I have a project deployed on EC2 instance and is up.
But sometime when I login through FTP and transfer the updated build to the EC2, some of my project file gets missing.
After a while those set of files is seen listed at the same place.
Couldn't relate why these unexpected behavior is happening. Let me know if anyone has faced similar kind of situation.
Or anyone can give me a way to know what all logins are being done through FTP and SSH on my EC2.
Files don't just randomly go missing on an EC2 instance. I suspect there is something going on and you'll need to diagnose it. There is not enough information here to help you but I can try point you in the right direction.
A few things that come to mind are:
What are you running to execute the ftp command? If it's appearing after some time, are you sure it's just not in progress when you first check then it appears when it's done? are you sure nothing is being cached?
Are you sure your FTP client is connected to the right instance?
Are you sure there are no cron tasks or external entities connecting to the instance and cleaning out a certain directory? You said something about the build, is this a build agent you're performing this on?
I highly doubt it's this one but: What type of volume are you working on? EBS? Instance Store? Instance Store is ephemeral so stopping/starting the instance can result in data being lost.
Have you tried using scp ?
If you're still stumped, please provide more info on your ec2 config and how you're transferring the file.

So, I picked up an old project to maintain and don't have much context for it. But I need to access the machine to remove some files there that r causing errors on npm install. But, when I did enter the Google Cloud Painel, the server is running on the website but had no instance running. I don't know much about Google Cloud, so how its possible that the instance is not appearing to me? Even tho I know that exists and appears some information, but I wasn't able to find a way to access it, someone can help me? If it's too hard to explain here, we can find a way to talk.
You can see that has "Create Instance" on the button
So I've recently joined in a project. They asked me to develop a particular module so I did. Now I need to integrate it with the system. They gave me AWS login credentials for the integration purpose. I'm new to AWS and I don't wanna sound dumb to them by asking where's the code. I saw that there's an EC2 instance running but I see no option to see code there. So can you please let me know where can I see the code of running EC2 instance?
Never feel dumb about asking questions on your team. It's much better to ask questions and seek clarification, rather than assume and waste your time and theirs.
So if your team is tasking you with integrating a module you've built with something running on EC2, they probably have an API of some sorta to integrate. They likely aren't expecting you to go to EC2 and view code or decompile DLLs to view source code.
However, to potentially answer your question if your EC2 instance is running some sort of application that has DLLs, you can download those and decompile them using various tools to view the actual source code. YOu would of course need the keypair to access the EC2 instances so you'd have to get that first.
I would just ask someone on your team how to integrate with the system running on EC2. They likely have the source code stored somewhere in a repository.
I am having some of my GCP instances behave in a way similar to what is described in the below link:
Google Cloud VM Files Deleted after Restart
The session gets disconnected after a small duration of inactivity at times. On reconnecting, the machine is as if it is freshly installed. (Not on restarts as in the above link). All the files are gone.
As you can see in the attachment, it is creating the profile directory fresh when the session is reconnected. Also, none of the installations I have made are there. Everything is lost including the root installations. Fortunately, I have been logging all my commands and file set ups manually on my client. So, nothing is lost, but I would like to know what is happening and resolve this for good.
This has now happened a few times.
A point to note is that if I get a clean exit, like if I properly logout or exit from the ssh, I get the machine back as I have left, when I reconnect. The issue is there only when the session disconnects itself. There have been instances where the session disconnected and I was able to connect back as well.
The issue is not there on all my VMs.
From the suggestions from the link I have posted above:
I am not connected to the cloud shell. i am taking ssh of the machine using the chrome extension
Have not manually mounted any disks (afaik)
I have checked the logs from gcloud compute instances get-serial-port-output --zone us-east4-c INSTANCE_NAME. I could not really make much of it. Is there anything I should look for specifically?
Any help is appreciated.
Please find the links to the logs as suggested by #W_B
Below is from 8th when the machine was restarted and files deleted

It happened again today. I didn't run the command immediately then. The below file is from afterwards though

The below one is after logout today.

Please note that I have replaced the user id, system name and a lot of numeric values in general using regexp. So, there is a slight chance that the time and other values have changed. Not sure if that would be a problem.
I have added the screenshot of the current config from the UI
Using locally attached SDD seems to be the cause ... here it is explained:

You need to use a "persistent disk" - else it will behave just as you describe it.
I have set up an elastic beanstalk deployment of Drupal to host a Drupal built website.
When I start up my ec2 instance, I go through the installation steps of setting up Drupal.
However, when the instance is Restarted, or Stopped, restarting the instance goes back to this page!
How can I configure the instance so that these installation steps do not need to be repeated even when the instance goes down. This is quite worrying as I am looking to host my website this way.
Any help on this issue would be greatly appreciated!
This step means that drupal can't find database or it can find it but installation is not done yet (required tables are not created). So if you pass installation and you see again this screen it can mean 2 things:
Your database configuration is lost, so drupal can't find DB.
DB configuration file is ok, but DB it self is lost so configuration must be done again.
So first check what is the problem in your case and then solve it. Probably since you are installing in instance, DB configuration is then recorded and then lost when your box expires. If so...find a way to make permanent change do config file (should be /sites/default/settings.php).
So here's the deal, I'm trying to run a little webmail server for testing purposes off amazon's EC2 server, I'm looking at their guide for setting the hostname, and the directory they mention /etc/sysconfig/ doesn't exist, let alone the file I'd be expected to edit, when I go to the actual hostname file (as if I was running the server) cd /etc/ then nano hostname I can read but I don't have write permission, so when I go to save the file it tells me I don't have the permissions, so I looked it up, and it says to edit /etc/sysconfig/network which would be fine and dandy, if the directory actually existed. Pretty new to all of this, so if I missed anything that could help you figure out what's going on please let me know! Thanks in advance!
It sounds like the base AMI you are using for your instance is not one of Amazon's AMI's. What AMI is the instance based on?
