Can I install Docker on Red Hat server 5.9 so I can take an image container from an installed software and move it to another server?
Or should it be enough to update the Kernel up to version 3 so Docker can run?

1Why are you trying to get such an old distro to work? That's not even the latest version of RHEL5 and RHEL5 as a whole will be EOL'd next March.Bratchley– Bratchley2016-05-22 01:49:28 +00:00Commented May 22, 2016 at 1:49

@Bratchley i want to stop using the RHEL 5 and move to RHEL 7. But because I can't touch the software in the old RHEL, then i should go for VM or Docker and i prefer Docker as it's lightweight. Also I can't reinstall the software as I don't have the installation media.Leb_Broth– Leb_Broth2016-05-22 01:52:24 +00:00Commented May 22, 2016 at 1:52

Docker's website states that it can be installed on any 64 bit distribution of RHEL.
However, the kernel must be 3.10 at a minimum.
Check your kernel version first with the following command: uname -r.

The Kernel i have is 2.6, do you think if I updated it, I could harm some existing software?Leb_Broth– Leb_Broth2016-05-22 00:43:59 +00:00Commented May 22, 2016 at 0:43

1Furthermore, keep a back up of your original kernel so if something goes wrong you can reinstall back to the original kernelryekayo– ryekayo2016-05-22 00:52:21 +00:00Commented May 22, 2016 at 0:52

1To be honest, I never did a kernel upgrade on that version of RHEL but why don't you look up the steps of upgrading your kernel on RHEL 5.xryekayo– ryekayo2016-05-22 00:56:08 +00:00Commented May 22, 2016 at 0:56

1If it means anything, what I usually do when using Docker is create a VM and dedicate the VM to Docker...ryekayo– ryekayo2016-05-22 00:57:11 +00:00Commented May 22, 2016 at 0:57

1No. I just prefer to dedicate a server/VM to creating Docker scripts and running containers.ryekayo– ryekayo2016-05-22 01:00:01 +00:00Commented May 22, 2016 at 1:00
