   blocks=2621184, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=1
log      =internal log           bsize=4096   blocks=2560, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0
[root@yohann centos]#

停止使用docker

，挂载此文件系统：

rm -fr /var/lib/docker
mkdir /var/lib/docker
mount /dev/vdb1 /var/lib/docker/

然后，docker info提供了正确的详细信息：

docker info
...
Storage Driver: overlay
 Backing Filesystem: xfs
 Supports d_type: true
...
(no more warning)

成功尝试使用baseimage：

[root@yohann centos]# docker run -it phusion/baseimage bash

（没有更多的符号链接问题）

然后，我重建了restcomm docker图像并使用“docker-compose up”再次运行它。

我使用https://myip:8443进行了测试 administrator@company.com，密码：RestComm

它有效！（它与http上的污染图像无关。）

restcomm phusion baseimage runsv无法启动./run：文件不存在
