Can you rebase your PR so conflicts are resolved ?

Generally it seems ok however a few issues i encountered;

1. we should not maintain duplicated crds under deploy/ and under config/crd
2. example folder should have up2date crds taken from config/crd or better yet remove them and update deploy/delete scripts to deploy the crds directly from their original directory WDYT?
3. make image fails to build in my setup, does it work in yours ?
4. i noticed a few targets added in Makefile, do they work ?

also a general question:
did you use this migration guide ?

udated

1. we should not maintain duplicated crds under deploy/ and under config/crd

not duplicated but auto-generated, as discussed it will be removed in a new commit and update the example

2. example folder should have up2date crds taken from config/crd or better yet remove them and update deploy/delete scripts to deploy the crds directly from their original directory WDYT?

it will be updated in new commit

3. make image fails to build in my setup, does it work in yours ?

The issue is related to the new test in controllers/suite_test.go, it fails in the source command because the SHELL default is /bin/sh which doesn't contain source (I used . but still fails with other errors if you check the latest ci failure)
/bin/bash doesn't exist in the docker image golang/alpine
currentlly trying to fix this issue

4. i noticed a few targets added in Makefile, do they work ?

yes

also a general question:
did you use this migration guide ?

yes

@Mmduh-483 i see nic_operator CI is failing

@AbdYsn need to adjust the new updates since this PR replace the template in deploy by example/deploy

[adrianchiris]

So i have reviewed this
a few nits and we are good to merge once CI passes:

1. rename deploy.sh under scripts to docker-push.sh or similar as its confusing with deploy-operator.sh found there as well
2. remove hack folder as it contains no meaningful info
3. README.md L231 and L233 replace "Template" with "Example"
4. example/README.md update Content section as it no longer contains the deploy/delete-operator
5. example/README.md update setup cluster section, make deploy does not work when you are in example folder (change command to make -C ./.. deploy

@adrianchiris Updated the PR except for 2, hack has the boilerplate.go.txt which contain the header you want to be added to the auto-generated go files, in our case the license, please check the rule generate in Makefile 194
