I'm trying to set up gofabric8 env locally on my MAC on top of minikube.
The installation of both is done using the homebrew packages manager.
Unfortunately, I'm stuck at the very first step.
while executing gofabric8 deploy command, I get
panic: assignment to entry in nil map

I'm facing an issue with Rancher 2.5.15 where the main Rancher pod and eks-config-operator are constantly crashing and rebooting. This started around 2 weeks ago without any change in the deployed Rancher application, which we confirmed by restoring a snapshot 5 days prior to this issue appearing, with no change.
I assume the issue is due to a registered EKS cluster having issues when returning the cluster information, as it's failing on a function called BuildUpstreamClusterState, however it doesn't indicate which cluster it may be. Deleting the clusters from Rancher is not an option, as there are several EKS clusters added, and since some of them were provisioned from Rancher itself, deleting the clusters from the Rancher UI will also delete them from AWS.
The clusters themselves are working correctly, including the cluster where Rancher is running.
Full log of the panic event:

we use github.com/gogo/protobuf, I get service crash at proto.Marshal(), this happens almost once a day,But I did not receive a memory alarm，This looks like a memory leak，has anyone encountered this situation?

an extremely weird problem happened recently. my program was running on a docker which has 8GB memory and 4GB was used when the panic happened. there were more than 4GB memory available, why could this happen? below is the panic stack output.
# ulimit -m
unlimited
# go version
1.6.2
i tried to run the code line getAllCombinationComplex repeatedly, and the memory-used grew to about 5GB but the panic did not happen again.

Analyzing the stack trace, it looks you are attempting to allocate a far-too-large slice here: db_template.XCludeList.getAllCombinationComplex()
indexdb/db_template.XCludeList.getAllCombinationComplex(0xea4382c480, 0x8, 0x9, 0xe4ec1dc460, 0x4, 0x4, 0x0, 0x0, 0x0)
/home/scmbuild/workspaces_cluster/index/src/indexdb/db_template/db.go:145 +0x371 fp=0xea27f3ca88 sp=0xea27f3c900
This calls into runtime.makeslice():
runtime.makeslice(0xa38840, 0x3ecc38680, 0x3ecc38680, 0x0, 0x0, 0x0)
/usr/local/go1.6.2/src/runtime/slice.go:32 +0x165 fp=0xea27f3c900 sp=0xea27f3c8b0
The source code for runtime.makeslice() for Go 1.6 is here: slice.go:
func makeslice(t *slicetype, len64, cap64 int64) slice {
...
}
And it is called with params:
runtime.makeslice(0xa38840, 0x3ecc38680, 0x3ecc38680, 0x0, 0x0, 0x0)
The second value is the length, which is
0x3ecc38680 = 16857138816
You attempt to create a slice with more than 16*109 elements. If the element type of the slice would require the minimum of 1 byte (excluding the zero-sized types), this would be roughly 16 GB! And this is just a lower estimation. Obviously this operation cannot succeed with 8 GB of RAM available.
Also, please update your Go, 1.6.2 is almost 3 years old, not supported anymore (doesn't even receive security patches).

can anyone help me to resolve this issue?
I'm getting Golang errors in my OSX terminal when I press enter multiple times. There's a known issue with OSX Sierra and Golang version 1.4.2. I don't have Golang version 1.4.2 but the stacktrace is referring to that so my assumption is that there is an application somewhere using the old version.
Is there a way I can enable verbose logging or find out the util/daemon that is causing the error? The stacktrace is below:

Give brew upgrade go a try as this seems to be resolved in later versions, even if you didn't install with brew originally, the install path is the same so brew should solve it for you.
(Moving my comment as an answer to mark this question as resolved).
Ended up fixing it. Manually went through my utilities and isolated direnv (github.com/direnv/direnv) as the problematic utility. I must have compiled it using old Go version.
