Start the container and connect to it:

[kamran@kworkhorse Qtbase-540_CENTOS-6664]$ sudo docker run -i -t qt540-centos6664 /bin/bash

Here we are inside the container:

Our prebuilt qtbase:

[root@4ffc2c8983b9 /]# du -sh /opt/qt/qtbase/

It is already on the network:

SELINUX is already disabled:

[root@4ffc2c8983b9 /]# getenforce
Disabled
[root@4ffc2c8983b9 /]#

Actually there is no /etc/sysconfig/selinux file on the system. That is why we don’t need to disable it in Dockerfile. If we try it exits with an error code and we cannot build a container.

Once finished working with it, here is how you stop it. 

Disconnect / detach from this session using Ctrl+p, Ctrl+q. 

DO NOT press Ctrl+c . Here is how it looks when you disconnect properly:

[root@4ffc2c8983b9 /]# [kamran@kworkhorse Qtbase-540_CENTOS-6664]$ 

Check images:
[root@4ffc2c8983b9 /]# [kamran@kworkhorse Qtbase-540_CENTOS-6664]$ sudo docker images

Check running containers:

[kamran@kworkhorse Qtbase-540_CENTOS-6664]$ sudo docker ps
CONTAINER ID        IMAGE                     COMMAND             CREATED             STATUS              PORTS               NAMES

[kamran@kworkhorse Qtbase-540_CENTOS-6664]$ 

Stop running containers:

[kamran@kworkhorse Qtbase-540_CENTOS-6664]$ sudo docker stop fervent_bardeen
fervent_bardeen

[kamran@kworkhorse Qtbase-540_CENTOS-6664]$ sudo docker stop compassionate_mccarthy
compassionate_mccarthy

Check if there are any running containers:

[kamran@kworkhorse Qtbase-540_CENTOS-6664]$ sudo docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

The images should still exist (of-course):

[kamran@kworkhorse Qtbase-540_CENTOS-6664]$ sudo docker images
