.How to access AWS Cloud9 IDE from VSCode?

Apr 21st 2020-2 min read

There are great benefits from using Cloud9, especially with Terraform, it’s super-fast since the connection to AWS API happens internally, I was facing terraform apply took up to 15 minutes on my machine, now when running the same commands on cloud9 it’s only 15 seconds!

The Cloud9 UI is nice, but you can still VScode with all of your extensions with cloud 9, using remote ssh extension.

How to solve "Visual Studio Code is unable to watch for file changes in this large workspace" (error ENOSPC)?

When you see this notification, it indicates that the VS Code file watcher is running out of handles because the workspace is large and contains many files. The current limit can be viewed by running:

cat /proc/sys/fs/inotify/max_user_watches

The limit can be increased to its maximum by editing /etc/sysctl.conf and adding this line to the end of the file:


The new value can then be loaded in by running sudo sysctl -p.
