ps command not found in fedora image in docker

Dec 10, 2016 Code

Docker is a lightweight virtual machine container. To minimize the image, most of the official distributions were erased most the unnecessary system tools.

After pulled the fedora, I found command "ps" not found in default. ps can be found in package procps.

Install command is very easy:

Bash

dnf install procps -y

@Donald The key point is you should install a package named as "procps".

dnf (https://fedoraproject.org/wiki/DNF ) is only for fedora 22+.

if you are using RHEL, you may use yum instead, if you are using ubuntu, you may use "apt-get"

In Docker images there's oftentimes only 'microdnf' available instead of 'dnf'.

That's good to know!

I used to use alpine instead to shrink the image, and when one project must use fedora, centos, rhel etc., the base image could already super huge.
