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:

dnf install procps -y

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.

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

    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”
