Installing prerequisite software

Before you install the IBM Z® Resource Discovery Data Service software containers, you must install the prerequisite software, which is either 1) Docker CE (Community Edition) engine, Docker CLI, and Docker Compose or 2) Podman.

Docker
If you want to use Docker and Docker Compose, but you cannot access the correct versions of the prerequisite software packages from the repositories of your Linux® operating system provider, you can use the convenience package docker_prereqs-v2.5.run that is provided on the Z Operational Analytics common components media. This convenience package includes the following prerequisite software in an easy-to-install form:
  • Docker CE engine 26.0.0
  • Docker CLI 26.0.0
  • Docker Compose 2.25.0
  • containerd 1.7.14
  • runc 1.1.12.
The package extracts itself and completes the following steps:
  1. It installs all prerequisites into the /usr/local directory.
  2. It creates a dockerroot user ID, if this user ID does not exist.
  3. It configures the Docker daemon as a systemd service, and it starts this service.

For more information, see Installing Docker.

Podman
If you want to use Podman, you must obtain it from your Linux operating system provider or from the open source ecosystem. Podman binaries are not provided on the Z Operational Analytics common components installation media.
