how to find how a Jenkins instance is installed?

[g***@gmail.com]

Hello, how do I find out how a Jenkins instance has been installed?

[Victor Martinez]

There are a bunch of different options to install Jenkins based on the OS:
- https://jenkins.io/doc/book/installing/

And on the top those options, there are some configuration management tool
which can help to provisioning Jenkins on any machine, such as
puppet/ansible/chef...

Off the top of my head, it looks like that's something to search in the OS
package log events and see whether there are any entries.

My 2 cents

[Martin d'Anjou]

If you mean how do you test if an instance is ready (after a restart), you
can use curl.

httpCode=$(curl -s -w "%{http_code}" -X GET $JENKINS_URL)
while [[ $httpCode != "200" ]]; do
sleep 5
httpCode=$(curl -s -w "%{http_code}" -X GET $JENKINS_URL)
done
echo "Jenkins is ready."

I thought the question was trying to determine if the Jenkins installation
was done from apt, rpm, MSI, chocolatey, or using a war file. Interesting
the different assumptions we make to a question.

Can the original questioner clarify what they were asking?

Yes Mark, you are right. I'm trying to determine if Jenkins was installed
from apt/yum, rpm, MSI or war file. Is there a way to find how the
installation was done?

I'm not aware of any direct method from inside Jenkins that will report how
it was installed. There are differences in the file system layout from the
various installation techniques which could be used to guess which
installer was used.

For example:

- If /etc/default/jenkins exists, then it is likely an 'apt' based
installation (like Debian and Ubuntu)
- If /etc/sysconfig/jenkins exists, then it is likely an 'rpm' based
installation (like Red Hat Enterprise Linux and CentOS)

I don't know the details of installations on macOS, OpenSUSE, FreeBSD,
OpenBSD, AIX, s390x, or OpenIndiana.

I would be interested in knowing the details of OS rather than other way around.Same as Mark mentioned.

Thanks a lot @Mark for the info. We are using CentOS. Will there be a
difference between yum install and downloading a previous version and
installing it manually? Also, how to find if the installation is done from
LTS or Stable version? From OS.
