Ubuntu support

[kaovilai]

We want to be able to start and run microshift from ubuntu which is used by many ci systems.

@kaovilai, we are not planning to support Operator Lifecycle Manager (OLM) with MicroShift.

Operators may still be installed if they do not require any OCP APIs unsupported by MicroShift. You should inquire with the OADP team if non-OLM installation is possible/supported.

@ggiguash I am part of the OADP team and we are investigating ways to get around 40minute install time for e2e testing if possible. Microshift is one of the possible avenues to explore.

Looked into Hive cluster but it seems like we may not have enough permission there to install operators unless we make our own hive.

Please, review the list of OCP API supported by MicroShift at https://github.com/openshift/microshift/blob/main/docs/enabled_apis.md.
We have no plans to enable OLM support in the foreseeable future.

Let's close this issue, unless there is any further questions on OADP installation without OLM.

[kaovilai]

We are not worried about OADP installation specifically. This issue is not regarding any operator installation or OLM. The ask is simply, can we have something like kind create cluster for microshift.

If you have go (1.17+) and docker installed go install sigs.k8s.io/kind@v0.17.0 && kind create cluster is all you need!

I am not asking for additional API support, OLM support, OADP support from microshift.

I am asking that microshift be as easy to install and up and running ready for kubectl/oc like kind cluster

[kaovilai]

specifically on non RHEL systems that are used by travis-ci/circle-ci if possible.

[kaovilai]

I hope title change clear up the minimal requirements.

Hey,

I'm not sure if Ubuntu support makes a lot of sense for this project. Microshift is a project build for the Red Hat family of operating systems. Designed to be a light weight, edge worthy deployment of OpenShift and ideally run on os-tree bistro deployments.

In that regard, I'm not sure the mission of the Microshift project would include support for multiple Operating Systems. I understand what you're saying about upstream CI environments. But I don't think multi-OS support is something this project is pursuing.

With regards to kind-like deployment that can be up and running quickly. Have you tried Code Ready Containers?
https://github.com/code-ready/crc
https://developers.redhat.com/blog/2019/09/05/red-hat-openshift-4-on-your-laptop-introducing-red-hat-codeready-containers

Maybe that would be better suited for your use case?

@kaovilai, At this time, we only plan supporting MicroShift on RHEL 8.x and, later, RHEL 9.x OS. Furthermore, due to the nature of the project, we are not planning to support container-based bootstrap for MicroShift. All these for downstream activities.

When upstream activities are resumed, it is likely that CentOS and Fedora are going to be used by the community.

Overall, the only configuration we can offer for running MicroShift on Ubunty is to bootstrap a RHEL VM and run MicroShift in it. An example of such a quick-starter can be found at https://github.com/openshift/microshift/blob/main/docs/getting_started.md.

CRC do not work.
https://app.circleci.com/pipelines/github/kaovilai/reliable-ci/15/workflows/e65e2e00-0e06-44da-9598-a0d1a0e593a3/jobs/22

[kaovilai]

Microshift had Ubuntu install scripts previously iiuc but later removed.

I just need a flavor of openshift that runs in Travis/circleci. Point me to one if you know anything that works ☺️.

[kaovilai]

Apart from specific distribution support.

kind cluster support any environment with a valid docker and golang install.

Not so microshift.
