arm64

[faust64]

Hi,

I'm trying to install ltb-openldap, on a Raspberry Pi -- Raspbian (arm64) -- and could not find any package.

# uname -a
Linux xxx 5.10.4-v8+ #1389 SMP PREEMPT Wed Jan 6 13:52:18 GMT 2021 aarch64 GNU/Linux

It would be nice to have ltb-openldap released on arm64. And maybe even 32b arm. Same goes for rpm packages. Might be able to work on this, if I can figure out how to build something similar to official packages ....

Thanks.

Hello,

some documentation here: https://github.com/ltb-project/openldap-deb/blob/master/debian/paquet-openldap-debian/packaging_debian.README

Would be indeed great to have packages for ARM, but this requires to have a build platfrom for every new release

Would be nice indeed.

For new fresh release 2.4.57 it will be complicated to have this. @faust64 if you have worked on this, we could assess if we can integrate it for future major release 2.5.

Maybe building all archs from the same host would be preferable? Though it would require extra work, setting up multi-arch. In cases you're amenable to build packages on arm machines directly (raspberry, rock64, odroid, ...), then there's nothing to change to the existing assets, really.

I used Tekton Pipelines (a Kubernetes operator automating CI/CD jobs). First, you would create a Tasks, describing how to build your package, and what to do with it once built (eg: push to a nexus repository) :

Next, describe a Git PipelineResource, serving as an input, pointing to this repository:

apiVersion: tekton.dev/v1alpha1
kind: PipelineResource
metadata:
  name: openldap-ltb-deb-2456
  namespace: ci
spec:
  params:
  - name: url
    value: https://github.com/ltb-project/openldap-deb
  - name: revision
    value: v2.4.56
  type: git

Then, a Pipeline, listing a sequence of tasks (we could also have added tasks scanning code, running tests, ...)

apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
  name: build-ltb-openldap
  namespace: ci
spec:
  params:
  - default: 2.4.56
    description: OpenLDAP Version to Build
    name: ldapversion
    type: string
  resources:
  - name: app-git
    type: git
  tasks:
  - name: build
    params:
    - name: ldapversion
      value: $(params.ldapversion)
    resources:
      inputs:
      - name: source
        resource: app-git
    taskRef:
      kind: Task
      name: deb-build-ltb-openldap

Finally, start the job by creating a PipelineRun, that would associate our Git PipelineResource to our Pipeline, as well as passing an OpenLDAP version param:

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
  name: ltb-openldap-2456-1
  namespace: ci
spec:
  params:
  - name: ldapversion
    value: 2.4.56
  pipelineRef:
    name: build-ltb-openldap
  resources:
  - name: app-git
    resourceRef:
      name: openldap-ltb-deb-2456

Tekton is definitely not mandatory. If you have some Kubernetes with both x86 and arm nodes, it could be interesting. Otherwise you'ld be better just proceeding as usual, on any ARM host you have available.

as a follow-up, I'm now building ltb-openldap for debian 10 / aarch64, using GitLab CI:

https://gitlab.com/synacksynack/opsperator/docker-openldap/-/blob/master/Dockerfile.ltbsrc-deb10 https://gitlab.com/synacksynack/opsperator/docker-openldap/-/blob/master/.gitlab-ci.yml

In your case, there may be a way to use something like this, and instead of shipping a container image, just copy its packages to some volume, outside that container, once done building. Which would spare you from looking into RPI-lookalikes, or other gcc multiarch specifics, ...
