collection failed - docker container

[devinodaniel]

Hello, I'm unable to connect to vsphere using docker. Getting a generic "collection failed" in UI.

Any ideas? Thanks

Update: using vCenter 6.7 - possible bug?
Update 2: Mistakenly had the error as "Connection failed" when it is actually "Collection failed"

Docker command

docker run -it --rm --dns=10.10.10.10 -p 9272:9272 \ 
-e VSPHERE_USER="[email protected]"  \
-e VSPHERE_PASSWORD="XXXXX" \
-e VSPHERE_HOST="libsvrvctr01.internal.customdomain.com" \
-e VSPHERE_IGNORE_SSL=True -e VSPHERE_SPECS_SIZE=2000 \ 
--name vmware_exporter pryorda/vmware_exporter

I have found that setting VSPHERE_COLLECT_VMS=False when starting the container allows me to collect metrics successfully. So something about collecting the VMs is throwing this error...

[devinodaniel]

Okay the issue appears to be when including -e VSPHERE_SPECS_SIZE=2000 as I'm starting the docker container (as it is in the example). If I remove this and let it use the default of 5000, then my container starts and collects all metrics without error.

I believe this is because VSPHERE_SPECS_SIZE might be being parsed as a string instead of an integer... thus causing the above stated error:

<class 'TypeError'>: 'str' object cannot be interpreted as an integer
