2. Create your source log configuration file: /etc/rsyslog.d/hapac2.conf

$template NetworkLog, "/var/log/hapac2.log"
:fromhost-ip, isequal, "192.168.3.1" -?NetworkLog
& ~

3. Enable rsyslog to listen to remote request, uncomment below entries in file /etc/rsyslog.conf

module(load="imudp")
input(type="imudp" port="514")

module(load="imtcp")
input(type="imtcp" port="514")

4. Touch /var/log/hapac2.log

5. Restart rsyslog daemon:

export $PYPATH=`which python3`
wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz
tar -Jxf Python-3.6.5.tar.xz
cd Python-3.6.5/
./configure && make && make altinstall
rm $PYPATH
ln -s `which python3.6` $PYPATH
python3 -m pip install pyyaml
python3 env/common_config/add_imagepullsecret.py

Solution 2: use virtualenv
