Allow running Deployer on Power

[fketelaars]

In CP4D 4.8, broader support for Power is available. Allow deployer to run on Power.

Hi Frank,

If I could help on this, don't hesitate.
I quickly try to rebuild the container, but some product seems to be hardcoded to x86.
helm and some other are available on ppc64le, but I have some difficulties with openjdk-9.

Can we use openjdk-8 or other version (11,17,21) which are supported and can be easily setup with yum/dnf ?

I can provide remote access to an openshift on Power if needed ;)

Hi @schabrolles I made some initial changes to remove the Dockerfile x86 dependencies. Java and helm are only needed for CP4BA, hence deployer now only installs them if CP4BA is seelcted. Additionally I have removed olm-utils (v1) image from the Dockerfile as there is no Power version of it.

I would appreciate if you can test the changes in the deployer-power branch on your cluster.

Hi @fketelaars

I make it work after some cleaning anf changes:

1. in the Dockerfile:

• Use a non-official valut port for Power (hashicorp doesn't provide them)
• Add gcc and python devel to rebuild missing python dependencies during pip install
• Workaround to build wheel due to some cython and PyYaml issues

2. Fixing some hardcoded x86 binary download in shell script and Ansible

• Create an ARCH variable (using uname -m) in order to automatically set the right arch when downloading files.

a container image is available here: quay.io/schabrolles/cloud-pak-deployer:latest

I've already tested it to deploy CP4D 4.8.3 with DB2 OLTP on Power, but we should share it with others for further testing.

Thanks @schabrolles , that is great news! Will pull in other resources who can test as well.
