Route Laucher not found on PPC64LE

sarveshtamba commented 5 years ago

I am following the steps at:- https://github.com/fabric8-launcher/launcher-operator

Facing the following error at step 4:-

[root@p006vm32 launcher-operator]# oc get route launcher --template={{.spec.host}}
Error from server (NotFound): routes.route.openshift.io "launcher" not found

Investigated the same and found the following:-

Hi, any help on this one would be greatly appreciated. Thanks in advance.

sarveshtamba commented 5 years ago

@ia3andy are you the right person for this issue? For fabric8/launcher-operator deployment I am facing "CrashLoopBackOff" for the pods.

In the file "deploy/operator.yaml" the image used is as below:- image: fabric8/launcher-operator:latest However, the latest fabric8/launcher-operator image has ARCHITECTURE=amd64 and OS=linux(https://hub.docker.com/r/fabric8/launcher-operator/tags), so we might need to build the image for ppc64le first and then continue the deployment using the built image.

Can you please confirm if this is the correct understanding?

sarveshtamba commented 5 years ago

I tried to build the image for ppc64le using steps in Develop section and it got built successfully with the operator-sdk build command.

However, the pod is still in "CrashLoopBackOff". On investigating found that the build/_output/bin/launcher-operator gets generated for x86_64 while the build/_output/bin/launcher-operator-local is for ppc64le.

[root@p006vm32 launcher-operator]# file build/_output/bin/launcher-operator*
build/_output/bin/launcher-operator:       ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped
build/_output/bin/launcher-operator-local: ELF 64-bit LSB executable, 64-bit PowerPC or cisco 7500, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=2d72ea8c8d958d1865d7c45ea3a180cbad9c0ec1, not stripped

Investigating further on this.

Resolved the issue wherein 'launcher-operator' binary used in the image gets generated for x86_64 by default, by setting GOARCH variable for ppc64le arch as below:- export GOARCH=ppc64le

Cleaned up and built the image successfully with the operator-sdk build command, post which the Launcher operator got deployed successfully.


[root@p006vm32 launcher-operator]# oc get all -n launcher-operator

- Currently working on step to Install the Launcher (via the installed operator). Facing issues with the example launcher yaml which makes use of image: fabric8/launcher-backend:latest, which for now is available for x86_64.
