Cloud IDE

Two alternatives that we can use:

  1. Gitpod: Starts at $9/user/mo. Use KEVINHQ for 30% discount for first three months. Users can also share a a running workspace or a snapshot workspace to another user. Based on Eclipse Theia so supports most Visual Studio Code extensions. Supports GitHub, GitLab, and Bitbucket. Paid account is required for private repositories. Spec: 16 Xeon vCPUs, 48 GiB free RAM.
    Note: $10/mo buys you a 2 GB instance on Lightsail or DigitalOcean, that can be used by multiple users.
  2. Coder.com. Open source version is available to host on our own (Lightsail) server.
  3. AWS Cloud9. Pricing is per (running) instance and storage, can be used collaboratively by as many IAM users as needed. Downside is it doesn’t use VS Code / Theia, so many familiar plugins will not work.

Other providers:

  • Codeanywhere. Very popular, not yet tested. Starts from $3/user/mo, to $10/user/mo, and $25/user/mo.
  • OpenShift Che (Codenvy). Formerly Codenvy, now acquired by Red Hat. When tested on July 30, 2020, got connection refused error in sso.redhat.com.

Coder Open Source

Hendy tested this using Amazon EC2 m6g.medium on Tokyo ap-northeast-1b (only ap-northeast-1b and ap-northeast-1c supports m6g instances as of Aug 1, 2020).

  1. Ensure security group ssh-server exists, allowing SSH port from Anywhere
  2. Ensure security group code-server exists, allowing port 8080 (insecure HTTP) from Anywhere
  3. Launch instance using Ubuntu 20.04 Arm, m6g.medium
  4. Install code-server
curl -fsSL https://code-server.dev/install.sh | sh
  1. Edit ~/.config/code-server/config.yaml, change bind-addr from 127.0.0.1 to 0.0.0.0 to expose it to outside world.
bind-addr: 0.0.0.0:8080
auth: password
password: ***
cert: false

Launch code-server daemon using systemctl (user privileges, not using root):

systemctl --user enable --now code-server

Instance Types & Regions Pricing Comparison

Note: 1 GB is unusable for general Node.js development, as running Strapi’s yarn develop crashes the instance even only used by one user.

Installing Development Tools

build-essential

Some Node.js packages and Python packages require build-essential (make, etc.):

sudo apt update && sudo apt -y install build-essential

Node.js 12 & Yarn Classic

Note: We use Node.js 12 because it is the version supported by AWS Lambda. We will upgrade to Node.js 14 after AWS Lambda supports it.

curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo -E npm -g install yarn

Docker / Docker Compose

sudo apt install docker.io
sudo adduser ubuntu docker

You’ll need to relogin the user in order for “docker” group privileges to take effect.

MariaDB

To facilitate better isolation, it’s recommended to use Docker Compose / Docker instead. Each user will still need to use different ports for each service.

sudo apt install mariadb-client
docker run --name mariadb -e MYSQL_ROOT_PASSWORD=password -d -p 3306:3306 mariadb

Creating a new MariaDB database development:

mysql -h127.0.0.1 -uroot -p
CREATE DATABASE lovia_dw_dev CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Troubleshooting

Troubleshooting: UnhandledPromiseRejectionWarning: Error: ENOSPC: System limit for number of file watchers reached

Solution:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
