Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Start by posting ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The offering manager team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notifications on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Please use the following category to raise ideas for these offerings for all environments (traditional on-premises, containers, cloud):

  • Cloud Pak for Multicloud Management

  • Cloud Pak for Network Automation - incl Orchestration and Performance Management

  • Cloud Pak for Watson AIOps - incl Netcool Operations Management portfolio

  • Edge Application Manager

  • IBM Observability with Instana

  • ITM-APM Products - incl IBM Tivoli Monitoring v6 and Application Performance Monitoring v8

  • Workload Automation - incl Workload Scheduler

  • Tivoli System Automation - inc Tivoli System Automation Application Manager (SA AM), Tivoli System Automation for Multiplatforms (SA MP)

Support for podman on RHEL8 for Self-hosted backend server

At this point, we are not planning to add support for hosting the Instana backend with podman.

The RHEL 8 docker package has been replaced by the container-tools module in RHEL 8 and some customers do not want to install docker-ce for RHEL 8 for technical or compliance reasons.

Technical, RHEL users have to choose RHEL 7 or other supported OS (e.g., CentOS, Ubuntu, Debian) that are not familiar with technically.
In a proof of concept situation, this sets the bar too high.

Compliance, RHEL 8 might be the only approved OS they have.

    As discussed by email briefly, we have customers in Canada who do not have other alternatives (security constraints, skillset, etc) but to use Podman. This makes it impossible to have POCs with a self-hosted backend Instana server.

    Also, I read in the comments "Alternatively consider our Kubernetes offering, which soon is going to support Openshift."
    What is "soon"? Do we have a date?

    Because opportunities with our customers for POCs leading to a sale are NOW. If we cannot have successful POCs due to our lack of support of Podman, which is the new standard on RHEL, we will lose those opportunities. And our competition will not.

    Is it possible to reconsider this position regarding podman? We have already to clients rejecting Instana due to the docker only support. I think that possibility of using podman for self hosted Instana would be great and bring possibility for clients not willing to use docker.

    Why don t we look into adding a support statement for docker EE which should be a question of certifying it as it is the supported version of Docker.

    You can run Instana on docker-ee there are no problems with that we know of and many self-hosted customers do so. Only issue for RHEL8 is there is only docker-ce (from the CentOS package repositories) for x86_64. See s390x

    So, what would be our position on the support for RHEL 8 (x86-64)?

    Bart, in addition to what we wrote via Slack DM. Our position on RHEL 8 remains unchanged. You can use docker-ce with RHEL8 or any of the other supported OS versions. Alternatively consider our Kubernetes offering, which soon is going to support Openshift.

    Why don t we look into adding a support statement for docker EE which should be a question of certifying it as it is the supported version of Docker. To me quite logical that Redhat and other OS vendors would not add official support statements for a community edition.

    After further research, docker-ce and docker-ee have the same support position for RHEL 8 on x86_64, i.e. unsupported. It's only supported on s390x.

    So, what would be our position on the support for RHEL 8 (x86-64)?

    Will the Instana server be supported on RHEL 8.4 with Docker EE? The docs only mention that Docker CE is a requirement.

    Unlike Docker CE, Docker EE IS supported on RHEL 8.4:

    After consideration in the team, I have to inform you that supporting podman for Instana Self-hosted will not be implemented in the foreseeable future.

    The reason is that our Self-hosted installer tightly integrates with the docker golang API that cannot be easily replaced as drop-ins like the docker cli.

    We see the value in continued support on these platforms. Therefore, will intensify our work on Openshift support and simplified Kubernetes onboarding. This will help you in proof of concept situations on these platforms.

    thank you for your suggestion. We added this feature request to our product backlog and will consider it in future planning.

    For now, please consider one of the following supported operating systems as per

    • Ubuntu 18.04

    • Ubuntu 20.04

    • Debian 10.x

    • Debian 11.x

    • Red Hat Enterprise Linux 7.9

    • Red Hat Enterprise Linux 8.x with Docker CE

    • CentOS 7.9

    • Amazon Linux 2.x

    • SUSE Linux Enterprise Server 12 SP5

    • SUSE Linux Enterprise Server 15

    You can still choose to install docker-ce for RHEL8.

    Please add any additional context you have here.
