Re: Jenkins 2.60.1 With Java 7 Slave Node

2017-06-24 Thread Jacob Larsen 
Sounds like you need something that isolates the "Jenkins Slave" 
functionality from your build environment. I see these solutions:


A new machine with the Jenkins Slave that does SSH to your CentOS 5 
build environment in the build step.


Put your CentOS 5 build environment in a Docker container and use one of 
these plugins:


* Docker Slaves: This plugin is marked as experimental and has not seen 
any updates this year. It works with some kinks. E.g. There is no limit 
on how many nodes it can start at once when using pipeline. This 
dynamically provisions a full slave for each build.


* Cloudbees Docker Custom Build Environment plugin. This plugin has not 
seen any updates for a couple of years, but a new maintainer is getting 
started now. This plugin attaches on an existing slave and uses the 
Jenkins Slave mechanisms for scheduling. It lacks pipeline support and 
does not work if the slave itself is running as a Docker container.

Re: Jenkins 2.60.1 With Java 7 Slave Node

2017-06-24 Thread Mark Waite 
As far as I read from Oracle JDK 8 and JRE 8 Certified System
ConfigurationsContents
,
RHEL 5.5 and later are supported by Oracle JDK 1.8.0, though there is no
JavaFX support on that platform.  Since Oracle is also a Linux vendor, it
is in their best interest to support Oracle JDK 1.8.0 on the Linux
operating systems which they support (including Oracle Linux 5, a
derivative of Red Hat Enterprise Linux 5).

The Oracle JDK installation instructions

make no particular exceptions for RHEL 5 (or for Oracle Linux 5).  It
should "just work".

Oracle offers "extended support" for Oracle Linux 5 until 26 Jun 2020.
They either have ended regular support for Oracle Linux 5 or will do so
very soon.

I suspect the same is true of Red Hat Enterprise Linux.  The Red Hat Linux
wikipedia article
 shows that
RHEL 5 is in extended support as of June 2017.

What was it that made you think that "a secure Java 8 JRE is unavailable on
CentOS 5"?

In short no
Jenkins master and slaves have to be launched with Java 8.
Java 7 and older can still be used for builds
