Docker - Centos - daemon: command not found

[beshoo]

Dear all, Am not sure if this is the correct place to ask for this. am inside a docker under centos 7

Am installing a tool called (https://goautodial.org/)

and one of the requirements is : ngcp-rtpengine ngcp-rtpengine-kernel ngcp-rtpengine-dkms and I installed them via YUM

  Installing : ngcp-rtpengine-dkms-6.4.0.0-1.el7.noarch                                                                                               54/145

Creating symlink /var/lib/dkms/ngcp-rtpengine/6.4.0.0-1.el7/source ->
                 /usr/src/ngcp-rtpengine-6.4.0.0-1.el7

DKMS: add completed.

I have starting problem:

I tried to Recompile the kernel module:

cd /usr/src/ngcp-rtpengine-6.4.0.0-1.el7/
make
make install

Please Advice

It seems you have issues with kmod-lve on that docker instance, isn't it?

make -C /lib/modules/3.10.0-962.3.2.lve1.5.66.el7.x86_64/build M=/usr/src/ngcp-rtpengine-6.4.0.0-1.el7 O=/lib/modules/3.10.0-962.3.2.lve1.5.66.el7.x86_64/build modules
make: *** /lib/modules/3.10.0-962.3.2.lve1.5.66.el7.x86_64/build: No such file or directory.  Stop.
make: *** [modules] Error 2

Make sure you have the necessary kernel headers installed.

That's the problem, and am not sure what should I do...

Is it something to install in docker container, or on the main host?

And what is this kernel header, please guide me?

Regard

Sorry, we don't support docker related issues here. I doubt it's related to the rtpengine software itself. So unless we see any sign it has to do with the rtpengine itself, I cannot help here much.

I suggest you to get in touch with the team administrating your docker machines, in order to take care of upgrading/fixing that mentioned kernel issue.

Hello @zenichev,

Thank you so much for your kind reply. I'm not sure if ngcp-rtpengine-dkms is supported by CentOS7 at first place, and I have a reason for saying that.

I checked https://answers.launchpad.net/ubuntu/bionic/i386/linux-tools-4.15.0-15-lowlatency/4.15.0-15.16, It appears that the ngcp-rtpengine-dkms is supported for Ubuntu OS, but not for CentOS, Am not sure.

but based on the yum installation error, and received the following message:

Error! echo Your kernel headers for kernel 4.15.0-15-lowlatency cannot be found at /lib/modules/4.15.0-15-lowlatency/build or /lib/modules/4.15.0-15-lowlatency/source.

However, my kernel host has no problem and is up-to-date with the latest version which is:

uname -r
3.10.0-962.3.2.lve1.5.82.el7.x86_64

Based on the information above, I would like to know why I keep getting this error when installing ngcp-rtpengine-dkms.

Thank you.
