Hi, I have just started with Docker only today and I have “beginner”. (hope this is right place to ask).
I have installed my first container like this: docker run -it ubuntu bash
Then I tried to install new package inside of docker container.
I follow some examples that I have google’d and it does not really work to me:
[root@centos7 ~]# docker run -it ubuntu bash
root@2869c7f4bb2e:/# apt-get install htop
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to locate package htop
What am I doing wrong?
