Day-5 | Most Common Terraform Task Used in Real-Time |

[@abhinaisai4778]

running a web server is long running process. terraform doesnt know whether it is successful or not. It terminates the command while closing the ssh session. We should run the process background and give some prompt to the terraform. I think we can do it using the nohup cmd

[@AbhishekVeeramalla]

😎😎

[@Geekgurlcode]

I am a beginner..can you elaborate more?

[@Deva2596]

@@Geekgurlcode When you run a Terraform script to provision infrastructure, certain resources may involve long-running processes, such as deploying and configuring a web server. The issue you're encountering is that Terraform may not wait for these long-running processes to complete before closing the SSH session, leading to uncertainties about whether the process was successful or not. One approach to address this is to run the long-running process in the background and disassociate it from the current session. The nohup command is a useful tool for doing this in Unix-like systems. The nohup command stands for "no hang up" and is used to run a command immune to hangups, with output to a non-tty (non-terminal) that persists even after the user logs out.

[@suhasdhoke1735]

as we run any command with "&" at the end , it run the command in backgroud , nohup is just for getting output of the commands in nohup.out files at same location.

[@ajayhegde2761]

​@@suhasdhoke1735 I am also thinking the same. It should run in background right as we are using sudo command and & at last it should work. I searched and got this. I am not sure Shell Differences: The shell environment might behave differently between manual login and remote execution. Try explicitly setting the shell to /bin/bash or /bin/sh in your remote-exec command to see if it resolves any differences.

After watching thiese video getting some questions in my mind. What is difference between tf and ansible? Upto packages installations the tf provisioners are Ok but in real time projects using more than that so how it will useful ? By using ansible we can manage all hosts/servers to different operations like installations/copy etc..

[@sowmithrawulwar2823]

I wish you could've used modules and backend concept in this video and explain it, Integration of concepts are missing. It would've given more clarity because when we use different concepts or previous topics , things will be real time and gives good knowledge.

[@bogathiparthasarathireddy4487]

Hi @AbhishekVeeramalla Thanks for giving wonderful Terraform series to learn free in KZbin. I have find clear cut solution in google "To run a shell script in the background, use the “&(ampersand)” bash control operator and the built-in “nohup” command line tool. Both these utilities almost perform the same job. The core difference between both of them is that the “nohup” command does not kill the background process at the session termination while the “&” symbol terminates all processes after the system logout" this is the correct solution for your assignment i think. If anything missing. Could you please suggest . Thanks in advance!!

[@nishanbaral5124]

Yes. the last line should be replaced with this "nohup sudo python3 app.py > /dev/null 2>&1 &" This will also run the app in the background and discard all output-error log of the app. Doing this it won't kill the process while session termination.

Using wget in remote-exec and its not working. Replaced it with Curl still same problem. The instance is created. All commands before wget get executed, but when it comes to wget or curl, it shows creating and this goes on for infinity. Tried ssh into the same machine and ran the command from the console. It runs perfectly. That implies that this is not a problem of ports. Then what am I missing, or what is the solution if I want to copy a file into my created instance.

[@Sasmita-c8z]

The same thing happens in the demo in this recording when running python app, when going to the instance running that command it's working perfectly, but from remote_exec, it is not, if we remove the '&' at end it is running fine, but again it shows creating infinitely..., it is dificult to debug what's going wrong. @Abhishek, do you have any input here?
