Question: SY0-701 Lab - Using Containers

Good day!

Need your input on the question from the SY0-701 Lab re: Using containers. The question is, "How do you enter a container session for 'MyContainer'"?

I understand that a container needs to be started first, before you exec it hence, docker start is the answer

However, there was no premise that was stated in the question, so many of the students thought that the answer is docker exec - based on the laboratory instructions.

Some may argue that the keyword at the end should be cmd however, powershell can actually be used in docker in real life scenario.

What do you think?

I did not known, if anybody that has been using can teach us it will be more helpful in this platform.

J,

Interesting point. I think you're calling out the difference between using and administering a container. I read that question as use the container app. I know some of my students who have taken the lab appreciated it as it broadened their knowledge (most never used containers before) and helped them understand how to administer a container. I had a student who used containerized apps in their job and thought that they were simply replaced by new containers when obsolete and appreciated seeing they could be maintained.

I'd suggest that all of us CertMaster instructors make sure we present this to students in class.

I agree. Container is really a good topic for the students.
I make it a point that the students understand containers in almost all certs - A+ core 2, Linux+, Server+, cloud+, network+, security+, etc

However, back to my question...
How do you enter a container session?
Which is it? docker start or docker exec?

Yes, that is exactly what I am asking.
How can we enter the container.
