Add a new Quickstart starter template that lets users pick programming
languages, editors, and an optional Git repo to clone. The template uses
Docker under the hood but presents a developer-focused experience: pick
your tools, start coding.
## What's included
- **Languages parameter** (multi-select): Python, Node.js, Go, Rust,
Java, C/C++
- **IDEs parameter** (multi-select): VS Code (Browser), VS Code Desktop,
Cursor, JetBrains, Zed, Windsurf
- **Git repo parameter**: Optional URL to clone on workspace start
- **JetBrains filtering**: Maps selected languages to relevant IDE codes
(Python → PyCharm, Go → GoLand, etc.)
- **Docker precondition check**: Uses `data "external"` +
`terraform_data` precondition to surface a friendly error when Docker is
unavailable, before the Docker provider fails with a cryptic message
- **4 presets**: Web Development, Backend (Go), Data Science, Full Stack
- **Single install script**: All languages install in one `coder_script`
to avoid apt-get lock conflicts (agent scripts run in parallel via
`errgroup`)
<details><summary>Design decisions</summary>
- **Docker as invisible backend**: Docker is required on the Coder
server but never mentioned in the user-facing parameter UI. The
experience is entirely "pick languages, pick editors, start coding."
- **`coder_script` over startup_script**: Language installs use a
templated script file (`install-languages.sh.tftpl`) driven by the
languages parameter. A single script avoids dpkg lock contention since
`coder_script` resources execute concurrently.
- **`data "external"` for Docker check**: The external provider probes
Docker availability independently of the Docker provider. If Docker is
down, the `terraform_data` precondition fails with a human-readable
message before any `docker_*` resource is evaluated. This depends on the
Docker provider connecting lazily (at resource eval time, not at
provider init), which current behavior confirms.
- **JetBrains filtering by language**: Rather than showing all 9
JetBrains IDEs, the template computes relevant IDE codes from the
language selection (e.g. Python → PY, Go → GO) and passes them as
`default` to the JetBrains module.
- **Arch-aware Go install**: The install script detects `uname -m` to
download the correct Go binary for amd64 or arm64.

The existing README for the Azure Linux starter template only mentioned
that the VM is ephemeral and the managed disk is persistent, but did not
explain that the resource group, virtual network, subnet, and network
interface also persist when a workspace is stopped.
This led to confusion where users expected all Azure resources to be
cleaned up on stop, when in reality only the VM is destroyed.
## Changes
- Added the persistent networking/infrastructure resources to the
resource list
- Added "What happens on stop" section explaining which resources
persist and why
- Added "What happens on delete" section confirming all resources are
cleaned up
- Moved the existing note about ephemeral tools/files into a "Workspace
restarts" subsection for clarity
These changes exactly mirror https://github.com/coder/registry/pull/713
since the registry is not yet linked to the starter templates in
`coder/coder`. Once the registry is linked, the starter templates will
pull from the registry and this duplication will no longer be necessary.

This change adds a new `docker-devcontainer` template which allows you
to provision a workspace running in Docker, that also creates workspaces
via Docker running inside (DinD).
- **chore(examples/templates): rename `docker-devcontainer` to
`docker-envbuilder`**
- **feat(examples/templates): add `docker-devcontainer` example
template**
This PR changes template names and docs to follow the
`<provider>-<os/whatever>` format for all templates.
I've decided not to split this into multiple PRs because I'd have to
edit rebase the other PRs once one of them gets merged, this should be
relatively low-impact anyways.
This aligns with our goals to make templates more user-friendly.
Closes#15754
This PR modifies the gcp-devcontainer example template to include
support for devcontainer caching using the envbuilder provider.
