internal/plugins: Add kustomize as a prerequisite of Makefile's bundle target #4090

miguelsorianod · 2020-10-22T18:48:15Z

Description of the change:

bundle target in the autogenerated Makefile for new golang based operator projects generated
by the operator-sdk make use of the kustomize CLI tool. This commit adds the kustomize Makefile
target as a prerequisite of the bundle target.

Motivation for the change:

When running make bundle an error is returned if kustomize is not previously installed in $PATH.

Execution example:

msoriano@localhost:~/go/src/github.com/3scale/apicast-operator (update-operator-sdk-to-110)$ make bundle which: no kustomize in (/home/msoriano/.rbenv/shims:/home/msoriano/.rbenv/bin:/home/msoriano/.nvm/versions/node/v10.21.0/bin:/usr/share/Modules/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/home/msoriano/.local/bin:/home/msoriano/bin:/usr/local/go/bin:/home/msoriano/go/bin) /home/msoriano/go/bin/controller-gen "crd:trivialVersions=true" rbac:roleName=manager-role webhook paths="./..." output:crd:artifacts:config=config/crd/bases operator-sdk-v1.1.0 generate kustomize manifests -q cd config/manager && /home/msoriano/go/bin/kustomize edit set image controller=controller:latest /bin/bash: /home/msoriano/go/bin/kustomize: No such file or directory make: *** [Makefile:126: bundle] Error 127

Hi,

I've also added a new separate commit containing a changelog fragment. If you see it ok and you want me to squash it just tell me.

Let me know if there's something else I might be missing.

Thank you.

Suggested change

In the `Makefile` file add the `kustomize` target as

a prerequisite of the `bundle` target.

In the `Makefile` file, replace `bundle: manifests` with `bundle: manifests kustomize` to call

the kustomize target when the `bundle` target is used.

Suggested change

Add `kustomize` as a prerequiste target of the `bundle`

target in the autogenerated Makefile on Golang based

operator projects.

For Golang based operators, fix an error faced when the [kustomize](https://kubernetes-sigs.github.io/kustomize/) is not installed locally and the Makefile target `bundle` is used by adding the kustomize target on it.

Changed. Instead of when the kustomize is not installed locally... I've written when the kustomize binary is not installed locally...

camilamacedo86

It shows fine for me. Just some nits.
However, @estroz wdyt ?

Do you want me to squash the changelog fragment commit into the other commit?

estroz · 2020-10-22T20:09:14Z

You can also remove the explicit make kustomize from our samples generators: here, here, and here. All make targets that require kustomize should call it as a dependency, so a samples generator should error out if one does not.

estroz

One nit and I'd like to see the samples generator updated so we know this change works as intended.

Added the `kustomize` make dependency to the `bundle` target scaffolded

for Golang projects to install `kustomize` before running.

👍 changed. However, take into account that the previous text was suggested by @camilamacedo86, so, whatever you prefer.

I thought that we had defined the standard of For Golang based operators, For Helm based operators and etc ...
However, it is fine 👍 I am ok with the new wording suggested by @estroz as well.

Hi,

You can also remove the explicit make kustomize from our samples generators: here, here, and here. All make targets that require kustomize should call it as a dependency, so a samples generator should error out if one does not.

If I'm understanding correctly, we can now remove the explicit call to the kustomize Makefile target in the sample generators code due to we've added the kustomize target as a prerequisite of the bundle target, and this target is indirectly called through the method RunOlmIntegration (defined in hack/generate/samples/internal/pkg/utils.go) that is called for all of the operator types (Go, Ansible, Helm).

I've applied the changes to remove those explicit calls.

In the case of Ansible and Helm the kustomize target was already a prerequisite of the bundle target Makefile so I understand those explicit calls in those generators could already have been removed from the samples generator code without the changes in this PR

I've done the following to verify the newer changes:

Remove the kustomize binary from my $PATH
Execute make generate
Verify that no changes have been applied in the testdata directory.

Also, to verify that the order in which the generators are run doesn't affect the execution I've executed the generation of each sample generator individually by temporarily commenting code for the others in hack/generate/samples/generate_all.go.

Additionally, interestingly enough, I've observed that Ansible and Helm generators install the kustomize binary in the bin directory relative to the corresponding sample project. However, with Go that's not the case. In Go's case it is installed in $GOBIN/kustomize. Is that intentional for some reason?

As you can see, the kustomize target in Go's generated Makefile (testdata/go/memcached-operator/Makefile) is:

kustomize: ifeq (, $(shell which kustomize)) @{ \ set -e ;\ KUSTOMIZE_GEN_TMP_DIR=$$(mktemp -d) ;\ cd $$KUSTOMIZE_GEN_TMP_DIR ;\ go mod init tmp ;\ go get sigs.k8s.io/kustomize/kustomize/v3@v3.5.4 ;\ rm -rf $$KUSTOMIZE_GEN_TMP_DIR ;\ } KUSTOMIZE=$(GOBIN)/kustomize else KUSTOMIZE=$(shell which kustomize) endif

Whereas for Ansible (testdata/ansible/memcached-operator/Makefile) and Helm (testdata/helm/memcached-operator/Makefile) is:

kustomize: ifeq (, $(shell which kustomize 2>/dev/null)) @{ \ set -e ;\ mkdir -p bin ;\ curl -sSLo - https://github.com/kubernetes-sigs/kustomize/releases/download/kustomize/v3.5.4/kustomize_v3.5.4_$(OS)_$(ARCH).tar.gz | tar xzf - -C bin/ ;\ } KUSTOMIZE=$(realpath ./bin/kustomize) else KUSTOMIZE=$(shell which kustomize) endif

Notice the difference in how it is installed.

estroz · 2020-10-22T23:55:23Z

In Go's case it is installed in $GOBIN/kustomize. Is that intentional for some reason

If you're asking if Go projects need to install kustomize differently, then no. I'd like to see the non-go get download method implemented in the Go plugin upstream (related issue: kubernetes-sigs/kubebuilder#1351).

camilamacedo86

PS.: I checked that it is done for

So, it is fine to be done only for Go.

miguelsorianod · 2020-10-23T10:35:07Z

Regarding the binary location: I've taken a look at the related issue and I've found the following PR too kubernetes-sigs/kubebuilder#1711
Is that PR related to the issue?

If I can help somehow with this tell me. I'd be happy to contribute.

Thanks.

I've force-pushed content to reexecute tests, as continuous-integration/travis-ci/pr failed on the e2e tests for some reason. I executed them locally with make test-e2e-go and they've run successfully.

miguelsorianod · 2020-10-23T12:33:35Z

It seems travis tests failed again, but now on the ansible e2e test:

0.04s$ travis_setup_go gimme: given '1.15.x' but no release for '1.15' found gimme: given '1.15.x' but no release for '1.15' found Failed to run gimme The command "travis_setup_go" failed and exited with 86 during .

Force-pushed again to reexecute tests

camilamacedo86 · 2020-10-23T12:42:42Z

Hi @miguelsorianod,

Could you please rebase your PR with master and push it? Also, if some job Travis fails that has no relation with the changes in your PR not worry it is a flake and we can re-stat the specific job to get this merged. If you need please feel free to ping me in the slack as well.
