Rsyslog config error

[benibr]

With the current master branch the container complain about the rsyslog.conf not being parsable.

Is this a known problem?

No, it's not something I've come across before and I just tested that dev-erda runs without such issues rebuilt on latest docker-migrid. Can you elaborate on which container you build (centos7, rocky8 or rocky9), and perhaps enlighten us about your env variables - mainly if you set any GDP env variables which will cause additional rsyslog.conf changes?

Until line 20 the rsyslog.conf should only have comments and one actual config line:

[root@dev app]# head /etc/rsyslog.conf| egrep -v '^#|^$' 
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)

[benibr]

This happens with current master branch when building the image with rocky8 but it works with CentOS 7.

Steps to reproduce:

git clone https://github.com/ucphhpc/docker-migrid
cd docker-migrid
ln -sf Dockerfile.rocky8 Dockerfile
make
docker-compose up

Then you see the errors from the various containers that rsyslog.conf is not parsable.

The problem is that the sed commands in the Dockerfile aren't sufficient. I guess the default config coming from the rsyslog package has changed. The result looks like this:

#  egrep -v '^#|^$' /etc/rsyslog.conf | head -n 6
module(load="imuxsock"    # provides support for local system logging (e.g. via logger command)
       SysSock.Use="on") # Turn off message reception via local log socket;
                          # local messages are retrieved through imjournal now.
       UsePid="system" # PID nummber is retrieved as the ID of the process the journal entry originates from
global(workDirectory="/var/lib/rsyslog")
module(load="builtin:omfile" Template="RSYSLOG_TraditionalFileFormat")
...

Confirmed on rocky8 - thanks for reporting it and clarifying the scope. I'll take a look.

It should be fixed in 8e2d919634c4d7d866170346925804933745c348 , which I tested with podman on rocky8. Please verify and reopen the issue if not.
