As I stated in the previous post “A Cloud IDE for the masses”, in this post I will explain you how to deploy Code-Server on AWS. But to make it more interesting, I’m going to use AWS Cloud Development Kit (AWS CDK), it is a framework to model and provision your cloud applications and resources using knew programming language (TypeScript, Python, Java, etc.), no more YAML or Json.
We are going to deploy Code-Server (a NodeJS web app) into an EC2 instance, using Ubuntu AMI and provisioning all package through a bash scripts (UserData), as in the below diagram depict it.
Persisting the code
Code-Server doesn’t require a Database, the only thing to persist is the code. The EC2 instance has enough room to download and persist the code and its dependencies like you do it in your local computer. If you have completed your project, then you can push your code to your Git repository.
If you want compile, run your code, or want to process long task, then you will need processing and computing capacity and you will get from EC2 instance you choose. If you need more just run again your IaC with different
EC2 Instance Type. This example uses a
Code-Server is a web application and will require a secure configuration like a standard web application. By default, the only security control that Code-Server is authentication. A fresh Code-Server installation will generate during its installation a password. And considering that, we need implementing extra security around the web application like TLS and/or Mutual TLS Authentication, Whitelisting IP and only open the HTTP/HTTPS port. If you have more time, you could implement a Reverse Proxy with security capabilities or using additional AWS services like AWS API Gateway, AWS CloudFront (WAF), etc.
I already have VSCode, can share my settings, theme and extensions?
Yes, you can do it.
This is the part that I like the most, I’m in love with Settings Sync Extension, only I do configure a Gist ID and Setting Sync automatically download previous VS Code’ settings (theme, style, configuration, etc.) from Gist and install all VS Code extensions for you.
Well, let’s get to the point.
1. CDK installation
$ sudo apt install -y nodejs npm $ sudo npm i -g aws-cdk
2. Install Code-Server on AWS
You don’t have to code anything, I’ve created the AWS CDK project in TypeScript for you, just clone the Git repo and run it.
Before anything configure your AWS account and region:
$ export AWS_ACCESS_KEY_ID="abc" $ export AWS_SECRET_ACCESS_KEY="pqr" $ export AWS_DEFAULT_REGION="us-east-1"
Initialize the CDK project:
$ git clone https://github.com/chilcano/aws-cdk-samples $ cd aws-cdk-samples/code-server-ec2 $ nmp install
If you want to review the CloudFormation code that the CDK project generates, execute this command:
$ cdk synth
And finally, deploy the CDK project:
$ cdk deploy
3. Calling the Code-Server
From your AWS Web Console, get the
Public DNS (IPv4) or
IPv4 Public IP about the EC2 instance created, with that information connect to the host through SSH and get the Code-Server’s password that generates by default:
$ ssh firstname.lastname@example.org -i ~/Downloads/chilcan0.pem ubuntu@ip-10-0-0-117:~$ cat .config/code-server/config.yaml bind-addr: 127.0.0.1:8080 auth: password password: 5995b51c25c621190abd55e8 cert: false
Now, create the SSH tunnel:
$ ssh -nNT -L 8123:localhost:8080 email@example.com -i ~/Downloads/chilcan0.pem
Finally, open the URL http://localhost:8123 in your browser, you should see this:
4. Restoring your VSCode’ settings in Code-Server
I’m using a bash scripts as
userData to install Code-Server and only the Settings-Sync extension that will allow restore a previous Code-Server or VS Code settings, even other extensions. For that you need a Gist ID that your previous Code-Server or VS Code has generated. If you don’t have one, you can use mine.
Settings-Sync Gist ID: b5f88127bd2d89289dc2cd36032ce856
Gist URL: https://gist.github.com/chilcano/b5f88127bd2d89289dc2cd36032ce856
Once restored all Code-Server settings, you will see this:
That’s it. Hope this helps.
