I'm running the headless Dropbox CLI on a linux EC2 VM, works fine. I have created an AMI from my VM and created a new instance. Dropbox CLI starts and reports syncing, but it's not syncing. I suspect I need to re-initialise the client to create a new context between it and my account for this instance but I can't find any documentation on how to do that. I probably just need to remove a file and restart the client, but what file?
Delete ~/.dropbox

Can I use AWS Lightsail's Launch Script option to upgrade Wordpress/LAMP upon creation?
Lightsail saves time and ports to EC2 if needed.
Sadly, it loads an old versions of wordpress and LAMP.
The option to add a launch script when creating a new instance would seem an ideal way to create an up to date site. A fresh instance followed by a simple site migration would save hours of updates.
If you can script the upgrade, you can use the launch script. But, I'd argue that's not the best way to solve the problem.
Bitnami images use a different directory structure than a "normal" WordPress installation, so getting all that correct could be a hassle.
It would likely be faster to just boot an Ubuntu (or whatever) image and use the launch script to install the Apache, PHP, and WordPress versions you want.
I am running a python machine learning script on google cloud platform. I have connected through SSH in browser. When I run the code it works, but when I close the browser it seems to stop running.
I believe I can make it run in the background with nohup, but I want to be able to check back in on it as it prints outputs on its progress.
Basically I want to be able to start the script, close the terminal and then reconnect from any machine to check on its progress. Any help would be really appreciated.
I am new to google cloud platform if any of this was unclear please as an ill try providing more detail.
You may use an app called as screen. Just install it using `sudo apt-get install screen`` (if debian, ubuntu).
In some cases it might be already installed in your instance, you may check it.
Once installed enter the following command into the terminal:
screen
and press enter. Now, You may start with your job in terminal.
The moment you need to disconnect you may press Ctrl+A and then d.
The session would be disconnected. You may note the session id that would be displayed (eg. detached from 1498.pts-1.server)
You may now close the terminal.
When you come back, use the following command to get back into the older session.
screen -r *screen_id* (eg. screen -r **1498.pts-1.server**)
This process is checked for google cloud, ssh through browser, it really works.
Check this site for mode details.
It sounds like you're referring to the Google Cloud Shell feature. If so then what you desire is not possible, the cloud shell is not intended for non-interactive operation. From Usage limits:
Cloud Shell is intended for interactive use only. Non-interactive
sessions will be ended automatically after a warning.
The cloud shell operates on a temporary Compute Engine virtual machine, which is running only while the cloud shell session is active in the browser.
Apart from the obvious approach of keeping the browser session active while your application is running, you could also provision yourself a non-temporary Compute Engine instance (a free one is available), to which you can connect and on which you can run non-interactive applications as you desire.
A selenium script , when executing from Eclipse in a local machine , clicks an UPLOAD button in browser to upload some files from local machine to that application running in browser.
This uploading part is failing when the script is executing from Jenkins because Jenkins server is unable to access local machine.
Any idea how to overcome this issue..??
Accessing these files from the server is a bad idea (unless it's a Jenkins's slave) though can be achieved via your code or some CMD tool, with providing the address and credentials. Put some effort in this and you'll find how to do it...
The better solutions will be adding these files to the Jenkins server as well or committing these files to your repository and checkout them before the test.
A shared folder could also do the trick on a filer type server or similar.
Hope it helps. Anyway there's no substitute to your own research e.g. Google and StackOverflow.
I have used Click to deploy MEAN Stack on Google Compute Engine. Everything is fine, runs in the Cloud and on my local machine.
When I try to browse source code in the developer console, I get the Getting startet screen for cloud source tools.
Should it not be set up automatically when I created the instance?
When I SSH into the instance I can see the content of opt/myApp.
This I would like to see in browse source code also.
If I try to git clone the Cloud Repository it is empty.
I'm currently using the trial version. Maybe this is the reason I can not browse or clone the Cloud Repository?
This is a really good suggestion. It would be very interesting to integrate click to deploy in more Google Cloud Platform services. The MEAN click to deploy doesn't have much of a sample application installed, which is why it doesn't make sense to put it in a code repository. The application stack itself (mongo, express, angular, node) you wouldn't put in a repository, which is really the only thing installed on the MEAN Click to Deploy server.
