c9-ide

This project aims to provide a containerized Cloud9 IDE environment on top of Cloud9 Core and help you bring up a Cloud9 IDE environment out-of-the-box in on-premise environment or other AWS regions which AWS Cloud9 is not available(e.g. AWS China Ningxia or Beijing region)

Features

• [x] Everything in a single Docker container. A single make run or docker run and you are ready to go.
• [x] Shipped with Caddy as the reverse proxy with the automatic HTTPS capabilities. All traffic goes through SSL/TLS in transit and redirects HTTP to HTTPS.
• [x] Shipped with basic authentication(user/pass) support.
• [x] Docker in Docker support
• [x] Based on Amazon Linux 2 Docker image. You can just yum install anything you need.

Running in AWS China

1. Launch an EC2 instance in public subnet and enabled the public IP address. Make sure the security group has HTTPS(tcp443) wide open(0.0.0.0/0). Don't worry, we will restrict the ACL later.

2. SSH into this EC2 instance and install docker , make and git . In Amazon Linux 2 LTS:

   $ sudo yum install -y docker make git
   $ sudo service docker restart
   $ sudo service docker status (should see active (running))

   clone the repo

   $ git clone https://github.com/pahud/c9-ide.git
   $ cd c9-ide
   // sudo as root
   $ sudo -s

   ECR get-login before we can pull the docker images from ECR in cn-northwest-1. Make sure you specify --registry-ids 937788672844 in the command line.

   $ aws --region cn-northwest-1 ecr get-login --registry-ids 937788672844 --no-include-email | sh
   WARNING! Using --password via the CLI is insecure. Use --password-stdin.
   WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
   Configure a credential helper to remove this warning. See
   https://docs.docker.com/engine/reference/commandline/login/#credentials-store
   
   Login Succeeded
   

   IMPORTANT: make sure your EC2 has attached an IAM role with AmazonEC2ContainerRegistryReadOnly privileges or you may get aws configue error or fail to pull ECR images.

   WARNING: File descriptor limit 1024 is too low for production servers. At least 8192 is recommended. Fix with `ulimit -n 8192`.

   open your browser to http://

   You will immediately see a pop-up window with https:// as the scheme, indicating all trafic is SSL/TLS encrypted in transit. Enter your MYUSERNAME and MYPASSWORD you previously passed in the make command and you will see the Cloud9 welcome page.

   

Clean up

just make clear and the running docker c9-ide container will be removed immediately.

# make clear
c9-ide
# docker ps

Security Concern

1. make sure to update the security group of this EC2 instance and allow your original IP only to reduce the attack surface. If possible, just leave HTTPS only.
2. don't use the default MYUSERNAME and MYPASSWORD, which is defined in the Makefile

FAQ

Q: Can I pull images from Amazon ECR Ningxia or Beijing regions to speed up the pulling?

A: Yes, make sure:

1. your EC2 has attached an IAM role with AmazonEC2ContainerRegistryReadOnly privileges.
2. you need to run ecr get-login to get the docker login credentials

   aws --region cn-northwest-1 ecr get-login --registry-ids 937788672844 --no-include-email | sh

3. toggle USE_ECR=1 to enable the image pulling from Amazon ECR Ningxia region

   USE_ECR=1 DOMAIN=<YOUR_DN> EMAIL=<YOUR_EMAIL> MYUSERNAME=<YOUR_USER> MYPASSWORD=<YOUR_PASS> make run
   (this will pull image straight from ECR in Ningxia region)

Q: Can I run docker inside the IDE(Docker in Docker support)?

A: Yes, see #4

Q: I need some extra tools. What can I do?

A: Just yum install it.
