YAML is one of those files your going to be running into a lot in your IT Career! Smash that like button if this video helped you.

Great tutorial. At about 3:58 in the video, there is a loud pop or crack which scared the heck out of me.

I've become a fan of TOML over the past few months. I used it for the settings of my scripts. I think it's the best for readability amongst the other file types, JSON and YAML. Maybe I'm just old and use to the ini days with Windows. Your video helped me understand YAML, though.

Your explanation is the best from all YT man. Congrats!

Really nice and simple explanation. Can you please make some video on what kid of rights user need to run Dev Ops powershell script on remote server, to create the environment?

Can you make a video about your suggestion channels, please? Like your channel, it is amazing but you deserve more subs.

Thanks for explanation video. I think it would good if you clarified is it a line break that is signalling end of value? Also, are the indentations required or just being used to improve readibility? If they are required are they spaces or tabs?

Thanks for the video, this is really helpful. I am just starting to learn yaml. In the docker-compose.yml file line number 5 and 6 why should ports value should be represented in such a manner where the same port number is repeated with a colon in between and surrounded by quotes - '8086:8086'

[mehrandehghan]

Thank you, but I think it was not enough. it would be more better if you could explain which lines are dedicated for dictionaries or for example why they have used lists for ports and ...

(yaml: line 71: found unexpected end of stream) can u solve this issue????

[arunareddy]

Can you please make vedio for how to validate yaml files and what are the different tools we can use to validate yml files.Recently i got a requirement in my project like we need to validate yml files and that logic should merge with buildpipeline and if we have any invalid syntax my build pipeline should fail before we merge code to master branch. I searched many examples in net but most of them i found in python scripts since i am not familiar with python script i am looking examples in Java.

Could you please share one example codefresh yaml file to upload multiple files to artifactory

[JainmiahSk]

We use YAML for Config files or for Data preprocessing and Machine Learning also?

[aminghanooni]

May you explain this part which you ran in Terminal: "Python .\read_yaml.py myfile.yml"? I do not get how this part works ----> .\read_yaml.py myfile.yml. Does it run two files simulatneously? Thanks if you can elaborate on this!

[rakeshkanna]

hi, can you help me to find the difference between two YAML files and display the difference in HTML format ?

[briangeraghty]

I'm getting an error in the python script "Import "yaml" could not be resolved from source Pylance report (MissingModuleSource)"
and
Import "rich.console" could not be resolved Pylance (reportMissingImports)

I believe it's stopping me from running the script as It is saying there is no such file in the directory.

Any idea what's giving the errors? Could it be my plugins?

[gabrielfono]

I still don’t understand what pb yml solved when we could still use json to resolve the issue
Basically,
Please could you make a video about why yml is important over other file type like json for instance
Thanks
