Scripts

verify-weave.sh - Goes through all weave pods in the cluster, computes a checksum on the 'status ipam' list and tells you if there are any weave pods that disagree on their peer list. It was used this to identify the different groups of pods in the cluster and decide which we wanted to preserve and which ones we wanted to reset/restart. Another quick script bump-weave.sh - Used to remove the db file and restart for those weave pods we wished to reset.

Running ./test.sh gives the below output:

test1 is empty
test2 is set (empty string)
test3 is set (has string though)
test4 is not set (does not exist at all)

Expected behaviour

The underlying file system on my machine (Mac OS X) is case sensitive (i.e. "foo" and "Foo" are considered to be different files). Mounting a shared directory (e.g. docker run -i -t -v ~/git:/code imagename) should mount as case sensitive, as well.

Actual behavior

Information

• Diagnostic ID from "Diagnose & Feedback" in the menu.
• a reproducible case if this is a bug, Dockerfiles FTW
