octoturge a9583535f0 Add Gitea Actions workflow to auto-provision Coder templates
.gitea/workflows/coder-templates.yml pushes every templates/<env>/ dir
to Coder as profiles-<env> on every push to main that touches
templates/**, scripts/**, or profile-templates/** - coder templates push
creates the template on first run and updates it thereafter, so adding a
new templates/<env>/ directory is enough to provision it, no workflow
edits needed.

It also diffs templates/ against the previous commit and runs
`coder templates delete profiles-<env>` for any directory that was
removed. Deletion fails (loudly, as a job warning, not a hard failure)
rather than succeeding if the template still has active workspaces,
since coder templates delete already refuses that server-side.

Runs on the ubuntu-latest self-hosted Gitea runner already registered on
this instance (confirmed via gitea-runner-1's /data/.runner labels) and
installs the coder CLI itself. Needs CODER_URL and CODER_SESSION_TOKEN
as repo/org Actions secrets - documented in README, left for the user to
set up since token creation needs their own Coder login.

# Profiles-for-Coder
Coder templates for per-discipline dev environments (Default, 3D Printing,
COBOL, Python, TTRPG, Web). Each environment is its own Coder **template** -
not a dropdown inside one shared container, which is what this repo used to
do and which didn't actually work.
## Layout
```
templates/
default/main.tf # Standard Default Dev
3d-printing/main.tf # 3D Printing & Engineering
cobol/main.tf # COBOL Modern Mainframe
python/main.tf # Python Engineering
ttrpg/main.tf # TTRPG & Lore Building
web/main.tf # Web Applications
scripts/
cli-setup-wizard.sh # shared first-run wizard, see below
install-skills.sh # shared Agent Skills installer, see below
profile-templates/ # VS Code .code-profile exports, one per env
extensions/ # Agent Skills bundles, installed per env (see below)
```
Each `templates/<env>/main.tf` is a complete, independent Coder template
(agent, docker container, code-server, JetBrains). They're deliberately not
built from a shared Terraform module - only their `locals` block differs
(which profile file to read). The naming convention is `profiles-<dir>`
(matches what `.gitea/workflows/coder-templates.yml` does automatically -
see below). To push by hand:
```sh
coder templates push profiles-default -d templates/default
coder templates push profiles-3d-printing -d templates/3d-printing
coder templates push profiles-cobol -d templates/cobol
coder templates push profiles-python -d templates/python
coder templates push profiles-ttrpg -d templates/ttrpg
coder templates push profiles-web -d templates/web
```
### How the VS Code profile gets applied
`profile-templates/*.code-profile` is a real VS Code Profile export: a JSON
file whose `settings` and `extensions` fields are themselves JSON-encoded
strings (double/triple-nested). Each template's `main.tf` reads and decodes
its matching file **at `terraform apply`/push time** (via `file()` +
`jsondecode()`), then:
- passes the extension ID list straight into the `code-server` module's
`extensions` input, so code-server installs them on first boot - no
interactive prompt needed, Terraform handles it declaratively;
- writes the raw `settings.json` text (comments and all - VS Code tolerates
JSONC) to `~/.local/share/code-server/User/settings.json` via a
`coder_script`.
This replaces the old approach, which downloaded a zip of this repo from
Gitea *inside* the running container and tried to apply settings from
`~/.local/share/profiles-cache/<profile>.json` - a path that never matched
the actual `.code-profile` file extension, so settings never applied. That
bug (plus the single shared container) is why "one container, many envs"
never really worked.
### Bun
Every template installs [Bun](https://bun.sh) via a `coder_script`
(`curl -fsSL https://bun.sh/install | bash`) and hooks `~/.bun/bin` onto
`PATH` in `~/.bashrc` (the installer doesn't reliably do this itself in a
non-interactive/scripted shell). The CLI setup wizard below uses
