Securing Visual Studio Code Server
This guide covers using Pomerium to secure an instance of Visual Studio Code Server. Pomerium is an identity-aware access proxy that can add single-sign-on / access control to any service, including visual studio code.
Visual Studio Code
Visual Studio Code is an open source code editor by Microsoft that has become incredibly popular in the last few years. For many developers, Visual Studio Code hits the sweet spot between no frills editors like vim/emacs and full feature IDE's like Eclipse and IntelliJ. VS Code offers some of the creature comforts like intellisense, git integration, and plugins, while staying relatively lightweight.
VS Code Server
Visual Studio Code Server is an open-source project that allows you to run Visual Studio Code on a remote server, through the browser. For example, this is a screenshot taken at the end of this tutorial.
This guide assumes you have already completed one of the quick start guides, and have a working instance of Pomerium up and running. For purpose of this guide, I'm going to use docker-compose, though any other deployment method would work equally well.
# See detailed configuration settings : https://www.pomerium.io/reference/ authenticate_service_url: https://authenticate.corp.domain.example authorize_service_url: https://authorize.corp.domain.example # identity provider settings : https://www.pomerium.io/docs/identity-providers.html idp_provider: google idp_client_id: REPLACE_ME idp_client_secret: REPLACE_ME policy: - from: https://code.corp.domain.example to: http://codeserver:8443 allowed_users: - email@example.com allow_websockets: true
codeserver: image: codercom/code-server:latest restart: always ports: - 8443:8443 volumes: - ./code-server:/home/coder/project command: --allow-http --no-auth --disable-telemetry
Note we are mounting a directory called
./code-server. Be sure to give the default docker user write permissions to that folder by running
chown -R 1000:1000 code-server/.
Simply navigate to your domain (e.g.
(Example) Develop Pomerium in Pomerium
As a final touch, now that we've done all this work we might as well use our new development environment to write some real, actual code. And what better project is there than Pomerium? 😉
wget https://dl.google.com/go/go1.12.7.linux-amd64.tar.gz sudo tar -C /usr/local -xzf go1.12.7.linux-amd64.tar.gz
Then add Go to our PATH.
# add the following to $HOME/.bashrc export PATH=$PATH:/usr/local/go/bin export PATH=$PATH:$(go env GOPATH)/bin
Finally, now that we've got Go all we need to go is grab the latest source and build.
# get the latest source $ git clone https://github.com/pomerium/pomerium.git # grab make $ sudo apt-get install make # build pomerium $ make build # run pomerium! $ ./bin/pomerium --version v0.2.0+e1c00b1
Happy remote hacking!!!😁
