Assignments

• Check the curl version from two container, created from
• Cent OS 7
• Ubuntu 14.04
• Remove all these containers

Cent OS

Create container from Cent OS 7. Cent OS with version 7 can be found docker hub.

docker container run -it centos:7 bash

We can check curl version from bash by

curl --version

This return the curl version of 7.29.0

Ubuntu

Create container from ubuntu 14.04. The ubuntu image of version 14.04 can be found in docker-hub

docker container run -it ubuntu:14.04 bash

By default, the curl is not installed. To install curl, first update the packages by,

apt-get update

Now, install the curl by,

apt-get install -y curl

Since the curl is installed, check the version,

curl --version

We should get version of curl as 7.35.0.

Remove Containers

To remove containers, we can use

docker rm -f <cent_os_7_container_id> <ubuntu_14_04_container_id>

Apparently, If we used --rm flag while starting the container, we do not have to remove these container manually.
