How to install ps in redhat ubi8/ubi-minimal

Question

For registry.access.redhat.com/ubi8/ubi-minimal this image, i need ps utility to be installed. There is no yum package manager available in the image. Instead , we have microdnf.

microdnf install procps says there is no such package named procps

Singlephase

Answer 1

In the Dockerfile, add the following statement and you should be able to use ps

 RUN microdnf update && microdnf install procps

Singlephase

The baggage this package brings with it, is surprising. I simply refuse to believe that "ps" requires "cpio", "cracklib", "systemd" and others. – Conni

Upvoted for the info for using RUN microdnf update && microdnf install due to the absence of yum package management – Barman

Answer 2

The package name is procps-ng

In ubi8/ubi: yum install procps-ng results in downloading one package, 389kB.

Similarly for ubi8/ubi-minimal: microdnf install procps-ng