`bun install -g <pkg>` instead of `npm install -g <pkg>` for everything it
installs.
### CLI setup wizard
`scripts/cli-setup-wizard.sh` is dropped onto every workspace and hooked
into `~/.bashrc`. It runs in every new interactive terminal - until the user
finishes it - and offers to install + log into:
- **GitHub Copilot CLI** (`bun install -g @github/copilot`, then `copilot login`)
- **Google Antigravity CLI** (`curl -fsSL https://antigravity.google/cli/install.sh | bash`, binary `agy`)
- **Claude Code CLI** (`bun install -g @anthropic-ai/claude-code`, then `claude`)
It does **not** ask about VS Code extensions, since those are handled by
Terraform (see above). Once the user confirms completion it writes a
sentinel file (`~/.cache/coder-cli-wizard/done`) and stops prompting. It can
always be re-run manually: `bash /opt/coder/cli-setup-wizard.sh --force`.
### `extensions/` directory -> Agent Skills
`extensions/awesome-skills-plugin` and `extensions/custom-specialty-plugin`
are **Agent Skills bundles** (`plugin.json` + `SKILL.md` files) - the old
root `main.tf` copied this folder straight into code-server's VS Code
extensions directory, which never worked since these aren't VS Code
extension packages.
Each template now runs `scripts/install-skills.sh` (via a `coder_script`,
pulling a fresh zip of this repo from Gitea rather than embedding ~2.5MB
into Terraform state) to install skills into all three AI CLIs' personal
skills directories:
| CLI | Skills directory |
| --- | --- |
| Claude Code | `~/.claude/skills/<name>/` |
| GitHub Copilot CLI | `~/.copilot/skills/<name>/` |
| Antigravity CLI | `~/.gemini/config/skills/<name>/` (per antigravity.google/docs/skills - some third-party docs disagree on this path, worth a spot-check on a live workspace) |
Every environment gets the full `extensions/awesome-skills-plugin/skills/*`
bundle. On top of that, whichever env has a matching entry in
`extensions/custom-specialty-plugin/skills/` gets it installed too, set via
the `SPECIALTY_SKILLS` env var passed to the script from each template's
`install_skills` `coder_script`:
- COBOL -> `cobol-teacher`
- 3D Printing -> `openscad-parametric`
- TTRPG -> `foundryvtt-modding` and `ttrpg-lore-weaver`
- Default / Python / Web -> none (no matching specialty skill exists yet)
### Auto-provisioning (Gitea Actions)
`.gitea/workflows/coder-templates.yml` keeps Coder in sync with this repo on
every push to `main` that touches `templates/**`, `scripts/**`, or
`profile-templates/**`:
- **Add** a new `templates/<env>/` directory -> next push creates a new
Coder template `profiles-<env>` automatically. No workflow edits needed.
- **Edit** an existing `templates/<env>/main.tf` (or a shared script/profile
it references) -> next push updates that template with a new version.
- **Remove** a `templates/<env>/` directory -> next push deletes
`profiles-<env>` from Coder. `coder templates delete` refuses if the
template still has active workspaces, so this fails loudly instead of
silently orphaning anyone's running workspace - that failure only shows up
as a `::warning::` in the job log, it doesn't fail the whole run.
It runs on the `ubuntu-latest` self-hosted runner already registered on this
Gitea instance and installs the `coder` CLI itself via `coder.com/install.sh`.
**One-time setup required** (not something this workflow can do for itself -
needs a human with Coder access):
1. Create a Coder API token - ideally under a dedicated service account
rather than a personal login, since this token can create/delete
templates:
```sh
coder login https://code.octoturge.com
coder tokens create --name gitea-ci --lifetime 8760h
```
2. In Gitea, go to this repo's **Settings -> Actions -> Secrets** (or the
org-level equivalent to share across repos) and add:
- `CODER_URL` = `https://code.octoturge.com`
- `CODER_SESSION_TOKEN` = the token printed by step 1
Until those secrets exist, the workflow will run and fail cleanly at the
`coder templates push` step rather than doing anything destructive.