If you look at the Linux ecosystem (especially the Ubuntu and Alestic EC2 images) there is a common technique where the VMs are pre-configured to look at the EC2 user-data and use it as a boot script. The nice thing about this approach is that you can write a boot script that further provisions your machine, allowing you to avoid making a new image every time your software that runs on the machine changes.
I want to do the same thing for Windows, but given that I'm an Mac and Linux guy, I'm a bit lost on where to start. My requirements are:
This must run on Windows Server 2008
A bootstrap script needs to start when the machine boots up, read the user-data file by pulling down the contents http://169.254.169.254/1.0/user-data
The bootstap script then needs to run the contents of that file as if it were a script
The script embedded in the user-data needs to run in such a way that it has access to the desktop environment (ie: it can launch a browser, etc).
I'm not quite sure how services work in Windows or if I need to enable auto-login, so any advice here would be appreciated. The ultimate goal is to run a Java program that launches some custom software that in turn launches a web browser (IE, Firefox, etc) and is capable of taking screenshots.
The screenshot part is interesting, because in the past when I've tried this the only way I could get something other than a black screen was to have UltraVNC or RealVNC boot up as a service, though I don't know why that helped.
I'm looking for answers to three specific questions, as well as any general advice:
Should I be focussing on a Windows service or auto-login + bat file in the "Startup" folder?
If I use a Windows service, is there anything special that I need to do to make sure desktop access and/or screenshots are available?
Do you recommend any tools for common Linux commands, like curl or wget? Last time I used Windows I used Cygwin a lot, but is there something more appropriate to use here?
I have not tried auto-login on Windows instances in EC2, but here's the support document on how to enable it.
We boot-strap our Windows instances using a custom AMI with a custom Windows 'install' service already installed. The boot-strap installer reads a URL from user-data at startup. The URL points to a ZIP file stored in S3. The installer then downloads, un-zips, and executes the actual application installer -- in our case a simple CMD fie.
This setups allows us to have one base AMI and then be able to easily overlay 15+ different application configurations (without having to rebuild the AMI). If you only have one application configuration this may be overkill for your situation.
The only trouble we ran into was having our installer service start to early -- changing the service startup mode to "Automatic Delayed" fixed that issue.
We wrote our boot-strap installer in Java, launched via YAJSW, because we're comfortable with it. If you just want a few simple Unix tools, most are available pre-compiled for Windows, for example wget.
For something completely different, you could try PsExec to configure the instance after it has booted.
You can try using RightScale's free developer account to create plain Powershell scripts and associate them with your Windows instances to run at boot time. The RightScale dashboard solves exactly the problems you are trying to solve above.
DISCLAIMER: I work for RightScale.
As for screen capture CutyCapt is a simple tool you can point at a URL and generate an image from.
Unxutils is a great solution for those looking for unix tools on Windows. It's got the wget.exe that you're looking for, however, using Powershell to download stuff is not so bad either:
$wc = new-object system.net.webclient
$wc.DownloadFile("http://stackoverflow.com","test.html")
If you can write a batch file to do your setup, then you can run it at startup of the vm by doing this:
1. Run REGEDT32.EXE.
2. Modify the following value within HKEY_CURRENT_USER:
Software\Microsoft\Windows NT\CurrentVersion\Winlogon\ParseAutoexec
1 = autoexec.bat is parsed
0 = autoexec.bat is not parsed
As an answer to #3, I would say that you can do just about anything in a batch file that you need which includes downloading from a ftp server (but not from a http server). I am really interested in this stuff and so if you have questions, try asking me.
If you use Elastic Beanstalks you can use this:
Customizing the Software on EC2 Instances Running Windows
It uses YAML formatting standards, e.g.
packages:
msi:
mysql: http://dev.mysql.com/get/Downloads/Connector-Net/mysql-connector-net-6.6.5.msi/from/http://cdn.mysql.com/
or
sources:
"c:/myproject/myapp": http://s3.amazonaws.com/mybucket/myobject.zip
I know this is a little bit late to help out with the original post but for anyone who is still reading this one solution is to use the http://cloudinitnet.codeplex.com/ project. The service is easily installed using a powershell script and will create a local administrator account to use while running.
The goal for this project was to replace the Cloud-Init project used in Amazon Linux and Ubuntu.
