Smokeping doesn't start

Expected Behavior

A functional Smokeping

When the dig command is runned directly in the container

The date of the container is still

root@50708294fadc:/# date
Thu Jan  1 01:00:00 CET 1970

And when I try to display a page with ping results, in apache2 logs, the following errors are throwned

Previously, the Target file worked fine of standard Smokeping installation (without Docker)

Steps to Reproduce

  1. Fresh install of the OS
    2.Fresh install of Docker
  2. Fresh install of the Smokeping Container

Environment

OS: Raspbian GNU/Linux 10
CPU architecture: arm32 (RPi 3B)
How docker service was installed: from the official docker repo

Command used to create docker container (run/create/compose/screenshot)

docker run -d
--name=smokeping
-e PUID=1000
-e PGID=1000
-e TZ=Europe/Paris
-p 80:80
-v /smokeping/config:/config
-v /smokeping/data:/data
--restart unless-stopped

Thanks for opening your first issue here! Be sure to follow the bug or feature issue templates!

thespad commented

Please read your container log output again, it tells you how to resolve this issue.

PPCM commented

Your answer is to quick

You are talking about

Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message

This doesn't block Apache execution

The problem is more with

ERROR: output of '/usr/bin/dig localhost' does not match (?^i:query time:\s+([0-9.]+)\smsec.*)
 at (eval 71) line 1.

and

root@50708294fadc:/# /usr/bin/dig localhost
time.c:126: Operation not permitted
timer.c:634: fatal error: RUNTIME_CHECK(isc_time_now((&now)) == 0) failed
Aborted (core dumped)

Otherwise, how do you set the name of your container?

thespad commented

Yes, and if you read the container logs you posted it will tell you how to fix it.

PPCM commented

OK, I had an entry for Servername in httpd.conf.
It corrects the error line for

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message
ERROR: output of '/usr/bin/dig localhost' does not match (?^i:query time:\s+([0-9.]+)\smsec.*)

ERROR: output of '/usr/bin/dig localhost' does not match (?^i:query time:\s+([0-9.]+)\smsec.*)
 at (eval 71) line 1.

No more errors in docker logs

But nothing is generated. I will open an other ticket because the ping fails (clock_gettime errors)

j0nnymoe commented

@PPCM could you post an updated copy of your docker log smokeping please? It sounds like the error is still there.

It displays no error

But the problem is else where
I can ping a server from the host, but not from the container

From the host

pi@smokeping:~ $ ping 172.20.0.1
PING 172.20.0.1 (172.20.0.1) 56(84) bytes of data.

Thanks for your help

Your docker logs are still showing a clear error and it mentions a link to fix.

It is written to large
Thanks, I take a look how to fix it

Thanks a lot
After installing libseccomp2_2.5.1-1_armhf, all problems are gone
