docker image for ppc64le

jjsk1

I'm interested in an LPAR2RRD docker image for PowerPC 64 little endian. Do you have any plans for this?

Pavel

Hi,

Docker should support it.

Our tool is in scripting languages only (perl/shell/jquery) then does not matter what enddian uses hosting operating system.

I do not know details how to use Docker on PowerPC but we support all Docker HW hosting platforms.

when i tried to run xorux docker image on ppc64le i got an error about executable format and the docker container failed to start.

i wonder if the underlying debian distribution in the image includes only i386 variants

Pavel

Hi,

it must be about your docker configuration, all we provide is executable everywhere, we do no provide any binaries.

What is exact error?

error does not say too much, is not there any possibility to run that cmd in more verbose mode to see what command failing?

I think this errror is because the linux layer included in the xerus docker image has amd64 architecture so it cannot run on ppc64le.  I was wondering if you can rebuild the image and include ppc64le as well? 


# docker image inspect <imageid> | grep Architecture 
   "Architecture": "amd54"

},
        "Architecture": "amd64",
        "Os": "linux",
        "Size": 460425468,
        "VirtualSize": 460425468,

            "Name": "overlay2",
            "Data": {

Hello,
our container is based on Debian Jessie, ppc64le is supported (https://hub.docker.com/r/ppc64le/debian).
We have to create manifest file for other platforms, unfortunately we have no access to Little Endian PowerPC host, so we cannot test it.

@Jirka

I'd be happy to test the image if you add ppc64le and report back.

update:  I found this https://github.com/goricz/XoruX

I will try to modify FROM image to ppc4le/debian and rebuild. 

I think it's not finding snmp-downloader  but the rest of the dependencies seem to be ok

jjsk1

the ppc64le build did work and successfully ran, per above

there were errors about respawning sshd and cron during startup, but i was able to ssh to the image and also got "Welcome to LPAR2RRD appliance" http screen

let me know if I can help with any other testing.

As far as finding a machine to run. Since lpar2rrd supports IBM power hardware, there is hopefully a PPC linux  lpar somewhere at Xorus??  Or may be  QEMU can be used (via processor emulation)

It would be really nice if the officially supported multiplatform docker image was available
