lua-rover issue faced while enabling support for power(ppc64le) architecture

[shubham-bhagwat0]

issue:
openresty image is built from scratch for power,
and the "make development" command is working fine, a runtime container is getting created,
but inside the container, when we try to run "make dependencies" command,
it gives the following error:

bash-4.4# make dependencies
make: *** No rule to make target '/usr/local/openresty/luajit/bin/rover', needed by 'lua_modules'.  Stop.

furthermore, we made the necessary changes required to build lua-rover in the Dockerfile (openresty) but it still eventually fails at the very same error

another issue faced is :

1. we imported the custom openresty image by making changes in the "docker-compose-devel.yml" file
2. later we realized there's another image which is required by the "docker-compose.prove.yml" file which has the name of {IMAGE_NAME:-apicast-test}
   which is supposedly required to run the test cases

Version - v3.15.0

Steps To Reproduce

• create custom image specifically for power architecture (ppc64le)
• import the image in "docker-compose-devel.yml" file
• run make development and run the further commands inside the container during runtime

Current Result

3scale/APIcast$ sudo make development

Hi, it looks like you don't have rover installed in your image. What command did you use to build the runtime image?

For development image, you will need to run make dev-build IMAGE_NAME=quay.io/3scale/apicast-ci:openresty-X.Y.Z-{release_number}, then reference that image inside docker-compose-devel.yml

image: ${IMAGE:-quay.io/3scale/apicast-ci:openresty-1.19.3-23}

NOTE: you will need to modify Makefile to build for ppc64le. The default is linux/amd64

dev-build: ## Build development image
   $(DOCKER) build --platform linux/amd64 -t $(IMAGE_NAME) \
      --build-arg OPENRESTY_RPM_VERSION=$(OPENRESTY_RPM_VERSION) \
      --build-arg LUAROCKS_VERSION=$(LUAROCKS_VERSION) \
      $(PROJECT_PATH) -f $(DEVEL_DOCKERFILE)

hi,
we tried to build it further and we are facing the jaegertracing issue

jaegertracing issue:

• not initially supported by power
• but it can be built and integrated as a custom build for ppc64le arch
• tried building and integrating it, ends up failing one of the test cases
• and it is also deprecated and no longer being maintained

custom jaeger build leads to the following error :

alternatively:

• the community has already suggested to use opentelemetry
• plus we've noticed the use of openresty-opentelemetry
• so should we just replace jaegertracing with opentelemetry??

Hi,

This test doesn't look like APIcast test suite so I can't comment on what's wrong with it. But if I had to guess, I think your jaeger-client-cpp is not built correctly, thus leading to failed DynamicallyLoadTracerTest

Regarding jaegertracing, it will depend on your use case, but you are right, we are gradually moving to opentelemetry and keeping support jaegertracing mainly for those who have not yet migrated to opentelemetry. However, we will eventually remove jaegertracing in a future release.
