[@giuliavalentini6563]

I have cleared the RHCSA exam a couple of weeks ago and your videos were the best I found on YT for review and for practice. I would like to suggest sharing similar content for the RHCE exam, I'm sure many of us would be extremely grateful!

I like the way you break it down by talking of the first part, second part,....and other ways of doing the same thing. Thank you very much. Remain highly favoured in insight and strength you often take to make this a possibility. Thank you.

[@dextutor]

Glad it was helpful!

Thanks for this. I'm studying for my RHCSA and the one area I was having trouble finding study materials for was containers.

Welcome

[@heronfa]

Thanks for your video. I have a question. I'm trying to run a container with a mount directory, so I did the command with -v. Later, when I ran podman ps -a, the status of the container was EXITED. Do you have any idea of why is doing that?

[@dextutor]

Can you mail the snapshots

[@heronfa]

@@dextutor I Just sent the snapshots to your email. Thanks for your help.

[@talitasoma]

Excellent video, congrats and thank you!

[@dextutor]

Thanks

[@fahimahmedvlogs]

The mapping doesn't work with SELinux on so put -v /web:/path/of/container:Z to avoid the error

[@nawsan5556]

Thanks it works

[@rehmanarshad1848]

Thanks man, it works!!!

[@sainumediacreations532]

Please add a devops tool section or aws course

[@pippoincazzat]

I've noticed that during exam, you use a different version of podman (1.6.4) instead the 4.1, and running it as a service it's impossible. Any suggests?

[@SilentSolution]

Thanks for your video ..

[@dextutor]

Most welcome

[@MrEjo14]

Run sudo chcon -Rt svirt_sandbox_file_t /web2 if you have any error codes with 'ACCESS DENIED' via curl. SELinux could stop you from accessing the mapping file.

[@nanthinimaravarman6269]

Podman search rsyslog also

[@wernyny2222]

Can we use docker as well or only podman?

[@dextutor]

No

[@subhankarmaji4355]

Sir on 24th March I'm going to give rhcsa exam... But nervous on container question.... In exam what ques will be straight forward or complex?

[@dextutor]

All the best.. If you have understood the basics it would be easy

Hello. What should we do in the case that a container image is not specified in the task?

[@dextutor]

They will specify

[@debunker_letsGO]

I am still lost when it comes to containers.....my oracle vm rhel 9 server doesn't give the access like your. e.g podman run -it ..... it just tries to download the latest thing. and nothing....

[@christianchapoco5472]

Hi, when i curl the webpage mypage.html, it says i dont have permission, where could this be coming from? im already in root. thanks!

[@fahmedsa]

How to make these containers and their settings persistent on system in exam. So that they will be run after reboot. Also how to podman login persistent etc?

[@dextutor]

Need to see how you are doing it..can discuss over video call

hello sir, during the practice how to get/create the username and password to entering the docker register

[@dextutor]

Register with docker

[@Jim892]

@@dextutor thank you. My redhat login worked here.

[@MatteoMagri]

I followed your tutorial to map an external folder to the container in order to reach the file mypage.html but every time I try to retrieve it by curl or by browser I get error 403 - Forbidden - You don't have permission to access this resource.

[@MatteoMagri]

Found why... with SeLinux enabled, i should put -v /web:/usr/local/apache2/htdocs:z and it work. The way is add :z at the end of folder destination.

[@dextutor]

Great

[@mmanzur]

I am having an error "you dont have permission to access this resource" I have changed 755 for local folder but it is still not working

[@nawsan5556]

I had the same error that I don’t have permission to access. I chmod 777 the folder in the localhost but still got the error

[@nawsan5556]

I got the answer from the other learner, podman run -d -name web1 -p 8080:80 -v /web:/container/path:Z imageID

[@aralam5923]

Dear Sir, Yesterday my friend exam EX200 RHCSA , but i want know, container part is mandatory for pass RHCSA exam? My 3 friends recently RHCSA exam, but 3 friends are didn't answer container questions part, here 200 score got all friends but how it possible all are same result,

[@dextutor]

Every question carries different marks.. In total you need to score 70%. So you can get some questions incorrect as long as you score 70%. Also, the result shows which sections you got correct and which ones not. So that can help you analyse you weak areas

[@Gamma_Wale]

Hi i have one doubt, if our Linux os crashed then how recover files

[@dextutor]

Use any file recovery software

Change SELinux to Permissive

[@gabrielefrusin4785]

@@dextutor sorry, it wouldn't be better to manage se SELinux context to apply to the directories and files?

[@mariaangeles3112]

@@dextutor Thanks that works!

[@MRP4U2B]

You need to add the selinux context to the /web directory on your VM or Laptop using RHEL Linux (outside the container): # semanage fcontext -a -t httpd_sys_content_t "/web(/.*)?" then run: # restorecon -RvF /web For more details check the examples section of # man semanage-fcontext Then check again: # curl localhost:8081/mypage.htm it works now 🙂!!!

[@markogilo5332]

@@MRP4U2B the podman docs says you should not relabel. It gives some options like adding a :z to the end of the container path or using the --security-opt label=disable option
