operator-sdk new app-operator failed

[ligc]

Bug Report

What did you do?
Failed to new an operator with operator-sdk CLI. The same(similiar) error with both v0.7.0 and master branch. I was able to run the "operator-sdk new" command successfully a while ago on the same node, but it does not work any more.

What did you see instead? Under which circumstances?

• Are you writing your operator in ansible, helm, or go?

I am writing the operator in go

@ligc I tried the current master branch and could not reproduce the problem. What is the version of dep you are using?

[ligc]

@lilic Thanks for looking into this, here is the dep version I am using.

[root@openshift-single-node ~]# dep version
dep:
 version     : v0.5.1
 build date  : 2019-03-11
 git hash    : faa6189
 go version  : go1.12
 go compiler : gc
 platform    : linux/amd64
 features    : ImportDuringSolve=false
[root@openshift-single-node ~]#

it is kind of strange, I was able to create operators a while ago on this same node, but it does not work any more, and I did not remember any change that may affect operator-sdk. Maybe some dep packages on internet was changed?

[lilic]

@ligc It's odd as for me it works fine locally. It seems the problem seems to be here:

unable to update checked out version: fatal: reference is not a tree: 6aac3b6efddd6824ea8578b5187eb360c42b1e63
(26)    : command failed: [git checkout 6aac3b6efddd6824ea8578b5187eb360c42b1e63]: exit status 128

This commit exists in operator-sdk, so it must be a dep cache issue. Can you try to do rm -rf $GOPATH/pkg/dep/sources/https---github.1485827954.workers.dev-operator--framework-operator--sdk/ and retry dep ensure -v in the operator root directory? This seems to have solved it for this dep issue golang/dep#484 (comment)

[ligc]

I ran the following commands, but it does not seem help, the operator-sdk new app-operator still fails.

rm -rf $GOPATH/pkg/dep/sources/https---github.1485827954.workers.dev-operator--framework-operator--sdk/
cd $GOPATH/src/github.com/operator-framework/operator-sdk/
dep ensure -v 

Inspired by your statement "it must be a dep cache issue", I completely removed the $GOPATH and re-initialized everything, then I could successfully run operator-sdk new app-operator .

I am fine with closing this issue, as I could use rm -rf $GOPATH/* as the workaround, not sure if we want to look further into this issue and try to figure out the root cause. I am currently unable to reproduce this issue any more...

Thanks

[lilic]

@ligc I think if you run into this issue next time, updating local master branch, e.g. pulling from master, in $GOPATH/src/github.com/operator-framework/operator-sdk/ should also do the trick as it seems dep was not looking in the cache.

Closing as this is solved.
