[Glass] GsDevKit for Docker

Hi,

I’m working on getting a kit together to easily setup and run GsDevKit stones on Kubernets and have an issue I need some help with.

To start with I’m simply making a docker image with the entire GsDevKit and a seaside stone installed to make sure it’s all working. I’ll create more usable components once I know I can get it installed :)

Starting with creating the docker image, there’s a slightly weird (but I guess not unexpected considering the environment) error calculating the memory sizes:

[Info] Setting up shared memory
  Total memory available is 7972 MB
  Max shared memory segment size is -16 MB
  Max shared memory allowed is -65536 MB
/opt/GsDevKit_home/bin/utils/installOsPrereqs: line 244: [: 18446744073692774399: integer expression expected
/opt/GsDevKit_home/bin/utils/installOsPrereqs: line 248: [: 18446744073692774399: integer expression expected
[Info] No need to increase max shared memory segment size
/opt/GsDevKit_home/bin/utils/installOsPrereqs: line 260: [: 18446744073692774399: integer expression expected
[Info] No need to increase max shared memory allowed

Regardless, since it’s not updating anything, it’s not really an issue - just thought I’d point it out.

I also noticed:

=================

              path: /opt/GsDevKit_home/bin/private/clone_gs_client_dev

Haven’t looked into this one yet.

The main thing I encountered was while running:

installServerSeaside -c https -z 8383 gsdevkit342 3.4.2

The error appears just before the tODE server install, while starting netldi:

Not sure about this one. It looks like startNetldi is being called with the right argument (just one string ‘gsdevkit342’) but maybe Pharo didn’t get it from the command line? Not sure how nil got into the arrayOfStrings that ended up at UnixProcess. Since this is all happening during the creation of a docker image, it makes it even harder to debug. Has anyone seen this error before, or know what could cause it?

I remember problems with netldi and hostnames, could that be the case here? Is there some confusion between “host” and “node” names:

Network lookup failure; could not find server 'gsdevkit342' on host '5521dafaa573' because file not found: /opt/gemstone/locks/gsdevkit342..LCK;  service gsdevkit342 not found ; NetLDI service 'gs64ldi' not found on node 'localhost6' port 50377 :

Any advice would be greatly appreciated.

Thanks.

PS. I’m running my own fork of GsDevKit, but I made sure it was up to date. Pretty much the only change for now is in installOSPreReqs to include ubuntu 18.04. I’ve checked this whole process with 16.04 and I get the same error so I’m pretty sure it’s not some weird OS related bug… still, ya never know :)
