Switching from GitHub Codespaces to Coder
Run `docker run -d -p 7080:7080 -e CODER_HTTP_ADDRESS=0.0.0.0:7080 ghcr.io/coder/coder:latest`. Define a workspace template in Terraform (workspace = a Docker container or k8s pod or AWS instance). `devcontainer.json` from your repo can be referenced directly via the official devcontainer template. Developers connect via browser VS Code, JetBrains Gateway, or `coder ssh` for a local terminal.
